Systemd service

Ref ​here

1. Setup script to run as service called test.py

   import time
   from datetime import datetime
   while True:
       with open("timestamp.txt", "a") as f:
           f.write("The current timestamp is: " + str(datetime.now()))
           f.close()
       time.sleep(10)
   

2. nano /etc/systemd/system/test.service (name of the service which is test in this case)

   [Unit]
   Description=My test service
   After=multi-user.target
   
   [Service]
   Type=simple
   Restart=always
   ExecStart=/usr/bin/python3 /home/<username>/test.py
   
   [Install]
   WantedBy=multi-user.target
   

3. reload systemctl daemon

   sudo systemctl daemon-reload
   sudo systemctl enable test.service
   sudo systemctl start test.service
   sudo systemctl stop test.service
   sudo systemctl restart test.service
   sudo systemctl status test.service
