MySQL修改root密码的3种方法
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;
在丢失root密码的时候,可以这样
mysqld_safe --skip-grant-tables& mysql -u root mysql mysql> UPDATE user SET password=PASSWORD("new password") WHERE user='root'; mysql> FLUSH PRIVILEGES;
