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).


config-dist.php

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.

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:

$CFG->includeuserpasswordsinbackup = true;

Note regarding restoring Moodle 2.5 backups to sites with old PHP versions:

Because bcrypt is not supported in PHP versions below 5.3.7, course backups made using the $CFG->includeuserpasswordsinbackup setting on a site using PHP version 5.3.7+ that are subsequently restored to a site with PHP version < 5.3.7 will require a password reset.

Changing default block layout for new courses

See Block layout.

Adding extra theme directory location

It is possible to add an extra themes directory stored outside of $CFG->dirroot. This local directory does not have to be accessible from internet. 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 extra themes in a subdirectory called 'my_moodle_themes', your config.php might look like this:

$CFG->wwwroot   = 'http://my.moodle.site.edu';
$CFG->dirroot   = '/var/www/my.moodle.site.edu/public_html';
$CFG->themedir  = $CFG->dirroot . '/my_moodle_themes';

Disabling update notifications

See Notifications.

Enabling debugging

See Debugging.

Forcing the value of admin settings

As explained in config-dist.php, it is possible to specify normal admin settings here, the point is that they can not be changed through the standard admin settings pages any more. Just set the value in config.php like:

$CFG->showuseridentity = 'email,idnumber,username';
