环境： mysql55 redhat5.7

首先阐明，去年用arch时玩mariadb，用的很顺风顺水.... 但是今年在arch下我的mariadb也一直没安装成功，情况基本跟现在一样...之前没有填坑，现在必须弥补了...

安装完后，启动失败...但并不清楚问题出在哪儿....试了下mysqld -urooot登录，发现是这个错误：

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mys ql.sock' (2)

这个sock文件是不存在的...

我尝试安全启动，但是还是错误，下面是找到的错误日志(/var/lib/mysql/test.err)：

其它地方的日志基本就没有有用的信息了(可能是我没找全)

看了错误日志，发现错误，按照提示执行命令，但是又出现这个结果...
