Reverse proxies play a crucial role in enhancing the performance and security of web applications. In a Linux environment, reverse proxies can be implemented using popular open-source software like Nginx and Apache. This article will provide an informative and instructional guide on how to set up and configure a reverse proxy in a Linux environment, focusing on Nginx as the chosen software.

Examples:

1. Installing Nginx: To install Nginx on a Linux system, open the terminal and run the following command:

   sudo apt update
   sudo apt install nginx

2. Configuring Nginx as a Reverse Proxy: Open the Nginx configuration file located at /etc/nginx/nginx.conf using a text editor. Add the following code inside the http block to configure Nginx as a reverse proxy for a web application running on localhost port 8080:

   server {
      listen 80;
      server_name example.com;
   
      location / {
          proxy_pass http://localhost:8080;
          proxy_set_header Host $host;
          proxy_set_header X-Real-IP $remote_addr;
      }
   }

3. Restarting Nginx: After making changes to the Nginx configuration, restart the Nginx service using the following command:

   sudo systemctl restart nginx
