- One minute read - 170 wordswww.s135.com 和 blog.s135.com 域名均指向 Nginx 所在的服务器IP。
用户访问 http://www.s135.com,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 http://blog.s135.com, 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:

附:Nginx 的安装方法可参照《 Nginx 0.5.31 + PHP 5.2.4(FastCGI)搭建可承受3万以上并发连接数,胜过Apache 10倍的Web服务器》文章的以下段落(仅做负载均衡,无需支持PHP的安装方法):
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
