Administration via command line
Note: You are currently viewing documentation for Moodle 1.9. Up-to-date documentation for the latest stable version is available here: Administration via command line.
If you have shell access to your web server, you may find various CLI (command line interface) scripts useful during Moodle administration. All command line tools are located in
admin/cli/*directory. To avoid problems with access control, you should run them as the owner of the web server process. It is especially important for CLI installation and upgrade as they create new files in moodledata directory and the web server has to have write access to them. In Linux distributions, the user that runs the web server is usually apache or wwrun or httpd or something similar. As a root, you will probably want to execute Moodle CLI scripts like this:
$ cd /path/to/your/moodle/dir $ sudo -u apache /usr/bin/php admin/cli/somescript.php --params
Most of the scripts accept common --help (or -h) parameter to display the full usage information, for example:
$ sudo -u apache /usr/bin/php admin/cli/install.php --help
Installation via command line
Since version 2.0, Moodle can be installed from the command line. There are two modes of installation. In interactive mode, the install script asks you for all data needed to properly set up new Moodle site. In non-interactive mode, you must provide all required data as the script parameters and then the new site is installed silently. The parameters can be passed in the interactive mode, too. The provided values are then used as the default values during the interactive session.
$ sudo -u apache /usr/bin/php admin/cli/install.php --lang=cs
To switch your site into the maintenance mode via CLI, you can use
$ sudo -u apache /usr/bin/php admin/cli/maintenance.php --enable
To turn the maintenance mode off, just execute the same script with --disable parameter.
Offline modeIn some situations, you may want to switch your Moodle site into offline mode so that it is not accessible via the web but you can not stop the web server completely (typically because there are other web pages and applications running there). If a file called
climaintenance.htmlexists in the root folder of moodledata directory, Moodle will automatically display the contents of that file instead of any other page.
$ cd /var/www/sites/moodle/moodledata/ $ echo '<h1>Sorry, maintenance in progress</h1>' > climaintenance.htmlYou can prepare a nice formatted HTML page to inform your users about the server being down and keep in the moodledata directory under a name like
climaintenance.offand rename it to the
Upgrading via command line
Moodle can be upgraded from the command line. As with the installation script, there is either interactive or non-interactive mode of the upgrade. The script itself does not put the site into the maintenance mode, you have to do it on your own. Also, the script does not backup any data (if you read this page, you probably have some own scripts to backup your moodledata and the database, right?)
$ sudo -u apache /usr/bin/php admin/cli/upgrade.php --non-interactive
Upgrading via command line is a very comfortable way of Moodle upgrade if you use CVS or git checkout of the Moodle source code. See the following procedure how to upgrade your site within several seconds to the most recent version while preserving your eventual local customizations tracked in git repository:
$ cd /var/www/sites/moodle/htdocs/ $ git fetch $ sudo -u apache /usr/bin/php admin/cli/maintenance.php --enable $ git merge origin/cvshead $ sudo -u apache /usr/bin/php admin/cli/upgrade.php $ sudo -u apache /usr/bin/php admin/cli/maintenance.php --disable
Custom site defaultsDuring the install and upgrade via CLI, Moodle sets the administration variables to the default values. You can use different defaults. See MDL-17850 for details. Shortly, all you need to do is to add a file
local/defaults.phpinto your Moodle installation. The format of the file is like
<?php $defaults['pluginname']['settingname'] = 'settingvalue'; // for plugins $defaults['moodle']['settingname'] = 'settingvalue'; // for core settings
These defaults are used during install, upgrade and are also displayed as defaults at the Site administration pages.
Reset user password
If you happen to forget your admin password (or you want to set a password for any other user of your Moodle system), you can use reset_password.php script. The script sets the correctly salted password for the given user.
$ sudo -u apache /usr/bin/php admin/cli/reset_password.php
MySQL storage engine conversion
If you run your Moodle site with MySQL database backend and use the default MyISAM as the storage engine for your tables, you may want to convert them to use some more reliable engine like InnoDB (actually, you should want to switch to PostgreSQL ;-) anyway).
$ sudo -u apache /usr/bin/php admin/cli/mysql_engine.php --engine=InnoDB
Running cron via command line
In versions 1.x, you could execute admin/cron.php either from command line or via the web. Since Moodle 2.0, only admin/cli/cron.php script can be run via command line.
