Navicat连接不上 MySQL8.0，总是报错1251

原因是MySQL8.0版本的加密方式和MySQL5.0的不一样，连接会报错
解决：更改加密方式为mysql_native_password
ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘password’; #修改加密规则
ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘password’ PASSWORD EXPIRE NEVER; #更新一下用户的密码
FLUSH PRIVILEGES; #刷新权限
