一个nignx 服务反向代理3个IP访问的配置方法

场景：在10.17.55,44:7002和10.17.55.46:7003的weblogic 部署一个web工程，准备做负载均衡。在一台IP：12.17.56.44能访问到55.44和55.46上web工程的机器做nginx代理服务器，代理端口为7000，既12.17.56.44:7000能访问到10.17.55,44:7002或10.17.55.46:7003的web工程，而互联网有个IP22.18.55.33:7000 可以访问到，12.17.56.44:7000，12.17.56.44这台服务器的nginx.conf 内容配置如下：

#user  nobody;

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

配置文件中：

include /etc/nginx/mutnginx/*.conf; 

是在mutnginx目录下，创建了两个跟nginx.conf 相似的文件。

nginx2.conf配置是为了让同个网段即12.17.56.*的其他应用能同个代理ip访问到web工程，其配置如下：

#user  nobody;
worker_processes  auto;

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

}

还有一个nginx3.conf 是为了让，其他内网ip统一访问的代理，其配置如下：

#user  nobody;
worker_processes  auto;

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

#pid        logs/nginx.pid;

}

其中

proxy_set_header Host $host:5123;#是映射端口，如果12.17.56.44:7000映射IP为102.34.56.44 那么5123就是映射器7000端口

这样

12.17.56.44

就被一个互联网IP22.18.55.33:7000 和内网12.17.56.44.：5213以及12.17.56.44:7000做了映射代理，就是这三个ip都能访问到web工程。
