There is a piece of code in init.d script that checks if mysql is operational. /etc/init.d/mysql 128 if ! $(mysqladmin --no-defaults --socket=“$socket” --user=UNKNOWN\_MYSQL\_USER ping &\>/dev/null) ;then 129 ping\_alive=0 130 fi It’s working fine for a check, but if you use auth\_pam\_compat plugin, trying to authenticate with UNKNOWN\_MYSQL\_USER will give non-zero return code, and, thus will fail systemd unit. The reason for that is in client parameters. --enable-cleartext-plugin option should be provided on cli. But, IMO, this behaviour should be reflected in init script. ---
