jenkins - Jenkins无法启动:无法在端口8080上监听

Question

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，但之后它立即停止了。

我查看了从(C:\ Program Files \ Jenkins)运行服务的目录，并在其中打开了名为jenkins.out.log的日志文件。这就是它的意思

Answer 1

已修复-适用于将来可能会遇到此问题的其他任何人。我用了这个Techrepublic article，归结为

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!)。
