NGINX 指令2024 年 8 月 29 日 | 阅读 2 分钟 Nginx 由模块组成，这些模块由配置文件中定义的指令控制。 指令分为两部分 - 简单指令： 简单指令由名称和用空格分隔的参数组成，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，而是以一组由大括号 ({ 和 }) 括起来的附加指令结尾。 如果块指令可以在大括号内包含其他指令，则称其为上下文。 例如。 Events, http, location 和 server。
放置在任何上下文之外的配置文件中的指令被认为位于 main 上下文 中。 events 和 http 指令位于 main 上下文，server 位于 http 上下文，location 位于 server 上下文。 让我们看看一些重要的指令的列表 | 指令 | 语法 | 默认 | 背景 |
