Auto reboot server every sunday and run a python script in tmux d

When it comes to automating tasks in Python, there are several ways to solve the problem of auto rebooting a server every Sunday and running a Python script in tmux. In this article, we will explore three different approaches to achieve this goal.

Option 1: Using the os module

The first option involves using the os module in Python to execute system commands. We can use the os.system() function to run the necessary commands to reboot the server and start the Python script in tmux.

import os

# Reboot the server
os.system('sudo reboot')

# Run the Python script in tmux
os.system('tmux new-session -d -s mysession "python script.py"')

This approach is simple and straightforward. However, it relies on the availability of the os.system() function and may not be the most robust solution.

Option 2: Using the subprocess module

The second option involves using the subprocess module, which provides more flexibility and control over executing system commands. We can use the subprocess.run() function to run the necessary commands to reboot the server and start the Python script in tmux.

import subprocess

# Reboot the server
subprocess.run(['sudo', 'reboot'])

# Run the Python script in tmux
subprocess.run(['tmux', 'new-session', '-d', '-s', 'mysession', 'python', 'script.py'])

This approach is more robust and recommended when working with system commands in Python. It allows for better error handling and capturing the output of the commands if needed.

Option 3: Using a cron job

The third option involves setting up a cron job to schedule the server reboot and script execution. Cron is a time-based job scheduler in Unix-like operating systems. We can create a cron job that runs every Sunday and executes the necessary commands.

To set up a cron job, open the crontab file by running the command crontab -e in the terminal. Add the following lines to the file:

# Reboot the server every Sunday at 00:00
0 0 * * 0 sudo reboot

# Run the Python script in tmux every Sunday at 01:00
0 1 * * 0 tmux new-session -d -s mysession "python script.py"

This approach provides more flexibility in scheduling and managing the tasks. However, it requires access to the crontab file and may not be suitable for all environments.

After exploring these three options, the recommended approach would be Option 2: Using the subprocess module. It offers better control and error handling compared to Option 1, and it is more flexible and manageable than Option 3. However, the choice ultimately depends on the specific requirements and constraints of the project.

  1. I personally prefer option 2 because it adds some spice to the server reboot dance. Whos with me? 🕺💃

    1. Option 2 sounds like a disaster waiting to happen. Why risk compromising the stability of the server reboot? Id rather stick to the tried and tested method. Safety over spice, my friend. 💁‍♂️

  2. Option 3: Using a cron job? More like Option 3: Boring! Bring on the excitement with Option 4: A dancing monkey! 🐵🎉
