本地 Django 网站不会在浏览器中加载 [英] Local Django website won't load in browser
问题描述
我猜有一个非常简单的解决方案，但我搜索了每个论坛和设置指南，但无法弄清楚:
I'm guessing there's a very simple solution to this, but I searched every forum and setup guide and can't figure it out:
我在我的 local 服务器上构建了一个 Django/CentOS-6.3 环境(使用 VirtualBox 和 Vagrant).当我使用 'python manage.py runserver [::]:8000' 在 vagrant 终端中启动我的服务器时，它启动时没有错误.
I built a Django/CentOS-6.3 environment on my local server (using VirtualBox and Vagrant). When I startup my server in the vagrant terminal with 'python manage.py runserver [::]:8000' it starts up with no errors.

Django version 1.5.1, using settings 'mysitename.settings'
Development server is running at http://[::]:8000/
Quit the server with CONTROL-C.
但是，当我尝试在浏览器中导航到http://127.0.0.1:8001"时(我在 Vagrantfile 中设置了从端口 8000 到端口 8001 的端口转发)，浏览器只挂起 5 分钟直到超时，然后它返回消息:
However, when I try to navigate to 'http://127.0.0.1:8001' in my browser (I set up port forwarding from port 8000 to port 8001 in my Vagrantfile), the browser just hangs for 5 minutes until it times out, then it returns the message:
> The connection was reset
> The connection to the server was reset while the page was loading.
> ...
这与我在关闭本地服务器后从浏览器收到的消息完全相同.我的计算机显然将此识别为转发端口，因为我尝试的任何其他端口(例如 8000)都会立即返回一个错误，指出它无法与位于 127.0.0.1:8000 的服务器建立连接.
This is the exact same message I get from the browser even after I shut down my local server. My computer obviously recognizes this as a forwarded port, because any other port I try (such as 8000) instantly returns an error saying that it can't establish a connection to the server at 127.0.0.1:8000.
关于服务器文件，我过去用 Django/Ubuntu 做过很多类似的设置，从来没有遇到过任何问题，但是 Django/CentOS 一定有一些不同的东西导致了这种情况的发生(或者也许我在我的一个服务器文件中犯了一个错误).我已按照指南设置 Django &CentOS 上的 PostgreSQL 也是如此，但无济于事.我将在下面评论我创建/编辑的一些文件.
With regard to the server files, I have done many similar setups with Django/Ubuntu in the past and have never had any issues, but there must be something different about Django/CentOS that is causing this to happen (or maybe I made a mistake someone in one of my server files). I have followed guides for setting up Django & PostgreSQL on CentOS, too, but to no avail. I'll comment some of the files I have created/edited below.
如果有人有解决方案，甚至有关于从哪里开始查找错误的建议，我将不胜感激.
If anyone has a solution, or even has advice on where to start looking for errors, I would very much appreciate it.
推荐答案
如果您的网络配置正确并且您的 django 应用程序与
If your network is configured correctly and your django application with
python manage.py runserver 0.0.0.0:8000
python manage.py runserver 0.0.0.0:8000
您仍然无法从 VM 主机访问您的 django 应用程序，几乎可以肯定是防火墙问题.如果您正在运行 iptables，则上述解决方案很好.
and you still can't access your django app from the VM host there is almost certainly a firewall issue. The solution above is good if you are running iptables.
我在一台 Windows 7 主机的虚拟机虚拟机上部署了 CentOS 7.我不知道这个发行版使用firewalld，而不是iptables来控制访问.
I deployed CentOS 7 on a virtualbox VM from a Windows 7 host. I didn't know that this distribution uses firewalld, not iptables to control access.
如果
ps -ae |grep 防火墙
ps -ae | grep firewall
返回类似的东西
602 ?00:00:00 防火墙d
602 ? 00:00:00 firewalld
您的系统运行的是 firewalld，而不是 iptables.它们不会一起运行.
your system is running firewalld, not iptables. They do not run together.
要更正您的 VM，以便您可以从主机访问您的 django 站点，请使用以下命令:
To correct you VM so you can access your django site from the host use the commands:
firewall-cmd --zone=public --add-port=8000/tcp --permanent
firewall-cmd --zone=public --add-port=8000/tcp --permanent
firewall-cmd --reload
firewall-cmd --reload

Many thanks to pablo v for pointing this out in the post "Access django server on virtual Machine".
