Jenkins无法启动:无法在端口8080上监听 [英] Jenkins won't start: Failed to listen on port 8080

问题描述

我正在使用Jenkins，从昨天开始它已经停止工作.我看着Windows服务，它已被停止(以某种方式).我重新启动了它，但此后它立即停止了.

I am using Jenkins and since yesterday it has stopped working. I looked at the Windows Service and it had been stopped (somehow). I restarted it but it stopped immediately after.

我从(C:\ Program Files \ Jenkins)中查看了服务正在运行的目录，并在其中打开了名为jenkins.out.log的日志文件.这就是它的意思

I have looked in the directory where the service is running from (C:\Program Files\Jenkins) and opened the log file in there called jenkins.out.log. This is what it says

推荐答案

已修复-适用于以后可能遇到此问题的其他任何人.我使用了技术文章，可以归结为

Fixed - for anyone else who might have this problem in future. I used this Techrepublic article, which boils down to

netstat -a -n -o | grep "8080"

了解如何找出哪个进程正在使用端口8080，然后在任务管理器中将其杀死，然后重新启动Jenkins，一切正常(到目前为止！).

to find out how to find out which process was using port 8080 and then killed it in Task Manager and then restarted Jenkins and all was well (so far!).
