Jenkins master正在亚马逊实例上运行,奴隶机器在专用的Soyoustart机器上运行.工作正常,直到需要重做从设置:重新安装操作系统,安装Java,添加主设备密钥到slave authorized_keys并删除/添加主设备known_hosts中的从设备.为从属设置新凭据并在Jenkins主服务器中配置节点,但无法连接到从属服务器.

设置与现在一样,并且一直与其他从站一起工作而没有打嗝.唯一不同的是,这次新的奴隶与旧的奴隶是同一台机器.

可以从CLI从主服务器ssh到从服务器(替换文件名和从属IP与此帖子的占位符): $ ssh -i <key-file> jenkins@<slave-ip>

已设置凭据:

节点配置为:

连接到从站时的输出:
