比如有两个项目，希望访问的端口号都是80端口，可进行如下配置：

    server {
        listen       80;
        server_name  localhost;
	server_name_in_redirect off;
	proxy_set_header Host $host:$server_port;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
	location / {
	    proxy_pass 
        }
	location /group1/M00 {  
	    alias /data/images/data;  
	    ngx_fastdfs_module;  
	} 
    }
