Redis Enviornment Specific DB's I'm not entirely well versed in how Redis works, but I have an idea that it probably makes the most sense to have the 3 craft sites I have running on the same server, have 3 different redis databases assigned to each?

Is there a way to do so, like in general.php or db.php

As in 

"site-one.com" =&gt; {
    'database' =&gt; 0,
},

"site-two.com" =&gt; {
    'database =&gt; 1,
}
You'll want to set your cacheMethod config setting to 'redis' and create a rediscache.php file in craft/config/.

That config file is multi-environment aware, just like the other files in craft/config/ and you can see the default settings for Redis in craft/app/etc/config/defaults/rediscache.php.
