//开启所有节点服务（&是后台运行）：

for i in 79 80 81 82 83 84; do /usr/local/bin/redis-server /usr/local/redis-cluster/63$i/redis.conf& done

//登录随便一个节点验证 确认节点服务可以正常登陆：

/usr/local/redis-cluster/bin/redis-cli -h 192.168.80.102 -p 6379

//查看进程，看有没有6个端口

ps -ef|grep redis|grep cluster

//配置Ruby环境-安装Ruby

yum install -y ruby ruby-devel rubygems rpm-build

gem install redis

报以下错误的话：

Fetching: redis-4.0.1.gem (100%)

ERROR: Error installing redis:

redis requires Ruby version >= 2.2.2.

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

安装rvm工具：

首先安装rvm安装会使用的包

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

安装rvm

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

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

配置rvm的运行环境

source /etc/profile.d/rvm.sh

rvm reload

检查安装情况

rvm requirements run

安装Ruby 2.4.1

rvm install 2.4.1

查看安装结果

rvm use 2.4.1

rvm remove 2.0.0

ruby --version

gem redis接口安装：

gem install redis

rubygems 安装：

yum install -y rubygems

cd /opt/redis-5.0.0/src/

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

创建Redis集群：

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

创建Redis集群

redis-cli -h 192.168.80.102 -c -p 6379

192.168.86.100:6379> cluster info //查看状态

192.168.86.100:6379> cluster nodes //查看节点信息

注：-h+host –p+端口号 –c 连接集群，连接Redis集群必须要加该参数
