Context manager to eliminate daemonizing boilerplate code.
Install with pip install daemonic.
Daemonic is pretty easy to use as a context manager:
with daemonic.daemon(
pidfile='/var/run/mydaemon.pid',
stdout=open('/var/log/mydaemon.log', 'a')):
# your daemon code here
daemonic takes care of:
- Forking twice to detach from the current terminal/process
- Changing to a different working directory
- Managing user file creation permissions (
umask) - Redirecting standard input/output/error
- Creating a locked PID file
