報以下錯誤的話：

Fetching: redis-4.0.1.gem (100%)

ERROR: Error installing redis:

redis requires Ruby version >= 2.2.2.

注意：redis-trib.rb的運行需要的ruby包，Ruby版本至少需要2.2.2

安裝rvm工具：

首先安裝rvm安裝會使用的包

yum install gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison iconv-devel sqlite-devel

安裝rvm

curl -sSL https://rvm.io/pkuczynski.asc | gpg2 –import –

curl -L get.rvm.io | bash -s stable

配置rvm的運行環(huán)境

source /etc/profile.d/rvm.sh

rvm reload

檢查安裝情況

rvm requirements run

安裝Ruby 2.4.1

rvm install 2.4.1

查看安裝結(jié)果

rvm use 2.4.1

rvm remove 2.0.0

ruby –version

gem redis接口安裝：

gem install redis

rubygems 安裝：

yum install -y rubygems

cd /opt/redis-5.0.0/src/

cp redis-trib.rb /usr/local/bin

創(chuàng)建Redis集群

redis-cli -h 192.168.80.102 -c -p 6379

192.168.86.100:6379> cluster info //查看狀態(tài)

192.168.86.100:6379> cluster nodes //查看節(jié)點信息

注：-h+host –p+端口號 –c 連接集群，連接Redis集群必須要加該參數(shù)
