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  4;

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

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

    client_header_buffer_size    128k;
    large_client_header_buffers  4 128k;
    ############你自己的项目#######
      upstream dj-tomcatwebapp {
   #     sticky;
        server 127.0.0.1:8085;
    }
###### 你自己的项目system#######   
    server {
        listen       8095;
        server_name  127.0.0.1; 70         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; 
            
        }
        
118     }
    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
