Nginx配置负载均衡

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

用户访问http://www.guangzhouhr.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.guangzhouhr.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;

#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;
