可以使用如下三种命令登录：

mysql -uroot -p,mysql -uroot,mysql -uroot -p ‘密码‘

mysql安装完成后，默认情况下，管理员帐号root是无密码的。

为root增加密码：

[[email protected] mysql-5.1.62]# mysqladmin -u root password  ‘skyboy‘

[[email protected] mysql-5.1.62]# mysql

ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: NO)

mysql> select user,host from mysql.user;
