Question

我在CentOS 7服务器上安装了Jenkins 2.164.3。
我有一个Java版本为1.8.0的Windows Server 2003从服务器。
我有3个linux奴隶成功工作。
从属服务器上的Windows服务已安装并正在运行。
使用以下启动方法“让jenkins作为Windows服务器将此Windows控件控制起来”来设置Windows从属服务器

此Jenkins服务器是一台新服务器，替代了旧的jenkins服务器（大约3年前从Turnkey linux上的debian wheezy）。该Windows从站用于连接到该旧服务器。要删除此从服务器上与旧服务器的连接，我执行了以下操作： 1. sc删除
2.删除文件夹c：\ jenkins
中的文件 3.重新启动服务器
4.从新的jenkins服务器启动启动的slave，它将文件复制到c：\ jenkins文件夹并安装服务。

在新的jenkins服务器上，我设置了Windows从属服务器，连接后，日志显示以下内容：

Windows从站是Windows Server 2003，该服务已安装并正在运行。

在日志文件C：\ Jenkins \ jenkins-slave.wrapper.log中，它具有以下内容：

jenkins服务器上的错误表明服务未运行。在Windows从属计算机上，服务正在运行。有什么问题，我该如何解决？

谢谢。

Answer 1

很老的问题，但是如果您因为收到此错误而结束这里，请找到 jenkins_agent.pid 文件并将其删除。它应该与您的 jenkins slave 文件的其余部分位于同一文件夹中。之后服务应该会再次正常启动。

Answer 2

我知道这个问题很旧，您已经提出了很长的建议，但这也许会对某人有所帮助。我遇到了一个Windows从属服务器类似的问题，特别是我看到它经历了重启循环的过程，就像您以前一样：

2019-05-27 12:24:16,405 DEBUG - Checking the potentially runaway process with PID=4084
2019-05-27 12:24:16,405 DEBUG - No runaway process with PID=4084. The process has been already stopped.
2019-05-27 12:24:16,405 INFO  - Starting javaw.exe -Xrs  -jar "C:\Jenkins\slave.jar" -tcp "C:\Jenkins\port.txt"
2019-05-27 12:24:16,421 INFO  - Started process 364

为解决该问题，我检查了以下内容：

查看Windows服务是否正在运行，将其循环
除了检查C:\<path to jenkins>\jenkins-slave.wrapper.log之外，还请查看C:\<path to jenkins>\jenkins-slave.err.log
- 错误日志是我发现问题的地方，我遇到了证书unable to find valid certificate的问题
编辑C:\<path to jenkins>\jenkins-slave.xml文件并修复任何引起您麻烦的启动参数。确保检查Java路径和版本。
- 在发生证书错误的情况下，我需要在参数中添加-noCertificateCheck，以便继续前进
