Introduction

The implementation of the config needs the presence of 2 main components, which are:

• Directives
• Contexts

Directive

Technically, everything inside Nginx Configuration is a Directive.

Directives include 2 types:

• Simple Directives
• Block Directives

Simple Directive

Simple Directive, they are simply commands or parameters separated by spaces like listen, return and they usually end with a semicolon ;.

Block Directive

Block Directives are similar to Simple Directives, but instead of ending the command with a semicolon ;, they end with a pair of curly braces {}.

A Block Directive will contain many Directives inside, and we call that context. Some common types of context are:

• events {}
• Used to specify how nginx can handle requests on the server
• There is only one active events context in the Configuration File
• http {}
• Used to specify how nginx can handle requests as http or https
• There is only one http context in the Configuration File
• server {}
• Placed inside the http context
• Used to set specific information for a specific virtual server in a single server
• There can be multiple server contexts inside the http context
• Each server configuration is considered a virtual server
• main
• Contains general configuration information of Configuration Files.
• What needs to be specified outside the three headings will be written in this context.
