Nginx 指令

Nginx 由配置文件中定义的指令控制的模块组成。指令分为两部分:

  • 简单指令:简单指令由名称和参数组成,以空格分隔并以分号 ; 结尾。
  • 块指令:块指令的结构类似于简单指令,但它不是以分号结尾,而是以一组用大括号 { 和 } 括起来的附加指令结尾。如果块指令在大括号内包含其他指令,则它被称为上下文 (context)。例如,Events、http、location 和 server。

配置文件中放置在任何上下文之外的指令都被认为是在主上下文中events http 指令在主上下文中server 指令在 http 上下文, location 指令在 server 上下文。

让我们看看一些重要指令的列表:
