WordPress Heroku

This project is a template for installing and running WordPress on Heroku. The repository comes bundled with PostgreSQL for WordPress and WP Read-Only.

Installation

Clone the repository from Github

$ git clone git://github.com/mhoofman/wordpress-heroku.git

With the Heroku gem, create your app

$ cd wordpress-heroku
$ heroku create
> Creating strange-turtle-1234... done, stack is cedar
> http://strange-turtle-1234.herokuapp.com/ | [email protected]:strange-turtle-1234.git
> Git remote heroku added

Add a database to your app

$ heroku addons:add heroku-postgresql:dev
> Adding heroku-postgresql:dev to strange-turtle-1234... done, v2 (free)
> Attached as HEROKU_POSTGRESQL_COLOR
> Database has been created and is available
> Use `heroku addons:docs heroku-postgresql:dev` to view documentation

Promote the database (replace COLOR with the color name from the above output)

$ heroku pg:promote HEROKU_POSTGRESQL_COLOR
> Promoting HEROKU_POSTGRESQL_COLOR to DATABASE_URL... done

Create a new branch for any configuration/setup changes needed

$ git checkout -b production

Copy the wp-config.php

$ cp wp-config-sample.php wp-config.php

Update unique keys and salts in wp-config.php on lines 48-55. Wordpress can provide random values here.

define('AUTH_KEY',         'put your unique phrase here');
define('SECURE_AUTH_KEY',  'put your unique phrase here');
define('LOGGED_IN_KEY',    'put your unique phrase here');
define('NONCE_KEY',        'put your unique phrase here');
define('AUTH_SALT',        'put your unique phrase here');
define('SECURE_AUTH_SALT', 'put your unique phrase here');
define('LOGGED_IN_SALT',   'put your unique phrase here');
define('NONCE_SALT',       'put your unique phrase here');

Clear .gitignore and commit wp-config.php

$ >.gitignore
$ git add .
$ git commit -m "Initial WordPress commit"

Deploy to Heroku

$ git push heroku production:master
> -----> Heroku receiving push
> -----> PHP app detected
> -----> Bundling Apache v2.2.22
> -----> Bundling PHP v5.3.10
> -----> Discovering process types
>        Procfile declares types -> (none)
>        Default types for PHP   -> web

>        http://strange-turtle-1234.herokuapp.com deployed to Heroku
>
> To git@heroku:strange-turtle-1234.git
> * [new branch]    production -> master

After deployment WordPress has a few more steps to setup and thats it!

Usage

Because a file cannot be written to Heroku's file system, updating and installing plugins or themes should be done locally and then pushed to Heroku.

Updating

Updating your WordPress version is just a matter of merging the updates into the branch created from the installation.

$ git pull # Get the latest

Using the same branch name from our installation:

$ git checkout production
$ git merge master # Merge latest
$ git push heroku production:master

WordPress needs to update the database. After push, navigate to:

http://your-app-url.herokuapp.com/wp-admin

WordPress will prompt for updating the database. After that you'll be good to go.
