新安装的一台Centos服务器，安装完lamp后，重启了一下系统，发现mysql启动不了并报如下的错误：
| /etc/init.d/mysqld start Starting MySQL... ERROR! The server quit without updating PID file (/var/lib/mysql/feixiag.pid). |
查看日志如下：
InnoDB: Apply batch completed 2015-03-18 17:28:05 24592 [Note] InnoDB: 128 rollback segment(s) are active. 2015-03-18 17:28:05 24592 [Note] InnoDB: Waiting for purge to start 2015-03-18 17:28:05 24592 [Note] InnoDB: 5.6.21 started; log sequence number 1600607 2015-03-18 17:28:05 24592 [Note] Server hostname (bind-address): ‘*‘; port: 3306 2015-03-18 17:28:05 24592 [Note] IPv6 is available. 2015-03-18 17:28:05 24592 [Note] - ‘::‘ resolves to ‘::‘; 2015-03-18 17:28:05 24592 [Note] Server socket created on IP: ‘::‘. 2015-03-18 17:28:05 24592 [ERROR] Fatal error: Can‘t open and lock privilege tables: Table ‘mysql.user‘ doesn‘t exist 150318 17:28:05 mysqld_safe mysqld from pid file /var/lib/mysql/feixiag.pid ended |
google,百度后，也没有找到好的方法，突然想起，我在初始化数据库的时候指定了datadir的路径为/data/mysql，而在/etc/my.cnf中的datadir没有修改指定的路径。
查看/etc/my.cnf，果然是没有更改，改为datadir=/data/mysql 后，启动成功。
注：my.conf里面的内容除需要外，其它的最好都注释掉。
