nginx代理tomcat后，tomcat获取真实（非proxy,非别名）nginx服务端ip端口的解决方案

nginx代理tomcat后，tomcat获取服务端ip端口的解决方案

1.注意修改nginx配置代理，标红地方

 #user  nginx;
 worker_processes  ;

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

 pid        logs/nginx.pid;

 events {
     worker_connections  ;
 }

 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  ;
     keepalive_timeout  ;

     gzip  on;
     gzip_disable "MSIE [1-6].";

     client_header_buffer_size    128k;
     large_client_header_buffers   128k;
     ############你自己的项目#######
       upstream dj-tomcatwebapp {
    #     sticky;
         server 127.0.0.1:;
     }
 ###### 你自己的项目system#######
     server {
         listen       ;
         server_name  127.0.0.1;         charset utf-8;

         #access_log  logs/host.access.log  main;

         location / {
             client_max_body_size    1000m;
             proxy_pass  http://dj-tomcatwebapp;
             proxy_redirect          off;
 78               proxy_set_header Host $host:$server_port;
 79               proxy_set_header X-Real-IP $remote_addr;
 80                 proxy_set_header X-Real-PORT $remote_port;
 82               proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

             proxy_next_upstream error timeout invalid_header http_500 http_503 http_404; 

         }

     }
      }

2.jsp获取真实服务器  nginx访问 ip 端口

<%
String scheme = request.getScheme();
String serverName = request.getServerName();
int port = request.getServerPort();
String requestURI = scheme+"://"+serverName+":"+port;
 %>
<c:set var="hyrt" value="<%=requestURI%>" />

以上经过实际本地测试，可以正常获取
