Nginx Configuration Fundamentals

Configuration Syntax

Nginx configuration uses simple directive and block syntax:

directive value;

block_name {
    nested_directive value;
}

Key Rules:

• Every directive ends with semicolon (;)
• Blocks use curly braces
• Comments use hash symbol (#)

Example Configuration

user nginx;
worker_processes auto;

http {
    include mime.types;

    server {
        listen 80;
        server_name example.com;
        root /var/www;

        location / {
            try_files $uri =404;
        }
    }
}
