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

代码如下:
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/;
