💼 Career

Many DevOps and system admin jobs require managing nginx or similar servers, so knowing config structure is essential.

1

Create the basic nginx configuration structure

Create a variable called nginx_config and set it to a string containing the basic nginx configuration with an empty server block like this:

server {

}

Nginx

# Your code here

Need a hint?

Remember to use double quotes and include the newline characters \n inside the string.

2

Add the listen directive inside the server block

Update the nginx_config string to include the line listen 80; inside the server block, right after the opening brace.

Nginx

nginx_config = "server {\n    # Add listen directive here\n}"

Need a hint?

Indent the listen 80; line with 4 spaces inside the server block.

3

Add the server_name directive inside the server block

Add the line server_name example.com; inside the server block, below the listen 80; line in the nginx_config string.

Nginx

nginx_config = "server {\n    listen 80;\n    # Add server_name directive here\n}"

Need a hint?

Keep the same indentation as the listen line.

4

Add a location block and print the configuration

Add a location / block inside the server block with the line root /var/www/html; inside it. Then print the full nginx_config string.

Nginx

nginx_config = "server {\n    listen 80;\n    server_name example.com;\n    # Add location block here\n}"

# Print the nginx_config below

Need a hint?

Make sure the location block is indented inside the server block and the root line is indented inside the location block.
