#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_namedomain1.com www.domain1.com; 
#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.logmain;

location / { 
indexindex.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

#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_passhttp://127.0.0.1:8080; 
} 
} 

#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 { 
listen80; 
server_name big.server.com; 
access_loglogs/big.server.access.log main; 

location / { 
proxy_passhttp://big_server_com; 
} 
} 
} 

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。
