Chamilo is mainly a LMS running <spanstyle="font-weight: bold;">Apache (2.2 recommended)</span>, <spanstyle="font-weight: bold;">MySQL 5.1 or 5.5 (or MariaDB)</span> and <spanstyle="font-weight: bold;">PHP 5.3, 5.4 or 5.5 (5.5 recommended for greater efficiency)</span> (the so called <spanstyle="font-weight: bold;">AMP</span> trilogy). <br/>
<li>To install <spanstyle="font-weight: bold;">WAMP</span> (AMP on Windows), we recommend the <ahref="http://www.apachefriends.org/en/xampp.html">XAMPP</a> .exe installer<ahref="http://www.apachefriends.org/en/xampp.html"></a></li>
(AMP on Linux), use the Package manager of your favourite distribution (Synaptic, RPMFinder etc.).
For instance, on a Ubuntu server, use Shell or Synaptic following the

<spanstyle="font-weight: bold;">http://www.domain.com/chamilo/</span> if you install remotely. <spanclass="muted">We recommend defining a specific Virtual Host for this installation if you have the skills to do so</span>

<p><strong>Note:</strong> PHP 5.3.9 introduces a new setting "max_input_vars", which limits the number of elements you can send in one single form. If you are dealing with numerous users or very long learning paths (many items), make sure you set this setting higher than its default value of 1000.</p>
<divclass="muted"> NOTE: This version of Chamilo can only be used to upgrade from earlier 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 (which was born after the split with Chamilo). If you need this, please contact one of the Chamilo Association's <ahref="https://chamilo.org/providers">official providers</a>)</div>

<li> clean your archive/ directory: take a temporary copy of index.html, delete all the contents *in* this directory (do NOT remove the directory itself, only its contents!).

<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>
<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>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.
<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,
<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
<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>
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>
<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:
<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/>
Please note that this will effectively launch LibreOffice in a "headless" mode (thanks to the --headless option), in a "headless" terminal (thanks to screen). You can later get back into your "headless" terminal by launching:
<pre>
sudo screen -r
</pre>
You can 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). The above is *not* meant for production servers with a high load. You should get a real system administrator to look at it and develop init scripts, in a way that makes monitoring and relaunching feasable. If any sysadmin wants to contribute this, feel free to contribute it to Chamilo: send us an e-mail at info@chamilo.org.
<em>Note</em>: If you use LibreOffice 4, please note that version 4.2 (available in Ubuntu 14.04) has demonstrated to be more successfull at converting documents than version 4.1, which tended to crash when sending a document for conversion.
<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.
