• The Plesk PSA database was also removed as a consequence

Cause

Plesk was removed by dependencies.

Resolution

1. Login to the server via SSH

2. Restore the latest valid psa database dump from /var/lib/psa/dumps/:

   Note: A dump with name mysql.plesk.core.prerm is created before the removal of Plesk

   # zcat /var/lib/psa/dumps/mysql.plesk.core.prerm.xxxxxxx.dump.gz | MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -uadmin

3. Download Plesk Installer:

   # wget https://autoinstall.plesk.com/plesk-installer

4. Add execution permissions to script:

   # chmod +x plesk-installer

5. Launch Plesk Installer with the command below and follow the on-screen instructions selecting all default options:

   # ./plesk-installer

6. Scan and repair installation:

   # plesk repair installation
