I'm using AWS(ubuntu instance). I want to use nohup to run in the background.
I tried this code in my putty.
sudo nohup python3 manage.py runserver --settings=health.settings 0.0.0.0:80
then,
nohup: ignoring input and appending output to 'nohup.out'
this code appears and website runs well. But I press 'Ctrl + C', then nohup ends. What's wrong?
nohup prevents HUP signals -- hangups, which are sent when the controlling terminal exits -- from being conveyed to the process. It doesn't ignore SIGINT, which are what ctrl+c sends.
Start your process in the background (with & as the following command separator):
sudo nohup python3 manage.py runserver --settings=health.settings 0.0.0.0:80 &
Or redirect stdin/stdout/stderr yourself and use the bash builtin disown, which does just as good a job of preventing HUPs from propagating as nohup does:
sudo python3 manage.py runserver ... </dev/null >runserver.log 2>&1 &
disown -h
...or, much better, use a real process supervision system (Upstart, DJB daemontools, runit, launchd, systemd, or one of the many others -- best practice is to use whichever one your operating system vendor ships out-of-the-box absent a compelling contrary reason) to run your process in the background and restart it when it dies.
