Why location matching controls request routing in Nginx - See It in Action

Why location matching controls request routing in nginx

📖 Scenario: You are setting up a simple web server using nginx. You want to control how different web requests are handled based on the URL path. This is important because nginx uses location blocks to decide where to send each request.

🎯 Goal: Learn how to create location blocks in nginx configuration to control request routing based on URL paths.

📋 What You'll Learn

Create an nginx configuration file with a server block

Add a root directory for serving files

Add two location blocks for different URL paths

Print the final nginx configuration to verify the routing setup

💡 Why This Matters

🌍 Real World

Web servers like nginx use location matching to decide how to handle different web requests. This helps serve static files, proxy to backend apps, or block unwanted requests.

💼 Career

Understanding nginx location matching is essential for DevOps roles managing web servers, load balancers, and application delivery.

1

Create the basic nginx server block

Create an nginx configuration with a server block that listens on port 80 and sets the root directory to /var/www/html.

Nginx

# Your code here
# Create a server block listening on port 80 with root /var/www/html

Need a hint?

Use server { ... } to define the server. Inside, use listen 80; and root /var/www/html;.

2

Add a location block for the root URL

Inside the server block, add a location / block that serves files from the root directory.

Nginx

server {
    listen 80;
    root /var/www/html;
    # Add a location block for / here
}

Need a hint?

The location / block matches all requests starting with /. Use try_files $uri $uri/ =404; to serve files or show 404 if not found.

3

Add a location block for /images path

Inside the server block, add a location /images/ block that serves files from /var/www/images directory.

Nginx

server {
    listen 80;
    root /var/www/html;

    location / {
        try_files $uri $uri/ =404;
    }
    # Add a location block for /images/ here
}

Need a hint?

The location /images/ block matches URLs starting with /images/. Use root /var/www; so that nginx looks for files in /var/www/images.

4

Print the final nginx configuration

Print the entire nginx configuration to verify the location blocks and routing setup.

Nginx

# Print the nginx configuration below
# Your code here

Need a hint?

Use a print statement to display the full nginx configuration exactly as written.
