Create a ruby application (ruby-1.8 or ruby-1.9)
rhc app create -a redmine -t ruby-1.9 # or ruby-1.8
Add mysql support to your application
rhc app cartridge add -a redmine -c mysql-5.1
Make a note of the username, password, and host name as you will need to use these to login to the mysql database

cd redmine
git remote add upstream -m master git://github.com/openshift/redmine-2.0-openshift-quickstart.git
git pull -s recursive -X theirs upstream master
In order to be able to upload files attached to issues, you should add a "files" directory/folder
mkdir files
and remove the line /files/* from .gitignore to push that directory/folder to all the gears (where your OpenShift application is running).
Alternatively, you can ssh to all the serving gears for your application and create a directory/folder called "files" under redmine/repo
mkdir redmine/repo/files
Then push the repo upstream
git push
That's it, you can now checkout your application at:
http://redmine-$yournamespace.rhcloud.com
Use the following to login to your new Redmine application running on OpenShift:
username: admin
password: admin
Once your installation is complete, it is highly recommended that you change the password for the Redmine admin user - see the Change password link at:
