Jenkins Windows 从机离线

Question

我在 CentOS 7 服务器上有 Jenkins 2.164.3。
我有一个 Windows Server 2003 从属服务器，Java 版本为 1.8.0。
我有 3 个 linux 从机成功工作。
从站上的 Windows 服务已安装并正在运行。
Windows 从属设备使用以下启动方法进行设置“让 jenkins 控制此 Windows 从属设备作为 Windows 服务器”

这个 Jenkins 服务器是一个新服务器，它取代了旧的 jenkins 服务器（大约 3 年前来自 Turnkey linux 的 debian wheezy）。该 Windows 从属服务器用于连接到该旧服务器。要删除此从站到旧服务器的连接，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 服务器启动从站，将文件复制到 c :\jenkins 文件夹和已安装的服务。

在我的新 jenkins 服务器上，我设置了 Windows 从属服务器，当我连接时，日志包含以下内容：

Windows从机是Windows Server 2003，服务已安装并运行。

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

jenkins服务器上的错误表明该服务没有运行。在windows从机上，该服务正在运行。有什么问题以及如何解决？

谢谢。

非常老的问题，但是如果您因为收到此错误而最终来到这里，请找到该jenkins_agent.pid文件并将其删除。它应该与其余的詹金斯从属文件位于同一文件夹中。此后服务应该会再次正常启动。
