Add Redis to OpenShift PaaS

We can run Redis on OpenShift using downloadable cartridge and also we can work with Redis CLI on OpenShift, which is the standard for Redis. There are at least two different OpenShift Redis Cartridge available, developed by individuals. We are providing three important links which are related to Redis and basically they were basically intended for using Redis Cache with WordPress on Cloud Server – Plugins Needed to Get Fast WordPress with Redis; Redis Cache, WordPress and Cloud Server; Load WordPress Faster with Redis on Rackspace Cloud Server.

As we have said; there are at least two known OpenShift cartage exists for Redis :

The first one is less complicated while the second one is scalable and can offer more redundancy. Second one can not be used in free accounts with WordPress because simply if we use two gears for Redis only, we have to use one gear for WordPress, which is not desired – MySQL should be at different gear. Technically, the first one solves the basic need. We are providing a basic example for adding Redis to WordPress – it is probable to get problem with both of them in long run. Other stuffs can be read from our linked guides for Redis.
Redis is also available from OpenShift MarketPlace.
