使用Navicat链接MySql出现上述错误,有两种情况两种解决方式;

前提是数据库服务启动~

1、在Navicat中新建连接时报错!意味着连接不能建立,直接报上述错误。

解决方法:

已解决!!client does not support authentication protocol requested by server consider upgrading mysql ~

此时不管能不能连接上本地数据库,起码可以在Navicat中建立新的连接。

2、注意安装MySql时我的用户名默认为root密码为root,以下,用户名错误!

已解决!!client does not support authentication protocol requested by server consider upgrading mysql ~

连接测试之后报错错误同上:

已解决!!client does not support authentication protocol requested by server consider upgrading mysql ~

解决办法:

输入正确的用户名和密码,也就是你在Dos安装MySql时的哦那个户名和密码

已解决!!client does not support authentication protocol requested by server consider upgrading mysql ~

成功!

已解决!!client does not support authentication protocol requested by server consider upgrading mysql ~
