準備一台機器，系統版本為centos7。（注意本文描述的是redis-cluster，不是主從複製）

# wget
2、解壓

# tar xvf redis-3.2.8.tar.gz -c /usr/local/


# cd /usr/local/


# ln -sv redis-3.2.8/ redis
3、編譯

# yum groupinstall -y "development tools"


# cd redis


# make
4、為多例項redis配置啟動環境

# mkdir -pv /home/redis-cluster/


# cp src/ /home/redis-cluster/9000/


# cp src/ /home/redis-cluster/9001/


# cp src/ /home/redis-cluster/9002/


# cp redis.conf sentinel.conf /home/redis-cluster/9000/


# cp redis.conf sentinel.conf /home/redis-cluster/9001/


# cp redis.conf sentinel.conf /home/redis-cluster/9002/
5、修改配置檔案

# vim /home/redis-cluster/9000/redis.conf


bind 192.168.135.170


port 9000


daemonize yes


cluster-enabled yes


cluster-config-file nodes.conf


cluster-node-timeout 5000


# \cp /home/redis-cluster/9000/redis.conf /home/redis-cluster/9001/redis.conf


# \cp /home/redis-cluster/9000/redis.conf /home/redis-cluster/9002/redis.conf


# vim /home/redis-cluster/9001/redis.conf


port 9001


# vim /home/redis-cluster/9002/redis.conf


port 9002
6、啟動三個redis例項

# cd /home/redis-cluster/9000/


# ./redis-server redis.conf


# cd ../9001/


# ./redis-server redis.conf


# cd ../9002/


# ./redis-server redis.conf


# ps -ef | grep redis


root 15583 1 0 00:32 ? 00:00:00 ./redis-server 192.168.135.170:9000 [cluster]


root 15592 1 0 00:33 ? 00:00:00 ./redis-server 192.168.135.170:9001 [cluster]


root 15597 1 0 00:33 ? 00:00:00 ./redis-server 192.168.135.170:9002 [cluster]
7、安裝ruby環境

# yum install -y ruby


# gem install redis
8、啟動redis集群

9、檢視集群狀態

# /usr/local/redis/src/redis-cli -c -h 192.168.135.170 -p 9000


9000> cluster info


cluster_state:ok


cluster_slots_assigned:16384


cluster_slots_ok:16384


cluster_slots_pfail:0


cluster_slots_fail:0


cluster_known_nodes:3


cluster_size:3


cluster_current_epoch:3


cluster_my_epoch:1


cluster_stats_messages_sent:364


cluster_stats_messages_received:364
