+Server identifier
+-----------------
 
+When your Nextcloud instance is using several PHP servers, each one must have an unique identifier.
+
+serverid
+^^^^^^^^
+
+This identifier must be an integer between 0 and 1023.
+For a single server of if each server have it's own ``config.php``, server ID can be configured in the usual way in ``config.php``
+
+::
+
+  'serverid' => 123,
+
+
+Otherwise, you can use a environment variable ``NC_serverid`` to configure it. It must be configured for your webserver and for CLI.
+
+In Apache server, you can use the following directive to add it:
+
+::
+
+  SetEnv NC_serverid 123
+
+For CLI, we recommend to use an alias. Example for Bash:
+
+::
+
+  alias nocc="sudo -u www-data NC_serverid=123 /path/to/nextcloud/occ"
