mysql 初始密码 设置

mysql root 密碼的設置方法 

shell> mysql -u root mysql 
mysql> SET PASSWORD FOR root@localhost=PASSWORD(\'new_password\'); 

If you know what you are doing, you can also directly manipulate the privilege tables: 

shell> mysql -u root mysql 
mysql> UPDATE user SET Password=PASSWORD(\'new_password\') 
-> WHERE user=\'root\'; 
mysql> FLUSH PRIVILEGES;
