Question

我最近在开发Jenkins环境中设置了一个RHEL7从属节点，它只是通过SSH运行一些特定于Unix的脚本。

在我的公司生产环境（使用不同的从属节点（Ubuntu 16.04））中，基本上已经复制了这个时间，我已经从Dev jenkins复制了从属节点配置并且正在处理日志产生的错误，但是我已经暂时停留在这个阶段，并且无法找到与我的情况相关的任何文档。

我收到以下错误：

我有双重，三重检查根目录（home / jenkins / jenkins_slave）的权限，他们很好。如果我尝试在从属节点上手动运行java -jar slave.jar，我会收到以下错误：

WARNING: Are you running slave agent from an interactive console?
If so, you are probably using it incorrectly.
See http://wiki.jenkins ci.org/display/JENKINS/Launching+slave.jar+from+from+console
<===[JENKINS REMOTING CAPACITY]===>

我只是不明白，因为权限和配置是相同的所以它必须是环保的东西？任何帮助/指导将不胜感激。

您的住宅不是/home/jenkins/jenkins_slave而是home/jenkins - 至少根据您提供的日志输出（Starting slave process: cd "/home/jenkins" [...]）。因此，您应该将奴隶的启动配置更改为/home/jenkins/jenkins_slave
