    Connection to the database server failed: Column count of mysql.user is wrong. Expected 42, found 39. Created with MySQL 50173, now running 50556. Please use mysql_upgrade to fix this error.

Cause

The mysql.proc table has an incorrect schema (was not upgraded during MySQL upgrade).

Resolution

  1. Create databases backups:

    # cp -rp /var/lib/mysql/ /root/
    • Make sure there is enough disk space on the server
  2. Run mysql_upgrade:

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql_upgrade -uadmin
  3. Make sure that mysql.proc has been upgraded and has 20 columns:

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -u admin mysql -Nse "desc proc" | wc -l
    20
  4. Continue Plesk upgrade:

    # plesk installer
