  61. <h2><a name="1._Pre-requisites"></a>1. Prérequis</h2>
  62. Chamilo peut être installé sous Windows, Linux, Max OS X et serveurs UNIX
  63. indifféremment. Cela dit, nous recommandons activement l'utilisation d'un
  64. serveur Linux pour sa flexibilité optimale, son facile contrôle à distance
  65. et sa capacité de redimensionnement. En particulier, nous recommandons la
  66. distribution Debian (ou sa petite soeur Ubuntu)<br />
  67. <br />
  68. Chamilo est un système de gestion de l'apprentissage (LMS) qui fonctionne
  69. principallement sur base d'un <span style="font-weight: bold;">serveur web (Apache 2.2
  70. recommandé)</span>, de <span style="font-weight: bold;">MySQL (5.1 ou 5.5) ou de MariaDB
  71. (5 ou 10)</span> et de <span style="font-weight: bold;">PHP 5.3, 5.4 ou 5.5 (5.5 recommandé
  72. pour une plus grande efficacité)</span> (la trilogie aussi appelée
  73. <span style="font-weight: bold;">AMP</span>). <br />
  74. <br />
  75. Tous ces éléments logiciels sont sous licence de logiciels libres et sont
  76. disponibles gratuitement.<br />
  77. <br />
  78. Pour faire fonctionner Chamilo <span style="font-weight: bold;">LMS</span> sur votre serveur,
  79. il est suggéré d'installer WAMP, LAMP ou MAMP (ou leurs composants
  80. individuellement):
  81. <ul>
  82. <li>Pour installer <span style="font-weight: bold;">WAMP</span> (AMP sous Windows), nous
  83. recommandons le paquet
  84. <a href="http://www.apachefriends.org/en/xampp.html">XAMPP</a> en
  85. installateur ".exe"</li>
  86. <li>Pour installer <span style="font-weight: bold;">LAMP</span>
  87. (AMP sous Linux), utilisez le système de gestion de paquets de votre
  88. distribution préférée (apt, Synaptic, RPMFinder, yum etc.). Par exemple,
  89. sur un serveur Ubuntu, vous pouvez utiliser le Shell (terminal) ou
  90. Synaptic via le guide
  91. <a href="http://ubuntuguide.org/wiki/Ubuntu:Feisty#Apache_HTTP_Server">
  92. Ubuntuguide on Apache</a> et les sections suivantes du présent guide/li>
  93. <li>Pour installer <span style="font-weight: bold;">MAMP</span> (AMP sur Mac OS X),
  94. référez-vous au site dédié de
  95. <a href="http://www.mamp.info/en/index.php">MAMP</a></li>
  96. <li>Assurez-vous de vérifier les
  97. <a href="dependencies.html" title="Dependencies">dépendances</a> si vous
  98. avez besoin de connaîtres les pré-requis de façon plus précise.
  99. </ul>
  100. <br />
  101. <h3><span style="font-weight: bold;">Serveurs de base de données MySQL ou MariaDB</span></h3>
  102. Vous aurez besoin d'un login et d'un mot de passe pour gérer et créer une base
  103. de données. Généralement, la configuration par défaut sur des ordinateurs
  104. locaux est de permettre la connexion comme utilisateur root avec un mot de passe
  105. vide. Il est FORTEMENT RECOMMANDÉ de modifier le mot de passe et de définir un
  106. utilisateur avec un accès à une (et une seule) base de données spécifique.
  107. Veuillez vous référer à la documentation de MySQL ou MariaDB pour ce faire.
  108. <br />
  109. <span class="muted">Veuillez noter que ceci a été largement simplifié depuis la
  110. version 1.9, étant donné qu'il était nécessaire antérieurement de choisir
  111. entre plusieurs bases de données ou un mode base-de-données-unique
  112. non maintenu..</span><br />
  113. <hr style="width: 100%; height: 2px;" />
  114. <h2><a name="2._Installation_of_Chamilo_LMS"></a><span style="font-weight: bold;">2. Installation de Chamilo LMS</span></h2>
  115. Une fois votre système de base préparé, vous pouvez commencer l'installation de Chamilo proprement dite
  116. <ol>
  117. <li><a href="http://www.chamilo.org/download">Télécharger Chamilo LMS</a></li>
  118. <li>Décompressez-le</li>
  119. <li>Copiez le répertoire de Chamilo dans le répertoire web de votre serveur web (Apache).
  120. Celui-ci peut se trouver dans <span style="font-weight: bold;">C:\xampp\htdocs\</span> sur
  121. une machine Windows avec WAMP, ou dans <span style="font-weight: bold;">/var/www/html/</span> (ou /var/www/) sur un serveur Linux</li>
  122. <li>Ouvrez votre navigateur (Firefox, Chrome, ...) et tapez l'adresse suivante
  123. <span style="font-weight: bold;">http://localhost/chamilo/</span> si vous l'avez installé localement ou
  124. <span style="font-weight: bold;">http://www.domain.com/chamilo/</span> l'avez installé à distance. <span class="muted">Nous recommandons la définition d'un Virtual Host spécifique pour cette installation si vous avez les compétences requises pour configurer votre serveur web</span>
  125. </li>
  126. <li>Suivez le processus d'installation. Vous pouvez accepter toutes les
  127. valeurs par défaut. Pensez à modifier le mot de passe d'administrateur
  128. afin de vous en souvenir plus tard.</li>
  129. </ol>
  130. <br />
  131. <span class="muted">Note: si vous installez Chamilo localement en utilisant
  132. "localhost" ou l'adresse IP de votre ordinateur durant l'installation, vous
  133. pourriez rencontrer des difficultés lors de l'accès depuis d'autres ordinateurs.
  134. Pour éviter ça, vous pouvez
  135. <a href="http://beeznest.wordpress.com/2013/01/15/answering-to-different-addresses-with-chamilo/">appliquer une petite modification à votre
  136. fichier de configuration</a>.</span>
  137. <br /> <br />
  138. Les répertoires suivants doivent êtres lisibles, éditables et exécutables par votre serveur web.
  139. <br />
  140. <span class="muted">Note: Cela ne requiert généralement pas de modification spécifique
  141. sous Windows (ce qui est d'ailleurs l'une des raisons principales pour
  142. l'existence d'autant de virus et malware pour ce système d'exploitation,
  143. mais cela demande l'utilisation de "chmod" sous Linux et Mac. Dans ces
  144. derniers cas, veuillez suivre les instructions qui suivent.</span>
  145. <br /><br />
  146. Remplacez [chamilo] par le répertoire où vous avez placé le contenu du zip:
  147. <ul>
  148. <li>[chamilo]/main/inc/conf/</li>
  149. <li>[chamilo]/main/upload/users/</li>
  150. <li>[chamilo]/main/default_course_document/images/</li>
  151. <li>[chamilo]/archive/</li>
  152. <li>[chamilo]/courses/</li>
  153. <li>[chamilo]/home/</li>
  154. </ul>
  155. Optionnellement, vous pouvez faire la même chose pour les répertoires suivants
  156. si vous souhaitez permettre l'envoi de styles CSS ou la définition de nouvelles
  157. langues par les administrateurs de Chamilo:
  158. <ul>
  159. <li>[chamilo]/main/css/</li>
  160. <li>[chamilo]/main/lang/</li>
  161. </ul>
  162. Depuis Chamilo 1.8.8 (et pour toutes les versions suivantes), vous pouvez
  163. également activer l'indexation full-text, qui requiert l'installation de
  164. l'extension php5-xapian. Si vous l'utilisez, vous devrez autoriser votre système
  165. à écrire dans le répertoire searchdb:
  166. <ul>
  167. <li>[chamilo]/searchdb</li>
  168. </ul>
  169. Si vous trouvez un répertoire tests/ à la racine, veuillez le supprimer.
  170. Il s'agit d'un répertoire de développement qui ne bénéficie pas des
  171. vérifications de sécurité nécessaires pour un système en production. Il ne
  172. devrait en tout cas *jamais* être accessible aux utilisateurs finaux sur un
  173. système en production.
  174. <p>Sous les systèmes d'exploitation Linux, Mac OS X et BSD, vous pouvez utiliser
  175. la commande <em>chmod 0775</em> pour modifier les permissions, bien que nous
  176. recommandions, pour des raisons de sécurité, de cherchez l'assistance d'un
  177. administrateur système expérimenté pour le faire.
  178. Sous Windows, vous pourriez avoir besoin de vérifier les propriétés de ces
  179. répertoires (en cliquant dessus avec le bouton droit de la souris).</p>
  180. <p>Le répertoire suivant doit être lisible et éditable <em>seulement</em>
  181. durant le processus d'installation:</p>
  182. <ul>
  183. <li>chamilo/main/inc/conf/</li>
  184. </ul>
  185. <p>
  186. <b>NOTES:</b><br />
  187. Ne modifiez *pas* les fichiers home/home_*.html directement. Choisissez plutôt
  188. l'option "Configurer la page d'accueil" dans la section d'administration de
  189. Chamilo.</p>
  190. <p><span style="font-weight: bold;">Windows</span> : avec les paquets tout-en-un comme XAMPP,
  191. vous pouvez installer Chamilo facilement. Dans ce cas (et à moins que vous ne
  192. l'utilisiez en production), le mot de passe de MySQL pourrait rester vide.</p>
  193. <p></p>
  194. <h3><strong> Configuration et sécurité après l'installation</strong></h3>
  195. <ul>
  196. <li><strong>Protégez votre répertoire de configuration: </strong>
  197. assurez-vous que personne (à part vous) ne puisse l'éditer.
  198. Vous trouverez le répertoire de configuration dans <em>(chamilo folder)</em>/main/inc/conf.
  199. Rendez-le lisible uniquement (windows/xwindows: click-droit sur le répertoire
  200. pour en éditer les propriétés - Linux/BSD/MacOSX: utilisez la commande "chmod -r 0555".
  201. Le fichier de configuration (main/inc/conf/configuration.php) est créé par votre serveur webThe config
  202. file is created by your web server (Apache + PHP, usually) so you may
  203. need to be root user to change its permissions.</li>
  204. <li><strong>Protégez votre répertoire d'installation: </strong>
  205. si le répertoire <em>[chamilo]</em>/main/install est toujours accessible,
  206. des individus mal intentionnés pourraient (potentiellement) provoquer une
  207. réinstallation par dessus votre installation actuelle (ce qui pourrait se
  208. matérialiser en une perte de données). Pour éviter ça, déplacez le répertoire
  209. ailleurs, changez ses permissions ou supprimez-le, tout simplement, afin que
  210. personne ne puisse y accéder.</li>
  211. <li><strong>Astuces de sécurité: </strong>
  212. rendre tous les fichiers éditables par tout le monde (chmod -r 0777) vous
  213. permettra d'installer Chamilo plus facilement, il est vrai, mais cela permettra
  214. également à d'éventuels individus malintentionés de plus facilement attaquer
  215. votre installation de Chamilo. Il est donc conseillé d'utiliser un utilisateur
  216. système spécifique comme propriétaire de tous les fichiers et répertoires de
  217. Chamilo, et de seulement donner accès au serveur web sur les répertoires et
  218. fichiers énumérés plus haut.
  219. Ces fichiers et répertoires doivent uniquement être accessibles au serveur web,
  220. pas au reste des utilisateurs système sur votre serveur, et encore moins aux
  221. utilisateurs non-identifiés qui tenteraient de se connecter à votre serveur (par
  222. exemple via FTP). Il est aussi recommandé d'empêcher l'interprétation de
  223. fichiers PHP pour tous les répertoires qui autorisent l'écriture par le serveur
  224. web (à part la racine des répertoires de cours).
  225. N'hésitez pas à engager un administrateur système expérimenté pour cela. Cela
  226. peut s'avérer un peu plus cher maintenant, mais vous serez heureux de ne pas
  227. devoir faire façe aux coûts exhorbitants des pertes de données au cas où vous
  228. souffririez l'attaque d'un pirate.</li>
  229. <li><strong>Configurez votre installation de Chamilo: </strong>
  230. dans la section d'administration de Chamilo, vous pouvez utiliser les paramètres
  231. de configuration pour ajuster le comportement de votre installation.</li>
  232. <li><strong>Configurez les mails de Chamilo: </strong>
  233. la plupart des installations de Chamilo utilisent la configuration de mails par
  234. défaut de php.ini. Cependant, si vous utilisez un serveur de mails différent,
  235. vous pourriez avoir besoin d'ajuster les paramètres de mails dans le fichier
  236. <em>[chamilo]</em>/main/inc/conf/mail.conf.php.</li>
  237. <li>Jetez un oeil sur notre<a href="./security.html">guide de sécurité</a> pour plus d'information</li>
  238. </ul>
  239. <br />
  240. <h3>Configuration de PHP</h3>
  241. Pour obtenir le meilleur de votre installation de Chamilo, vous devez configurer vos paramètres PHP: <br />

  313. une version antérieure de Chamilo LMS (1.*) ou de Dok€os (&lt;2.0)</h2>
  314. Avant de mettre à jour, nous recommandons chaudement la prise d'une copie de
  315. sauvegarde de votre installation (répertoires et bases de données).
  316. Si vous ne savez pas comment faire, consultez votre fournisseur d'hébergement
  317. ou un administrateur système qualifié.<br />
  318. <em>Chamilo LMS 1.9 comes with a new database structure in comparison to 1.8.
  319. Although the upgrade script takes the migration in charge, it might be generating
  320. a very heavy load on your server during the upgrade, and will change your
  321. database completely, preserving the data as well as possible (we have tested
  322. the procedure many times, but remember this is GNU/GPLv3 and we cannot be held
  323. responsible for what would happen to your data without professional supervision).
  324. This is why we *really* recommend you take a full backup of your system before
  325. you upgrade.</em>
  326. <br />
  327. <div class="muted"> NOTE: For very heavy Chamilo databases, some of our official
  328. providers have developed improved migration procedures that use more memory but
  329. process the upgrades up to 20 times faster. If this is the kind of thing you
  330. need, we highly recommend you contact them (see reference below).</div>
  331. <div class="muted"> NOTE: This version of Chamilo can only be used to upgrade from
  332. smaller versions of Chamilo or Dok€os. For example, you cannot use the normal
  333. upgrade scripts from Chamilo 1.9 to upgrade from Dok€os 2.0. If you need this,
  334. please contact one of the Chamilo Association's official providers &lt;providers@chamilo.org&gt;)</div>
  335. <p></p>
  336. <h3>3.1 Upgrading from Chamilo 1.9.x (minor upgrade)</h3>
  337. As this is only a minor version change from previous 1.9.* versions of Chamilo, the only thing you need to do is:
  338. <ul>
  339. <li> check that you haven't left any customised stylesheet or image <span class="muted">(if you have, make sure you keep a copy on the side*)</span></li>
  340. <li> download the Chamilo 1.9 install package from the <a href="http://www.chamilo.org/download">Chamilo download page</a></li>
  341. <li> unzip the new files of Chamilo 1.9 over the files of the older version (or unzip the files in one folder and then copy the files from there to the older version's directory)</li>
  342. <li> edit the main/inc/conf/configuration.php file: at the en of the file, locate the previous version number (e.g. '1.9.4') and change it to this new version (e.g. '1.9.8')</li>
  343. <li> you're done! No other upgrade procedure is required</li>
  344. </ul>
  345. <br />
  346. <h3>3.2 Upgrading from Chamilo 1.8.x</h3>
  347. <ul>
  348. <li> check that you haven't left any customised stylesheet or image <span class="muted">(if you have, make sure you keep a copy on the side*)</span></li>
  349. <li> download the Chamilo 1.9 install package from the <a href="http://www.chamilo.org/download">Chamilo download page</a></li>
  350. <li> unzip the new files of Chamilo 1.9 over the files of the older version (or unzip the files in one folder and then copy the files from there to the older version's directory)</li>
  351. <li> point your browser on your portal URL + main/install/</li>
  352. <li> choose your language and click&nbsp;<span style="font-style: italic;">Upgrade from 1.8.x</span></li>
  353. </ul>
  354. <br />
  355. <h3>3.3 Upgrading from Dok€os 1.8.x</h3>
  356. <em>If you upgrade from Dok€os 1.8.x</em> :&nbsp;
  357. <ul>
  358. <li> check that you haven't left any customised stylesheet or image <span class="muted">(if you have, make sure you keep a copy on the side*)</span></li>
  359. <li> download the Chamilo 1.9 install package from the <a href="http://www.chamilo.org/download">Chamilo download page</a></li>

  362. <li> choose your language and click&nbsp;<span style="font-style: italic;">Upgrade from 1.8.x</span></li>
  363. </ul>
  364. A bunch of Chamilo administrators have reported minor issues with the migration between versions considerably apart (like from Dok€os to Chamilo).
  365. This might include loosing some assignments or forum posts. To avoid any ugly effect on your users, we recommend you first establish a checklist
  366. of all the content that is critical to you, and that you keep a working copy of your previous site on the side. This way, it will be easier to
  367. manage the transition by letting your users get access to their contents from the previous site and making it easier for you to compare the two.
  368. If you are experiencing difficulties, consider asking for help from a PHP developer or hiring an <a href="http://www.chamilo.org/en/providers" target="_blank">official Chamilo provider</a>. They will make sure
  369. you get the best our of your Chamilo migration.
  370. <br />
  371. <span class="muted">* Styles and images are located in the main/css or main/img
  372. directories. You can still recover them from your backup if you have made it.
  373. Any modified style or image that uses the default style/image name will be
  374. overwritten by the next step. To avoid loosing your customisations, always
  375. ensure you copy the styles/images under a new name and use and modify the
  376. copy, not the original. The original will always be overwritten by newer
  377. versions. In Dok€os 1.8.5, we have changed the name of several CSS themes.
  378. Backwards compatibility is ensured by the fact that an upgrade only adds the
  379. new themes, but you should try and use these new themes rather than sticking
  380. to the old ones which will be deprecated shortly (not maintained).</span>
  381. <br />
  382. <p></p>
  383. <h3>3.4 Upgrading from Dok€os 1.6.x</h3>
  384. <em>If you upgrade from a lower version of Dok€os (1.6.x)</em>, the first
  385. and most important thing to do is to *move* your current directory to another
  386. place.<br />
  387. An easy way to do that is to create a subdirectory called "old_version"
  388. in your current Chamilo/Dok€os directory and move everything in there using a
  389. simple "move" command (i.e. under Linux: mkdir old_version; mv *
  390. old_verion/), then make the old_version/ directory writeable by the web
  391. server so that courses/ and upload/ directories can be moved from the
  392. old to the new installation.<br />
  393. <br />
  394. The complete process is as follow:
  395. <ul>
  396. <li> move the current Dok€os directory contents to a subdirectory called
  397. <em>old_version</em> and make it writeable by the web server. This
  398. is important to allow the move of the courses/ and upload/ directories
  399. to the new install</li>
  400. <li> download the Chamilo 1.9 install package from the
  401. <a href="http://www.chamilo.org/download">Chamilo download page</a></li>
  402. <li> unzip the new files of Chamilo 1.9 in the main Chamilo/Dok€os directory. The
  403. new directory <em>main</em> should be located directly inside your
  404. Chamilo/Dok€os root folder</li>
  405. <li> point your browser on your portal URL</li>
  406. <li> choose your language and click&nbsp;<span style="font-style: italic;">Upgrade from 1.6.x</span> and confirm the
  407. current directory of the old version</li>
  408. </ul>
  409. <br />
  410. <p class="muted"> NOTE: The upgrade from 1.6.x to 1.8.x implies a revision of
  411. the customised graphics and styles. The new version uses a complete new
  412. set of icons and styles, which means the ones from version 1.6 cannot be
  413. simply reused. The good news is the version 1.8.x allows you to create
  414. your own style in a separate css folder, that you can then reuse through
  415. all the 1.8.x versions
  416. </p>
  417. <p>
  418. <b>WARNING:</b><br />
  419. Do not delete the previous Chamilo/Dok€os installation directory before installing
  420. the new one. When the update is successfully finished, you can remove
  421. the old path.</p>
  422. <p class="muted">
  423. <b>NOTE:</b><br />
  424. Do not modify the home_*.html files directly. Instead,
  425. choose "Configure the homepage" in the Chamilo administration section.</p>
  426. <p></p>
  427. <h3>3.5 In both last cases</h3>
  428. The following directories need to be readable, writeable and executable for the web server:
  429. <ul>
  430. <li>chamilo/main/inc/conf/</li>
  431. <li>chamilo/main/upload/users/</li>
  432. <li>chamilo/main/default_course_document/</li>
  433. <li>chamilo/archive/</li>
  434. <li>chamilo/courses/</li>
  435. <li>chamilo/home/</li>
  436. </ul>
  437. On Linux, Mac OS X and BSD operating systems you can quick-fix this using the
  438. <em>chmod 0777</em> command, but if you are unsure, we recommend you seek advice for
  439. your own OS on <a href="http://www.chamilo.org/forum">our forum</a>.
  440. In Windows, you may need to check the properties of the folders.
  441. <p></p>
  442. <h3>3.6 Quick-upgrade from 1.8.x guide for Linux</h3>
  443. The following quick-upgrade guide assumes that:
  444. <ul>
  445. <li>the Chamilo database username (for MySQL) is "chamilo_db_user" and your login is "chamilo_user"</li>
  446. <li>the chamilo installation is currently in /var/www/chamilo/ and it has 0777 permissions (which is bad, we know, but you'll fix it)</li>
  447. <li>your portal's URL is http://www.portalurl.com/</li>
  448. </ul>
  449. <br />
  450. On the command-line, type:
  451. <ul>
  452. <li>cd /tmp</li>
  453. <li>mysqldump -u chamilo_db_user -p --all-databases --result-file=/home/chamilo_user/chamilo_old.sql</li>
  454. <li>cp -ra /var/www/chamilo /home/chamilo_user/backup_chamilo</li>
  455. <li>mkdir /var/www/chamilo/old_version</li>
  456. <li>mv /var/www/chamilo/* /var/www/chamilo/old_version/</li>
  457. <li>chmod -R 0777 /var/www/chamilo/old_version/</li>
  458. <li>wget http://chamilo.googlecode.com/files/chamilo-1.9.10.tar.gz</li>
  459. <li>tar zxvf chamilo-1.9.10.tar.gz</li>
  460. <li>sudo cp -ra chamilo-1.9.10/* /var/www/chamilo/</li>
  461. <li>rm chamilo-1.9.10.tar.gz</li>
  462. <li>sudo rm -r chamilo-1.9.10/</li>
  463. </ul>
  464. <br />
  465. Then:
  466. <ul>
  467. <li>Direct your browser to http://www.portalurl.com/main/install/</li>
  468. <li>Proceed with the installation</li>
  469. <li>Review the directories permissions</li>
  470. </ul>

  489. <p>
  490. <i>This part is optional, only organisations with an LDAP server will need to read this.</i><br />
  491. An LDAP module is already provided in Chamilo, but it has to be configured to make it work.</p>
  492. <h3><b>Compiling</b></h3>
  493. <p>
  494. Linux servers: It's possible that you have to recompile php with ldap support.
  495. Newer distributions also allow downloading rpms for additional packages.</p>
  496. <h3><b>Activating LDAP in Chamilo</b></h3>
  497. <p class="muted">Note: The LDAP mechanism has been changed in 1.9. As a result, some of the following information might not be correct. Please check
  498. the configuration settings inside Chamilo to learn the details.</p>
  499. <p>
  500. In [Chamilo folder]/main/inc/conf/configuration.conf.php, around line 93, you'll find settings like the following: <br />
  501. // -> Uncomment the two lines below to activate LDAP AND edit main/inc/conf/auth.conf.php for configuration<br />
  502. // $extAuthSource["extldap"]["login"] = $_configuration['root_sys'].$_configuration['code_append']."auth/external_login/login.ldap.php";<br />
  503. // $extAuthSource["extldap"]["newUser"] = $_configuration['root_sys'].$_configuration['code_append']."auth/external_login/newUser.ldap.php";<br />
  504. <br />
  505. remove the // from the last two lines to activate LDAP.<br />
  506. </p>
  507. <h3><b>Settings</b></h3>
  508. <p>
  509. Ask the LDAP server admin for the settings:</p>
  510. <ul>
  511. <li>ldap server name</li>
  512. <li>ldap server port (usually 389)</li>
  513. <li>ldap dc</li>
  514. </ul>
  515. Since 1.8.5, you have to change the LDAP settings inside the "Portal
  516. administration" panel, under "Chamilo configuration settings", section
  517. "LDAP".
  518. <br />
  519. As an example, you should find the following kind of values:<br />
  520. LDAP main server's address: "myldapserver.com"; // your ldap server<br />
  521. LDAP main server's port: 389; // your ldap server's port number<br />
  522. LDAP domain: "dc=xx, dc=yy, dc=zz"; //domain<br />
  523. <br />
  524. <h3><b>Teacher/student status</b></h3>
  525. <p>
  526. By default, Chamilo will check if the "employeenumber" field has a value. If it has, then Chamilo will
  527. consider this user as being a teacher.<br />
  528. If you want to change this behaviour, you can edit main/auth/ldap/authldap.php, function ldap_put_user_info_locally(),
  529. and change the <em>if (empty($info_array[$tutor_field]))</em> condition to whatever suits you.<br />
  530. You can also remove this check by removing the condition and leaving only the <em>$status = STUDENT;</em> line.</p>
  531. <h3><b>Protected LDAP servers</b></h3>
  532. <p>
  533. Some LDAP servers do not support anonymous use of the directory services.<br />
  534. In this case, you should fill in the appropriate fields in the
  535. administration panel (e.g. "manager" and "mypassword") and Chamilo will
  536. try to authenticate using these, or fall back to anonymous mode before
  537. giving up.</p>
  538. <h3>LDAP import into sessions</h3>
  539. <p>There is a new set of scripts now that allow you to insert users
  540. from LDAP directly into a Chamilo session. This, however, relies on a
  541. set of static choices in the LDAP contact attributes.<br />
  542. The fields used intensively by the Chamlio module are:<br />
  543. </p>
  544. <ul>
  545. <li>uid, which is matched to the username in Chamilo</li>
  546. <li>userPassword, which is matched to the user password, although
  547. this part will only work for non-encrypted passwords for now, but it
  548. shouldn't be necessary if using the LDAP server as authentication</li>
  549. <li>ou should end with the year of the person registration or any
  550. criteria you will use to filter users, so that they can be retrieved on
  551. that criteria</li>
  552. <li>sn is used as the lastname field in Chamilo</li>
  553. <li>givenName is used as the firstname field in Chamilo</li>
  554. <li>mail is used as the email field in Chamilo</li>
  555. </ul>
  556. <hr style="width: 100%; height: 2px;" />
  557. <h2><a name="7._Mathematical_formulas"></a>7. Mathematical formulas with LaTeX</h2>
  558. <i>This part is optional, only organisations planning to use mathematical formulas inside the online editor might want to read this.</i><br /><br />
  559. You can enable mathematical equations writing inside the Chamilo online editor (FCKEditor) by applying the following steps:
  560. <ul>
  561. <li>1. Configure your Apache installation to add a cgi-bin directory that contains a symbolic link to the mimetex.cgi in <i>chamilo/main/inc/lib/mimetex/</i> (*see below, step 4)</li>
  562. <li>2. Reload your Apache configuration</li>
  563. <li>3. Edit the online editor's configuration file <i>chamilo/main/inc/lib/fckeditor/myconfig.php</i> and</li>
  564. <ul>
  565. <li>3.1. Enable the mimetex plugin, find the line //$config['LoadPlugin'][] = 'mimetex'; and modify it to be: <b>$config['LoadPlugin'][] = 'mimetex';</b> (remove the double slash)</li>
  566. <li>3.2. The additional settings <b>$config['MimetexExecutableInstalled']</b> , <b>$config['MimetexExecutableDetectionMethod']</b>
  567. and <b>$config['MimetexExecutableDetectionTimeout']</b> are configured for best probability of automatic detection of the installed on the server file <i>mimetex.cgi</i> or <i>mimetex.exe</i>.
  568. In rare cases these options might need to be twicked, see the acccompanying comments about these options within the file <i>myconfig.php</i></li>
  569. <li>3.3. Once the plugin has been activated, almost in all toolbars the corresponding button appears.
  570. If you need to edit some toolbars, see the configuration files (php) within the directory <i>chamilo/main/inc/lib/fckeditor/toolbars/</i> .
  571. Here is an example:
  572. <div class="code">$config['ToolbarSets']['Normal'] = array(<br /> &nbsp;&nbsp;array('FitWindow','Bold','Image','Link','PasteWord','MP3',<b>'mimetex'</b>,'Table','Subscript','Superscript','ShowBlocks')<br />);</div>
  573. The item <b>'mimetex'</b> represents the button, you may add it to or remove it from any toolbar.<br /><br />
  574. </li>
  575. </ul>
  576. <li>4. To install mimetex executable file, make these changes:
  577. <p>Add the corresponding cgi-bin directory to your Apache configuration could be done, in Apache 2, like this:</p>
  578. <div class="code">
  579. ScriptAlias /cgi-bin/ /var/www/cgi-bin/<br />

  586. </div>
  587. <p>Adding a symbolic link can be done, under Windows, by creating a
  588. shortcut to the mimetex.exe file from the cgi-bin directory, or under
  589. Linux by issuing the following command:</p>
  590. <div class="code">
  591. <p>ln -s /var/www/chamilo/main/inc/lib/mimetex/mimetex.cgi /var/www/cgi-bin/mimetex.cgi</p>
  592. </div>
  593. <p>If you are reluctant to modify your Apache configuration, alternately you may do at step 4 the following:
  594. copy mimetex.exe (for windows) or mimetex.cgi (for linux) from <i>chamilo/main/inc/lib/mimetex/</i> directory to your <i>cgi-bin/</i></p>
  595. </li>
  596. <li>5. Make sure that the file mimetex.cgi (or mimetex.exe) has right to be executed by the web-server process. For example, on a Ubuntu Linux system you may write a command like the following:
  597. <div class="code">
  598. sudo chmod a+x mimetex.cgi
  599. </div>
  600. </li>
  601. <li>6. Make sure that the file mimetex.cgi (or mimetex.exe) has been uploaded in <b>BINARY</b> format.
  602. This is another common problem; the fix is just to re-upload the file in ASCII format.
  603. You'll need to consult your FTP program's documentation to figure out how to switch modes.
  604. BINARY mode is used for non-text items, such as executables (*.exe), zip files (*.zip), image files (*.jpg, *.gif) and the like.
  605. ASCII mode needs to be used for text only documents, which includes *.txt, *.cgi, *.pl *.css, *.html, etc.
  606. <br />
  607. You can also try to re upload the mimetex file using the "Upload file" in the "Filemanager" tool in CPanel/Plesk
  608. </li>
  609. </ul>
  610. <p>As a result of this procedure, a new button becomes available in your Chamilo online editor, that gives you possibility
  611. to insert mathematical formulas into your documents.</p>
  612. <hr style="width: 100%; height: 2px;" />
  613. <h2><a name="8._ASCIIMathML_mathematical_formulas"></a>8. Mathematical formulas with ASCIIMathML</h2>
  614. <p>Mathematical formulas may be rendered on web-pages using the script ASCIIMathML.js (a customized version for Chamilo). For more information about this script
  615. and about the ASCIIMath formula syntax see <a href="http://www1.chapman.edu/~jipsen/mathml/asciimath.html">http://www1.chapman.edu/~jipsen/mathml/asciimath.html</a>
  616. and <a href="http://dlippman.imathas.com/asciimathtex/AMT.html">http://dlippman.imathas.com/asciimathtex/AMT.html</a>.</p>
  617. <p>For writing ASCIIMath formulas in documents, a correspondent plugin for the online editor should be activated. For doing this,
  618. see the platform administration section and open the page "Administration &gt; Configuration settings &gt; Editor".
  619. Enable the setting <strong>"ASCIIMathML mathematical editor"</strong>.</p>
  620. <p>Inside documents, the script ASCIIMathML.js renders mathematical formulas in two altrnative ways:</p>
  621. <ul>
  622. <li>By translation ASCIIMath formula notation into MathML code. MathML standard currently is supported by the following browsers:
  623. <ul>
  624. <li>Mozilla Firefox, you may consider installing STIX fonts (<a href="http://www.stixfonts.org">http://www.stixfonts.org</a>) on your client machines for nice looking formulas</li>
  625. <li>Internet Explorer 6 or higher with the add-on MathPlayer 2.0 or higher (<a href="http://www.dessci.com/en/products/mathplayer">http://www.dessci.com/en/products/mathplayer</a>)</li>
  626. <li>Opera 9.5 or higher</li>
  627. </ul>
  628. </li>
  629. <li>For browser that do not support MathML - by translation ASCIIMath formula notation into TeX notation and passing it to
  630. an external service. The external service produces and returns an image that contains the formula. This way is so called
  631. "image-based fallback".
  632. </li>
  633. </ul>
  634. <p>For providing <strong>image-based fallback</strong> in a production system, you should pick up and install on your server software for TeX rendering, such as:</p>
  635. <ul>
  636. <li>mimeTeX - <a href="http://www.forkosh.dreamhost.com/source_mimetex.html">http://www.forkosh.dreamhost.com/source_mimetex.html</a>.
  637. See <a href="#7._Mathematical_formulas">"7. Mathematical formulas with LaTeX"</a> on how to install the mimetex executable file on your server</li>
  638. <li>mathTeX - <a href="http://www.forkosh.com/mathtex.html">http://www.forkosh.com/mathtex.html</a>. Browse the site for installation instructions</li>
  639. </ul>
  640. <p>As an alternative, you may try to use some public services for TeX rendering, such as:</p>
  641. <ul>
  642. <li>MathTran - <a href="http://www.mathtran.org">http://www.mathtran.org</a></li>
  643. <li>Google Chart Tools - <a href="http://code.google.com/apis/charttools">http://code.google.com/apis/charttools</a></li>
  644. </ul>
  645. <p>Open with a text editor the file <strong>.../chamilo/main/inc/lib/asciimath/ASCIIMathML.js</strong>.
  646. Find somewhere at the beginning the line that initializes the variable <strong>AMTcgiloc</strong>.
  647. You may need to alter the setting to be for example:</p>
  648. <ul>
  649. <li><div class="code">var AMTcgiloc = "http://mychamiloserver.org/cgi-bin/mimetex.cgi";</div></li>
  650. <li><div class="code">var AMTcgiloc = "http://mychamiloserver.org/cgi-bin/mathtex.cgi";</div></li>
  651. <li><div class="code">var AMTcgiloc = "http://www.mathtran.org/cgi-bin/mathtran?tex=";</div></li>
  652. <li><div class="code">var AMTcgiloc = "http://chart.googleapis.com/chart?cht=tx&amp;chs=1x0&amp;chl=";</div></li>
  653. <li>... or something else</li>
  654. </ul>
  655. <p>For testing how the variable <strong>AMTcgiloc</strong> may be set, there are some examples (as comments) inside the script.</p>
  656. <hr style="width: 100%; height: 2px;" />
  657. <h2><a name="9._WIRIS_mathematical_formulas"></a>9. Mathematical formulas with WIRIS</h2>
  658. <p>Installing this plugin you get WIRIS editor and WIRIS CAS. <br/>
  659. This activation will not be completed unless you have previously downloaded the <a href="http://www.wiris.com/plugins/editors/download?filter=fckeditor" target="_blank">PHP plugin for FCKeditor WIRIS</a> and unzipped its contents into the main/inc/lib/fckeditor/editor/plugins/fckeditor_wiris/ directory. <br/>This is necessary because Wiris is proprietary software and its services are <a href="http://www.wiris.com/store/who-pays" target="_blank">commercial</a>. To make adjustments to the plugin, edit configuration.ini file or replace his content by configuration.ini.default Chamilo file.</p>

  661. <h2><a name="10._Xapian_fulltext_indexing"></a>Full-text indexation with Xapian</h2>
  662. <p>
  663. <em>Note</em>: This step will require a dedicated server or a virtual dedicated server as the packages involved are not available on most shared hosting solutions.<br />
  664. On Debian or Ubuntu 10.04 and superior, you will simply need to install the php5-xapian package and restart your web server:
  665. <pre>
  666. sudo apt-get install php5-xapian
  667. sudo /etc/init.d/apache2 restart
  668. </pre>
  669. Then go to your administration page -&gt; Configuration settings -&gt; Search
  670. and enable the search tool. Follow the recommendations on the page to get the
  671. complete indexing suite installed. Once you're done, all documents you import
  672. into your Chamilo portal in a recognized format will be indexed and searchable.
  673. Chamilo Administrators training (which you can ask any <a href="http://www.chamilo.org/en/providers">Chamilo's Official
  674. Provider</a> for) include a full review of the full-text search feature.

  678. <p>
  679. <em>Note</em>: This step will require a dedicated server or a virtual dedicated server as the packages involved are not available on most shared hosting solutions.<br />
  680. On Debian or Ubuntu 11.10 and superior, install LibreOffice.org v3 and start it as a headless server:
  681. <pre>
  682. sudo apt-get install libreoffice
  683. sudo soffice -accept="socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp;" -headless -nodefault -nofirststartwizard -nolockcheck -nologo -norestore &amp;
  684. </pre>
  685. Then go to your administration page -&gt; <i>Chamilo Rapid</i> and set the host to "localhost" and the port to "2002". Save. Go to your course, learning path tool and see the new icon appeared. Import your PPT. This should work.
  686. <em>Note</em>: Sometimes, this doesn't work out so easily. You can probably ask for the assistance of any system administrator around with a bit of Java and PHP experience, or you can always ask one of the Chamilo's Official Providers for assistance (ask for a guaranteed commercial contract).

  688. <hr style="width: 100%; height: 2px;" />
  689. <h2><a name="12._Setting_cron_up"></a>Setting chronological tasks</h2>
  690. <p>
  691. Since Chamilo 1.8.8, a few tasks need to be executed regularly in order to get
  692. the best out of your server resources. One of such tasks (and the only one
  693. around at the time of Chamilo 1.8.8) is the sending of internal messaging
  694. notifications by e-mail, i.e. when you receive an e-mail from another person or
  695. from a group inside the internal messaging system of Chamilo, if all e-mails are
  696. sent immediately, then you might not have the chance to receive them at your
  697. pace, once a day or even once a week. For cases like this you, as a Chamilo
  698. administrator, should setup a cron process on the server to check the queue of
  699. e-mails and send is timely.</p>
  700. <p>
  701. Setting up a cron task is easy and there are several ways to do it. We recommend
  702. you have a look at the <a href="http://drupal.org/cron">Drupal documentation
  703. for setting up cron</a> and define your own cron process as:
  704. <pre>
  705. 35 * * * * wget -O - -q -t 1 http://campus.example.com/main/cron/run.php
  706. </pre>
  707. Make sure you have a look into run.php as maybe you want to change a few
  708. settings there.
  709. </p>
  710. <hr style="width: 100%; height: 2px;" />
  711. <h2><a name="13._Changing_language_names_order"></a>Changing the language's firstname/lastname order</h2>
  712. <p>
  713. As Chamilo becomes more popular and crosses many borders now, it frequently happens that administrators want to re-order the firstname and lastname fields in tables, and also on which field it is sorted first.<br/><br />
  714. This can easily be modified by editing the main/inc/lib/internationalization_database/name_order_conventions.php file, finding your language and changing the fields. It is pretty self-explanatory and looks like this:<br />
  715. <pre>'simpl_chinese' => array( 'format' => 'title last_name first_name', 'sort_by' => 'last_name' ), // Eastern order</pre><br />
  716. Feel free to change this to<br />
  717. <pre>'simpl_chinese' => array( 'format' => 'title first_name lastname', 'sort_by' => 'last_name' ), // Eastern order</pre><br />
  718. for example. The effect should be immediate.
  719. </p>
  720. <hr style="width: 100%; height: 2px;" />
  721. <h2><a name="14._Improving_files_download"></a>Improving files download efficiency</h2>
  722. <p>
  723. File download can be very slow when passing through a PHP script to control permissions. One solution to this
  724. is to use the X-Sendfile header, which depends on a module on the webserver. <a href="http://stackoverflow.com/a/3731639/1406662">Check http://stackoverflow.com/a/3731639/1406662 for more details on implementing Sendfile</a>.
  725. Chamilo LMS 1.9.8 (and following versions) supports the X-Sendfile headers, but requires a specific line of configuration to be
  726. added to configuration.php:
  727. <pre>
  728. $_configuration['enable_x_sendfile_headers'] = true;
  729. </pre>
  730. If you have issues with files taking a long time to download, make sure you reconfigure your webserver and add this line. You should see an notable difference in download time.
