Autorun configuration

Certainly! Here are the detailed steps to configure Supervisor to automatically start your Gunicorn server on system boot:

1. Install Supervisor:

   • On Ubuntu or Debian:

     sudo apt-get install supervisor
     

   • On CentOS or RHEL:

     sudo yum install supervisor
     

2. Create a Supervisor configuration file for your API:

   • Create a new file with a .conf extension (e.g., crack_analyzer_api.conf) in the Supervisor configuration directory (usually /etc/supervisor/conf.d/).
   • Open the file in a text editor with sudo privileges, for example:

     sudo nano /etc/supervisor/conf.d/crack_analyzer_api.conf
     

3. Add the following configuration to the file:

   [program:crack_analyzer_api]
   directory=/path/to/your/api/directory
   command=/path/to/your/virtual/environment/bin/gunicorn --bind 0.0.0.0:5000 crack_analyzer_api:app
   autostart=true
   autorestart=true
   startretries=3
   stderr_logfile=/var/log/crack_analyzer_api.err.log
   stdout_logfile=/var/log/crack_analyzer_api.out.log
   user=your_username
   

   Replace the following placeholders:

   • /path/to/your/api/directory: The directory where your crack_analyzer_api.py file is located.
   • /path/to/your/virtual/environment/bin/gunicorn: The path to the Gunicorn executable in your virtual environment.
   • your_username: The username under which you want to run the API process.

   Save the file and exit the text editor.

4. Update Supervisor configuration:

   sudo supervisorctl reread
   sudo supervisorctl update
   

   This will make Supervisor aware of the new configuration file.

5. Start your API using Supervisor:

   sudo supervisorctl start crack_analyzer_api
   

   This will start your Gunicorn server and make your API accessible.

6. Configure Supervisor to start on system boot:

   • On Ubuntu or Debian:
     • The Supervisor daemon should already be configured to start on boot by default.
   • On CentOS or RHEL:
     • Open the Supervisor configuration file:

       sudo nano /etc/supervisord.conf
       

     • Uncomment the following line to enable Supervisor to start on boot:

       [supervisord]
       ...
       autostart=true
       ...
       

     • Save the file and exit the text editor.

7. Reboot your system to test the automatic startup:

   sudo reboot
   

   After the reboot, your Gunicorn server should automatically start, and your API should be accessible.

You can check the status of your API process using the following command:

sudo supervisorctl status crack_analyzer_api

If you encounter any issues or need to manage your API process, you can use Supervisor commands like start, stop, restart, and status with sudo supervisorctl.

By following these steps, you can configure Supervisor to automatically start your Gunicorn server and your API on system boot, ensuring that your API is always available without manual intervention.
