Run Python HTTPServer in Background and Continue Script Execution

由 送分小仙女□ 提交于 2020-12-08 08:03:14
问题 I am trying to figure out how to run my overloaded customized BaseHTTPServer instance in the background after running the "".serve_forever() method. Normally when you run the method execution will hang until you execute a keyboard interrupt, but I would like it to serve requests in the background while continuing script execution. Please help! 回答1: You can start the server in a different thread: https://docs.python.org/2/library/thread.html So something like: def start_server(): # Setup stuff

How do you use python-daemon the way that it's documentation dictates?

问题 I'm trying to make a daemon in python and I've come across the python-daemon package. The interesting thing about it is that the most common way I've seen it used isn't even what the documentation, which is very sparse, tells you to do import os import grp import signal import daemon import lockfile from spam import ( initial_program_setup, do_main_program, program_cleanup, reload_program_config, ) context = daemon.DaemonContext( working_directory='/var/lib/foo', umask=0o002, pidfile=lockfile

DaemonRunner: Detecting if a daemon is already running

问题 I have a script using DaemonRunner to create a daemon process with a pid file. The problem is that if someone tried to start it without stopping the currently running process, it will silently fail. What's the best way to detect an existing process and alert the user to stop it first? Is it as easy as checking the pidfile? My code is similar to this example: #!/usr/bin/python import time from daemon import runner class App(): def __init__(self): self.stdin_path = '/dev/null' self.stdout_path

Using python, daemonizing a process

由 雨燕双飞 提交于 2019-12-21 05:41:44
问题 Okay I have looked at python-daemon, and also at various other daemon related code recipes. Are there any 'hello world' tutorials out there that can help me get started using a python based daemonized process? 回答1: The PEP 3143 contains several examples, the simplest one of which is: import daemon from spam import do_main_program with daemon.DaemonContext(): do_main_program() This seems as straightforward as it gets. If there's something that's unclear, please pose specific questions. 回答2:

Can I have some code constantly run inside Django like a daemon

由 谁都会走 提交于 2019-12-20 10:46:16
问题 I'm using mod_wsgi to serve a django site through Apache. I also have some Python code that runs as a background process (dameon?). It keeps polling a server and inserts data into one of the Django models. This works fine but can I have this code be a part of my Django application and yet able to constantly run in the background? It doesn't need to be a process per se but a art of the Django site that is active constantly. If so, could you point me to an example or some documentation that

How to package a Python daemon with setuptools

问题 How do you package a Python app with setuptools so that when it's installed (e.g. via setup.py or pip), it places a daemon script in the appropriate location, starts it, and marks it to automatically start at boot time? In my case, my code only works with Linux, so I only care about installing the daemon in Linux environments (specifically Ubuntu). I've found several posts describing how to easily create Python daemons, but I can't seem to find anything describing how you'd install them in a

What is the de facto library for creating Python Daemons

问题 I am attempting to use the python-daemon library which seemed to me to be the safest way to create a Daemon without forgetting anything. The documentation is quite poor, being just PEP 3143. On the other hand , I have found a lot of links to Sander Marechal's A simple unix/linux daemon in Python. This looks to be a nicer solution or though I have not yet attempted to use it. Edit: I have used Sander Marechal's solution and it seems to work nicely. So what is the de facto way in the Python
