mpdaemon

Wrapper of python-daemon (with modification) for easy use.

Installation

Source

git clone https://github.com/mptnt1988/mpdaemon.git
cd mpdaemon
pip3 install .

PyPI

pip3 install mpdaemon

Usage

APIs

daemon = DaemonWrapper(serviceName=None, func=None, *args, **kwargs)

If serviceName is None, it defaults to script's ext-stripped filename.

func(*args, **kwargs) will be executed when running daemon.run()

daemon.run(func=None, *a, **ka)

Execute specified func(*a, **ka). If func is None, daemon's func & args initialized in the constructor is executed.

Implementation

See examples

Running

Assume that script file is script.py

python3 script.py start
python3 script.py status
python3 script.py restart
python3 script.py stop

Log file is ~/.mpdaemon/log/<service_name>.log

PID file is ~/.mpdaemon/pid/<service_name>.pid

(<service_name> is specified in script.py or 'script' by default)

Examples

Example 1

example1.py

from mpdaemon import DaemonWrapper
import time


def log_to_file(daemon):
    while True:
        daemon.logger.info("Testing")
        time.sleep(1)


if __name__ == "__main__":
    daemon = DaemonWrapper()
    daemon.run(log_to_file, daemon)

Example 2

example2.py

from mpdaemon import DaemonWrapper
import time
import schedule


def job():
    exec(open("/tmp/writeDate.py").read())


def scheduling(t_mins):
    schedule.every(t_mins).minutes.do(job)
    while True:
        schedule.run_pending()
        time.sleep(1)


if __name__ == "__main__":
    daemon = DaemonWrapper(None, scheduling, 1)
    daemon.run()

/tmp/writeDate.py

import datetime


with open('/tmp/dateInfo.txt', 'a') as outFile:
    outFile.write(str(datetime.datetime.now()) + '\n')
