You might get ERROR 2002
This may mean that mysql failed to start because you have bound mysql by using bind-address in my.cnf and have since changed the ip address or if you have used a hostname of localhost instead of 127.0.0.1 when using mysql via mysql SshPortForward.
(An IP address can change if you were running mysql in a vm, cloned it, generated a new UUID which creates a new MAC address which may cause your DHCP server to issue a new IP address)
