Worker processes and connections in Nginx - Interactive Code Practice

Practice - 5 Tasks

easy

Complete the code to set the number of worker processes to 4.

Nginx

worker_processes [1];

💡 Hint

Common Mistakes

Using 'auto' instead of a number when a fixed number is required here.

The worker_processes directive sets how many worker processes Nginx will use. Setting it to 4 means Nginx will run 4 worker processes.

Complete the code to set the maximum number of simultaneous connections per worker to 1024.

Nginx

events {
    worker_connections [1];
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Choosing a value too low that limits connections unnecessarily.

The worker_connections directive inside the events block sets the maximum number of simultaneous connections each worker process can handle. Setting it to 1024 allows each worker to handle up to 1024 connections.

Fix the error in the configuration line to correctly set worker processes to automatically match CPU cores.

Nginx

worker_processes [1];

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'automatic' or 'cpu' which are not valid keywords.

The correct keyword to automatically set worker processes to the number of CPU cores is auto. Other options are invalid and cause errors.

4fill in blank

hard

Fill both blanks to set worker processes to 2 and worker connections to 2048.

Nginx

worker_processes [1];
events {
    worker_connections [2];
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing up the values for worker processes and worker connections.

Setting worker_processes to 2 means Nginx will run 2 worker processes. Setting worker_connections to 2048 allows each worker to handle up to 2048 simultaneous connections.

5fill in blank

hard

Fill all three blanks to configure worker processes to auto, worker connections to 512, and set multi_accept to on.

Nginx

worker_processes [1];
events {
    worker_connections [2];
    multi_accept [3];
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Setting multi_accept to 'off' when 'on' is needed for performance.

Setting worker_processes to auto lets Nginx detect CPU cores. worker_connections set to 512 limits connections per worker. multi_accept on allows a worker to accept multiple new connections at once, improving performance.
