linux之 nginx.conf 解析版、原版、项目使用版（官方文档）

一、解析版

## nginx进程数，建议设置为等于CPU总核心数。
worker_processes  1;
## 事件区块开始
events {
## 单个进程最大连接数（最大连接数=连接数*进程数）
## 根据硬件调整，和前面工作进程配合起来用，尽量大，但是别把cpu跑到100%就行。每个进程允许的最多连接数，理论上每台nginx服务器的最大连接数为。
    worker_connections  1024;
}
## 设定http服务器，利用它的反向代理功能提供负载均衡支持
http {
## include：导入外部文件mime.types，将所有types提取为文件，然后导入到nginx配置文件中
    include       mime.types;
## 默认文件类型
    default_type  application/octet-stream;
## 开启高效文件传输模式，sendfile指令指定nginx是否调用sendfile函数来输出文件，对于普通应用设为 on，如果用来进行下载等应用磁盘IO重负载应用，可设置为off，以平衡磁盘与网络I/O处理速度，降低系统的负载。注意：如果图片显示不正常把这个改成off。
## sendfile指令指定 nginx 是否调用sendfile 函数（zero copy 方式）来输出文件，对于普通应用，必须设为on。如果用来进行下载等应用磁盘IO重负载应用，可设置为off，以平衡磁盘与网络IO处理速度，降低系统uptime。
    sendfile        on;
## 长连接超时时间，单位是秒
    keepalive_timeout  65;
## 第一个Server区块开始，表示一个独立的虚拟主机站点
    gzip on; # 默认off，是否开启gzip
    gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

## 上面两个开启基本就能跑起了，下面的愿意折腾就了解一下
    gzip_static on;
    gzip_proxied any;
    gzip_vary on;
    gzip_comp_level 6;
    gzip_buffers 16 8k;
    # gzip_min_length 1k;
    gzip_http_version 1.1;
# 第一个网站：个人博客项目配置
    server {
	  	listen       8080;
	  	root         /data/www/hexo;
	  	index        index.html;
	  	location / {
	  		try_files $uri $uri/ /index.html; # 路由模式history的修改
	  	}
    }

## 第二个网站：GeoV网站项目配置
    server {
    	listen       8081;
    	root         /data/www/geov;
    	index        index.html;
    	location / {}
    }
## 第三个网站：
    server {
## 提供服务的端口，默认80
        listen       80;
## 提供服务的域名主机名
        server_name  localhost;
## 对 "/" 启用反向代理,第一个location区块开始
        location / {
            root   html;  #服务默认启动目录
            index  index.html index.htm; # 默认的首页文件，多个用空格分开
        }
## 接口端
        location /police/ {
            proxy_pass   http://192.168.1.182:8852/police/;
            proxy_redirect default;
            proxy_http_version 1.1;
            proxy_connect_timeout   60;
            proxy_send_timeout      60;
            proxy_read_timeout      90;
        }
## py接口端
        location /py/ {
            proxy_pass   http://192.168.1.182:8852/py/;
            proxy_redirect default;
            proxy_http_version 1.1;
            proxy_connect_timeout   60;
            proxy_send_timeout      60;
            proxy_read_timeout      90;
        }
## 错误页面路由
        error_page   500 502 503 504  /50x.html; # 出现对应的http状态码时，使用50x.html回应客户
        location = /50x.html { # location区块开始，访问50x.html
            root   html;  # 指定对应的站点目录为html
        }
    }

}
