在新的ubuntu 16.04服务器上安装jenkins，运行时没有网站，日志中也没有任何内容？

詹金斯说它运行没有错误，但当我去

http://myserverip:8080 

或

在浏览器中，它显示“无法访问此网站”

在服务器上，如果执行此操作：

wget http://localhost:8080

我明白了：

Connecting to localhost (localhost)|127.0.0.1|:8080... connected.
HTTP request sent, awaiting response... 403 Forbidden
2017-10-17 02:13:42 ERROR 403: Forbidden.

我是这样开始的：

sudo systemctl start jenkins

得到：

jenkins.service - LSB: Start Jenkins at boot time
  Loaded: loaded (/etc/init.d/jenkins; bad; vendor preset: enabled)
  Active:active (exited) since Thu 2017-04-20 16:51:13 UTC; 2min 7s ago
    Docs: man:systemd-sysv-generator(8)

这显然都是正确的

sudo systemctl status jenkins

给出：

   Active: active (exited) since Tue 2017-10-17 02:01:44 CEST; 13min ago

如果我这样做

ps -ef | grep jenkins

我明白了

我只是按照指南安装的

在安装之前，我执行了通常的操作：

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

知道我为什么不能见詹金斯吗？

我刚刚发现了这个问题。 Dediserve为每台服务器都内置了一个基于web的外部FW。我刚刚在dediserve控制面板中打开了8080，它可以正常工作

我习惯了linode，它没有这样一个FW——你必须在每台服务器上安装你自己的，否则它就会暴露出来
