# Maintenance Mode Configuration

You must put your ownCloud server into maintenance mode before performing upgrades, and for performing troubleshooting and maintenance. Please see Using the occ Command to learn how to put your server into the various maintenance modes (`maintenance:mode, maintenance:singleuser`, and `maintenance:repair`) with the `occ` command.

`maintenance:mode` locks the sessions of logged-in users and prevents new logins. This is the mode to use for upgrades. You must run `occ` as the HTTP user, like this example on Ubuntu Linux:

    $ sudo -u www-data php occ maintenance:mode --on

You may also put your server into this mode by editing `config/config.php`. Change `"maintenance" => false` to `"maintenance" => true`:

    <?php

     "maintenance" => true,

Then change it back to `false` when you are finished.
