现象

安装mysql时候，执行命令 /usr/local/mysql/support-files/mysql.server start，启动mysql报错如下：

[root@localhost local]# /usr/local/mysql/support-files/mysql.server start
Starting MySQL... ERROR! The server quit without updating PID file (/usr/local/mysql/localhost.localdomain.pid).
 

原因

是因为没有权限造成的原因，检查 /etc/my.cnf权限，检查 /usr/local/mysql文件夹权限

解决方式

1.修改 /etc/my.cnf 的权限为777

        chmod 777 /etc/my.cnf

2.再次启动mysql，就成功了

        /usr/local/mysql/support-files/mysql.server start
