1.2配置免密登录
配置openclaw到其它节点的免密登录，在openclaw服务器上操作，以10.9.254.51为例，其它节点相同。

2.使用openclaw自动化安装
确保openclaw能够访问互联网
2.1查找网络上关于xenon部署相关文档
本实验已我个人博客为例
https://blog.csdn.net/bingyan0371/article/details/159086908?spm=1001.2014.3001.5501
2.2编辑提示词
https://blog.csdn.net/bingyan0371/article/details/159086908?spm=1001.2014.3001.5501
把这篇文章精读一下，然后深入理解核心内容，总结一下目前你自己的能力，是否能登录到局域网10.9.254.51、10.9.254.52、10.9.254.53三个主机，已配置免密登录。先回答我是否能进行安装部署，再让我决定要不要进行安装部署。
2.3聊天窗口执行
帮忙配置下三个节点ssh免密互访，如果满足mysql集群安装部署条件，进行安装部署。部署完成后给我信息。
使用方案A，允许在本机编译后上传，并验证xenon高可用效果，最终给我反馈结果。
帮忙调试下Raft配置，使集群处于完全健康状态，并最终反馈结果。
3.手动验证集群
3.1查看集群状态
|-------------------------------------------------------------------------------------------------------------------------------|
| [root@poc ~]# echo '/etc/xenon.json' > /usr/local/bin/config.path [root@poc ~]# /usr/local/bin/xenoncli cluster status |
3.2查看Raft状态
|-------------------------------------------------------------------------------------------------------|
| [root@poc ~]# /usr/local/bin/xenoncli raft status |
| {"state":"FOLLOWER","leader":"","nodes":["10.9.254.51:8801","10.9.254.52:8801","10.9.254.53:8801"]} |
4.经验总结
本次安装全部由openclaw自主安装，中途确认建议3次。共用时1小时。大部分时间浪费在了网络无法下载软件包上。如果提前将使用软件包上传到openclaw上，安装用时应该可以控制到20分钟内。
提示词尽量详细，比如说主机名修改成什么，使用哪个密码，这样的话会更方便管理。
