按照以下 http://bhargavamin.com/how-to-do/install-jenkins-on-amazon-linux-aws/

安装后，我能够通过浏览器打开Jenkins，但是当我选择选项"安装插件"时，它显示为无法连接到Jenkins Server"错误.

那么如何解决此问题呢?

So then how to troubleshoot this issue??

推荐答案

这里的问题非常简单，如果您在主机上执行curl http://127.0.0.1:8080，则应该收到一条消息，指出:

The problem here is pretty simple, if you do curl http://127.0.0.1:8080 on your host machine, you should get a message stating:

Authentication required
<!--
You are authenticated as: anonymous
Groups that you are in:

Permission you need to have (but didn't): hudson.model.Hudson.Administer
-->

这意味着詹金斯(Jenkins)具有匿名特权，该特权不允许任何连接.

This means that jenkins has anonymous priviledges which is not allowing any connection.

要解决此问题，您将必须进行两项更改:

To solve this issue, you will have to do two changes:

1. 将Jenkins用户添加到根组:sudo usermod -a -G root jenkins

让Jenkins通过编辑文件/etc/sysconfig/jenkins并更改JENKINS_LISTEN_ADDRESS="0.0.0.0"

Make Jenkins listen to all external IPs by editing file /etc/sysconfig/jenkins and changing the JENKINS_LISTEN_ADDRESS="0.0.0.0"

完成此操作后，重新启动jenkins服务器，然后尝试安装jenkins插件.

Once this is done, restart the jenkins server and then try to install plugins for jenkins.
