上节主要演示了redis单节点的安装部署，对于数据量更大的服务可以安装redis-cluster进行处理
1. 安装ruby
yum install ruby ruby-devel rubygems rpm-build -y
rpm -qa|grep ruby
ruby -v
2.安装redis-cluster
gem install redis --version 3.2.
gem list
3.到redis源码目录找到集群创建工具
/bin/cp /server/tools/redis-3.2./src/redis-trib.rb /usr/local/redis/bin/
4.创建redis-cluster集群节点
(1)创建节点目录，修改配置文件
[root@redis-server tools]# mkdir -p /usr/local/redis/redis-cluster/{7001,7002,7003}
cluster-enabled yes
cluster-config-file /usr/local/redis/redis-cluster//nodes-.conf
cluster-node-timeout
appendonly yes
[root@redis-server tools]# sh -x add_redis-cluster-port_rc.sh
+ echo '------ Start Create redis-cluster ------'

+ redisport2=
+ redisport3=
