Transfer Parallels Plesk Panel Key from one server to another server

The license key can be taken from the Parallels key administrator system. If you do not have access to the key administrator system then generally, the PP license key is stored in the file /etc/psa/psa.key (for PP 8.x) or in /etc/sw/keys/keys/keyXXYYZZ (for PP 9.x and 10.x). The file can be transferred to the new server. A restart of the PP CP is required after the key’s replacement.

How to correctly uninstall DrWeb antivirus

Uninstall DrWeb from my Parallels Plesk Panel server because we do not use it.

nswer

Log in to the server under root and do the following:

Remove DrWeb antivirus packages:

# rpm -e drweb-updater drweb-common drweb-bases drweb-base drweb-daemon psa-drweb-configurator

Go to Server > Server Components (or Tools & Settings > Server Components on Plesk 10.x and newer) and update list of server components to detect that Dr.Web has been removed.

After that, run forced update of mail server configuration:

# /usr/local/psa/admin/sbin/mchk --without-spam

Remove the cron entry remaining after the uninstallation:

# rm -rf /var/spool/cron/drweb
# rm -rf /etc/cron.daily/drweb-update

Discontinue monitoring of the service by Watchdog:

/usr/local/psa/admin/bin/modules/watchdog/wd --unmonit-service=drweb
