客户端无法连接mysql

这里的mysql版本为8.0 加密方式与之前不同，很多客户端工具无法连接。或者未开启远程访问。(还有防火墙就不说了)
解决：
修改加密规则

ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER; 

修改密码为password

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'password'; 

开启远程访问权限

GRANT ALL ON *.* TO 'root'@'%'; 

刷新权限

flush privileges; 

再进行连接基本就没什么问题了
