linux下修改mysql密码: ERROR 1396 (HY000): Operation ALTER USER failed for ‘root‘@‘localhost‘

1. 问题重现

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'xxxxx';
ERROR 1396 (HY000): Operation ALTER USER failed for 'root'@'localhost'

2. 解决方法

use mysql;
select user,host from user where user='root';

 

发现 host 列的值是 ‘%’，因此将修改密码语句改为：

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'xxxxxx';
flush privileges;
