Plugin caching_sha2_password could not be loaded: The specifiedmodule could not be found.

 

MySQL新版默认使用caching_sha2_password作为身份验证插件，而旧版是使用mysql_native_password

当连接MySQL时报错“plugin caching_sha2_password could not be loaded”时，可换回旧版插件。

 

    操作mysql数据库命令：

use mysql;

查看用户名使用的身份验证插件：

mysql> select Host,User,plugin from mysql.user;

 

mysql>  select Host,User,plugin from mysql.user;
+-----------+------------------+-----------------------+
| Host      | User             | plugin                |
+-----------+------------------+-----------------------+
| %         | bg   | caching_sha2_password |
| %         | rot             | mysql_native_password |
| localhost | deaint | caching_sha2_password |
| localhost | mema | caching_sha2_password |
| localhost | msion    | caching_sha2_password |
| localhost | mys        | caching_sha2_password |
+-----------+------------------+-----------------------+
6 rows in set (0.00 sec)

    修改root用户的身份验证插件

本地连接：

alter user rootidentified with mysql_native_password by '123';

alter user root@localhost identified with mysql_native_password by '123';

FLUSH PRIVILEGES;
