Answer 1

It's best to look at the log files (/usr/local/var/mysql/*.local.err) before attempting any of the more generic answers.

In my case first it complained of not being able to open the socket file ([Server] Could not open unix socket lock file /tmp/mysql.sock.lock.) and once I changed permissions, it complained of not being able to remove it! ([Server] Could not remove unix socket lock file /tmp/mysql.sock.lock errno 13.)

Removed it and run mysql.server start and DONE.
