Configuration file

De MoodleDocs
Salta a:navegació, cerca

The name for Moodle's configuration file is config.php. The file is located in the moodle directory. It is not included in the Moodle download packages and is created by the installation process from the template file config-dist.php (which is included in Moodle packages).


Although the installation process creates the config.php file for you, there may be times when you want to do this yourself. A sample config file, called config-dist.php, is shipped with Moodle.

To get started simply copy config-dist.php to config.php, then edit config.php with you favourite editor. The file is very well commented. The important options (which you must supply) are all nearer the top. Other less common options are further down.

Setting $CFG->wwwroot correctly

This setting must be a fixed URL (a string constant) that points to your site. Do not try to set this with any PHP code that can generate a variable URL. This is not supported, can cause strange problems and will stop command line scripts working completely. If your site is accessed from different IP addresses this should be done with a split DNS, see Masquerading

Enabling password salting

See Password salting.

Including passwords in backups

Hashed user passwords are no longer saved in backup files containing user data in Moodle 1.8.11 and 1.9.7 onwards.

If you really need passwords to be saved (in the rare case of restoring a backup with user data to a different site), the following line may be added to config.php:


Changing default block layout for new courses

See Block layout.

Changing default theme directory location

The location of theme directories may be altered, using the variables $CFG->themewww and $CFG->themedir. Themes placed in the directory specified by these variables will then be available for selection using the theme selector.

For example, should you wish to place themes in a subdirectory called 'my_moodle_themes', your config.php might look like this:

$CFG->wwwroot   = '';
$CFG->dirroot   = '/var/www/';
$CFG->themewww  = $CFG->wwwroot . '/my_moodle_themes';
$CFG->themedir  = $CFG->dirroot . '/my_moodle_themes';
