环境：

主机1 192.168.2.204

主机2 192.168.2.201

步骤：

安装redis

参考初试redis主从同步

主机1 启动3台redis

mkdir /install/redisconf /install/redisconf/7000 /install/redisconf/7001 /install/redisconf/7002

cp /install/redis/redis.conf /install/redisconf/7000

cp /install/redis/redis.conf /install/redisconf/7001

cp /install/redis/redis.conf /install/redisconf/7002

修改三个配置文件

port 7000(7001/7002)

bind 192.168.2.204

daemonize yes

pidfile /var/run/redis_7000(7001/7002).pid

cluster-enabled yes

cluster-config-file nodes_7000(7001/7002).conf

appendonly yes

redis-server /install/redisconf/7000/redis.conf

redis-server /install/redisconf/7001/redis.conf

redis-server /install/redisconf/7002/redis.conf

主机2同上开启三个redis分别为7003、7004、7005

创建集群

cp /download/redis-3.2.1/src/redis-trub.rb /usr/local/bin

主从对应

$ruby redis-trib.rb create --replicas 1 192.168.2.204:7000 192.168.2.204:7001 192.168.2.204:7002 192.168.2.201:7003 192.168.2.201:7004 192.168.2.201:7005

此处报错

因为ruby没有安装另外此处有坑，ruby需安装1.8以上版本，否则需要安装gem

cd /soft

wget https://cache.ruby-china.org/pub/ruby/ruby-2.4.1.tar.gz

tar zxvf ruby-2.4.1

cd ruby-2.4.1

./configure --with-openssl-dir=/usr/local/ssl

make && make install

cp /usr/local/bin/ruby /usr/bin

重新执行

$ruby redis-trib.rb create --replicas 1 192.168.2.204:7000 192.168.2.204:7001 192.168.2.204:7002 192.168.2.201:7003 192.168.2.201:7004 192.168.2.201:7005

再次报错

Waiting for the cluster to join......................................................................................................................
...........................................................

检查防火墙接口正常

原来 redis 集群创建的时候会默认使用集群端口来通信，端口号为对应redis通信接口+10000 于是开启防火墙

再次执行

$ruby redis-trib.rb create --replicas 1 192.168.2.204:7000 192.168.2.204:7001 192.168.2.204:7002 192.168.2.201:7003 192.168.2.201:7004 192.168.2.201:7005
