client does not support a

引用: "Client does not support authentication protocol requested by server; consider upgrading MySQL client"这个错误通常是由于MySQL客户端的身份验证协议与服务器请求的协议不兼容所导致的。

引用: MySQL 4.1及以上版本使用了基于密码哈希算法的身份验证协议，与旧版本的客户端不兼容。

引用: 当使用Navicat远程连接MySQL服务器时出现此错误，原因是使用了新的加密方式。解决方法是修改MySQL的密码方式。可以通过登录MySQL控制台，选择mysql数据库并查询该用户的身份验证插件来确认。

因此，解决此问题的方法是升级MySQL客户端或修改MySQL的密码方式。你可以尝试使用新版本的MySQL客户端来解决此问题，或者通过修改MySQL用户的身份验证插件为兼容的插件来解决。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
