How should hard drive be partitioned for Plesk Linux installation?
Plesk for Linux OS stores user data in the directory
/var, by default, so the partitioning should be set up as follows:
SWAP -> Refer to the OS vendor recommendation (usually at least the amount of RAM on the server times two).
/ -> 20GB minimum, 50GB recommended. This partition is used for the OS and Plesk updates.
/tmp -> At least 3GB recommended.
/var -> the rest of the space (domains, mail, backups, and databases are stored there)
Note: it may vary. The
/usr/local/psa/tmp/ directory (for domains backups) as well as the
/usr/local/psa/PMM/tmp/ one (for full server backups) 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– 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/lib/mailman– Mailman lists
/etc/psa/psa.conf defines other directories used by Plesk.
On Debian and Ubuntu, Plesk files are located in
