在centos7环境上重装mysql时运行命令  
删除:\#yum remove mariadb\*   
重装:\#yum -y install mariadb\*  
启动：\#systemctl start mariadb.service 此时数据库启动报错  
查看启动状态:\#systemctl status mariadb -l  
mariadb.service - MariaDB database server

网上查了下，有的说是权限问题，设置了/var/lib/mysql 这个目录的权限扔不起作用  
配置/etc/my.cnf 文件也不起作用  
解决办法:  
最后，我删除了/var/lib/mysql  和 /etc/my.cnf 重新安装就没有错了。  
/var/lib/mysql 这个目录重装完后是不存在任何数据的，但是启动后产生了许多文件 如:mysql.sock,如果想直到为何会这样只能查看mysql官网了
