一、准备好三台虚拟机
192.168.152.128
192.168.152.129
192.168.152.130
二、安装
先在192.168.152.128安装redis
创建conf目录

[root@localhost redis-5.0.3]# mkdir -p conf/6379
[root@localhost redis-5.0.3]# mkdir -p conf/6380
#redis配置复制一份到配置目录
[root@localhost redis-5.0.3]# cp redis.conf conf/6379
[root@localhost redis-5.0.3]# cp redis.conf conf/6380
修改6380目录下redis.conf配置文件的的端口号为6380

修改conf/6379/redis.conf为 配置

#bind 127.0.0.1  注释掉
protected-mode no（需要不同服务器的节点连通，这个就要设置为 no）
daemonize yes（设置后台运行redis）
cluster-enabled yes
cluster-node-timeout 5000
appendonly yes
port 6379
pidfile /var/run/redis_6379.pid
cluster-config-file nodes-6379.conf
dbfilename dump_6379.rdb
appendfilename "appendonly_6379.aof"
logfile "/var/log/redis/redis_6379.log"

修改conf/6380/redis.conf为 配置

#bind 127.0.0.1  注释掉
protected-mode no（需要不同服务器的节点连通，这个就要设置为 no）
daemonize yes（设置后台运行redis）
cluster-enabled yes
cluster-node-timeout 5000
appendonly yes
port 6380
pidfile /var/run/redis_6380.pid
cluster-config-file nodes-6380.conf
dbfilename dump_6380.rdb
appendfilename "appendonly_6380.aof"
logfile "/var/log/redis/redis_6380.log"

将安装好的redis复制一份到另外两台机器

scp -r redis-5.0.3 root@192.168.152.129:/usr/local
scp -r redis-5.0.3 root@192.168.152.130:/usr/local

三、 启动redis
在三台机器上执行下面两条启动命令

root@localhost redis-5.0.3]# /usr/local/redis-5.0.3/src/redis-server /usr/local/redis-5.0.3/conf/6379/redis.conf 
root@localhost redis-5.0.3]# /usr/local/redis-5.0.3/src/redis-server /usr/local/redis-5.0.3/conf/6380/redis.conf 

四、 创建集群

[root@localhost src]# ./redis-cli --cluster create 192.168.152.128:6379 192.168.152.129:6379 192.168.152.130:6379 192.168.152.128:6380 192.168.152.129:6380 192.168.152.130:6380 --cluster-replicas 1
