简介

redis-trib.rb是官方提供的Redis Cluster的管理工具,无需额外下载,默认位于源码包的src目录下,但因该工具是用ruby开发的,所以需要准备相关的依赖环境

准备redis-trib.rb的运行环境

wget https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.1.tar.gz

tar xvf ruby-2.5.1.tar.gz

cd ruby-2.5.1/

./configure -prefix=/usr/local/ruby

make

make install

cd /usr/local/ruby/

cp bin/ruby /usr/local/bin

cp bin/gem /usr/local/bin

安装rubygem redis依赖

wget http://rubygems.org/downloads/redis-3.3.0.gem

gem install -l redis-3.3.0.gem
