navicat报错: Client does not support authentication protocol requested by server；

由于升级mysql版本问题 如果mysql版本高的话navicat就会报错：Client does not support authentication protocol requested by server；

解决方案：

1 登陆mysql

2切换数据库 ： use mysql;

3 重写密码：alter user ‘root’@‘localhost’ identified with mysql_native_password by ‘********’;

4 flush privileges;
