Cluster Configuration using the Ruby script
Redis Cluster can be configured manually or through a Redis Cluster command line utility called redis-trib.
In order to run redis-trib you need to install Ruby and the Redis client for Ruby first.
Download the Ruby installer from here. During the installation select the following checkboxes:
- Add Ruby executables to your PATH
- Associate .rb and .rbw files with this Ruby installation
After Ruby has been installed, you need to install the Redis client package for Ruby:
- open a Command Prompt window and type
gem install redis
The gem package manager will add the redis-3.2.1.gem package to your Ruby installation.
Follow the official Redis Cluster Tutorial to learn how to use the redis-trib utility.
