Install the application

To install an application, perform the following steps:

1. Log in to the server via SSH as a cPanel user.

2. Create the application’s directory, relative to your home directory. To do this, run the following command, where directoryname represents the application’s directory:

   mkdir directoryname

3. Change to the application’s directory. To do this, run the following command, where directoryname represents the application’s directory:

   cd directoryname

4. Copy the application to your server.

5. Create the passenger_wsgi.py file. In this example, pythonapp represents your python application and MyApp represents an application function:

   echo "from pythonapp import MyApp as application" > passenger_wsgi.py

6. Install the application’s dependencies. To do this, run the following command:

   pip install --user -r requirements.txt
    
   Note:

   You can also install any dependencies in the Ensure Dependencies section of cPanel’s Application Manager interface (cPanel >> Home >> Software >> Application Manager).

    

Test the application

After you install the application, we recommend that you confirm that it’s active.

1. Run the following command:

   python pythonapp.py
    
   The output might resemble the following example:

   <!DOCTYPE html> … <section class="main"> <h1>Hello world!</h1> Welcome to the example app. </section> </body> </html>

    

2. Open another terminal window and log in to the server via SSH as the same cPanel user.

3. Run the following command:

   curl http://localhost:5000
   The output will resemble the following example:
   Hello, World!

    

Register the application

After you install the application, register it. To do this, use cPanel’s Application Manager interface (cPanel >> Home >> Software >> Application Manager).

You can then access the application in a web browser with the following url:

Restart the application

To restart your application after you edit it, create the restart.txt touch file. Create this file in the application’s /tmp directory. This file directs Phusion Passenger® to restart the application after you modify it. This action applies your changes to the application.
