navicat连接mysql出现Client does not support authentication protocol requested by server解决方案

USE mysql;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '831015';
FLUSH PRIVILEGES;

root是用户名
localhost是ip地址127.0.0.1都是特指本机，%表示任何IP都可访问
mysql_native_password是旧的密码验证机制，831015是密码，最后别忘了分号；
