[Python O & M] Simple Python O & M script and python O & M script
Background

Recently I used the Linux subsystem on Windows 10 and found that it has a very bad character: the Linux subsystem is not in the power-on and shutdown state, and is automatically loaded every time it enters the Bash shell, after exiting, all processes in the Linux subsystem will be shut down. If you try to run services such as Mysql at any time, you must enable the Bash shell at any time, even worse, these services are not automatically started as they enter the Bash shell, so I have to write a Python script to manage these services.

Python scripts are much easier to write than shell scripts.
