如何重安装MYSQL

netbuddy

[root@WST root]# mysqladmin -u root password 123456
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)'
Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists!
重新安装后更改密码提示 这样,,晕了
