nginx 配置文件

1.配置文件结构

Nginx的配置文件是一个纯文本文件，它一般位于Nginx安装目录的conf目录下，整个配置文件是以block的形式组织的。每个block一般以一组大括号“{}”来表示，block可以分为以下几个层次：main层、events层、http层等，而在http层中又包含有server层，即server block，server block 中又可分为location层，并且一个server block中可以包含多个location block。

如下：

#main层

……

events{

……

}

http{

……

   server{

   ……

       location{

       ……

        }

   }

}

mian层：全局配置，影响其他所有设置。

server层：主机配置，主要用于指定主机和端口。

upstream：负载均衡服务器设置，主要用于负载均衡，设置一系列后端服务器。

location：URL匹配特定位置的设置，用于匹配网页设置。

四者之间的关系：server继承main，location继承server，upstream既不会继承其他设置也不会被继承。
