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?
2 Answers
You can create a systemd service on the ec2 instance to achieve this. Steps are:
Create a service definition file:
sudo vi /lib/systemd/system/mypythonservice.serviceAdd 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.targetSet the necessary permissions on the file:
sudo chmod 644 /lib/systemd/system/mypythonservice.serviceReload the systemd daemon:
sudo systemctl daemon-reloadEnable 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.

We use sysvinit and not systemd. Any suggestion for that?

You can have a look at this stackoverflow.com/questions/16420092/… or this: gist.github.com/int64ago/01fe54e45ffc28442c20

I would also add
systemctl start myservice.service to start the process and then check the status using systemctl status myservice.service to this answer.
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.
See the solution in this link.
