nginx将泛解析的匹配域名绑定到子目录配置方法
网站的目录结构为:
	 # tree /home/wwwroot/exehack.net
	/home/wwwroot/exehack.net
	├── bbs
	│   └── index.html
	└── www
	    └── index.html
	2 directories, 2 files
	/home/wwwroot/exehack.net为nginx的安装目录下默认的存放源代码的路径。
	bbs为论坛程序源代码路径;www为主页程序源代码路径;把相应程序放入上面的路径通过;http://www.exehack.net 访问的就是主页http://bbs.exehack.net 访问的就是论坛,其它二级域名类推。
	有2种方法,推荐方法一
 server {
listen 80;
server_name ~^(?<subdomain>.+).exehack.net$;
access_log /data/wwwlogs/exehack.net_nginx.log combined;
index index.html index.htm index.php;
root /home/wwwroot/linuxeye/$subdomain/;
location ~ .php$ {
  fastcgi_pass unix:/dev/shm/php-cgi.sock;
  fastcgi_index index.php;
  fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  include fastcgi_params;
  }
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
  expires 30d;
  }
location ~ .*\.(js|css)?$ {
  expires 7d;
  }
}
方法二、
 server {
listen 80;
server_name *.exehack.net;
access_log /home/wwwlogs/exehack.net_nginx.log combined;
index index.html index.htm index.php;
if ($host ~* ^([^\.]+)\.([^\.]+\.[^\.]+)$) {
  set $subdomain $1;
  set $domain $2;
}
location / {
  root /home/wwwroot/exehack.net/$subdomain/;
  index index.php index.html index.htm;
}
location ~ .php$ {
  fastcgi_pass unix:/dev/shm/php-cgi.sock;
  fastcgi_index index.php;
  fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  include fastcgi_params;
  }
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
  expires 30d;
  }
location ~ .*\.(js|css)?$ {
  expires 7d;
  }
}
nginx将泛解析的匹配域名绑定到子目录的配置方法如下
		
		server {
		    listen        80;
		    server_name   domain.com    *.domain.com;
		    if ($host ~* ^([^\.]+)\.([^\.]+\.[^\.]+)$) {
		        set $subdomain $1;
		        set $domain $2;
		    }
		    location / {
		        root    /home/wwwroot/$domain/$subdomain/;
		        index   index.php index.html index.htm;
		        #include /home/wwwroot/$domain/$subdomain/.ngx.htaccess;
		    }
error_page 500 502 503 504 /50x.html;
		    location = /50x.html {
		        root   html;
		    }
		    location ~ \.php$ {
		        root           /home/wwwroot/$domain/$subdomain/;
		        fastcgi_pass   127.0.0.1:9100;
		        fastcgi_index  index.php;
		        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
		        include        fastcgi_params;
		    }
		}
