这个错误通常是由于MySQL客户端版本过低而导致的。MySQL服务器使用的身份验证协议可能不受旧版本MySQL客户端的支持,因此需要升级MySQL客户端或更改MySQL服务器的身份验证协议。以下是两种解决方法:
1.升级MySQL客户端版本
可以通过下载和安装最新版本的MySQL客户端来解决此问题。请确保使用的MySQL客户端版本与MySQL服务器版本兼容。
2.更改MySQL服务器的身份验证协议
可以更改MySQL服务器的身份验证协议以与旧版本的MySQL客户端兼容。可以通过以下步骤更改MySQL服务器的身份验证协议:
1)使用root用户登录MySQL服务器。
2)运行以下命令更改身份验证插件:
```
mysql> ALTER USER 'user'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
```
其中,'user'和'password'分别是您要更改的用户名和密码。
3)刷新MySQL权限:
```
mysql> FLUSH PRIVILEGES;
```
