WordPress

Installation

A simple local setup of Wordpress can be enabled with the following setup

services.wordpress.sites."localhost".enabled = true;

Visit http://localhost to setup your new Wordpress instance. By default, a Mysql server is configured automatically so you won't have to setup the database backend.

Configuration

Plugins and themes

In case you want to package and add custom plugins and themes, you can add these too

let

# For shits and giggles, let's package the responsive theme
responsiveTheme = pkgs.stdenv.mkDerivation {
  name = "responsive-theme";
  # Download the theme from the wordpress site
  src = pkgs.fetchurl {
    url = http://wordpress.org/themes/download/responsive.1.9.7.6.zip;
    sha256 = "06i26xlc5kdnx903b1gfvnysx49fb4kh4pixn89qii3a30fgd8r8";
  };
  # We need unzip to build this package
  buildInputs = [ pkgs.unzip ];
  # Installing simply means copying all files to the output directory
  installPhase = "mkdir -p $out; cp -R * $out/";
};

# Wordpress plugin 'akismet' installation example
akismetPlugin = pkgs.stdenv.mkDerivation {
  name = "akismet-plugin";
  # Download the theme from the wordpress site
  src = pkgs.fetchurl {
    url = https://downloads.wordpress.org/plugin/akismet.3.1.zip;
    sha256 = "1i4k7qyzna08822ncaz5l00wwxkwcdg4j9h3z2g0ay23q640pclg";
  };
  # We need unzip to build this package
  buildInputs = [ pkgs.unzip ];
  # Installing simply means copying all files to the output directory
  installPhase = "mkdir -p $out; cp -R * $out/";
};

in
{
  services.wordpress.sites."webservice5" = {
    themes = [ responsiveTheme ];
    plugins = [ akismetPlugin ];
    virtualHost = {
      adminAddr = "js@lastlog.de";
      serverAliases = [ "webservice5" "www.webservice5" ];
    };
  };
}

Unfortunately you'll have to enable plugins and themes every time you update or install them manually. Hopefully Wordpress plugins and themes will also be packaged inside the Nixpkgs repository, see this draft pull request.

Tips and tricks

Enable SSL behind reverse proxy

In case you're running Wordpress behind a reverse proxy which offers a SSL/https connection to the outside, you can force Wordpress to use the https protocol

services.wordpress.sites."localhost".extraConfig = ''
  // Needed to run behind reverse proxy
  define('FORCE_SSL_ADMIN', true);
  $_SERVER['HTTPS']='on';
'';
