Introduction

In this article, we will learn how to set up a local environment and upload a Python application online. We will cover various steps, including creating a subdomain, choosing the right Python version, and troubleshooting internal server errors. By following this guide, You will be able to successfully deploy your Python application and avoid common pitfalls along the way.

Setting up the Local Environment

Before we begin uploading our Python application online, we need to set up a local environment. This involves starting a local server and running our test application. By doing this, we can ensure that our application is functioning correctly before deploying it. Let's start by creating a subdomain for our test application.

Creating a Subdomain

To Create a subdomain, we can use cPanel. By creating a subdomain, we can easily manage our test application and keep it separate from our main Website. Once we have created the subdomain, we can proceed to create a new Python application.

Creating a Python Application

When creating a Python application, it is important to choose the right Python version. We recommend using Python 3.7.1 as it is stable and compatible with most packages. Avoid using Python 2.7 as some recent packages, such as Django, may fail to run on it. Once we have chosen the Python version, we can proceed with setting up the application route.

Setting the Application Route

Setting the application route is crucial for running our Python application correctly. By setting the application route, we ensure that our application is accessible and functions as expected. Additionally, we need to adjust HTML templates to reflect the correct application route.

Uploading the Application Online

After setting up our local environment and making the necessary adjustments, it's time to upload the Python application online. We need to compress our application files into a .zip file and then upload it to our cPanel file manager. Once uploaded, we can extract the files and proceed to adjust the application settings on cPanel.

Extracting the Uploaded Files

Once the application files are uploaded, we need to extract them in the correct location. It is important to ensure that the extracted files are in the correct folder and that any unnecessary files, such as the .zip file, are deleted. After extracting the files, we can proceed to adjust the application settings on cPanel.

Adjusting the Application Settings on cPanel

To adjust the application settings on cPanel, we need to identify the root folder and edit the passenger_wsgi.py file. This file serves as the entry point for our application and needs to be adjusted accordingly. Additionally, we need to install the required packages by running the pip install command.

Troubleshooting Internal Server Errors

Internal server errors can occur when accessing certain pages of our application. In this section, we will troubleshoot these errors and provide solutions. By following the steps outlined, we can address any internal server errors and ensure that our application functions properly.

Conclusion

In conclusion, deploying a Python application online requires proper setup and troubleshooting. By following the steps outlined in this guide, you will be able to successfully upload your application and avoid common pitfalls. Remember to always double-check your settings and make necessary adjustments to ensure a smooth deployment process.
