<p>Ce guide explique comment installer Chamilo LMS. Nous recommandons activement la lecture complète de ce guide avant de commencer l'installation.</p>
<p>English: Get back to the <ahref="installation_guide.html">English version of the installation guide</a>.</p>
<li>Copiez le répertoire de Chamilo dans le répertoire web de votre serveur web (Apache).
Celui-ci peut se trouver dans <spanstyle="font-weight: bold;">C:\xampp\htdocs\</span> sur
une machine Windows avec WAMP, ou dans <spanstyle="font-weight: bold;">/var/www/html/</span> (ou /var/www/) sur un serveur Linux</li>
<li>Ouvrez votre navigateur (Firefox, Chrome, ...) et tapez l'adresse suivante
<spanstyle="font-weight: bold;">http://localhost/chamilo/</span> si vous l'avez installé localement ou
<spanstyle="font-weight: bold;">http://www.domain.com/chamilo/</span> l'avez installé à distance. <spanclass="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>
</li>
<li>Suivez le processus d'installation. Vous pouvez accepter toutes les
valeurs par défaut. Pensez à modifier le mot de passe d'administrateur
afin de vous en souvenir plus tard.</li>
</ol>
<br/>
<spanclass="muted">Note: si vous installez Chamilo localement en utilisant
"localhost" ou l'adresse IP de votre ordinateur durant l'installation, vous
pourriez rencontrer des difficultés lors de l'accès depuis d'autres ordinateurs.
Pour éviter ça, vous pouvez
<ahref="http://beeznest.wordpress.com/2013/01/15/answering-to-different-addresses-with-chamilo/">appliquer une petite modification à votre
fichier de configuration</a>.</span>
<br/><br/>
Les répertoires suivants doivent êtres lisibles, éditables et exécutables par votre serveur web.
<br/>
<spanclass="muted">Note: Cela ne requiert généralement pas de modification spécifique
sous Windows (ce qui est d'ailleurs l'une des raisons principales pour
l'existence d'autant de virus et malware pour ce système d'exploitation,
mais cela demande l'utilisation de "chmod" sous Linux et Mac. Dans ces
derniers cas, veuillez suivre les instructions qui suivent.</span>
<br/><br/>
Remplacez [chamilo] par le répertoire où vous avez placé le contenu du zip:
<li>cherchez les mots contenant "_max" et augmentez les valeurs correspondantes
pour permettre au serveur de gérer des fichiers plus grands et des requêtes plus lourdes</li>
<li>nous recommandons les valeurs suivantes : </li>
</ul>
<divclass="code">
max_execution_time = 300 ;Maximum execution time of each script, in seconds<br/>
max_input_time = 600 ;Maximum amount of time each script may spend parsing request data<br/>
memory_limit = 256M ;Maximum amount of memory a script may consume (128MB)<br/>
post_max_size = 100M<br/>
upload_max_filesize = 100M<br/>
</div>
<p>Certains de nos utilisateurs ont rencontré des problèmes parce que leurs
paramètres de configuration ne correspondaient pas dans les cas suivants (valeurs recommandées):</p>
<ul>
<li>short_open_tag = Off</li>
<li>safe_mode = Off</li>
<li>magic_quotes_gpc = Off</li>
<li>magic_quotes_runtime = Off</li>
</ul>
<p>
Certaines versions antérieures de Chamilo exigeaient que register_globals soit
configuré à On. Ce n'est plus le cas depuis bien longtemps et ce paramètres
devrait désormais être configuré à Off (bien que les dernières versions de PHP
ne proposent même plus ce paramètre de configuration et le mettent d'office à Off).
<spanclass="muted">L'activation du register_globals est désormais largement considérée comme un mauvais choix au niveau sécurité.</a></p>
<p><strong>Note:</strong> si vous utilisez PHP 5.3 ou supérieur, vous
<em>devez</em> configurer le paramètre <em>date.timezone</em> à la zone horaire
de votre serveur. Par exemple, si votre serveur est dans la zone horaire
'America/New_York', configurez-le de la manière suivante dans votre php.ini:</p>
<divclass="code">
date.timezone = 'America/New_York'
</div>
<p><strong>Note:</strong> PHP 5.3.9 introduit un nouveau paramètre appelé
"max_input_vars", qui limite le nombre d'éléments que vous pouvez envoyer au
travers d'un formulaire déterminé. Si vous devez gérer de grandes quantités
d'utilisateurs ou de longs parcours d'apprentissage (de nombreux éléments),
assurez-vous de configurer ce paramètre plus haut que se valeur par défault
de 1000.</p>
<p><strong>Utilisateurs de BSD:</strong> les librairies suivantes doivent être
inclues durant l'installation de PHP:</p>
<ul>
<li>php5-mysql (or php5-mysqlnd) The mysql shared extension for php</li>
<li>php5-pcre The pcre shared extension for php</li>
<li>php5-session The session shared extension for php</li>
<li>php5-zlib The zlib shared extension for php</li>
<li>php5-gd The graphics-generation extension for php</li>
<li>php5-intl The international behaviours extension for php</li>
<li>(optional) php5-ldap if you want to be able to use LDAP authentication</li>
</ul>
<p>Nous recommandons aussi les extensions suivantes:</p>
<ul>
<li>php5-ctype</li>
<li>php5-iconv</li>

<h2><aname="3._Upgrade_from_a_previous_version_of"></a>3. Mettre à jour depuis
une version antérieure de Chamilo LMS (1.*) ou de Dok€os (<2.0)</h2>
Avant de mettre à jour, nous recommandons chaudement la prise d'une copie de
sauvegarde de votre installation (répertoires et bases de données).
Si vous ne savez pas comment faire, consultez votre fournisseur d'hébergement
ou un administrateur système qualifié.<br/>
<em>Chamilo LMS 1.9 comes with a new database structure in comparison to 1.8.
Although the upgrade script takes the migration in charge, it might be generating
a very heavy load on your server during the upgrade, and will change your
database completely, preserving the data as well as possible (we have tested
the procedure many times, but remember this is GNU/GPLv3 and we cannot be held
responsible for what would happen to your data without professional supervision).
This is why we *really* recommend you take a full backup of your system before
you upgrade.</em>
<br/>
<divclass="muted"> NOTE: For very heavy Chamilo databases, some of our official
providers have developed improved migration procedures that use more memory but
process the upgrades up to 20 times faster. If this is the kind of thing you
need, we highly recommend you contact them (see reference below).</div>
<divclass="muted"> NOTE: This version of Chamilo can only be used to upgrade from
smaller versions of Chamilo or Dok€os. For example, you cannot use the normal
upgrade scripts from Chamilo 1.9 to upgrade from Dok€os 2.0. If you need this,
please contact one of the Chamilo Association's official providers <providers@chamilo.org>)</div>
<p></p>
<h3>3.1 Upgrading from Chamilo 1.9.x (minor upgrade)</h3>
As this is only a minor version change from previous 1.9.* versions of Chamilo, the only thing you need to do is:
<ul>
<li> check that you haven't left any customised stylesheet or image <spanclass="muted">(if you have, make sure you keep a copy on the side*)</span></li>
<li> download the Chamilo 1.9 install package from the <ahref="http://www.chamilo.org/download">Chamilo download page</a></li>
<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>
<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>
<li> you're done! No other upgrade procedure is required</li>
</ul>
<br/>
<h3>3.2 Upgrading from Chamilo 1.8.x</h3>
<ul>
<li> check that you haven't left any customised stylesheet or image <spanclass="muted">(if you have, make sure you keep a copy on the side*)</span></li>
<li> download the Chamilo 1.9 install package from the <ahref="http://www.chamilo.org/download">Chamilo download page</a></li>
<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>
<li> point your browser on your portal URL + main/install/</li>
<li> choose your language and click <spanstyle="font-style: italic;">Upgrade from 1.8.x</span></li>
</ul>
<br/>
<h3>3.3 Upgrading from Dok€os 1.8.x</h3>
<em>If you upgrade from Dok€os 1.8.x</em> :
<ul>
<li> check that you haven't left any customised stylesheet or image <spanclass="muted">(if you have, make sure you keep a copy on the side*)</span></li>
<li> download the Chamilo 1.9 install package from the <ahref="http://www.chamilo.org/download">Chamilo download page</a></li>
<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>
<li> point your browser on your portal URL + main/install/</li>
<li> choose your language and click <spanstyle="font-style: italic;">Upgrade from 1.8.x</span></li>
</ul>
A bunch of Chamilo administrators have reported minor issues with the migration between versions considerably apart (like from Dok€os to Chamilo).
This might include loosing some assignments or forum posts. To avoid any ugly effect on your users, we recommend you first establish a checklist
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
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.
If you are experiencing difficulties, consider asking for help from a PHP developer or hiring an <ahref="http://www.chamilo.org/en/providers"target="_blank">official Chamilo provider</a>. They will make sure
you get the best our of your Chamilo migration.
<br/>
<spanclass="muted">* Styles and images are located in the main/css or main/img
directories. You can still recover them from your backup if you have made it.
Any modified style or image that uses the default style/image name will be
overwritten by the next step. To avoid loosing your customisations, always
ensure you copy the styles/images under a new name and use and modify the
copy, not the original. The original will always be overwritten by newer
versions. In Dok€os 1.8.5, we have changed the name of several CSS themes.
Backwards compatibility is ensured by the fact that an upgrade only adds the
new themes, but you should try and use these new themes rather than sticking
to the old ones which will be deprecated shortly (not maintained).</span>
<br/>
<p></p>
<h3>3.4 Upgrading from Dok€os 1.6.x</h3>
<em>If you upgrade from a lower version of Dok€os (1.6.x)</em>, the first
and most important thing to do is to *move* your current directory to another
place.<br/>
An easy way to do that is to create a subdirectory called "old_version"
in your current Chamilo/Dok€os directory and move everything in there using a
simple "move" command (i.e. under Linux: mkdir old_version; mv *
old_verion/), then make the old_version/ directory writeable by the web
server so that courses/ and upload/ directories can be moved from the
old to the new installation.<br/>
<br/>
The complete process is as follow:
<ul>
<li> move the current Dok€os directory contents to a subdirectory called
<em>old_version</em> and make it writeable by the web server. This
is important to allow the move of the courses/ and upload/ directories
to the new install</li>
<li> download the Chamilo 1.9 install package from the
remove the // from the last two lines to activate LDAP.<br/>
</p>
<h3><b>Settings</b></h3>
<p>
Ask the LDAP server admin for the settings:</p>
<ul>
<li>ldap server name</li>
<li>ldap server port (usually 389)</li>
<li>ldap dc</li>
</ul>
Since 1.8.5, you have to change the LDAP settings inside the "Portal
administration" panel, under "Chamilo configuration settings", section
"LDAP".
<br/>
As an example, you should find the following kind of values:<br/>
LDAP main server's address: "myldapserver.com"; // your ldap server<br/>
LDAP main server's port: 389; // your ldap server's port number<br/>
LDAP domain: "dc=xx, dc=yy, dc=zz"; //domain<br/>
<br/>
<h3><b>Teacher/student status</b></h3>
<p>
By default, Chamilo will check if the "employeenumber" field has a value. If it has, then Chamilo will
consider this user as being a teacher.<br/>
If you want to change this behaviour, you can edit main/auth/ldap/authldap.php, function ldap_put_user_info_locally(),
and change the <em>if (empty($info_array[$tutor_field]))</em> condition to whatever suits you.<br/>
You can also remove this check by removing the condition and leaving only the <em>$status = STUDENT;</em> line.</p>
<h3><b>Protected LDAP servers</b></h3>
<p>
Some LDAP servers do not support anonymous use of the directory services.<br/>
In this case, you should fill in the appropriate fields in the
administration panel (e.g. "manager" and "mypassword") and Chamilo will
try to authenticate using these, or fall back to anonymous mode before
giving up.</p>
<h3>LDAP import into sessions</h3>
<p>There is a new set of scripts now that allow you to insert users
from LDAP directly into a Chamilo session. This, however, relies on a
set of static choices in the LDAP contact attributes.<br/>
The fields used intensively by the Chamlio module are:<br/>
</p>
<ul>
<li>uid, which is matched to the username in Chamilo</li>
<li>userPassword, which is matched to the user password, although
this part will only work for non-encrypted passwords for now, but it
shouldn't be necessary if using the LDAP server as authentication</li>
<li>ou should end with the year of the person registration or any
criteria you will use to filter users, so that they can be retrieved on
that criteria</li>
<li>sn is used as the lastname field in Chamilo</li>
<li>givenName is used as the firstname field in Chamilo</li>
<li>mail is used as the email field in Chamilo</li>
</ul>
<hrstyle="width: 100%; height: 2px;"/>
<h2><aname="7._Mathematical_formulas"></a>7. Mathematical formulas with LaTeX</h2>
<i>This part is optional, only organisations planning to use mathematical formulas inside the online editor might want to read this.</i><br/><br/>
You can enable mathematical equations writing inside the Chamilo online editor (FCKEditor) by applying the following steps:
<ul>
<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>
<li>2. Reload your Apache configuration</li>
<li>3. Edit the online editor's configuration file <i>chamilo/main/inc/lib/fckeditor/myconfig.php</i> and</li>
<ul>
<li>3.1. Enable the mimetex plugin, find the line //$config['LoadPlugin'][] = 'mimetex'; and modify it to be: <b>$config['LoadPlugin'][] = 'mimetex';</b> (remove the double slash)</li>
<li>3.2. The additional settings <b>$config['MimetexExecutableInstalled']</b> , <b>$config['MimetexExecutableDetectionMethod']</b>
and <b>$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>.
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>
<li>3.3. Once the plugin has been activated, almost in all toolbars the corresponding button appears.
If you need to edit some toolbars, see the configuration files (php) within the directory <i>chamilo/main/inc/lib/fckeditor/toolbars/</i> .
<p>If you are reluctant to modify your Apache configuration, alternately you may do at step 4 the following:
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>
</li>
<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:
<divclass="code">
sudo chmod a+x mimetex.cgi
</div>
</li>
<li>6. Make sure that the file mimetex.cgi (or mimetex.exe) has been uploaded in <b>BINARY</b> format.
This is another common problem; the fix is just to re-upload the file in ASCII format.
You'll need to consult your FTP program's documentation to figure out how to switch modes.
BINARY mode is used for non-text items, such as executables (*.exe), zip files (*.zip), image files (*.jpg, *.gif) and the like.
ASCII mode needs to be used for text only documents, which includes *.txt, *.cgi, *.pl *.css, *.html, etc.
<br/>
You can also try to re upload the mimetex file using the "Upload file" in the "Filemanager" tool in CPanel/Plesk
</li>
</ul>
<p>As a result of this procedure, a new button becomes available in your Chamilo online editor, that gives you possibility
to insert mathematical formulas into your documents.</p>
<hrstyle="width: 100%; height: 2px;"/>
<h2><aname="8._ASCIIMathML_mathematical_formulas"></a>8. Mathematical formulas with ASCIIMathML</h2>
<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
and about the ASCIIMath formula syntax see <ahref="http://www1.chapman.edu/~jipsen/mathml/asciimath.html">http://www1.chapman.edu/~jipsen/mathml/asciimath.html</a>
and <ahref="http://dlippman.imathas.com/asciimathtex/AMT.html">http://dlippman.imathas.com/asciimathtex/AMT.html</a>.</p>
<p>For writing ASCIIMath formulas in documents, a correspondent plugin for the online editor should be activated. For doing this,
see the platform administration section and open the page "Administration > Configuration settings > Editor".
Enable the setting <strong>"ASCIIMathML mathematical editor"</strong>.</p>
<p>Inside documents, the script ASCIIMathML.js renders mathematical formulas in two altrnative ways:</p>
<ul>
<li>By translation ASCIIMath formula notation into MathML code. MathML standard currently is supported by the following browsers:
<ul>
<li>Mozilla Firefox, you may consider installing STIX fonts (<ahref="http://www.stixfonts.org">http://www.stixfonts.org</a>) on your client machines for nice looking formulas</li>
<li>Internet Explorer 6 or higher with the add-on MathPlayer 2.0 or higher (<ahref="http://www.dessci.com/en/products/mathplayer">http://www.dessci.com/en/products/mathplayer</a>)</li>
<li>Opera 9.5 or higher</li>
</ul>
</li>
<li>For browser that do not support MathML - by translation ASCIIMath formula notation into TeX notation and passing it to
an external service. The external service produces and returns an image that contains the formula. This way is so called
"image-based fallback".
</li>
</ul>
<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>
<p>For testing how the variable <strong>AMTcgiloc</strong> may be set, there are some examples (as comments) inside the script.</p>
<hrstyle="width: 100%; height: 2px;"/>
<h2><aname="9._WIRIS_mathematical_formulas"></a>9. Mathematical formulas with WIRIS</h2>
<p>Installing this plugin you get WIRIS editor and WIRIS CAS. <br/>
This activation will not be completed unless you have previously downloaded the <ahref="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 <ahref="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>
<hrstyle="width: 100%; height: 2px;"/>
<h2><aname="10._Xapian_fulltext_indexing"></a>Full-text indexation with Xapian</h2>
<p>
<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/>
On Debian or Ubuntu 10.04 and superior, you will simply need to install the php5-xapian package and restart your web server:
<pre>
sudo apt-get install php5-xapian
sudo /etc/init.d/apache2 restart
</pre>
Then go to your administration page -> Configuration settings -> Search
and enable the search tool. Follow the recommendations on the page to get the
complete indexing suite installed. Once you're done, all documents you import
into your Chamilo portal in a recognized format will be indexed and searchable.
Chamilo Administrators training (which you can ask any <ahref="http://www.chamilo.org/en/providers">Chamilo's Official
Provider</a> for) include a full review of the full-text search feature.
<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/>
On Debian or Ubuntu 11.10 and superior, install LibreOffice.org v3 and start it as a headless server:
<pre>
sudo apt-get install libreoffice
sudo soffice -accept="socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp;" -headless -nodefault -nofirststartwizard -nolockcheck -nologo -norestore &
</pre>
Then go to your administration page -><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.
<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).
Make sure you have a look into run.php as maybe you want to change a few
settings there.

<hrstyle="width: 100%; height: 2px;"/>
<h2><aname="13._Changing_language_names_order"></a>Changing the language's firstname/lastname order</h2>
<p>
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/>
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/>
File download can be very slow when passing through a PHP script to control permissions. One solution to this
is to use the X-Sendfile header, which depends on a module on the webserver. <ahref="http://stackoverflow.com/a/3731639/1406662">Check http://stackoverflow.com/a/3731639/1406662 for more details on implementing Sendfile</a>.
Chamilo LMS 1.9.8 (and following versions) supports the X-Sendfile headers, but requires a specific line of configuration to be
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.
