Mysql default administrator’s username is “root”. But in the case of Parallel plesk panel , “admin” is the username. It has all administrative privileges. To login into mysql prompt, use the below command. The password is the same as admin password in Parallel plesk control panel.
The mysql password is saved in the shadow file. Plesk below 10.x version do not have encryption mechanism enabled for password file.
# cat /etc/psa/.psa.shadow
For above 10.x version, encryption is enabled
# /usr/local/psa/bin/admin –show-password
You can also use the following method to login into mysql
# mysql -u admin -p`cat /etc/psa/.psa.shadow`
