Jenkins无法启动:无法收听端口8080

Question

我正在使用詹金斯,从昨天起它就停止了工作.我查看了Windows服务,它已被停止(不知何故).我重新启动了它,但它立即停止了.

我查看了运行服务的目录(C:\ Program Files\Jenkins)并打开了名为jenkins.out.log的日志文件.这就是它所说的

Answer 1

已修复 - 适用于将来可能遇到此问题的其他人.我使用了这篇Techrepublic文章,归结为

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

找出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,一切都很顺利(到目前为止!).

Answer 2

要在WinStone容器上启动Jenkins(与Jenkins war捆绑在一起的默认容器),请使用以下命令:

java -jar jenkins.war --ajp13Port=-1 --httpPort=9090

此外,要检查Windows中的任何应用程序是否正在使用某个端口:

netstat -ano | find "9090"

最好在Tomcat上运行Jenkins.
