创建6个redis容器集群

以redis7000为例：

非集群模式

# docker run --name redis8000 -p 8000:6379 -d redis redis-server --requirepass "123456" --appendonly yes --protected-mode no

集群模式

# docker run --name redis7000 -p 7000:6379 -d redis redis-server --requirepass "123456" --appendonly yes --protected-mode no --cluster-enabled yes

说明：

redis的密码为123456

Redis持久化功能已启动

保护模式已经关闭

集群模式已开启
