www.haohtml.com 和 blog.haohtml.com 域名均指向 Nginx 所在的服务器IP。

用户访问，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，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：引用 user www www;

worker_processes 10;

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

#pid logs/nginx.pid;

#最大文件描述符 worker_rlimit_nofile 51200;

events { use epoll;

worker_connections 51200; }

http { include conf/mime.types; default_type application/octet-stream;

keepalive_timeout 120;

tcp_nodelay on;

upstream www.haohtml.com { server 192.168.1.2:80; server 192.168.1.3:80; server 192.168.1.4:80; server 192.168.1.5:80; }

upstream blog.haohtml.com { server 192.168.1.7:8080; server 192.168.1.7:8081; server 192.168.1.7:8082; }

server { listen 80; server_name www.haohtml.com;

location / { proxy_pass ; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }

log_format www_haohtml_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_haohtml_com; }

server { listen 80; server_name blog.haohtml.com;

location / { proxy_pass ; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }

log_format blog_haohtml_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/blog.log blog_haohtml_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
