I am using vagrant along with Virtualbox, so I can't runserver on the default port and address or it won't work.
Django says:
(...) to listen on all public IPs (useful if you want to show off your work on
other computers), use:
python manage.py runserver 0.0.0.0:8000
Then I tried to access the server via http://127.0.0.1:8888/ but it says Unable to connect. Any guess how to run the server correctly?
I have followed the gettingstartedwithdjango vidoes and this http://127.0.0.1:8888/ worked for the author.
For people who are just looking where to configure the IP, it is run like so (as seen in the OP) -
python manage.py runserver 0.0.0.0:8000
If you are accessing it over your local network you will also need to update settings.py with the IP of your host, as well as specifying localhost. Your local IP can be gotten on Windows by running ipconfig in the command prompt, or ip addr show in the terminal on Ubuntu.
ALLOWED_HOSTS = ['192.168.1.XXX', 'localhost']
You have to run with root privileges. If you run with sudoyou will succeed.
UPDATE 1
The previous information is irrelevant with the topic.
In vagrant you have to forward your port to a local port. Please have a look at this.
UPDATE 2
This page explained how to install and configure django in a vagrant box.

I am running python manage.py runserver from a machine A
when I am trying to check in machine B. The url I typed is http://A:8000/ .
I am getting an error like The system returned: (111) Connection refused
You can run it for machines in your network by
./manage.py runserver 0.0.0.0:8000
And than you will be able to reach you server from any machine in your network.
Just type on other machine in browser http://192.168.0.1:8000 where 192.168.0.1 is IP of you server... and it ready to go....
or in you case:
On machine A in command line ./manage.py runserver 0.0.0.0:8000
Than try in machine B in browser type http://A:8000

You need to tell manage.py the local ip address and the port to bind to. Something like python manage.py runserver 192.168.23.12:8000. Then use that same ip and port from the other machine. You can read more about it here in the documentation.
I was struggling with the same problem and found one solution. I guess it can help you. when you run python manage.py runserver, it will take 127.0.0.1 as default ip address and 8000. 127.0.0.0 is the same as localhost which can be accessed locally. to access it from cross origin you need to run it on your system ip or 0.0.0.0. 0.0.0.0 can be accessed from any origin in the network.
for port number, you need to set inbound and outbound policy of your system if you want to use your own port number not the default one.
To do this you need to run server with command python manage.py runserver 0.0.0.0:<your port> as mentioned above
or, set a default ip and port in your python environment. For this see my answer on
django change default runserver port

Just in case any Windows users are having trouble, I thought I'd add my own experience. When running python manage.py runserver 0.0.0.0:8000, I could view urls using localhost:8000, but not my ip address 192.168.1.3:8000.
I ended up disabling ipv6 on my wireless adapter, and running ipconfig /renew. After this everything worked as expected.
in flask using flask.ext.script, you can do it like this:
python manage.py runserver -h 127.0.0.1 -p 8000
For people who are using CentOS7, In order to allow access to port 8000, you need to modify firewall rules in a new SSH connection:
sudo firewall-cmd --zone=public --permanent --add-port=8000/tcp
sudo firewall-cmd --reload
I had the same problem and here was my way to solve it:
First, You must know your IP address.
On my Windows PC, in the cmd windows i run ipconfig and select my IP V4 address. In my case 192.168.0.13
Second as mention above: runserver 192.168.0.13:8000
It worked for me.
The error i did to get the message was the use of the gateway address not my PC address.
First, change your directory:
cd your_project name
Then run:
python manage.py runserver
Ok just came across this post this is a little off topic but hopefully explains a few things, The IP 127.0.0.1 points to your network card so any traffic that you cause to go to that IP address will not leave your computer.
For example modern network cards in laptops for example will not even give you that IP if you are not connected to a wifi or cabled network so you'll need to be connected at least to activate the card.
If you need to run multiple servers on the same machine but want to access them with a domain then you have a couple of options
edit your computers host file to define the domain and what IP it goes to
use a DNS Alias I set up using a cname record years ago *.local.irishado.com will point to 127.0.0.1
so for example these three domains will point to your local machine
http://site1.local.irishado.com
http://site2.local.irishado.com
http://site3.local.irishado.com
will all point to your local machine then in python projects you will need to edit the projects setting file ALLOWED_HOSTS property to hold the domain it will accept
ALLOWED_HOSTS = ['site1.local.irishado.com']

I followed the instructions here to run Django using the built-in webserver and was able to successfully run it using python manage.py runserver. If I access 127.0.0.1:port locally from the webserver, I get the Django page indicating it worked.
I realize the Django webserver is not a production server, but it's important for me for testing purposes to be able to access it from the outside world -- i.e. not from a web browser on the server, but from a different computer.
I tried:
http://mywebserver:port_django_runs_on
but it did not work. I also tried using the IP instead (based on ifconfig) to access:
http://myipaddress:port_django_runs_on
which did not work either.
The web server is running so it must be accessible from the outside, I'm just not sure how. I am running Linux with Apache, though I have not configured Django with Apache.
Any ideas on how to do this?
You have to run the development server such that it listens on the interface to your network.
E.g.
python manage.py runserver 0.0.0.0:8000
listens on every interface on port 8000.
It doesn't matter whether you access the webserver with the IP or the hostname. I guess you are still in your own LAN.
If you really want to access the server from outside, you also have to configure your router to forward port e.g. 8000 to your server.
Check your firewall on your server whether incoming connections to the port in use are allowed!
Assuming you can access your Apache server from the outside successfully, you can also try this:
Stop the Apache server, so that port 80 is free.
Start the development server with sudo python manage.py runserver 0.0.0.0:80
I had to add this line to settings.py in order to make it work (otherwise it showed an error when accessed from another computer)
ALLOWED_HOSTS = ['*']
then ran the server with:
python manage.py runserver 0.0.0.0:9595
Also ensure that the firewall allows connections to that port
Pick one or more from:
Your application isn't successfully listening on the intended IP:PORT
Because you haven't configured it successfully
Because the user doesn't have permission to
Your application is listening successfully on the intended IP:PORT, but clients can't reach it because
The server local iptables prevents it.
A firewall prevents it.
So, you can check that your application is listening successfully by running lsof -i as root on the machine and look for a python entry with the corresponding port you've specified.
Non-root users generally cannot bind to ports < 1024.
You'll need to look at iptables -nvL to see if there's a rule that would prevent access to the ip:port that you are trying to bind your application to.
If there is an upstream firewall and you don't know much about it, you'll need to talk to your network administrators.
just do this:
python manage.py runserver 0:8000
by the above command you are actually binding it to the external IP address.
so now when you access your IP address with the port number, you will be able to access it in the browser without any problem.
just type in the following in the browser address bar:
<your ip address>:8000
eg:
192.168.1.130:8000
you may have to edit the settings.py
add the following in the settings.py in the last line:
ALLOWED_HOSTS = ['*']
hope this will help...
For AWS users.
I had to use the following steps to get there.
1) Ensure that pip and django are installed at the sudo level
sudo apt-get install python-pip
sudo pip install django
2) Ensure that security group in-bound rules includ http on port 80 for 0.0.0.0/0
configured through AWS console
3) Add Public IP and DNS to ALLOWED_HOSTS
ALLOWED_HOSTS is a list object that you can find in settings.py
ALLOWED_HOSTS = ["75.254.65.19","ec2-54-528-27-21.compute-1.amazonaws.com"]
4) Launch development server with sudo on port 80
sudo python manage.py runserver 0:80
Site now available at either of the following (no need for :80 as that is default for http):
[Public DNS] i.e. ec2-54-528-27-21.compute-1.amazonaws.com
[Public IP] i.e 75.254.65.19
I'm going to add this here:
sudo python manage.py runserver 80
Go to your phone or computer and enter your computers internal IP (e.g 192.168.0.12) into the browser.
At this point you should be connected to the Django server.
This should also work without sudo:
python manage.py runserver 0.0.0.0:8000
UPDATED 2020
TRY THIS WAY
python manage.py runserver yourIp:8000
ALLOWED_HOSTS = ["*"]
You need just to allow any hosts :
settings.py :
ALLOWED_HOST = ['*']
Run your server :
python3 manage.py runserver 0.0.0.0:8000
If you want to connect android app just add internet permission in AndroidManifest
It's work for me ;)
open terminal
type : ifconfig
check results of ifconfig command
use the inet IP .. should look like this.. 192.168.1.121 or similar 192.168.x.x.
now runserver like you normally do but this time specify the inet IP
python3 manage.py runserver 192.168.x.x:8000 (replace the x with your inet)
also
on settings.py
ALLOWED_HOSTS = ['*']

If you are using Docker you need to make sure ports are exposed as well
Locally I can access the python project using 127.0.0.1:8000.
I want to access it via LAN as well. I've done some research how to figure it out and I've followed these steps:
in the settings.py file I did ALLOWED_HOSTS=[192.168.1.11:8000], that's my computer's LAN IP address.
Then in the terminal I've done python manage.py runserver 192.168.1.11:8000, it didn't work and I've tried to replace the IP address with 0.0.0.0:8000 but the same issue occured.
With DEBUG=True I get the following error message:
Invalid HTTP_HOST header:'<my_ip_adress>'.
You may need to add '<my_ip_adress>' to ALLOWED_HOSTS,
and I've already done this...
You need to configure your ALLOWED_HOSTS variable correct:
It must be a list of strings, representing the allowed hosts without defining the ports.
It must include every and any possible host that you want to allow.
So you need to:
ALLOWED_HOSTS = [
'192.168.1.11',
'127.0.0.1', # This is the one you need to allow in your case
]
Finally as #cezar points out, you need to run the server at 0.0.0.0:8000 in order to "broadcast" it on your LAN:
python manage.py runserver 0.0.0.0:8000
Good luck :)
If you just want to make it accessible for test purposes in the Local Area Network, then run:
python manage.py runserver 0.0.0.0:8000
In your settings.py an empty list for allowed hosts should be enough:
ALLOWED_HOSTS = []
In your terminal/command promt type
ifconfig #for linux
ipconfig #for windows
You will get the information about the network connection and you will find your IP. Take that IP and run as
python manage.py runserver <your-ip>
in django settings.py
ALLOWED_HOSTS = ['*']
Now you can connect this server throughout any device connected to the same network.
This works for me on Ubuntu 19.10
sudo ufw allow from 192.168.1.0/24 to any port 8000 proto tcp
I've also have to enable packet forwarding in /etc/sysctl.conf and delete the # prepended to net.ipv4.ip_forward=1.
Finally, I've cleared the browser cache.
Previously I was on Mint 19.03 and I only had to add the ufw rule.
