Nginx学习笔记——配置文件结构

以下内容翻译自Nginx官方文档，[原文地址]。

---

nginx由模块组成，这些模块由配置文件中的指令进行控制。

nginx consists of modules which are controlled by directives specified in the configuration file.

指令分为简单指令和块指令。

Directives are divided into simple directives and block directives.

一个简单指令由名称和参数组成，用空格分开，以分号结束。

A simple directive consists of the name and parameters separated by spaces and ends with a semicolon (;).

一个块指令和简单指令有相同的结构，但是以花括号包围的一组额外命令结尾，而不是以分号结尾。

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 }).

如果一个块指令可以再花括号内包含其他指令，则称该块指令为一个上下文（例如：events、http、server和location）

If a block directive can have other directives inside braces, it is called a context (examples: events, http, server, and location).

在配置文件中的所有上下文（context）之外的指令被认为是在main上下文中。

Directives placed in the configuration file outside of any contexts are considered to be in the main context.

events和http指令在main上下文中，server在http上下文中，location在server上下文中。

The events and http directives reside in the main context, server in http, and location in server.

其余的在#后面的行是注释。

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

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i <= lines; i++) { $numbering.append($('

').text(i)); }; $numbering.fadeIn(1700); }); });
