修改密码时报错，ERROR 1396 (HY000): Operation ALTER USER failed for ‘root‘@‘localhost‘

修改密码：

先登录mysql

mysql -u root -p

输入密码

mysql> use mysql;
mysql> select user,host from user;
+------------------+-----------+
| user             | host      |
+------------------+-----------+
| root             | %         |
| admin            | localhost |
| mysql.infoschema | localhost |
| mysql.session    | localhost |
| mysql.sys        | localhost |
| zhangj           | localhost |
+------------------+-----------+

注意我的root，host是’%’

你可能执行的是:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123';

改成:

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123';
