Don’t Panic if you get this error when you start, restart or stop your mysql engine.
I get error like this "/etc/init.d/mysql: /usr/local/bin/hostname: not found
/etc/init.d/mysql: /usr/local/bin/hostname: not found
ERROR! MySQL manager or server PID file could not be found!"
when i restart the mysql, yes..dont panic,
solved:
# ps -ef |grep mysql|awk '{print $2}'|xargs kill -9
