Nginx

These instructions are also covered on the Nginx Wiki.

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 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 when extending the configuration.

But enough of the disclaimer, on to the actual configuration — typically in nginx.conf:

server {
  include mime.types;
  default_type  application/octet-stream;
  client_max_body_size 0; # Manage this in php.ini
  listen 80;
  root /path/to/ss/folder;
  server_name example.com www.example.com;

  # Defend against SS-2015-013 -- http://www.silverstripe.org/software/download/security-releases/ss-2015-013
  if ($http_x_forwarded_host) {
    return 400;
  }

  location / {
      try_files $uri /index.php?$query_string;
  }

  error_page 404 /assets/error-404.html;
  error_page 500 /assets/error-500.html;

  location ^~ /assets/ {
    sendfile on;
    try_files $uri =404;
  }

  location /index.php {
    fastcgi_buffer_size 32k;
    fastcgi_busy_buffers_size 64k;
    fastcgi_buffers 4 32k;
    fastcgi_keep_conn on;
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include        fastcgi_params;
  }

  # Denials
  location ~ /\.. {
    deny all;
  }
  location ~ \.ss$ {
    satisfy any;
    allow 127.0.0.1;
    deny all;
  }
  location ~ web\.config$ {
    deny all;
  }
  location ~ \.ya?ml$ {
    deny all;
  }
  location ~* README.*$ {
    deny all;
  }
  location ^~ /vendor/ {
    deny all;
  }
  location ~* /silverstripe-cache/ {
    deny all;
  }
  location ~* composer\.(json|lock)$ {
    deny all;
  }
  location ~* /(cms|framework)/silverstripe_version$ {
    deny all;
  }
}

The above configuration sets up a virtual host example.com with rewrite rules suited for SilverStripe. The location block for index.php passes the php script to the FastCGI-wrapper via a TCP socket.

Now you can proceed with the SilverStripe installation normally.
