Versions:

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.

Especially be aware of accidental php-execution when extending the configuration.

Caveats about the sample configuration below

  • It does not cover serving securely over HTTPS.
  • It uses the new filesystem layout (with public directory) introduced in version 4.1.0. If your installation has been upgraded to 4.1+ from an older version and you have not upgraded to the public folder, see the version of this documentation for version 4.0.
  • The error pages for 502 (Bad Gateway) and 503 (Service Unavailable) need to be manually created and published in the CMS (assuming use of the silverstripe/errorpage module).
server {
  include mime.types;
  default_type  application/octet-stream;
  client_max_body_size 0; # Manage this in php.ini (upload_max_filesize & post_max_size)
  listen 80;
  root /path/to/ss/folder/public;
  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;

  # See caveats
  error_page 502 /assets/error-500.html;
  error_page 503 /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;
  }
}

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.
