Source code for my blog, avaliable at lexev.org and hosted on openshift cloud

It is build with python 2.7, django, mysql.

Runtime Configuration (thanks to openshift-diy-py27-django example, most install sequence i've got from there)

Create a new OpenShift app:

  • rhc-create-app -a <app_name> -t diy-0.1

Add mysql, phpmyadmin, cron cartridges:

  • rhc-ctl-app -a <app_name> -e add-mysql-5.1
  • rhc-ctl-app -a <app_name> -e add-phpmyadmin-3.4
  • rhc-ctl-app -a <app_name> -e add-cron-1.4

Login to the application host using the credentials from the above command. It will look like ssh://c8812345:123214@<app_name>-username.rhcloud.com:

  • ssh c8812345:123214@<app_name>-username.rhcloud.com

Change into the application tmp directory:

  • cd $OPENSHIFT_TMP_DIR

Download Python2.7 and extract:

  • wget http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2
  • tar jxf Python-2.7.3.tar.bz2

Build and install Python

  • cd Python-2.7.3
  • ./configure --prefix=$OPENSHIFT_REPO_DIR/../
  • make ; make install

Export new Python path for later configuration (you will need to run this if you logout, etc.):

  • export PATH=$OPENSHIFT_REPO_DIR/../bin:$PATH

Check that new Python is used (should be Python 2.7.3):

  • python -V

Install setuptools and pip

  • cd $OPENSHIFT_TMP_DIR
  • wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz
  • tar zxf setuptools-0.6c11.tar.gz
  • cd setuptools-0.6c11
  • python setup.py install
  • cd $OPENSHIFT_TMP_DIR
  • wget http://pypi.python.org/packages/source/p/pip/pip-1.1.tar.gz
  • tar zxf pip-1.1.tar.gz
  • cd pip-1.1
  • python setup.py install

Install uWSGI

  • cd $OPENSHIFT_TMP_DIR
  • pip install uwsgi

Install MySQL-python

  • cd $OPENSHIFT_TMP_DIR
  • pip install MySQL-python

Cleanup

  • cd ~
  • rm -rf $OPENSHIFT_TMP_DIR/*

Application Setup

Clone / Fork this repo.

Add an upstream to OpenShift:

  • Get the Git URL from rhc app show -a <app_name>
  • git remote add openshift <GIT_URL_from_above>
  • git push openshift master

Note: you may get an error during the git push to openshift saying the repo is not in sync. If you don't have any changes in the OpenShift repo, you can force the push with:

git push -f openshift master

Useful commands

* Note

If you change the Django application name (in the repo it's named myblog) you will also need to update the .app_name file with the new name in order for the OpenShift start/stop scripts to work.
