我们在Suse linux上安装了Jenkins。它运行良好，直到2天前。从昨天开始，我们面临着一个问题。 jenkins服务启动但仅持续1-2秒并再次停止。看起来服务没有在端口80上启动。我们已经在80上配置了HTTP PORT，因此文件中没有任何更改。可能的原因是什么？ 这是log contentt：

答案 0 :(得分：0)
在发布日志之后，我可以说它与我在评论中猜到的完全一样。
无法开始侦听端口（在您的情况下为80）：
java.io.IOException: Failed to start a listener: winstone.HttpListener
原因是您没有权限：
Caused by: java.net.BindException: Permission denied
这是因为最多1024个端口只能由root用户打开。您现在有两个选择：
