Run script on remote server from Django webserver

I have a basic (server1) Django development web server and another server (server2) that has a python script that does some scientific calculations. Let's assume server1 has the required authentication to run the script on server2. All I want to do is click a button on the django website that will run the python script while sitting on the server2.

The ideas that I still have

  • use some ssh library to run your script and get the response
  • you have a REST API setup on server2 to run your script

Not sure if the ideas will work, please offer your understanding of this and a simple example would be appreciated if possible.

Additional information: Server1 and Server2 must be 2 separate servers, server1 is the web server and server2 is any Linux virtual machine. Also, the response from server2 must be sent back to server1.

After reading and trying out various forum suggestions and spending a lot of time on Google, I settled in with paramiko. It does what I wanted and now it works like a charm.

When a button is clicked on my website running on server1, I make a request to run a python script. The Python script uses paramiko to SSH into server2, runs the required command and writes a response to a plain / text file. This plain / text file is returned to the request via the django form as a response.



It looks a little messy now, and there are more things to see how that happens if the command took a very long time to complete, or it was wrong for some reason. I haven't taken the time to figure out the answers to all of these questions, but eventually I will.

There is no reason the server can't execute something like selenium or phantomjs on itself to go to your site on server2 and click a button on server2, which then uses something like a python subprocess module to execute the program from server2.
