虽然这里用的是4.0.8的包，但是你可以下个5以上的包，因为redis5以前的版本集群是依靠ruby脚本redis-trib.rb实现，需要安装ruby环境，而redis5以上可以使用redis-cli创建整个redis集群
[root@node1 ~]# tar xf redis-4.0.8.tar.gz
[root@node1 ~]# yum -y install gcc make
[root@node1 ~]# cd redis-4.0.8/
[root@node1 redis-4.0.8]# make
#官方默认redis放在前台，占用终端。这里修改配置，放在后台
[root@node1 redis-4.0.8]# vim +136 redis.conf
daemonize yes
[root@node1 redis-4.0.8]# src/redis-server redis.conf
[root@node1 redis-4.0.8]# ss -antup | grep redis
?[root@node1 redis-4.0.8]# src/redis-cli
127.0.0.1:6379> set hello world
OK
127.0.0.1:6379> get hello
"world"
127.0.0.1:6379>exit
[root@node1 redis-4.0.8]# src/redis-cli shutdown
[root@node1 redis-4.0.8]# ss -antup | grep redis
[root@node1 ~]# mv redis-4.0.8 /opt/
[root@node1 ~]# cd /opt/
查看6381-6386端口，确保端口未被使用
[root@node1 redis-4.0.8]# ss -antup | grep 8381
[root@node1 opt]# mkdir -p cluster/{6381,6382,6383,6384,6385,6386}

[root@node1 opt]# for i in {6382..6386}; do cp cluster/6381/redis.conf ?cluster/$i/; done

Can I set the above configuration? (type 'yes' to accept): yes
[OK] All nodes agree about slots configuration.
>>> Check for open slots...
>>> Check slots coverage...
[OK] All 16384 slots covered.
redis5以上可以使用redis-cli创建整个redis集群()，这里有密码 -a ?123456
[root@node1 opt]# ?redis-4.0.8/src/redis-cli -a 123456?--cluster create --cluster-replicas 1?127.0.0.1:6381 127.0.0.1:6382 127.0.0.1:6383 127.0.0.1:6384 127.0.0.1:6385 127.0.0.1:6386
[root@node1 opt]# redis-4.0.8/redis-cli -h 127.0.0.1 -p 6381
?[root@node1 ~]# ps -aux | grep redis | awk '/Ssl/{print $2}' |xargs kill -9
