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

 

MySQL新版默認使用caching_sha2_password作爲身份驗證插件，而舊版是使用mysql_native_password

當連接MySQL時報錯“plugin caching_sha2_password could not be loaded”時，可換回舊版插件。

 

    操作mysql數據庫命令：

use mysql;

查看用戶名使用的身份驗證插件：

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用戶的身份驗證插件

本地連接：

alter user rootidentified with mysql_native_password by '123';

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

FLUSH PRIVILEGES;
