Nginx 简单的负载均衡配置示例

www.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:

user www www;

worker_processes 10;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

{
use epoll;

worker_connections 51200;
}

http
{

default_type application/octet-stream;

}

upstream blog.s135.com {

proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

log_format www_s135_com '$remote_addr - $remote_user [$time_local] $request '
'"$status" $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /data1/logs/www.log www_s135_com;
}

}

log_format blog_s135_com '$remote_addr - $remote_user [$time_local] $request '

'"$http_user_agent" "$http_x_forwarded_for"';
access_log /data1/logs/blog.log blog_s135_com;
}
}


  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
  3、创建Nginx日志目录
  5、启动Nginx
