Redis5.0集群安装
一、准备好三台虚拟机：
node1 （192.168.2.4）、
node2（ 192.168.2.5）、
node3（ 192.168.2.6）
二、编译安装（node1）
yum -y install gcc gcc-c++ libstdc++-devel tcl -y
make MALLOC=lib
make install PREFIX=/usr/local/redis （安装目录）
三、修改配置文件，拷贝到其他机器
node1服务器:
mkdir -p /usr/local/redis/redis_cluster/7000
mkdir -p /usr/local/redis/redis_cluster/7001
cp redis.conf /usr/local/redis/redis_cluster/7000
修改端口为7000
cp redis.conf /usr/local/redis/redis_cluster/7001
修改端口为7001
scp /usr/local/redis/redis_cluster/7000/redis.conf node2:/usr/local/redis/redis_cluster/7000
scp /usr/local/redis/redis_cluster/7001/redis.conf node2:/usr/local/redis/redis_cluster/7001
scp /usr/local/redis/redis_cluster/7000/redis.conf node3:/usr/local/redis/redis_cluster/7000
scp /usr/local/redis/redis_cluster/7001/redis.conf node3:/usr/local/redis/redis_cluster/7001
四、启动命令，在node1和node2、node3执行
/usr/local/redis/bin/redis-server /usr/local/redis/redis_cluster/7000/redis.conf
/usr/local/redis/bin/redis-server /usr/local/redis/redis_cluster/7001/redis.conf
五、创建集群命令
./redis-cli --cluster create 192.168.2.4:7000 192.168.2.5:7000 192.168.2.6:7000 192.168.2.4:7001 192.168.2.5:7001 192.168.2.6:7001 --cluster-replicas 1
成功如下图：
