I am following a basic django project, mainly so I can see it run on the browser, because I have another django project where it says it runs on http//127.0.0.1:8000/ but on my browser it shows errors.
I am working linode in cmd on windows laptop, I have edited my firewall on linode to allow ssh, http and https.
https://docs.djangoproject.com/en/4.0/intro/tutorial01/
this is the tutorial I am following.
This is what my code says in cmd.
This is what my browser says.
The tutorial assumes your test server is running on the same machine; 127.0.0.1 is a shorthand for it. Your server is actually running on linode, so you need two things:
expose the server interface outside, as 127.0.0.1 is only accessible internally. The command is: python manage.py runserver 0.0.0.0:8000, see this question for more details.
access it by the remote machine IP/hostname and expose server on external interface. So, in your browser, instead of 127.0.0.1:8000, use <linode_machine_IP>:8000

I'm currently running a locally hosted website, created in flask as part of a project. I wanted the server to be externally visible, so I checked the docs, and found this:
If you run the server you will notice that the server is only
accessible from your own computer, not from any other in the network.
This is the default because in debugging mode a user of the
application can execute arbitrary Python code on your computer.
If you have the debugger disabled or trust the users on your network,
you can make the server publicly available simply by adding
--host=0.0.0.0 to the command line:
$ flask run --host=0.0.0.0 This tells your operating system to listen
on all public IPs.
I assumed the same applied to python, and when started the server like this
if __name__ == "__main__":
app.debug=True
app.run(host='0.0.0.0')
When running this the terminal said Running on http://0.0.0.0:5000/, however clicking on that link just gave a "this site can't be reached" error. I tried to go the default address that it normally directed to (127.0. ...) and although this launched the site on my laptop (where flask is running) I still couldn't access the site from other devices on the same network, even when copy-pasting the url.
I also tried typing my laptops ipv4 (192.168. ...) followed by :5000 but still was unable to connect to the server.
What have I done wrong?
Run this in your terminal:
sudo ufw allow 5000
I'm developing Django server on Ubuntu OS. Since there is no browser on that machine, I can only debug the server remotely. So I just configure it with Apache and WSGI, and now I can access it through machine public IP.
Then I want to record logs in some views for debugging, if I output the log to a file, I can see it in the file, but if I want to output it to the console, I just get confused here, where is the console? since I didn't launch it with python manage.py runserver manually, currently running server process was launched by WSGI automatically. Of course, I can just stop the process launched by WSGI, and re-launch it with python manage.py runserver manually. If so, I can't access it through machine public IP.
So how can I see logs in the console in putty
Firstly, you shouldn't be developing on the server. Do that locally and debug in the usual way there.
If you're debugging production issues, you will indeed need to use the log files. But it's pretty simple to see those in the console; you can do tail -f /var/log/my_log_file.log and the console will show the log as it is being written.
You cannot output it to the console. Since the process is not called from a console, you cannot see the stdout in a console. You can only redirect the output to a file and read the file.
If at all you want the logs in the console, then you have to call the django server from console. i.e python manage.py runserver, which should only be used for development time, as this server is not good to be used in production
I only have ssh access to a server. It is ubuntu from amazon aws. I have uploaded my django project to it. When I run the command python manage.py runserver or any variants of it, the server starts.
But as you know this will not allow me to access the web application
from my browser which resides on a different network.
My question is
What would be the way that after I give my command to runserver either via django's development server or gunicorn. I may access it from the outside world by typing IP:8000 in my browser.
Secondly I would like to turn the access to IP:8000 on/off as needed. Like I may allow access for 5 minutes and then run a command to stop the access from outside world?
For accessing the django project else every where you have use the command
python manage.py runserver 0.0.0.0:8000
then You will be access it outside by giving the IP:8000
Note : the server provided by the Django is only for the development purpose only . If you want a permanent hosting you may like to use Apache or any server , where You can host your project. Hope This helps . :)
You need assign a elastic IP address (EIP) on the aws ec2 instance, and allow the inbound traffic 0.0.0.0/0 to port 8000 from its security group.
Then you should be fine to access it from every where with EIP, such as http://54.12.23.34:8000
EIP may generate cost, if you stop the ec2 instance.
You may also want to try the command:
python manage.py runserver [::]:8000
This will bind runserver to all available interfaces on your AWS VM. Please also note: runserver is really just meant for development. Running it in production is a bad idea.
You can use http://localtunnel.me/, it's very very easy but you should use it only for development purposes.
Just in case, you want to run it on 80 port then you need root permissions
sudo python manage.py runserver 0.0.0.0:80
Well, I'm trying to access a python server (for django development) in a Virtual Box VM via vagrant, but I can't connect with it in my windows browsers. I'll try to describe all the things I've done to make this work, so maybe it can help you guys.
My configurations:
I set my vagrant file to allow connections in port 8000 (guest and host)
I have disabled my windows firewall.
I have turned off the firewall on the VM
I have disabled all chrome extensions (including addblock)
I have disabled almost all apps in my windows to minimize the chances that some program could use port 8000
I have unchecked "automatically detect settings" and "use a proxy server for your lan" in the lan settings (windows internet options), then done the ip /release, ip /renew and rebooted my machine
Yes, the python server is running well on the vm
I tried the default 127.0.0.1:8000 (no success) and changed to 0.0.0.0:8000 using the command "python manage.py runserver 0.0.0.0:8000", but still ... :(
I have a nginx server in the vm running well for my php apps in port 80, and i cant access them with no problems
I use pycharm for python development and it starts my server normally in the vm either using 127.0.0.1:8000 or 0.0.0.0:8000
I think that's it, but the error persists, I can't access my python server in my ip 192.168.56.101 in port 8000, this ip is my private network on the vm that runs good with nginx.
But the result is always the same
Whenever I try access http://192.168.56.101:8000/ all my browsers (IE, Firefox, Chrome) cannot complete the request, in Chrome the error is ERR_CONNECTION_TIMED_OUT
Thanks in advance for any help !
My problem was the firewall rules. I dont really need it since its a development environment, so I delete all the rules in /etc/iptables/rules.v4 and save the file. That solve it all. Tks.
I've been tasked by my programming teacher to learn Django. However, I need to code on a command line linux box and therefore cannot access the web page from said linux box.
To test, I need to host it on the local IP of the computer rather than localhost. I’m currently running the Django development server using this command:
python manage.py runserver 0.0.0.0:8000
Firefox and Chrome can access the development server at the Linux box’s IP address, but Internet Explorer can’t.
Unfortunately (I am said teacher), I can't provide a linux host - only a linux server and a windows host to do development on.
He's actually running the web server correctly, with the command provided by Paul. But for some reason, it's only visible in Firefox/Chrome, IE just provides a generic "Webpage cannot be displayed"
But this problem can be solved by using the entire address: http:// isn't optional like it is in Chrome and Firefox.
When you run the development server, you can make it available on the local network by specifying the IP address 0.0.0.0 for it, like this:
python manage.py runserver 0.0.0.0:8000
If your Linux box’s local IP address is e.g. 192.168.1.37, you’d access the development server at:
http://192.168.1.37:8000
Setup nginx to listen on a public port and proxy all of the requests to the django runserver.
You need to specify the IP clearly in the command line like this in order to let other clients to access. You also have to enable the port 8000 in the firewall:
python manage.py runserver 192.168.1.37:8000
