最近由于种种原因需要重装mysql。打开终端开始卸载

sudo apt-get remove mysql-comm

sudo apt-get auto remove

重新开始安装mysql

sudo apt-get install mysql-client-5.5

sudo apt-get install libmysql-cil-dev

执行mysql，发生如下错误

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
随即百度，但是未解决问题，忽然想到mysql-server忘记重装，继续安装mysql-server

sudo apt-get install mysql-server-5.5

安装完成

启动mysql

sudo service mysql restart

然后执行 $xxx>mysql

成功启动mysql
