规划、搭建过程：

6个redis实例，一般会放到3台硬件服务器

注：在企业规划中，一个分片的两个分到不同的物理机，防止硬件主机宕机造成的整个分片数据丢失。

端口号：7000-7005

# 1。 安装集群插件

EPEL源安装ruby支持

yum install ruby rubygems -y

# 2. 配置gem源，并安装驱动

gem sources -l

gem sources -a http://mirrors.aliyun.com/rubygems/

gem sources  --remove https://rubygems.org/

gem sources -l

gem install redis -v 3.3.3

# 3. 集群节点准备

# 4. 将节点加入集群管理

redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 \

127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005

# 5.集群状态查看

集群主节点状态

redis-cli -p 7000 cluster nodes | grep master

集群从节点状态

redis-cli -p 7000 cluster nodes | grep slave
