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

  1 #user  nginx;
  2 worker_processes  4;
  3 
  4 error_log  logs/error.log;
  5 #error_log  logs/error.log  notice;
  6 #error_log  logs/error.log  info;
  7 
  8 pid        logs/nginx.pid;
  9 
 10 
 11 events {
 12     worker_connections  1024;
 13 }
 14 
 15 
 16 http {
 17     include       mime.types;
 18     default_type  application/octet-stream;
 19 
 20     log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
 21                       '$status $body_bytes_sent "$http_referer" '
 22                       '"$http_user_agent" "$http_x_forwarded_for"';
 23 
 24     access_log  logs/access.log  main;
 25 
 26     sendfile        on;
 27     #tcp_nopush     on;
 28 
 29     #keepalive_timeout  0;
 30     keepalive_timeout  65;
 31 
 32     gzip  on;
 33     gzip_disable "MSIE [1-6].";
 34 
 35     client_header_buffer_size    128k;
 36     large_client_header_buffers  4 128k;
 37     ############你自己的项目#######
 38       upstream dj-tomcatwebapp {
 39    #     sticky;
 40         server 127.0.0.1:8085;
 41     }
 65 ###### 你自己的项目system#######   
 66     server {
 67         listen       8095;
 68         server_name  127.0.0.1; 70         charset utf-8;
 71 
 72         #access_log  logs/host.access.log  main;
 73         
 74         location / {
 75             client_max_body_size    1000m;
 76             proxy_pass  http://dj-tomcatwebapp;
 77             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;
 86            
 87                 
 88             proxy_next_upstream error timeout invalid_header http_500 http_503 http_404; 
 89             
 90         }
 91         
 92118     }
119     162204 }

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
