Nginx泛解析的匹配域名绑定到子目录配置

网站的目录结构为：

# tree /home/wwwroot/linuxeye.com
/home/wwwroot/linuxeye.com
├── bbs
│   └── index.html
└── www
    └── index.html

2 directories, 2 files

/home/wwwroot/linuxeye.com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.linuxeye.com 访问的就是主页http://bbs.linuxeye.com 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

方法一：

server {
listen 80;
server_name ~^(?<subdomain>.+).linuxeye.com$;
access_log /data/wwwlogs/linuxeye.com_nginx.log combined;
index index.html index.htm index.php;
root /home/wwwroot/linuxeye/$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 *.linuxeye.com;
access_log /home/wwwlogs/linuxeye.com_nginx.log combined;
index index.html index.htm index.php;

if ($host ~* ^([^.]+).([^.]+.[^.]+)$) {
    set $subdomain $1;
    set $domain $2;
}

location / {
    root /home/wwwroot/linuxeye.com/$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;
    }
}
