一、重新启动mysql数据库
[root@localhost ~]# service mysqld restart
Shutting down MySQL.[  OK  ]
Starting MySQL.The server quit without updating PID file (/application/mysql-5.5.32/data/localhost.localdomain.pid).[FAILED]

二、停止mysql数据库
[iyunv@localhost ~]# service mysqld stop
MySQL server PID file could not be found![FAILED]

三、解决措施：
       1. [iyunv@localhost ~]# ps -ef | grep mysql
root      5257  4319  0 20:13 pts/1    00:00:00 mysql -uroot -px xxxxxxxx
root      7535  5289  0 20:28 pts/2    00:00:00 grep mysql
如果看到上面的内容，那说明，Mysql的进程卡死了，这时用就要把这些卡死的进程都关闭
       2.[iyunv@localhost ~]# kill -9 5257
       3.[iyunv@localhost ~]# service mysqld start
          Starting MySQL.[  OK  ]
        4.[iyunv@localhost ~]# ps -ef | grep mysql
root      7556     1  0 20:28 pts/2    00:00:00 /bin/sh /application/mysql-5.5.32/bin/mysqld_safe --datadir=/application/mysql-5.5.32/data --pid-file=/application/mysql-5.5.32/data/localhost.localdomain.pid
