环境：centos 7

一、编译及安装redis源码

源码地址：redis版本发布列表

cd redis-3.2.8
sudo make && make install

 编译安装成功之后，将源码中的 redis-trib.rb 文件拷贝到 /usr/local/bin/ 目录下

sudo cp ./redis-trib.rb /usr/local/bin/

二、创建节点

 创建Redis-Cluster 文件夹，并创建7000-7005共6个文件夹

复制源码中的redis.conf文件并修改以下内容后分别放入7000-7005文件夹

bind 192.168.1.105
port 7000
cluster-enabled yes
cluster-config-file /home/jabben/Redis-Cluster/7000/nodes-7000.conf
pidfile /home/jabben/Redis-Cluster/7000/redis_7000.pid
cluster-node-timeout 5000
daemonize yes

分别启动6个Redis节点：

redis-server 7000/redis.conf
redis-server 7001/redis.conf
redis-server 7002/redis.conf
redis-server 7003/redis.conf
redis-server 7004/redis.conf
redis-server 7005/redis.conf

查看redis进程是否已经启动：

ps -ef | grep redis

三、创建集群

 复制redis-trib.rb文件到bin目录下

cd /home/jabben/Redis-Cluster/Source/redis-3.2.8/src
sudo cp redis-trib.rb /usr/local/bin/

安装ruby环境

yum install ruby

安装rubygems组件

yum install rubygems

安装gem-redis

gem install redis

创建集群

redis-trib.rb create --replicas 1 192.168.1.105:7000 192.168.1.105:7001 192.168.1.105:7002 192.168.1.105:7003 192.168.1.105:7004 192.168.1.105:7005

[OK] All nodes agree about slots configuration.
>>> Check for open slots...
>>> Check slots coverage...
[OK] All 16384 slots covered.

至此集群搭建完毕
