mysql无法启动ERROR! MySQL is running but PID file could not be found ?

第一种方法：可能是硬盘满了，清理下垃圾文件。

第二种：

查看下数据库运行状态

/etc/init.d/mysql status
提示
ERROR! MySQL is running but PID file could not be found
先打印MYSQL进程
ps aux | grep mysql
然后KILL进程
kill -9 pid1 pid2 …
再启动MYSQL
/etc/init.d/mysql start
再检查mysql运行状态
/etc/init.d/mysql status

提示成功

第三种：是修改过my.cnf配置出错引起执行命令：vi /etc/my.cnf 修改内容：

# The MySQL server
　　　 [mysqld]
　　　 port　　　= 3306
　　　socket　 = /var/lib/mysql/mysql.sock

在执行第二种命令，OK
