How to enable mod rewrite for drupal site on ISPConfig 3 nginx

Hi all,

I have several sites running Drupal and Joomla on LAMP, and I'm trying to migrate these sites to LEMP with ISPConfig 3. I can get to the index page, but I don't know which rewrite rules to apply to a site.

I have tried

Code:

if ($http_host != "site.example.com") {
rewrite ^ http://site.example.com$request_uri permanent;
}

but it does not work. However, this require rule worked when I install LEMP without ISPConfig.

Any helps will be appreciated.

Thanks,
Anh
