MySQL修改root密码的各种方法整理

mysql -u root
mysql> SET PASSWORD FOR ‘root‘@‘localhost‘ = PASSWORD(‘newpass‘);

mysqladmin -u root password "newpass"
mysqladmin -u root password oldpass "newpass"
如果root已经设置过密码，采用第二条命令

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

net stop mysql  

mysqld-nt --skip-grant-tables     当前窗口将会停止

mysql -u root
mysql>use mysql;  
mysql>update user set password=password("new_password") where user="root";  
mysql> flush privileges;  
mysql>exit
