詹金斯奴隶显示为离线

标签： jenkins

我从以前的同事那里继承了詹金斯。不幸的是，他这样做是在没有其他人参与的情况下完成的，因此我对Jenkins的了解无非就是编写脚本并将其扔到仪表板中。如果确实有遗漏，我会向您道歉。

这周我注意到没有几个报告。当我跳进Jenkins仪表板时，it shows that the slave is offline。我登录到安装了Jenkins从站的Windows服务器，尝试运行exe，并得到以下错误：

Unable to Run Jenkins-Slave.exe

那是我检出服务并发现Jenkins服务未运行的时候。我尝试运行它，但出现此错误：

Unable to Run Jenkins Slave Service

因为我不太了解这个问题的来龙去脉，所以我不太确定如何解决它。我尝试重新启动从服务器所在的服务器以及重新启动主服务器，但是我没有任何改变。

再次，我对此不太了解，因此不胜感激！

编辑：评论者要求提供的信息，这是我从日志中看到的信息。查看 slave.out.log ，我看到的是重复的内容：

Both error and output logs will be printed to C:\Temp\JenkinsSlave\remoting

我在 slave.err.log 中看到了这一点。这些是那里的最后一个条目。它们与位于 C：\ Temp \ JenkinsSlave \ remoting ：

的日志文件中的日志完全相同。

编辑1：因此，由于@MichaelPowers，我得以使奴隶重新联机。这是通过执行本文档How to Setup a node中的步骤4来完成的。这使奴隶重新联机，但我仍然无法运行与奴隶相关的工作。在日志中，我看到了这一点：

还有其他更新奴隶的方法吗？

最终编辑：

好消息，我想一旦能够使奴隶重新上线，我要做的就是更新插件。我去了 Manage Jenkins> Manage Plugins ，并能够更新所有需要它的插件。重新启动后，我能够毫无问题地运行与从属服务器绑定的作业。

再次感谢您的帮助！

答案 0 :(得分：0)

当您的Jenkins主服务器和从服务器不同意使用哪种协议时，会发生此错误。通常在服务器升级（版本或安全策略）并且从服务器不再讲话时发生这种情况，因为主服务器和服务器不再讲任何常见的方言。

首先要尝试的是upgrading the Jenkins slave runner（请参阅第4步）。

如果不能解决问题，另一种选择是允许母版中使用Jenkins协议的较早方言。您可以通过管理Jenkins->配置全局安全性->代理->代理协议... Picture of Agent Protocol selector in Jenkins

只需检查从站支持的协议之一，并且从站应该能够再次连接。不过，由于这些协议通常由于某种原因而被禁用，因此您可能会在Jenkins控制台中收到安全警告。
