重启MySQL数据库服务器提示ERROR! MySQL is not running, but lock file (/var/lock/subsys/mysql)，看了下MySQL数据库状态：
| 1 2 | # service mysql status ERROR! MySQL is not running, but lock file ( /var/lock/subsys/mysql ) exists |
接着查看了下MySQL的错误日志看到：
/usr/sbin/mysqld: unknown option ‘–safe-show-database’
所以应该是my.cnf文件中配置出错了，将这行给去掉之后重启MySQL成功：
| 1 2 3 4 5 | # service mysql restart ERROR! MySQL server PID file could not be found! Starting MySQL.. SUCCESS! # service mysql status SUCCESS! MySQL running (4040) |
配置文件my.cnf 丢失，导致mysql服务不能启动等等故障：
| 1 2 | [root@centos6 init.d] # service mysqld start Starting MySQL.. ERROR! The server quit without updating PID file ( /var/lib/mysql/centos6 .pid). |
重新拷贝正确my.cnf配置文件到/etc/目录下
| 1 2 3 4 5 6 | [root@centos6 mysql] # cp support-files/my-large.cnf /etc/my.cnf cp ：是否覆盖 "/etc/my.cnf" ？ y [root@centos6 mysql] # service mysqld start Starting MySQL.... SUCCESS! [root@centos6 mysql] # service mysqld status SUCCESS! MySQL running (50035) |
运行ok
