MySQL修改root密码

1. SET PASSWORD命令

    mysql -u root
    mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpa1s');

2. mysqladmin

    mysqladmin -u root password "newpass"

如果root已经设置过密码，采用如下方法

    mysqladmin -u root password oldpass "newpass"

3. UPDATE user表

    mysql -u root;
　　mysql> use mysql;
　　mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';
　　mysql> FLUSH PRIVILEGES;
