mysql 启动错误-server PID file could not be found

[[email protected] var]# service mysqld stop

MySQL manager or server PID file could not be found!       [FAILED]
解决办法:
首先查看一下进程
[[email protected]irxpert-test /]# ps aux |grep mysq*
root     10274  0.0  0.0  68160  1336 ?          13:43   0:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/irxpert-test.pid
mysql    10353  0.0  1.0 344360 39464 ?        Sl   13:43   0:00 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/lib/mysql/irxpert-test.err --pid-file=/var/lib/mysql/irxpert-test.pid
root     11884  0.0  0.0  63384   760 pts/1    S+   15:44   0:00 grep mysq*
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
[[email protected] mysql]# kill 10274
[[email protected] mysql]# kill 10353
启动Mysqlok
[[email protected] mysql]# service mysql start
Starting MySQL.                                            OK  ]
