I have an openshift wordpress blog running at http://blog-example.rhcloud.com/ and added CNAME records in my DNS management as follows.
example.com
www.example.com
and works fine. When i type, this leads to my blog home page.But the pages and links in the blog actually leads to openshift naming space. i.e., blog-example.rhcloud.com/?page_id=7
I just want to mask blog-example.rhcloud.com/ to example.com every where in my app.I would be happy to provide further information if any thing required to analyse the issue.
PS: I bought the domain from Big Rock and using their console for CNAME entry.

You need to go to Settings=>General=> Site Address(URL), Settings=>General=> wordpress address(url) and update it to your custom domain.
You need to go into your WordPress admin and change the url on the settings or options page to use your custom domain instead of the app-domain.rhcloud.com one. If you want to change it directly in the database (which i don't recommend) it is in the wp_options table under home and siteurl i believe... But I DO recommend using the WordPress admin.
