推荐答案

这里的问题很简单，如果你在你的主机上做 curl http://127.0.0.1:8080 ，你应该收到一条消息，说明:

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 jenkins 具有不允许任何连接的匿名权限.

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

要解决此问题，您必须进行两项更改:

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

1. 将 Jenkins 用户添加到 root 组:sudo usermod -a -G root 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"

完成后，重新启动 jenkins 服务器，然后尝试为 jenkins 安装插件.

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