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; (责任编辑:IT) |
