MySQL修改root密码的多种方法

时间:2021-10-04 15:56:45

在 Navicat for MySQL 下面直接执行
SET PASSWORD FOR ‘root’@’localhost’ = PASSWORD(‘newpass’);

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;
