Django Server Error: port is already in use

A more simple solution just type sudo fuser -k 8000/tcp. This should kill all the processes associated with port 8000.

EDIT:

For osx users you can use sudo lsof -t -i tcp:8000 | xargs kill -9

netstat -ntlp

It will show something like this.

   Active Internet connections (only servers)

So now just close the port in which Django/python running already by killing the process associated with it.

kill -9 PID

in my case

kill -9 6599

Now run your Django app.

ps aux | grep -i manage

after that you will see all process 


ubuntu@ip-10-154-22-113:~/django-apps/projectname$ ps aux | grep -i manage
ubuntu    3439  0.0  2.3  40228 14064 pts/0    T    06:47   0:00 python manage.py runserver project name
ubuntu    3440  1.4  9.7 200996 59324 pts/0    Tl   06:47   2:52 /usr/bin/python manage.py runserver project name
ubuntu    4581  0.0  0.1   7988   892 pts/0    S+   10:02   0:00 grep --color=auto -i manage


kill -9 process id


e.d kill -9 3440


`enter code here`after that :

python manage.py runserver project name

By default, the runserver command starts the development server on the internal IP at port 8000.

If you want to change the server’s port, pass it as a command-line argument. For instance, this command starts the server on port 8080:

python manage.py runserver 8080
