redis-cluster搭建

一、redis.conf

1、port 7001
2、daemonize yes
3、bind 52.27.105.14
4、dir "/opt/app/redis-cluster/7001"(rdb或aof文件)
5、cluster-enabled yes（启动集群模式）
6、cluster-config-file nodes-7001.conf（存放所有的节点信息，会在dir目录下自动生成。需要把该文件删除，才能创建新的集群）
7、cluster-node-timeout 5000
8、logfile "/opt/app/redis-cluster/7001/log/redis.log"

二、ruby等环境

yum install ruby

yum install rubygems

gem install redis （安装redis和ruby的接口）

三、启动

./redis-server /opt/app/redis-cluster/7001/redis.conf
./redis-server /opt/app/redis-cluster/7002/redis.conf
./redis-server /opt/app/redis-cluster/7003/redis.conf
./redis-server /opt/app/redis-cluster/7004/redis.conf
./redis-server /opt/app/redis-cluster/7005/redis.conf
./redis-server /opt/app/redis-cluster/7006/redis.conf

./redis-trib.rb create --replicas 1 192.168.220.133:7001 192.168.220.133:7001 192.168.220.133:7002 192.168.220.133:7003 192.168.220.133:7004 192.168.220.133:7005 192.168.220.133:7006

1、复制与故障转移：kill 7001后7004会升为master且7001的slot指派给7004；启动7001后，7001会成为7004的slave

 

四、检查

./redis-cli -c -h 52.27.105.14 -p 7001

1、info

2、cluster info

3、cluster nodes
