好不容易把低版本的mysql卸载重新安装新版本的，但Navicat连接又出现了问题。根据参考的这篇博客，完美的解决了该问题。

1、通过命令行进入解压的mysql根目录下。

2、登陆数据库

mysql -uroot -p

3、再输入root的密码：

Enter password: ******Welcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 18Server version: 8.0.11 MySQL Community Server - GPLCopyright (c) 2000, , Oracle and/or its affiliates.

Type '\c' to clear the current input statement.mysql>

4、更改加密方式：

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

5、更改密码：该例子中 123456为新密码

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

6、刷新：

mysql> FLUSH PRIVILEGES;

这步完成后我已经成功解决了问题。
