Main configuration file (nginx.conf) - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the nginx.conf file?

The nginx.conf file is the main configuration file for the NGINX web server. It controls how NGINX behaves, including server settings, modules, and how requests are handled.

beginner

Name the main blocks inside nginx.conf.

The main blocks are: events (handles connection processing), http (handles web traffic), and server (defines virtual hosts).

beginner

What does the worker_processes directive control?

It sets how many worker processes NGINX will run. More workers can handle more connections, like having more cashiers in a store to serve customers faster.

beginner

Explain the role of the server block in nginx.conf.

The server block defines a virtual server. It tells NGINX how to respond to requests for a specific domain or IP, including ports, root folders, and rules.

beginner

How do you reload NGINX after changing nginx.conf without downtime?

Use the command nginx -s reload. This tells NGINX to apply changes smoothly without stopping the server, like changing a light bulb without turning off the room.

Which block in nginx.conf handles web traffic settings?

A http

B events

C server

D location

The http block manages web traffic settings like headers, compression, and proxy settings.

What does the worker_connections directive specify?

A Number of worker processes

B Number of connections each worker can handle

C Port number for the server

D Timeout for client connections

worker_connections sets how many connections each worker process can handle at the same time.

Where do you define the root folder for your website in nginx.conf?

A Inside the <code>http</code> block only

B Inside the <code>events</code> block

C In the <code>worker_processes</code> directive

D Inside the <code>server</code> block

The root folder is set inside the server block, telling NGINX where to find website files.

What command reloads NGINX configuration without downtime?

A nginx -s reload

B nginx -s stop

C nginx -s start

D nginx -s restart

nginx -s reload reloads the config smoothly without stopping the server.

Which directive controls how many worker processes NGINX runs?

A server_name

B worker_connections

C worker_processes

D listen

worker_processes sets the number of worker processes.

Describe the main sections of the nginx.conf file and their roles.

Think of how NGINX organizes its tasks like a team with different roles.

Explain how to safely apply changes made to nginx.conf without stopping the web server.

Imagine changing a part of a machine while it keeps running.
