【问题描述】：

我在 Ubuntu 12.04 上安装 mysql 服务器没有成功。这是我在删除 --purge mysql 服务器后尝试安装时看到的内容：

$ sudo apt-get install mysql-server-5.5 mysql-server

安装了一个 mysql 客户端，但是当我尝试启动它时，我得到了这个： ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

任何帮助将不胜感激。

【参考方案1】：

好吧，我没有从 StackExchange 得到任何帮助，所以我深入挖掘并自己弄清楚：首先，我按照Removing MySQL 5.5 Completely 的说明摆脱了 mysql-server 和 mysql-client。然后我像往常一样使用apt-get简单地安装了服务器和客户端。之后一切正常。
