Thank you for choosing MySQL!

Remember to check the platform specific part of the reference manual

for hints about installing MySQL on your platform.
Also have a look at the files in the Docs directory.

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：

[iyunv@www mysql-5.1.62]# mysqladmin -u root password  'skyboy'
[iyunv@www mysql-5.1.62]# mysql
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
