需求：由于购买了云上主机，只有一台跳板机有外网网卡，通过nginx反向代理实现内部服务器上网

1. 下载nginx  网址http://nginx.org/download/

 2. 解压压缩包nginx-1.16.1.tar.gz

tar -xf nginx-1.16.1.tar.gz

3.编译安装

cd /data/nginx-1.16
./configure --prefix=/data/nginx --with-http_stub_status_module --with-http_ssl_module --with-stream --with-http_sub_module --with-http_gzip_static_module

4. 下载环境

yum -y install gcc gcc-c++ autoconf automake make
yum install pcre -y
yum install pcre-devel -y 
yum install -y zlib
yum install -y zlib-devel

5. 安装

make && make install

6.正向代理配置

    server {  
        resolver 114.114.114.114;       #指定DNS服务器IP地址  
        listen 80;  
        proxy_connect;
        proxy_connect_allow            443 563;
        proxy_connect_connect_timeout  10s;
        proxy_connect_read_timeout     10s;
        proxy_connect_send_timeout     10s;
         access_log  logs/https.log  main;
        location / {
            proxy_pass http://$host;
            proxy_set_header Host $host;
        }
    }
  

7. 客户机测试

curl -i  --proxy 172.16.20.20:80 www.4399.com

8.配置yum

vim /etc/yum.conf
proxy = http://172.16.20.20:80/
