nginx 搭建图片资源服务器小编这里涉及2个版本：windows下 和 linux下 

首先去nginx官方网站下载nginx安装包

http://nginx.org/en/download.html

可看到当前nginx最新版本，小编采用的是nginx-1.9.10

windows版本：

通过nginx官网下载nginx的windows版本安装包后 直接解压到指定目录可看到

每个包文件所代表的意义在前面章节已经有所介绍这里就不做过多描述了

打开conf文件夹下nginx.conf文件

修改用户使用权限，开放user 如果不开放会报错404，追加最大连接数

修改server块

修改监听端口号：8088；

指定图片存放路径，可使用系统默认，也可以指定

指定代理临时路径，图片标红处

代理访问地址

以上都可以通过配置域名进行直接绑定访问

}

修改完成后启动nginx.exe

访问http://127.0.0.1:8088 查看nginx是否监听并成功启动

访问：http://127.0.0.1:8088/tempupload/temp20170907/0a9862d7043445d68c5cb270d47db166.png

OK 以上 windows下搭建nginx 图片服务器就搞定啦

linux下：

linux下其实和windows下没有太大的差异，只需要主要用户权限是否开放就好，下面我介绍一种我们在做反向代理及负载均衡情况下如何搭建，使nginx做代理转发废话不多说 直接上图，通过upstream做负载，通过ip_hash轮训算法去判断转发到哪个服务上，这里小编只采用一台虚拟机进行配置，实际上不管是一台还是多台都是适用的，因为转发的时候 实际上是通过upstream的名称进行转发

user  root;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

worker_rlimit_nofile 655350;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
      include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;


    upstream blog {
      server 192.168.153.20 ;
      ip_hash;

    }

     server {
        listen 80;
        server_name  picture.sht18.com;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;


    upstream blog {
      server 192.168.153.20 ;
      ip_hash;

    }

     server {
        listen 80;
        server_name  picture.sht18.com;

        location ~ .*\.(gif|jpg|jpeg|png)$ {
            expires 24h;
            root /root/imgs/;#指定图片存放路径
            access_log /root/nginx/logs/images.log;#图片 日志路径
            proxy_store on;
            proxy_store_access user:rw group:rw all:rw;
            proxy_temp_path         /root/imgs/;#代理临时路径
            proxy_redirect          off;

            proxy_set_header        Host 127.0.0.1;
            proxy_set_header        X-Real-IP $remote_addr;
            proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
            client_max_body_size    10m;
            client_body_buffer_size 1280k;
            proxy_connect_timeout   900;
            proxy_send_timeout      900;
            proxy_read_timeout      900;
            proxy_buffer_size       40k;
            proxy_buffers           40 320k;
            proxy_busy_buffers_size 640k;
            proxy_temp_file_write_size 640k;
            if ( !-e $request_filename)
            {
                 proxy_pass  http://blog;#代理访问地址
            }
        }
    }
}

剩下的 就和windows下是一样的
