openshift environment variables

you can find out your openshift mysql host, openshift mysql user and openshift mysql password by looking at your openshift environment variables

  • $ ssh myopenshiftuser@myopenshiftdomain
  • $ env | grep OPENSHIFT
more information on environment variables

OpenShift provides several environment variables to reference for ease of use.

The following list are some common variables but far from exhaustive:

$_ENV[‘OPENSHIFT_APP_NAME’] – Application name
$_ENV[‘OPENSHIFT_GEAR_DIR’] – Application dir
$_ENV[‘OPENSHIFT_DATA_DIR’] – For persistent storage (between pushes)
$_ENV[‘OPENSHIFT_TMP_DIR’] – Temp storage (unmodified files deleted after 10 days)

When embedding a database using ‘rhc app cartridge add’, you can reference environment variables for username, host and password:

$_ENV[‘OPENSHIFT_DB_HOST’] – DB host
$_ENV[‘OPENSHIFT_DB_PORT’] – DB Port
$_ENV[‘OPENSHIFT_DB_USERNAME’] – DB Username
$_ENV[‘OPENSHIFT_DB_PASSWORD’] – DB Password

and you can use these in your drupal, wikkawiki, wordpress config file as follows


/** The name of the database for your lamp app */
define('DB_NAME', $_ENV['OPENSHIFT_APP_NAME']);
/** MySQL database username */
define('DB_USER', $_ENV['OPENSHIFT_DB_USERNAME']);
/** MySQL database password */
define('DB_PASSWORD', $_ENV['OPENSHIFT_DB_PASSWORD']);
/** MySQL hostname */
define('DB_HOST', $_ENV['OPENSHIFT_DB_HOST']);

your actual php code can be found in ~/app-root/runtime/repo/php

more openshift repo layout info

Repo layout
===========
php/ – Externally exposed php code goes here
libs/ – Additional libraries
misc/ – For not-externally exposed php code
../data – For persistent data (full path in environment var: OPENSHIFT_DATA_DIR)
deplist.txt – list of pears to install
.openshift/action_hooks/pre_build – Script that gets run every git push before the build
.openshift/action_hooks/build – Script that gets run every git push as part of the build process (on the CI system if available)
.openshift/action_hooks/deploy – Script that gets run every git push after build but before the app is restarted
.openshift/action_hooks/post_deploy – Script that gets run every git push after the app is restarted
Notes about layout
==================
Please leave php, libs and data directories but feel free to create additional directories if needed.
Note: Every time you push, everything in your remote repo dir gets recreated please store long term items (like an sqlite database) in ../data which will persist between pushes of your repo.
