root@db2:/var/log/mysql# mysql
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

Answer 1

该mysql客户来自适当命名的mysql-client包，你没有清除。

编辑：另一方面，在我的系统上，运行客户端会can't connect to local MySQL server出错。

是否ps auxwww | grep [m]ysql显示任何正在运行的进程？如果是这样，/proc/$PID对这个过程有什么说明？也许您在某个时候从源代码安装了守护程序；也许卸载程序没有设法杀死正在运行的进程..
