1、获取redis源码包
2、解压进入目录并安装make && make install
3、cd /usr/local/mkdir redis_clustercd redis_clustermkdir 7000 7001 7002 7003 7004 7005 //分别代表三个节点 其对应端口 7000 7001 7002//创建7000节点为例，拷贝到7000目录cp /usr/local/redis-3.2.1/redis.conf ./redis_cluster/7000/ cp /usr/local/redis-3.2.1/redis.conf ./redis_cluster/7001/ cp /usr/local/redis-3.2.1/redis.conf ./redis_cluster/7002/cp /usr/local/redis-3.2.1/redis.conf ./redis_cluster/7003/ cp /usr/local/redis-3.2.1/redis.conf ./redis_cluster/7004/ cp /usr/local/redis-3.2.1/redis.conf ./redis_cluster/7005/
4、修改配置文件daemonize yes //redis后台运行pidfile /var/run/redis_7000.pid //pidfile文件对应7000,7002,7003port 7000 //端口7000,7002,7003cluster-enabled yes //开启集群 把注释#去掉cluster-config-file nodes_7000.conf //集群的配置 配置文件首次启动自动生成 7000,7001,7002cluster-node-timeout 5000 //请求超时 设置5秒够了appendonly yes //aof日志开启 有需要就开启，它会每次写操作都记录一条日志
5、cd /usr/localredis-server redis_cluster/7000/redis.confredis-server redis_cluster/7001/redis.confredis-server redis_cluster/7002/redis.confredis-server redis_cluster/7003/redis.confredis-server redis_cluster/7004/redis.confredis-server redis_cluster/7005/redis.conf
6、安装yum仓库yum install centos-release-scl-rh
7、安装高版本的rubyyum install rh-ruby23 -y
8、scl enable rh-ruby23 bash
9、安装gemgem install redis
10、启动集群/usr/local/redis-3.2.1/src/redis-trib.rb create --replicas 1 192.168.122.204:7000 192.168.122.204:7001 192.168.122.204:7002 192.168.122.204:7003 192.168.122.204:7004192.168.122.204:7005
11、创建完成
12、测试，在7000上set，在7002上get
