Local Django website won't load in browser

Question

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:

I built a Django/CentOS-6.3 environment

Answer 1

Check your iptables, and stop it. Ubuntu commonly does not open the iptables when it starts.

Answer 2

the host's "127.0.0.1" is not the same as the guest's "127.0.0.1". Per default the command

python manage.py runserver

listens only to the guest's localhost. You should be able to test it from within the vm (use "vagrant ssh" to login) and run

curl -I http://127.0.0.1:8000/

The host as a different IP. To access the development server from the host you have to start it without ip restriction:

python manage.py runserver 0.0.0.0:8000

Yes:

python manage.py runserver [::]:8000

should be the same. But that's IPv6 syntax AFAIK. Are you sure that the "manage.py runserver" command supports IPv6 by default? I've never used ipv6 addresses w/ django, but looking at the source (https://github.com/django/django/blob/master/django/core/management/commands/runserver.py) there seams to be a flag that the default to False ("--ipv6"). Perhaps that's the "real" problem?

If your network is configured correctly and your django application with

python manage.py runserver 0.0.0.0:8000

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.

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.

if

ps -ae | grep firewall

returns something like

602 ? 00:00:00 firewalld

your system is running firewalld, not iptables. They do not run together.

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 --reload

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

For a similar problem,

This command worked like a charm for me

python manage.py runserver [::]:8001
