搭建Nginx四层反向代理

需求背景：

前段时间公司因为业务需求需要部署一个正向代理，我已经分享出来了https://www.cnblogs.com/Dfengshuo/p/11911406.html，现有因架构个更改，需要再加个在原先的反向代理下再加一层，ok，其实还是挺鸡肋的，但是没办法，领导安排就要根据安排需求做。其实nginx反向代理分两种，四层网络层代理和七层应用层代理，想要实现这两种模式很简单，只是配置文件略微不同而已。今天分享一下四层协议的代理吧！

首先安装nginx环境：

1 yum -y install pcre-devel zlib-devel gcc gcc+c++ make openssl openssl-devel
2 tar xf nginx-1.11.4.tar.gz
3 cd nginx-1.11.4/
4  ./configure --prefix=/usr/local/nginx  --with-http_stub_status_module --with-http_gzip_static_module --with-http_ssl_module --with-http_stub_status_module --with-pcre --with-stream && make && make install

编译安装完毕后进行更改nginx配置文件，配置四层协议反向代理

#user  nobody;
worker_processes  1;

#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;
}


--------------------------反向配置区------------------------------------------
stream {

server {

listen 30010;                #监听端口

proxy_connect_timeout 1s;

proxy_timeout 3s;

proxy_pass 10.157.8.18:30010;    #跳转地址

}

server {

listen 30013;

proxy_connect_timeout 1s;

proxy_timeout 3s;

proxy_pass 10.157.8.18:30013;

}




server {

listen 30014;

proxy_connect_timeout 1s;

proxy_timeout 3s;

proxy_pass 10.157.8.18:30014;

}


}

--------------------------反向配置区------------------------------------------

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;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }
    
    }   

}

　配置完成后保存重启nginx即可，进行测试，结果表明成功！
