mysql 修改用户密码
方法1: 用SET PASSWORD命令
MySQL -u root
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');
方法2:用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"
方法3: 用UPDATE直接编辑user表
mysql -u root mysql> use mysql; mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root'; mysql> FLUSH PRIVILEGES;
