MySQL8修改密码

MySql 从8.0开始修改密码有了变化，在user表加了字段authentication_string，修改密码前先检查authentication_string是否为空

1、如果不为空

use mysql;

将字段置为空

update user set authentication_string='' where user='root';

修改密码为123456

ALTER user 'root'@'localhost' IDENTIFIED BY '123456';

2、如果为空，直接修改

ALTER user 'root'@'localhost' IDENTIFIED BY '123456';

如果出现类似如下错误

ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
mysql> GRANT ALL PRIVILEGES ON *.* TO IDENTIFIED BY '123' WITH GRANT OPTION;

需要刷新权限

flush privileges;

然后再执行

ALTER user 'root'@'localhost' IDENTIFIED BY '123456';
