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 ~^(?.+).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;
}
}
