Daemonize: running a Python script as a daemon - Ronan Lopes
A daemon is a program that runs in background in your operational system. They’re usually processes that runs for an undefined amount of time executing tasks that don’t depend on the user. On a UNIX system, you may have some examples as syslogd (logging system) and sshd (handles remote connections by SSH protocol) – you can notice that both of them end with letter “d”, indicating they run as a daemon. In a previous post I showed how to implement a Bot for collecting daily points on Gokano with Mechanize and suggested as a future work to daemonize that algorithm. In that kind of application, it’s not practical to keep the console open while the script runs, once you usually want to keep it running indefinitely. You could also want to run that script on a remote server (like an Amzon EC2 machine, for example) through SSH. Once you daemonize it, you can run it and close the connection without killing the process. In python, there are many libraries to daemonize your code. In my tests, I personally liked Daemonize a little bit more. With a few lines of code you can configure your script to run on background. You can install Daemonize through …
