The prerequisite is that you have already installed Nginx and you are
able to run PHP files via the FastCGI-wrapper from Nginx.
Now you need to set up a virtual host in Nginx with the following
configuration settings:
Now you need to set up a virtual host in Nginx with configuration settings
that are similar to those shown below.

If you don't fully understand the configuration presented here, consult the
[nginx documentation](http://nginx.org/en/docs/).
Especially be aware of [accidental php-execution](https://nealpoole.com/blog/2011/04/setting-up-php-fastcgi-and-nginx-dont-trust-the-tutorials-check-your-configuration/ "Don't trust the tutorials") when extending the configuration.

With only the above configuration, nginx would hand out any existing file
uninterpreted, so it would happily serve your precious configuration files,
including all your private api-keys and whatnot to any random visitor. So you
**must** restrict access further.

You don't need to use separate files, but it is easier to have the permissive
rules distinct from the restricting ones.
Here is the include file `htaccess`:

The above configuration sets up a virtual host `example.com` with
rewrite rules suited for SilverStripe. The location block named
`@silverstripe` passes all php scripts to the FastCGI-wrapper via a Unix
socket. This example is from a site running Ubuntu with the php5-fpm
package.
`@silverstripe` passes all requests that aren't matched by one of the other
location rules (and cannot be satisfied by serving an existing file) to
SilverStripe framework's main.php script, that is run by the FastCGI-wrapper,
that in turn is accessed via a Unix socket.
Now you can proceed with the SilverStripe installation normally.
