mysql修改密码

2020-08-28 08:19:33

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

1. mysqld_safe --skip-grant-tables&

mysql -u root mysql

mysql> UPDATE user SET password=PASSWORD('new password') WHERE user='root';

mysql> FLUSH PRIVILEGES;

ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';
