Jenkins在Fedora上全新安装后没有加载

Question

我刚刚在Fedora上重新安装了Jenkins，请点击此页面：https://pkg.jenkins.io/redhat-stable/

所有安装都没有任何问题。但是，当我转到http://localhost:8080时，我只会看到一个白页：

请您指出可能存在的问题吗？您可以在下面找到一些可能有用的其他信息。

谢谢！

当我执行nmap localhost时，我可以看到HTTP 8080已启动：

[root@localhost jenkins]# nmap localhost

Starting Nmap 7.60 ( https://nmap.org ) at 2018-05-11 23:59 CEST
Nmap scan report for localhost (127.0.0.1)
Host is up (0.000010s latency).
Other addresses for localhost (not scanned): ::1

PORT     STATE SERVICE
631/tcp  open  ipp
8080/tcp open  http-proxy

Nmap done: 1 IP address (1 host up) scanned in 1.62 seconds

我还可以看到jenkins服务已启动：

[root@localhost jenkins]# systemctl status jenkins.service

如果我查看我的java版本，我会得到：

[root@localhost jenkins]# java -version
openjdk version "1.8.0_162"
OpenJDK Runtime Environment (build 1.8.0_162-b12)
OpenJDK 64-Bit Server VM (build 25.162-b12, mixed mode)

当我尝试使用Curl访问它时：

[fabio@localhost ~]$ curl http://localhost:8080
[fabio@localhost ~]$
