Use pm2 with Django

Question

I have just changed from Express with NodeJS to Django with Python. The only thing I miss about NodeJS was the wonderful process manager pm2. Can I use pm2 with Django?

Answer 1

You can define a pm2 script e.g

pm2{name}.json

with the following contents:

 {
  "apps": [
    {
      "name": "{name}",
      "cwd": "/srv/{name}",
      "args": "runserver",
      "script": "manage.py",
      "exec_mode": "fork",
      "exec_interpreter": "python"
    }
  ]
}

and run it with pm2 start {name}

obviously you need to replace {name} with your project's name.

Steps

• Install Node from given link
• Install npm using this command in command prompt / terminal reference

npm install npm@latest -g

• Run this command for execute django application non stop on server machine

     pm2 start echosystem.config.json
     Description of echosystem.config.json

{       
   apps:            
      [{
        name: "djnago_with_pm2",          
        script: "manage.py",
        args: ["runserver", "127.0.0.1:8000"], 
        exec_mode: "fork", 
        instances: "1", 
        wait_ready: true, 
        autorestart: false, 
        max_restarts: 5, 
        interpreter : "python" 
      }] 
}    

• If we have to change the port number of our django application, then we can change the port no in args attribute of echosystem.config.json file. After done the changes in echosystem.config.json file, stop the server using

• List item

  pm2 command like this:

  • pm2 stop all // this command will stop all server.
  • pm2 stop 0 // if you know the pm2 id then execute command like this.
  • pm2 start echosystem.config.json // again start the django application.
