Sometimes your server hangs and you see errors. This is a simple guide to help you eliminate those errors.
Have you seen the following error:
Error: That port is already in use.
If so, this is how you would kill the server that's running.
$ lsof -i :8000
8000 is the port. So, if your using django and you run python manage.py runserver it's likely your port will be "8000"
That command will yield something like:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
python 1158 jmitch 3u IPv4 0x4ae303085ae91559 0t0 TCP localhost:irdmi (LISTEN)
Except under "jmitch" it would have your username. Do you see the value under "PID" this is the number you need. Now you just kill that process.
$ kill -9 1158
Let's do that one more time:
$ lsof -i :8000
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
python 4894 jmitch 3u IPv4 0x4ae3030864c1dd41 0t0 TCP localhost:irdmi (LISTEN)
$ kill -9 4894
And that's it. You can kill this server without an error running.
Alternatively we can use the fg command in linux, which brings our processes to the foreground, and than press ctrl + c to quit the server.
For more help on fg use :
$ help fg
Please share questions/comments! (We're always looking for better ways to improve).
