SQLyog连接MYSQL时报错 Client does not support authentication protocol requested by server； consider upgra

之前安装MYSQL8.0的时候安装的是绿色版，在cmd中配置完所有参数之后，在连接SQLyog的时候却报出了以下错误

翻译一下大致的意思为：客户端不支持服务器请求的身份验证协议；考虑升级MYSQL客户端

这是因为MYSQL8.0之后更换了加密规则为caching_sha2_password,8.0之前则为mysql_native_password，用语句alter user ‘root’@‘localhost’ identified by ‘xxxxx’;来修改密码会使用8.0默认的caching_sha2_password规则来加密，而SQLyog中找不到新的身份验证插件，加载身份验证插件错误，因此产生以上报错。

解决方法

使用mysql_native_password规则重新设置密码，指令如下

use mysql;#更改密码
alter user 'root'@'localhost' identified with mysql_native_password by 'xxxxx';#刷新权限
flush privileges;

打开SQLyog重写连接即可
