redis5.0 later set up a cluster

Why ruby ​​redis5.0 before?

Because there is a file redis-trib.rb in redis / src in, is written in Ruby, used to build redis clusters (redis3.0 version only began to support clusters), so I want to build a cluster need to have a redis execution. rb for Ruby runtime environment.

Meanwhile ruby ​​operation are also dependent redis.gem this file.

So before building 5.0 cluster environment need to install ruby, gem download files.
