Nginx 简单的负载均衡配置示例
用户访问http://www.net-hb.com.cn,将其负载均衡到192.168.1.2:80、192.168.1.3:80、192.168.1.4:80、192.168.1.5:80四台服务器。
用户访问//www.jb51.net,将其负载均衡到192.168.1.7服务器的8080、8081、8082端口。
以下为配置文件nginx.conf:

二、安装PHP 5.2.4(FastCGI模式)
4、创建www用户和组,以及其使用的目录:
三、安装Nginx 0.5.31
1、安装Nginx所需的pcre库:
2、安装Nginx
3、创建Nginx日志目录
5、启动Nginx
