        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

    }
}

worker_processes

worker_processes 1 ; 默认为 1 ，表示开启一个业务进程

worker_connections

worker_connections 1024 ; 单个业务进程可接受连接数

include mime.types;

include mime.types ; 引入 http mime 类型

default_type application/octet-stream;

default_type application/octet - stream ; 如果 mime 类型没匹配上，默认使用二进制流的方式传输。

sendfifile on;

sendfile on ; 使用 linux 的 sendfile(socket, file, len) 高效网络传输，也就是数据 0 拷贝。

未开启 sendfifile，此时nginx从磁盘拷贝请求资源后，到网络接口缓存之间仍需要经过多次拷贝

开启后，只需要一个信号，读取一次【Nginx基础篇】nginx的基本配置解析和应用场景

keepalive_timeout 65; 连接保持心跳时间，这里分为客户端和被代理端，以后会介绍

server，一个server可以表示一台主机，所以配置多个server可以有多态虚拟主机（vhost）

虚拟主机配置文章来源地址https://www.toymoban.com/news/detail-443016.html

server {
    listen 80; 监听端口号
    server_name localhost; 主机名
    location / { 匹配路径
        root html; 文件根目录
        index index.html index.htm; 默认页名称
    }
    error_page 500 502 503 504 /50x.html; 报错编码对应页面
    location = /50x.html {
        root html;
    }
}
