Bluehost的控制管理真是相当麻烦就拿域名与ftp目录对应的关系来说，都够头疼的，而且主域名也就是购买时候的域名竟然是/public_html/ 这个目录，也就是他是所有后添加网站的目录的上一层目录. 很显然，如果这个样的话 这个主域名怎么用啊，这样的话，子目录下的那些站点都成为主域名的副站点了.想象bluehsot控制面板管理真是人性化，结果寻找终于找到怎么绑定任意目录的方法了.是修改.htaccess,规则如下：
# Bluehost.com
# .htaccess main domain to subfolder redirect
# Copy and paste the following code into the .htaccess file
# in the public_html folder of your hosting account
# make the changes to the file according to the instructions.
# Do not change this line.
RewriteEngine on
# Change yourdomain.com to be your main domain.
RewriteCond %{HTTP_HOST} ^(www.)?yourmaindomain.com$
# Change ’subfolder’ to be the folder you will use for your main domain.
RewriteCond %{REQUEST_URI} !^/subfolder/
# Don’t change this line.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Change ’subfolder’ to be the folder you will use for your main domain.
RewriteRule ^(.*)$ /subfolder/$1
# Change yourdomain.com to be your main domain again.
# Change ’subfolder’ to be the folder you will use for your main domain
# followed by / then the main file for your site, index.php, index.html, etc.
RewriteCond %{HTTP_HOST} ^(www.)?yourmaindomain.com$
RewriteRule ^(/)?$ subfolder/index.php [L]
备注：subfolder替换你在public_html/下建立的目录,yourmaindomain.com替换为你的域名
