Is it possible to host 2 redis databases on the same linux server?

The reason why there is 2 redis dbs, is because the client we support Redis for has two environments. So each of the redis dbs have different data on.

I know that I can build another linux box and host it from there too, but the company wants to save costs.

This is kind of the flow I need.

Environment 1 -> Redis Server -> Redis db 1
Environment 2 -> Redis Server -> Redis db 2

The only dilemma is, how do you distinguish what database you want each environment to use?

Thanks,

Dan
