How should hard drive be partitioned for Plesk installation?


Plesk for Linux OS stores user data in the /var directory, by default, so the partitioning should be set up as follows:

SWAP     ->     defer to recommendations from the OS vendor (usually RAMx2)

/boot    ->     128 MB

/        ->     system + Plesk, updates. 5-10 GB should be enough

/tmp     ->     1GB (greater than 3 GB for Plesk 11.0 and later)

/var     ->     the rest of the space (domains, mail, backups, and databases are stored there)

Note: it may vary. The /usr/local/psa/tmp/ directory as well as the /usr/local/psa/PMM/tmp/ one are used as a temporary placeholder for backups. For instance, when downloading a backup file via Plesk GUI, a temporary file with the same size is created in those locations.

Directories, that usually contain large amounts of data, include:

  • /var/www/vhosts (/srv/vhosts on SuSE) - domains content

  • /var/qmail - mail configuration/content

  • /var/lib/mysql' - MySQL databases

  • /var/lib/psa/dumps - Plesk client/domain backups

  • /var/lib/pgsql/data - PostgresQL databases

  • /var/tomcat* - Tomcat applications

  • /var/lib/mailman - Mailman lists

    The /etc/psa/psa.conf file defines other directories used by Plesk.

    On Debian and Ubuntu, Plesk files are located in /opt/psa directory.

    Currently supported operating systems can be found on the product requirements page at Release Notes for Plesk 12.0 for Linux Systems.
