查看/usr/local/mysql/var下面的err文件，有这个错误

查看/etc/passwd文件，里面有mysql这个用户啊。
执行adduser mysql也说该用户已经存在了呀。

你执行dpkg -l|grep mysql看一下系统内是否存在其他mysql
或找一下是否存在其他my.cnf

执行了dpkg -l那句，没有结果出来，貌似没安装MySQL？
不过我执行mysql -uroot，告诉我
===================================
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

这到底是安装了还是没安装？

小白一个，抱歉哈，多指教~
