Workaround for error 2002 when starting MySQL

Fault description

Prompt for error 2002 at startup (HY000)

When you start the service, prompt the server quit without updating PID file.

Workaround One:

1. Because MySQL was uninstalled after reloading, view log files found that port 3306 was occupied.

2. Check which process is occupied, end the process, and restart the service.

# Lsof-i: 3306

# kill-9 4420 #4420为占用3306端口的进程号

# service Mysqld Start
