"ERROR! Manager of pid-file quit without updating file."Solution: You already have another mysql service is runnig. You will check and kill it with these commands:
[root@localhost ~]# ps aux| grep mysql
[root@localhost ~]# kill -9 <PID>
After doing this again use a command for restart mysql service.
