nginx反向代理arcgis server和地形切片数据

1、下载nginx软件：官网地址http://nginx.org/

2、修改conf文件夹下nginx.conf配置信息，

 配置文件中以下内容：  

server {

        listen       80;

        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {

            root   html;

            index  index.html index.htm;

        }

按需要改为如下：

upstream arcgis{

	  server http://192.168.1.76:6080/;   

	}
    server {
        listen       16165;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
		    add_header 'Access-Control-Allow-Origin' $http_origin;
			add_header 'Access-Control-Allow-Credentials' 'true';
			add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
			add_header 'Access-Control-Allow-Headers' 'DNT,web-token,app-token,Authorization,Accept,Origin,Keep-Alive,User-Agent,X-Mx-ReqToken,X-Data-Type,X-Auth-Token,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
			add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
			if ($request_method = 'OPTIONS') {
				add_header 'Access-Control-Max-Age' 1728000;
				add_header 'Content-Type' 'text/plain; charset=utf-8';
				add_header 'Content-Length' 0;
				return 204;
			}
		   
		
		    #root   html/dem/;
			root html;
			#index index.html;
        }
		# 新加的
        location /ag {
            proxy_pass http://192.168.1.76:6080/;  
		    #代理的arcgis server服务器的地址和端口号 
		    proxy_redirect off;

            proxy_set_header   host             $host;

            proxy_set_header   x-real-ip        $remote_addr;

            proxy_set_header   x-forwarded-for  $proxy_add_x_forwarded_for;

            proxy_next_upstream error timeout invalid_header http_500 http_504 http_404;
        }

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

     
    }

3.要发布静态地形切片数据可将切片文件放置于 nginx-1.17.1\html安装目录下的html文件夹中，配置如上

4、启动nginx，使dos命令，定位到nginx目录下，使用“start nginx.exe”启动nginx。

5、验证：

（1）验证arcgis服务代理

以服务目录http://192.168.1.76:6080/arcgis/rest/services，nginx部署到192.168.1.214服务器为例。

部署成功后，访问http://192.168.1.76:6080/arcgis/rest/services，访问结果应与http://192.168.1.214:16165/ag/arcgis/rest/services访问结果一致。

（2）验证地形切片访问

http://localhost:16165/dem/layer.json

ps：使用nginx还可以配置负载均衡，可参考http://blog.csdn.net/warrenwyf/article/details/5703098
