Mysql8.0升级后，Navicat连接报错caching_sha2_password 问题

需要重新配置加密规则

 ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;
 ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password'; #更新一下用户的密码 
ALTER USER "root"@"localhost" IDENTIFIED  BY "你的新密码";  #这样修改密码也行

   FLUSH PRIVILEGES; #刷新权限
