Nginx是一款轻量级的Web 服务器/反向代理服务器及电子邮件（IMAP/POP3）代理服务器

反向代理（Reverse Proxy）方式是指以代理服务器来接受internet上的连接请求，然后将请求转发给内部网络上的服务器，并将从服务器上得到的结果返回给internet上请求连接的客户端，此时代理服务器对外就表现为一个服务器。

源码安装：

准备：sudo apt-get install libpcre3 libpcre3-dev libssl-dev openssl zlib1g-dev在源码安装的时候,需要安装编译环境sudo apt-get install libtoolsudo apt-get install gcc-c++sudo apt-get install build-essentialsudo apt-get updatesudo apt-get upgradesudo apt-get install gcc-c++开始安装pcrewget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gztar zxvf pcre-8.35.tar.gzcd pcre-8.35./configuresudo make && sudo make install或者直接安装pcresudo apt-get install -y libpcre3 libpcre3-dev zlib1g-devpcre-config --version安装nginxwget http://nginx.org/download/nginx-1.6.2.tar.gztar zxvf nginx-1.6.2.tar.gzcd nginx-1.6.2./configuresudo make && sudo make install/usr/local/nginx/sbin/nginx -v创建 Nginx 运行使用的用户:www密码:www：groupadd www useradd -g www www备份cd  /usr/local/nginx/conf/cp nginx.conf nginx_old.conf配置nginx.conf ，将/usr/local/nginx/conf/nginx.conf替换为以下内容gedit /usr/local/nginx/conf/nginx.conf测试配置是否成功/usr/local/nginx/sbin/nginx -t启动nginxsudo /usr/local/nginx/sbin/nginx浏览器打开http://127.0.0.1:8888/Nginx 其他命令/usr/local/nginx/sbin/nginx -s reload            # 重新载入配置文件/usr/local/nginx/sbin/nginx -s reopen            # 重启 Nginx/usr/local/nginx/sbin/nginx -s stop              # 停止 Nginx

IP端口转发 代理配置：

    upstream es.com {        server 127.0.0.1:9200;     }     server {          listen 9999;          server_name localhost:9200;          location / {              proxy_pass http://es.com;              proxy_set_header  X-Real-IP  $remote_addr;              proxy_set_header Host $host;          }     } #端口转发 http://my.oschina.net/kear/blog/109868upstream 131.com {        server 192.168.1.131:9200;     }     server {          listen 7777;           location / {              proxy_pass http://131.com;              proxy_set_header  X-Real-IP  $remote_addr;              proxy_set_header Host $host;          }     }
