   #反向代理配置，可以打开proxy.conf看看
   include /etc/nginx/proxy.conf;

   include /etc/nginx/fastcgi.conf;
   default_type application/octet-stream;
   #日志的格式

   access_log logs/access.log main;
   sendfile on;
   tcp_nopush on;
   #根据实际情况调整，如果server很多，就调大一点
   server_names_hash_bucket_size 128; # this seems to be required for some vhosts
   #这个例子是fastcgi的例子，如果用fastcgi就要仔细看
   server { 
      # php/fastcgi
      listen 80;
      #域名，可以有多个
      server_name domain1.com www.domain1.com; &nbs…
      #访问日志，和上面的级别不一样，应该是下级的覆盖上级的
      access_log logs/domain1.access.log main;
      root html;
      location / {
         index index.html index.htm index.php;
      }
      #所有php后缀的，都通过fastcgi发送到1025端口上
      #上面include的fastcgi.conf在此应该是有作用，如果你不include，那么就把fastcgi.conf的配置项放在这个下面。
      location ~ /.php$ {
         fastcgi_pass 127.0.0.1:1025;
      }
   }
   #这个是反向代理的例子
   server { # simple reverse-proxy
      listen 80;
      server_name domain2.com www.domain2.com; &nbs…
      access_log logs/domain2.access.log main;
      #静态文件，nginx自己处理
      location ~ ^/(images|javascript|js|css|flash|media|static)/ {
        root /var/www/virtual/big.server.com/htdocs;
         #过期30天，静态文件不怎么更新，过期可以设大一点，如果频繁更新，则可以设置得小一点。
         expires 30d;
      }
      #把请求转发给后台web服务器，反向代理和fastcgi的区别是，反向代理后面是web服务器，fastcgi后台是fasstcgi监听进程，当然，协议也不一样。
      location / {
         proxy_pass http://127.0.0.1:8080;&nbs…
      }
   }
   #upstream的负载均衡，weight是权重，可以根据机器配置定义权重。据说nginx可以根据后台响应时间调整。后台需要多个web服务器。
   upstream big_server_com {
      server 127.0.0.3:8000 weight=5;
      server 127.0.0.3:8001 weight=5;
      server 192.168.0.1:8000;
      server 192.168.0.1:8001;
   }
   server {
      listen 80;
      server_name big.server.com;
      access_log logs/big.server.access.log main;
      location / {
         proxy_pass http://big_server_com;&nbs…
      }
   }
}

上面说的include的几个文件，都没有必要改，用的时候include一下就可以。

更多的，每个项的具体含义和配置选择，可以参考如下：
http://wiki.codemongers.co…
可以依次从MainModule,Events Module,Http Core Module,Http UpStream Module的顺序看。
关于配置和模块的关系是，装了什么模块，就可以用到什么配置，因此配置是灵活多变的
