Nginx (engine x) 是一个高性能的HTTP和反向代理web服务器，同时也提供了IMAP/POP3/SMTP服务。Nginx是由伊戈尔·赛索耶夫为俄罗斯访问量第二的Rambler.ru站点（俄文：Рамблер）开发的，第一个公开版本0.1.0发布于2004年10月4日。
其将源代码以类BSD许可证的形式发布，因它的稳定性、丰富的功能集、简单的配置文件和低系统资源的消耗而闻名。2011年6月1日，nginx 1.0.4发布。
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，在BSD-like 协议下发行。其特点是占有内存少，并发能力强，事实上nginx的并发能力在同类型的网页服务器中表现较好，中国大陆使用nginx网站用户有：百度、京东、新浪、网易、腾讯、淘宝等。
Nginx一般作为tomcat负载均衡较多，使用其代理其它功能的比较少，也很难找到相关资料。
本文简单说明一下，Nginx还可以代理各类数据库、TCP连接
1、代理数据库，配置conf文件
增加stream模块
stream {
upstream sqlserver_cyj {
server 192.168.1.195:1433;
}
server {
listen 1521;
proxy_pass oracle_1521_93;
proxy_connect_timeout 10s;
proxy_timeout 36000s;
}
}
代理TCP链接
events {
worker_connections 1024;
}
增加stream模块
stream {
upstream sqlserver_cyj {
server 192.168.1.195:1024;
}
server {
listen 1024;
proxy_pass sqlserver_cyj ;
proxy_connect_timeout 10s;
proxy_timeout 36000s;
}
}
nginx.conf 配置文件
#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;
}
stream {
