java - Jenkins中的过时转发不起作用

我正在尝试使用Launch方法连接到从属节点:“通过在主服务器上执行命令来启动从属服务器”。

这是我正在使用的启动命令:

ssh -vvvA user@host java -jar /tmp/java/slave.jar

通常，我可以像这样对主机执行SSH:

ssh -A user@host

而且，因为我的密钥可以在ssh-add的输出中看到，所以它可以工作

但是，在 Jenkins 的情况下，不知何故不使用ssh-add中存在的密钥。我无法转发ssh代理，这从粗体中的文本可以明显看出，以下错误:-

这是我得到的详细错误:

从我的 Jenkins 服务器:

root@x.x.x.x:$  echo $SSH_AUTH_SOCK
/tmp/launch-52rSLt/Listeners

我已经关注了关于stackoverflow的所有问题，并且在其中一个问题中也找到了此URL(https://help.github.com/articles/using-ssh-agent-forwarding)，但是，到目前为止，一切都还没有完成

请指导我做错了什么。

谢谢

最佳答案

请验证Jenkins主服务器有权访问ssh代理(它具有SSH_AUTH_SOCK环境变量)。

您可以在$ JENKINS_URL / systemInfo页面的“环境变量”部分下看到此内容。

如果主服务器没有看到ssh代理套接字，则无法使用它。我怀疑主机没有它，但是原因取决于您安装和运行Jenkins的精确程度以及所使用的平台。如果您需要更多帮助，请提供有关设置的更多信息。
