Redis3.2 Cluster

1. download redis 3.2

2. make PREFIX=/usr/local/redis/ install

3. 拷贝配置文件到安装文件 cp /usr/soft/redis-3.0.7/redis.conf /usr/local/redis/bin/

4. 安装完后，只有BIN文件夹，

5. yum install ruby
   yum install rubygems
   redis 3 as ruby version 1.9.3

   download redis3.0.gem

   gem install /usr/local/redis-3.0.0.gem

6. 建立， 7000, 7001, 8000, 8001,9000,9001 六个文件夹

7. 讲单个安装成功的BIN文件夹拷贝到上述文件夹

8. 修改各个文件夹的redis.conf, 修改IP地址，端口号， node

bin ip
cluster-enabled yes
cluster-config-file nodes-7000.conf

9. 后台启动六个实例

./7000/bin/redis-server ./7000/bin/redis.conf &
./7001/bin/redis-server ./7001/bin/redis.conf &

./9001/bin/redis-server ./9001/bin/redis.conf &

9. 拷贝redis-trib.rb

10 ./redis-trib.rb create --replicas 1 192.168.24.2:7000 192.168.24.2:7001 192.168.24.2:8000 192.168.24.2:8001 192.168.24.2:9000 192.168.24.2:9001

11. 登录到集群

./7000/bin/redis-cli -h 192.168.24.2 -p 7000 -c

   -c 表示连接到集群

   测试， ping
   pong

   查看集群信息
   cluster info

12 添加主节点

./redis-trib.rb add-node 192.168.198.130:7007 192.168.198.130:7001
        重新分配槽数量
./redis-trib.rb reshard 192.168.198.130:7001（连接集群中任意一个可用结点都行）

13. 添加从节点

./redis-trib.rb add-node --slave --master-id db786026ed607786d6db1aaab94fd73d1ac3c8f4 192.168.198.130:7008 192.168.198.130:7001
        重新分配槽数量
./redis-trib.rb reshard 192.168.198.130:7001（连接集群中任意一个可用结点都行）
