Workbench和Navicat连接MySQL8.0密码问题

Workbench:

MySQL Workbench has encountered a problem
外部组件发生异常。

Navicat:

1251 - Client does not support authentication protocol requested by server; consider upgrading MySQL client 

可能出现的缘由是：mysql8 之前的版本中加密规则是mysql_native_password,而在mysql8之后,加密规则是caching_sha2_password,

解决问题方法有两种：

方法1.升级navicat驱动；

方法2.把mysql用户登录密码还原成mysql_native_password.

(root@localhost) [(none)]> alter user root@ 192.168.56.%  identified with mysql_native_password by  124345678 ;
Query OK, 0 rows affected (0.01 sec)
