Redis 各版本下载地址: http://download.redis.io/releases/
版本说明:一般来说版本号第二位,偶数是稳定版本,奇数是在开发中的版本
本文基于Redis 版本为:3.2.12

和一主多从有变化的配置,其它环节一致

现切换成一主多从结构 ,在一主多从的情况下,搭建三个哨兵

# . 相对于命令运行路径,最好写绝对路径
cluster-config-file ./nodes-6379.conf
其它 master slave 只需要修改端口号即可,然后使用 ./redis-server <configfile>

redis集群有16384个哈希槽,要把所有数据映射到16384槽,需要批量设置槽
# 查询集群状态
192.168.108.128:6381> cluster info
cluster_state:fail
# 显示为 fail 是还没有映射槽,还不能提供服务
