Location blocks in Nginx - Mini Project: Build & Apply

Configuring Nginx Location Blocks

📖 Scenario: You are setting up a simple web server using Nginx. You want to serve different content based on the URL path requested by users.For example, requests to /images should serve image files from a specific folder, and requests to /api should be forwarded to a backend server.

🎯 Goal: Learn how to create and configure location blocks in an Nginx configuration file to route requests based on URL paths.

📋 What You'll Learn

Create a basic Nginx server block

Add a location block for /images to serve static files

Add a location block for /api to proxy requests to a backend server

Print the final Nginx configuration

💡 Why This Matters

🌍 Real World

Nginx is widely used to serve websites and route requests to different services. Location blocks help control how different URL paths are handled.

💼 Career

Understanding Nginx configuration and location blocks is essential for DevOps roles managing web servers and application deployments.

1

Create the basic Nginx server block

Create a variable called nginx_config and assign it a string containing a basic Nginx server block listening on port 80 with the server name example.com.

Nginx

# Your code here

Need a hint?

Start with server { and include listen 80; and server_name example.com; inside.

2

Add a location block for /images

Add a location block for /images inside the nginx_config string that serves static files from /var/www/images. Append this block inside the existing server block.

Nginx

nginx_config = '''server {
    listen 80;
    server_name example.com;
    # Add location block for /images here
}'''

Need a hint?

Use location /images { and inside set root /var/www; to serve files from /var/www/images.

3

Add a location block for /api to proxy requests

Add a location block for /api inside the nginx_config string that proxies requests to http://localhost:3000. Append this block inside the existing server block after the /images location.

Nginx

nginx_config = '''server {
    listen 80;
    server_name example.com;

    location /images {
        root /var/www;
    }
    # Add location block for /api here
}'''

Need a hint?

Use location /api { and inside set proxy_pass http://localhost:3000; to forward requests.

4

Print the final Nginx configuration

Write a print statement to display the full nginx_config string.

Nginx

print(nginx_config)  # Print the final configuration

Need a hint?

Use print(nginx_config) to show the full configuration.
