<h2><a name="1._Pre-requisites"></a>1. Pre-requisites</h2>
|
|
|
|
Chamilo
|
|
can be installed on Windows, Linux, Mac OS X and UNIX servers
|
|
indifferently. However, we recommend the use of Linux server for
|
|
optimal flexibility, remote control and scalability. <br />
|
|
|
|
<br />
|
|
|
|
Chamilo is mainly a LMS running <span style="font-weight: bold;">Apache 1.3, 2.0</span>, <span style="font-weight: bold;">MySQL 5.1</span> and <span style="font-weight: bold;">PHP 5.1</span> (the so called <span style="font-weight: bold;">AMP</span> trilogy). <br />
|
|
|
|
|
|
<br />
|
|
|
|
All these software are open source and freely available. <br />
|
|
|
|
<br />
|
|
|
|
To run Chamilo <span style="font-weight: bold;">LMS</span> on your server, you need to install WAMP, LAMP or MAMP:
|
|
<ul>
|
|
|
|
<li>To install <span style="font-weight: bold;">WAMP</span> (AMP on Windows), we recommend the <a href="http://www.apachefriends.org/en/xampp.html">XAMPP</a> .exe installer<a href="http://www.apachefriends.org/en/xampp.html"></a></li>
|
|
|
|
<li>To install <span style="font-weight: bold;">LAMP</span>
|
|
(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
|
|
<a href="http://ubuntuguide.org/wiki/Ubuntu:Feisty#Apache_HTTP_Server">Ubuntuguide on Apache</a> and the following sections</li>
|
|
|
|
<li>To install <span style="font-weight: bold;">MAMP</span> (AMP on Mac OS X), refer to the <a href="http://www.mamp.info/en/index.php">MAMP</a> dedicated website<a href="http://www.mamp.info/en/index.php"></a></li>
|
|
</ul>
|
|
|
|
|
|
<br />
|
|
|
|
|
|
<h3><span style="font-weight: bold;">MySQL database server</span></h3>
|
|
|
|
You will need a login and password allowing to administrate and create
|
|
at least one database. By default, Chamilo will create a new database
|
|
for each course created. It means your host should allow you to create
|
|
and administrate several databases. You can also install Chamilo using
|
|
only one database, in that case you have to select this option during
|
|
the installation.<span style="font-weight: bold;"><br />

<h2><a name="2._Installation_of_Chamilo_LMS"></a><span style="font-weight: bold;">2. Installation of Chamilo LMS</span></h2>
|
|
|
|
<ul>
|
|
|
|
<li><a href="http://www.chamilo.org/download">Download Chamilo LMS</a></li>
|
|
|
|
<li>Unzip it</li>
|
|
|
|
<li>Copy the Chamilo directory in your Apache web directory. This can be
|
|
<span style="font-weight: bold;">C:\xampp\htdocs\</span> on a Windows server or <span style="font-weight: bold;">/var/www/html/</span> on a Linux server</li>
|
|
|
|
<li>Open your web browser (Internet Explorer, Firefox...) and type
|
|
<span style="font-weight: bold;">http://localhost/chamilo/</span> if you install locally or
|
|
<span style="font-weight: bold;">http://www.domain.com/chamilo/</span> if you install remotely</li>
|
|
|
|
<li>Follow the web installation process. You can accept all default
|
|
values. Consider changing the admin password to remember it. </li>
|
|
</ul>
|
|
|
|
|
|
<br />
|
|
|
|
The following directories need to be readable, writeable and executable for everyone:
|
|
<ul>
|
|
|
|
<li>chamilo/main/inc/conf/</li>
|
|
<li>chamilo/main/upload/users/</li>
|
|
<li>chamilo/main/default_course_document/</li>
|
|
<li>chamilo/archive/</li>
|
|
<li>chamilo/courses/</li>
|
|
<li>chamilo/home/</li>
|
|
</ul>
|
|
|
|
(where 'chamilo' is the directory in which you installed Chamilo)
|
|
<p>On Linux, Mac OS X and BSD operating systems you can use the CHMOD
|
|
777 command for this (although we recommend you seek advice from an
|
|
experienced system administrator).
|
|
In Windows, you may need to check the properties of the folders (by
|
|
right-clicking on them).</p>
|
|
|
|
<p>
|
|
2.5. The following files need to be readable and writeable for the web browser,
|
|
only during the installation process:</p>
|
|
|
|
<ul>
|
|
|
|
<li>chamilo/main/inc/conf/configuration.php (if present)</li>
|
|
</ul>
|
|
|
|
|
|
<p>On Linux, Mac OS X and BSD operating systems you can use the CHMOD
|
|
666 command for this (although we recommend you seek advice from an
|
|
experienced system administrator).
|
|
In Windows, you may need to check the properties of the files and
|
|
folders (by right-clicking on them).</p>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
<b>NOTES:</b><br />
|
|
|
|
Do not modify the home_*.html files directly. Instead,
|
|
choose "Configure the homepage" in the Chamilo administration section.</p>
|
|
|
|
<p><span style="font-weight: bold;">Windows</span> : with combination packages like XAMPP, out of the box, login and password
|
|
for MySQL should probably remain empty.</p>
|
|
|
|
<p></p>
|
|
|
|

|
<h3><strong> Configuration and security after installation</strong></h3>
|
|
|
|
<ul>
|
|
|
|
<li><strong>Protect your configuration file: </strong>
|
|
make sure no one can overwrite it. You can find the config file in <em>(chamilo folder)</em>/main/inc/conf/configuration.php.
|
|
Make it read-only (windows/xwindows: right-click the file to edit the
|
|
properties. linux/bsd/macosx: use the chmod 444 command). The config
|
|
file is created by Apache so you may need to be root user to change its
|
|
permissions.</li>
|
|
|
|
<li><strong>Protect your installation folder: </strong>
|
|
if the <em>(chamilo folder)</em>/main/install
|
|
folder is still accessible, someone could install over your existing
|
|
version (you could lose your data that way). Move the folder somewhere
|
|
out of the web directories so it is not accessible, change its name, or
|
|
edit its properties so no one can read or execute it.</li>
|
|
|
|
<li><strong>For better security: </strong>
|
|
making the files world-writable will help you install, and solves many
|
|
issues for people without much admin experience. However, it's better
|
|
security to make the owner of the apache process (often called apache
|
|
or www-data) also owner of all the chamilo files and folders. Ths way,
|
|
these files need only be readable and writable by the Apache process
|
|
owner, not by the entire world.</li>
|
|
|
|
<li><strong>Configure your Chamilo installation: </strong>
|
|
in the administration section of Chamilo, you can use the Chamilo Config Settings to adjust the behavior of your installation.</li>
|
|
|
|
<li><strong>Configure Chamilo mail: </strong>
|
|
most of Chamilo uses the mail settings from the php.ini file. However,
|
|
the announcements tool uses phpMailer (another free software project)
|
|
and the settings for this tool can be adjusted in <em>(chamilo folder)</em>/main/inc/conf/mail.conf.php.</li>
|
|
</ul>
|
|
|
|
<br />
|
|
|
|
|
|
<h3>PHP configuration</h3>
|
|
|
|
|
|
To get the best of Chamilo, you need to finetune PHP settings. Consider : <br />
|
|
|
|
<ul>
|
|
|
|
<li>Editing php.ini file (on windows can be located at <span style="font-weight: bold;">C:\xampp\php\php.ini</span>, on Ubuntu Linux : <span style="font-weight: bold;">/etc/php5/apache2/php.ini</span></li>
|
|
|
|
<li>search the word "max" and increase values to optimise the server</li>
|
|
|
|
<li>you may want to end up with the following values : </li>
|
|
</ul>
|
|
|
|
|
|
|
|
<div class="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 = 64M<br />
|
|
upload_max_filesize = 100M
|
|
</div>
|
|
|
|
<p>Some users could meet problems if their PHP settings don't fit
|
|
these ones:</p>
|
|
|
|
<ul>
|
|
<li>short_open_tag = On</li>
|
|
<li>safe_mode = Off</li>
|
|
<li>magic_quotes_gpc = On</li>
|
|
<li>magic_quotes_runtime = Off</li>
|
|
</ul>
|
|
|
|
<p>
|
|
Past Chamilo versions required register_globals to be set to On. This is
|
|
no longer necessary, this can be set to Off and Chamilo will work fine.</p>
|
|
|
|
<p><strong>Note:</strong> if you are using PHP 5.3 or higher, you need to set your <em>date.timezone</em> setting to whatever your server's timezone is.
|
|
For example, if your server is in the 'America/New_York' timezone, set this in your php.ini:</p>
|
|
|
|
<div class="code">
|
|
date.timezone = 'America/New_York'
|
|
</div>
|
|
|
|
<p><strong>BSD users:</strong> these php libraries have to be included during php installation:</p>
|
|
|
|
<ul>
|
|
<li>php-mysql The mysql shared extension for php</li>
|
|
<li>php-pcre The pcre shared extension for php</li>
|
|
<li>php-session The session shared extension for php</li>
|
|
<li>php-zlib The zlib shared extension for php</li>
|
|
<li>(optional) php-ldap if you want to be able to use LDAP authentication</li>
|
|
</ul>
|
|
|
|
<p>You might also add the following php modules and packages:</p>
|
|
<ul>
|
|
<li>php-ctype</li>
|
|
<li>php-gd</li>
|
|
<li>php-iconv</li>
|
|
<li>php-json</li>
|
|
<li>php-mbstring</li>
|
|
</ul>

<h2><a name="3._Upgrade_from_a_previous_version_of"></a>3. Upgrade from a previous version of Chamilo/Dokeos</h2>
|
|
Before upgrading we <b>heavily</b> recommend you do a full backup of the previous
|
|
Chamilo/Dokeos directories and databases. If you are unsure how to achieve this
|
|
please ask your hosting provider for advice.<br />
|
|
|
|
<p></p>
|
|
|
|
|
|
<h3>3.1 Upgrading from Dokeos 1.8.x</h3>
|
|
|
|
|
|
<em>If you upgrade from Dokeos 1.8.x</em> :
|
|
<ul>
|
|
<li> check that you haven't left any customised stylesheet or image*</li>
|
|
<li> download the Chamilo 1.8.6.2 Salto install package from the <a href="http://www.chamilo.org/download">Chamilo download page</a></li>
|
|
<li> unzip the new files of Chamilo 1.8.6.2 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 <span style="font-style: italic;">Upgrade from 1.8.x</span></li>
|
|
</ul>
|
|
|
|
<br />
|
|
|
|
<font size="-1">* 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 Dokeos 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).</font>
|
|
<br />
|
|
|
|
<p></p>
|
|
|
|
<h3>3.2 Upgrading from Dokeos 1.6.x</h3>
|
|
|
|
|
|
<em>If you upgrade from a lower version of Dokeos (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/Dokeos 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 Dokeos 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 1.8.6.2 install package from the
|
|
<a href="http://www.chamilo.org/download">Chamilo download page</a></li>
|
|
<li> unzip the new files of Chamilo 1.8.6.2 in the main Chamilo/Dokeos directory. The
|
|
new directory <em>main</em> should be located directly inside your
|
|
Chamilo/Dokeos root folder</li>
|
|
<li> point your browser on your portal URL</li>
|
|
<li> choose your language and click <span style="font-style: italic;">Upgrade from 1.6.x</span> and confirm the
|
|
current directory of the old version</li>
|
|
</ul>
|
|
|
|
<br />
|
|
|
|
<em> NOTE: </em> The upgrade from 1.6.x to 1.8.x implies a revision of
|
|
the customised graphics and styles. The new version uses a complete new
|
|
set of icons and styles, which means the ones from version 1.6 cannot be
|
|
simply reused. The good news is the version 1.8.x allows you to create
|
|
your own style in a separate css folder, that you can then reuse through
|
|
all the 1.8.x versions
|
|
<br />
|
|
|
|
<p></p>
|
|
|
|
<p>
|
|
<b>WARNING:</b><br />
|
|
|
|
Do not delete the previous Chamilo/Dokeos installation directory before installing
|
|
the new one. When the update is successfully finished, you can remove
|
|
the old path.</p>
|
|
|
|
|
|
<p>
|
|
<b>NOTE:</b><br />
|
|
|
|
Do not modify the home_*.html files directly. Instead,
|
|
choose "Configure the homepage" in the Chamilo administration section.</p>
|
|
|
|
<p></p>
|
|
<h3>3.3 In both cases</h3>
|
|
|
|
The following directories need to be readable, writeable and executable for the web server:
|
|
<ul>
|
|
<li>chamilo/main/inc/conf/</li>
|
|
<li>chamilo/main/upload/users/</li>
|
|
<li>chamilo/main/default_course_document/</li>
|
|
<li>chamilo/archive/</li>
|
|
<li>chamilo/courses/</li>
|
|
<li>chamilo/home/</li>
|
|
</ul>
|
|
|
|
On Linux, Mac OS X and BSD operating systems you can quick-fix this using the
|
|
CHMOD 777 command, but if you are unsure, we recommend you seek advice for
|
|
your own OS on <a href="http://www.chamilo.org/forum">our forum</a>.
|
|
In Windows, you may need to check the properties of the folders.
|
|
<p></p>
|
|
<h3>3.4 Quick-upgrade from 1.6.x guide for Linux</h3>
|
|
|
|
|
|
The following quick-upgrade guide assumes that:
|
|
<ul>
|
|
<li>the Chamilo database username (for MySQL) is "chamilo_db_user" and your login is "chamilo_user"</li>
|
|
<li>the chamilo installation is currently in /var/www/chamilo/ and it has 777 permissions</li>
|
|
<li>your portal's URL is http://www.portalurl.com/</li>
|
|
</ul>
|
|
|
|
<br />
|
|
|
|
|
|
On the command-line, type:
|
|
<ul>
|
|
<li>cd /tmp</li>
|
|
<li>mysqldump -u chamilo_db_user -p --all-databases --result-file=/home/chamilo_user/chamilo_old.sql</li>
|
|
<li>cp -ra /var/www/chamilo /home/chamilo_user/backup_chamilo</li>
|
|
<li>mkdir /var/www/chamilo/old_version</li>
|
|
<li>mv /var/www/chamilo/* /var/www/chamilo/old_version/</li>
|
|
<li>chmod -R 0777 /var/www/chamilo/old_version/</li>
|
|
<li>wget http://www.chamilo.org/files/chamilo-1.8.6.2.tar.gz</li>
|
|
<li>tar zxvf chamilo-1.8.6.2.tar.gz</li>
|
|
<li>sudo cp -ra chamilo-1.8.6.2/* /var/www/chamilo/</li>
|
|
<li>rm chamilo-1.8.6.2.tar.gz</li>
|
|
<li>sudo rm -r chamilo-1.8.6.2/</li>
|
|
</ul>
|
|
|
|
<br />
|
|
|
|
Then:
|
|
<ul>
|
|
<li>Direct your browser to http://www.portalurl.com/main/install/</li>
|
|
<li>Proceed with the installation</li>
|
|
<li>Review the directories permissions</li>
|
|
</ul>

<h2><a name="6._LDAP"></a>6. LDAP</h2>
|
|
|
|
<p>
|
|
<i>This part is optional, only organisations with an LDAP server will need to read this.</i><br />
|
|
|
|
An LDAP module is already provided in Chamilo, but it has to be configured to make it work.</p>
|
|
|
|
|
|
<h3><b>Compiling</b></h3>
|
|
|
|
<p>
|
|
Linux servers: It's possible that you have to recompile php with ldap support.
|
|
Newer distributions also allow downloading rpms for additional packages.</p>
|
|
|
|
|
|
<h3><b>Activating LDAP in Chamilo</b></h3>
|
|
|
|
|
|
<p>
|
|
In (chamilo folder)/main/inc/conf/configuration.php, around line 90, you see<br />
|
|
|
|
//for new login module<br />
|
|
|
|
//uncomment these to activate ldap<br />
|
|
|
|
//$extAuthSource['ldap']['login'] = "./main/auth/ldap/login.php";<br />
|
|
|
|
//$extAuthSource['ldap']['newUser'] = "./main/auth/ldap/newUser.php";<br />
|
|
|
|
<br />
|
|
|
|
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>
|
|
|
|

<h2><a name="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
|
|
|
|
<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>$config['MimetexExecutableDetectionTimeout']</b> are configured for best probability
|
|
of automatic detection of the installed on the server file <i>mimetex.cgi</i> or <i>mimetex.exe</i>.
|
|
In rare cases these options might need to be twicked, see the acccompanying comments abou
|
|
these options within the file <i>myconfig.php</i></li>
|
|
|
|
<li>3.3. Once the plugin has been activated, almost in all toolbars the corresponding button appears.
|
|
If you need to edit some toolbars, see the configuration files (php) within the directory <i>chamilo/main/inc/lib/fckeditor/toolbars/</i> .
|
|
Here is an example:
|
|
<div class="code">$config['ToolbarSets']['Normal'] = array(<br />
|
|
array('FitWindow','Bold','Image','Link','PasteWord','MP3',<b>'mimetex'</b>,'Table','Subscript','Superscript','ShowBlocks')<br />
|
|
);</div>
|
|
|
|
The item <b>'mimetex'</b> represents the button, you may add it to or remove it from any toolbar.<br /><br />
|
|
</li>
|
|
</ul>
|
|
|
|
<li>4. To install mimetex executable file, make these changes:</li>
|
|
|
|
<p>Add the corresponding cgi-bin directory to your Apache configuration could be done, in Apache 2, like this:
|
|
|
|
</p>
|
|
<div class="code">
|
|
ScriptAlias /cgi-bin/ /var/www/cgi-bin/<br />
|
|
<Directory "/var/www/cgi-bin"><br />
|
|
AllowOverride None<br />
|
|
Options ExecCGI -MultiViews +SymLinksIfOwnerMatch<br />
|
|
Order allow,deny<br />
|
|
Allow from all<br />
|
|
</Directory><br />
|
|
</div>
|
|
|
|
|
|
<p>Adding a symbolic link can be done, under Windows, by creating a
|
|
shortcut to the mimetex.exe file from the cgi-bin directory, or under
|
|
Linux by issuing the following command:
|
|
|
|
</p>
|
|
<div class="code">
|
|
<p>ln -s /var/www/chamilo/main/inc/lib/mimetex/mimetex.cgi /var/www/cgi-bin/mimetex.cgi</p>
|
|
</div>
|
|
<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>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:</li>
|
|
<div class="code">
|
|
<p>sudo chmod a+x mimetex.cgi</p>
|
|
</div>
|
|
</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.<br />
