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
創建Redis集羣：
redis-trib.rb create --replicas 1 192.168.80.102:6379 192.168.80.102:6380 192.168.80.102:6381 192.168.80.102:6382 192.168.80.102:6383 192.168.80.102:6384
redis-cli --cluster create 192.168.80.102:6379 192.168.80.102:6380 192.168.80.102:6381 192.168.80.102:6382 192.168.80.102:6383 192.168.80.102:6384 --cluster-replicas 1
創建Redis集羣
redis-cli -h 192.168.80.102 -c -p 6379
192.168.86.100:6379> cluster info //查看狀態
192.168.86.100:6379> cluster nodes //查看節點信息
注：-h+host –p+端口號 –c 連接集羣，連接Redis集羣必須要加該參數
