启动各节点：
redis-server /usr/local/redis/redis-cluster/nodes-7001/redis.conf
redis-server /usr/local/redis/redis-cluster/nodes-7002/redis.conf
redis-server /usr/local/redis/redis-cluster/nodes-7003/redis.conf
redis-server /usr/local/redis/redis-cluster/nodes-7004/redis.conf
redis-server /usr/local/redis/redis-cluster/nodes-7005/redis.conf
redis-server /usr/local/redis/redis-cluster/nodes-7006/redis.conf

kill -9 `ps -ef | grep redis | grep -v grep | awk ‘{print $2}‘`

安装ruby:
cd /usr/local/redis/
tar -zxvf ruby-2.3.2.tar.gz
cd ruby-2.3.2
./configure
make && make install
gem install redis

redis-trib.rb create --replicas 1 192.168.8.14:7001 192.168.8.14:7002 192.168.8.14:7003 192.168.8.15:7004 192.168.8.15:7005 192.168.8.15:7006
