Nginx配置文件结构

nginx consists of modules which are controlled by directives specified in the configuration file. Directives are divided into simple directives and block directives. A simple directive consists of the name and parameters separated by spaces and ends with a semicolon (;). A block directive has the same structure as a simple directive, but instead of the semicolon it ends with a set of additional instructions surrounded by braces ({ and }). If a block directive can have other directives inside braces, it is called a context (examples: events, http, server, and location).

---

Directives placed in the configuration file outside of any contexts are considered to be in themain context. The events and http directives reside in the main context, server in http, and locationin server.

The rest of a line after the # sign is considered a comment.
