How to 'clear' the port when restarting django runserver

Question

Often, when restarting Django runserver, if I use the same port number, I get a \'port is already in use\' message. Subsequently, I need to increment the port number each t

Answer 1

I use pkill -If 'manage.py' (-I means interactive, -f matches more than just the process name). See How to kill all processes with a given partial name? for more info on pkill.

Answer 2

You do not want to simply increment the port number when restarting a Django server. This will result in having multiple instances of the Django server running simultaneously. A better solution is to kill the current instance and start a new instance.

To do this, you have multiple options. The easiest is

Python2: $ killall -9 python

Python3: $ killall -9 python3

If for some reason, this doesn't work, you can do

$ kill <pid> where <pid> is the process id found from a simple $ ps aux | grep python command.

Answer 3

No, he's not an idiot guys. Same thing happens to me. Apparently it's a bug with the python UUID process with continues running long after the django server is shutdown which ties the port up.

Answer 4

You must have been doing control + z .. Instead do control + c that will kill the server session... Cheers!!!

Answer 5

netstat -ntlp

You're getting that message because the server is already running (possibly in the background). Make sure to kill the process (bring it to the foreground and press ctrl-c) to stop the process.
