安装redis3.0.7
下面的操作实例只记录在9cb25bcd52d1：172.17.0.5 上面的操作， 一定要在每个节点都进行操作，对应的端口目录，修改对面的端口
[root@localhost redissoft]# docker-enter 9cb25bcd52d1
Last login: Tue Mar 15 08:13:51 UTC 2016
[root@9cb25bcd52d1 ~]# cd /root/redissoft/
[root@9cb25bcd52d1 redissoft]# ls

[root@9cb25bcd52d1 redissoft]#
[root@9cb25bcd52d1 local]# cp redis-3.0.7.tar.gz /usr/local/
[root@9cb25bcd52d1 local]# tar -xvf redis-3.0.7.tar.gz
[root@9cb25bcd52d1 local]# mv redis-3.0.7 redis3.0
[root@9cb25bcd52d1 local]# cd redis3.0
[root@9cb25bcd52d1 local]# make && make install
创建节点配置文件
保证3个节点都有对应的端口目录
[root@9cb25bcd52d1 redis3.0]# mkdir -p /usr/local/cluster
[root@9cb25bcd52d1 redis3.0]# mkdir -p /usr/local/cluster/7005
[root@9cb25bcd52d1 redis3.0]# mkdir -p /usr/local/cluster/7006
[root@9cb25bcd52d1 redis3.0]# cp -rf /usr/local/redis3.0/* /usr/local/cluster/7005/
[root@9cb25bcd52d1 redis3.0]# cp -rf /usr/local/redis3.0/* /usr/local/cluster/7006/
[root@9cb25bcd52d1 redis3.0]#
修个节点配置文件
保证3个节点都要在相应的配置文件内配置相应的端口号，只修改列出的项目；
[root@9cb25bcd52d1 redis3.0]# vi /usr/local/cluster/7005/redis.conf
port 7005
daemonize yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
[root@9cb25bcd52d1 redis3.0]# vi /usr/local/cluster/7006/redis.conf
port 7006
daemonize yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
启动服务
保证3个节点都要起来
[root@9cb25bcd52d1 cluster]# cd /usr/local/cluster/7005/src/
[root@9cb25bcd52d1 src]# ./redis-server ../redis.conf
[root@9cb25bcd52d1 src]# cd /usr/local/cluster/7006/src/

创建结束后我们会发现有：
3个主节点：172.17.0.2:7001 172.17.0.2:7003 172.17.0.2:7005 这正是我们想要的结果
集群测试
发现3个set语句都把数据存在不同节点的slot里面了，读取的时候也从相应节点进行读取
[root@e2189fc1d4d9 ~]# redis-cli -c -p 7001

在宿主机192.168.100.67上安装redis3.0.7之后同样可以连接redis集群环境，因为容器与主机有端口映射关系
[root@localhost ~]# cp redis-3.0.7.tar.gz /usr/local/
[root@localhost ~]# cd /usr/local/
[root@localhost ~]# tar -xvf redis-3.0.7.tar.gz
[root@localhost ~]# mv redis-3.0.7 redis3.0
[root@localhost ~]# cd redis3.0/
[root@localhost ~]# make
[root@localhost ~]# make install
[root@localhost ~]# netstat -an |grep :::700
