Configure a Python as a service in AWS EC2

Question

How do I configure a Python script to run as a service (re-launch on system restart, restart on failure) in Amazon AWS EC2 instance?

Answer 1

You can create a systemd service on the ec2 instance to achieve this. Steps are:

1. Create a service definition file:

   sudo vi /lib/systemd/system/mypythonservice.service
   

2. Add the systemd unit file definition. You can check this or the systemd reference guide for more details:

   [Unit]
   Description=My Python Service
   After=multi-user.target
   
   [Service]
   Type=idle
   ExecStart=/usr/bin/python /home/myuser/mypythonproject.py
   Restart=on-failure
   
   [Install]
   WantedBy=multi-user.target
   

3. Set the necessary permissions on the file:

   sudo chmod 644 /lib/systemd/system/mypythonservice.service
   

4. Reload the systemd daemon:

   sudo systemctl daemon-reload
   

5. Enable the service to start on reboot:

   sudo systemctl enable mypythonservice.service
   

And of course you can add all of this as part of a EC2 Instance User Data script to automatically configure on instance launch.

Configure a Python as a service in AWS EC2

After much unsuccessful research to set up a Python API written on custom port 8080 to run on Amazon's Linux AMI operating system (AWS), I decided to solve this dilemma and share the solution with all of you.
