节点信息规划
本来只准备部署7001-7004 4个实例，但是redis集群提示最少需要3个主节点，6个节点才能完成启动，所以后面2个是后来加的。
注意：这里因为是测试环境，所以将所有实例都放在了一台机器上，生产建议主备节点不要放在一台机器上

环境安装(按照正常安装步骤，碰到问题再解决)
1.下载redis-4.0.1.tar.gz源码包
[root@elk01 opt]# wget http://download.redis.io/releases/redis-4.0.1.tar.gz --2017-10-26 09:33:23-- http://download.redis.io/releases/redis-4.0.1.tar.gz Resolving download.redis.io (download.redis.io)... 109.74.203.151 Connecting to download.redis.io (download.redis.io)|109.74.203.151|:80... connected.

3.配置redis集群文件
[root@elk01 redis-4.0.1]# mkdir redis-cluster
You have mail in /var/spool/mail/root
[root@elk01 redis-4.0.1]# mkdir redis-cluster/nodes-{7001,7002,7003,7004}

4.启动redis及创建集群
依次启动各个redis实例
#启动redis实例
[root@elk01 redis-cluster]# redis-server /opt/redis-cluster/nodes-7002/redis.conf
[root@elk01 redis-cluster]# ll nodes-7002/ #里面新增了一些文件

#创建redis集群
创建redis集群使用redis-trib.rb命令，该命令是基于ruby的脚本，需要安装ruby，ruby-gem以及gem-redis
[root@elk01 redis-cluster]# redis-trib.rb create --replicas 1 192.168.9.216:7001 192.168.9.216:7002 192.168.9.216:7003 192.168.9.216:7004

推荐：如果默认国外的gem源连不上或者很慢，可以试试国内源
添加国内源命令：gem source -a https://gems.ruby-china.org
删除国外源并添加国内源：gem sources --add https://gems.ruby-china.org/ --remove https://rubygems.org/
#检测gem源，注意RubyGems源尽量用新版本，官方建议2.6.X，但是我用2.5.2也没什么问题
