一、redis集群说明
1、redis-cluster架构图，如下：
（1）图中所有节点都是主节点
（2）所有的redis节点彼此互联(PING-PONG机制),内部使用二进制协议优化传输速度和带宽。
（3）节点的fail是通过集群中超过半数的节点检测失效时才生效，所有一般节点数要设置为奇数。
（4）客户端与redis节点直连,不需要中间proxy层.客户端不需要连接集群所有节点,连接集群中任何一个可用节点即可。
（5）redis-cluster把所有的物理节点映射到[0-16383]个slot上,cluster 负责维护。
2、集群怎样存储数据
Redis 集群中内置了 16384 个哈希槽，当需要在 Redis 集群中放置一个 key-value 时，redis 先对 key 使用 crc16 算法算出一个结果，然后把结果对16384求余数，这样每个 key 都会对应一个编号在 0-16383 之间的哈希槽，redis 会根据节点数量大致均等的将哈希槽映射到不同的节点。如图：
key经过算法得到的结果对16384取余得到30，将该key-value放置在server1上，server1对应的槽的编号是0-5000
...
3、集群的容错机制：投票
（1）判断一个节点挂掉：
集群中所有master节点参与投票，如果超过半数的master节点与某一个节点通信超过cluster-node-timeout，认为该master节点挂掉
（2）判断整个集群挂掉，即：cluster_state:fail，满足以下其中一个即可。
a、集群中任意master挂掉，并且没有slave节点。
b、集群中超过半数master挂掉，无论是否有slave，整个集群进入fail状态。
二、搭建集群环境
说明：（1）redis集群管理工具redis-trib.rb依赖ruby环境，首先需要安装ruby环境；
（2）在同一台电脑上模拟6个节点：7001、7002、7003、7004、7005、7006，其中7004是7001的从机 ... ... 依次类推。
1、安装ruby
yum install ruby
yum install rubygems
2、安装ruby和redis的接口程序：redis-3.0.0.gem，首先将该文件上传到服务器 /usr/local 目录下
gem install /usr/local/redis-3.0.0.gem
说明：执行完上面的命令 ，将redis-trib.rb安装到了redis的源文件中（redis-3.0.0/src），参考第几节，查看如下：
3、新建redis-cluster目录，并将集群管理工具redis-trib.rb复制到该目录
mkdir redis-cluster
cp /usr/local/redis-3.0.0/src/redis-trib.rb /usr/local/redis-cluster
4、将redis的bin复制6份到redis-cluster中，分别命名为7001、7002... ... 7006
cp -r /usr/local/redis/bin /usr/local/redis-cluster/7001 cp -r /usr/local/redis/bin /usr/local/redis-cluster/7002 cp -r /usr/local/redis/bin /usr/local/redis-cluster/7003 cp -r /usr/local/redis/bin /usr/local/redis-cluster/7004 cp -r /usr/local/redis/bin /usr/local/redis-cluster/7005 cp -r /usr/local/redis/bin /usr/local/redis-cluster/7006
5、分别修改7001至7006下的redis.conf文件，端口分别设置为7001、7002... ...7006，cluster-enabled设置为：yes
6、删除掉7001至7006中的持久化文件dump.rdb、appendonly.aof
rm -f /usr/local/redis-cluster/7001/dump.rdb appendonly.aof rm -f /usr/local/redis-cluster/7002/dump.rdb appendonly.aof rm -f /usr/local/redis-cluster/7003/dump.rdb appendonly.aof rm -f /usr/local/redis-cluster/7004/dump.rdb appendonly.aof rm -f /usr/local/redis-cluster/7005/dump.rdb appendonly.aof rm -f /usr/local/redis-cluster/7006/dump.rdb appendonly.aof
7、写集群的启动脚本redis-cluster-start.sh，即启动所有节点
cd 7001 ./redis-server ./redis.conf cd .. cd 7002 ./redis-server ./redis.conf cd .. cd 7003 ./redis-server ./redis.conf cd .. cd 7004 ./redis-server ./redis.conf cd .. cd 7005 ./redis-server ./redis.conf cd .. cd 7006 ./redis-server ./redis.conf cd ..
8、给redis-cluster-start.sh赋执行权限
chmod u+x redis-cluster-start.sh
9、启动所有节点
./redis-cluster-start.sh
10、查看是否启动
ps -ef | grep redis
结果如下，全部启动：
三、创建集群
执行以下命令创建集群：
./redis-trib.rb create --replicas 1 192.168.7.151:7001 192.168.7.151:7002 192.168.7.151:7003 192.168.7.151:7004 192.168.7.151:7005 192.168.7.151:7006
运行结果如下：

说明：a、replicas 1是指每个master有一个副本，7001的副本是7004，7002的副本是7005，依次类推... ...
b、创建过程中有提示：Can I set the above configuration? (type 'yes' to accept): 输入yes，如图：
四、集群的管理
1、客户端连接集群
连接上集群中任意一个节点即可，可以是主节点也可以是从节点，如下：
[root@localhost redis-cluster]# ./7001/redis-cli -h 192.168.7.151 -p 7001 -c
连接上集群就可以执行redis命令，set、get等，集群会根据key经过计算存储到不同的节点。
2、查看集群的基本信息和节点信息
192.168.7.151:7001> cluster info
192.168.7.151:7001> cluster nodes
结果如下：
3、集群的关闭、重启与重新搭建
集群的关闭即停掉每一个节点，可以直接杀进程或者用redis-cli shutdown命令。
集群的重启即先停止掉每一个节点，然后依次启动每一个节点即可。
集群的重新搭建需要删除掉每一个节点的持久化文件以及nodes.conf文件，然后重新启动节点，执行redis-trib.rb create命令。
注意：一个主节点宕掉，其从节点会顶上来变为主节点，宕掉的节点重新启动后变成从节点。重新启动集群后，主节点和从节点往往与创建时不一致。
4、添加主节点
（1）在/usr/local/redis-cluster目录下新创建一个节点 7007
cd /usr/local/redis-cluster
cp -r 7001/ 7007
（2）删除掉7007节点的持久化文件和node.conf（这一步一定执行，否则添加失败）
rm -f dump.rdb appendonly.aof nodes.conf
（3）修改7007节点的端口为7007，启动该节点
（4）用redis-trib.rb的add-node命令添加节点，（192.168.7.151:7001可是集群中的任意一个节点）
cd /usr/local/redis-cluster
./redis-trib.rb add-node 192.168.7.151:7007 192.168.7.151:7001
（5）用redis-trib.rb的reshard命令给7007节点分配hash槽，只有分了槽才能存储数据。（192.168.7.151:7001可是集群中的任意一个节点）
cd /usr/local/redis-cluster
./redis-trib.rb reshard 192.168.7.151:7001
填写需要槽的数量：500
填写接收槽的节点ID：cbbce4b5255d81cbbfdb56203091580333df7853（cluster nodes命令查看，7007的ID）
填写源节点ID：表示这些槽要从哪些个节点中拿，这里习惯输入all，表示从所有节点拿，输入done表示取消分配。
填写是否执行分配计划：yes。等待运行结束，添加成功。
注意：在给新节点分配槽时有4处需要输入。
5、添加从节点
（1）在/usr/local/redis-cluster目录下新创建一个节点 7008
cd /usr/local/redis-cluster
cp -r 7001/ 7008
（2）删除掉7008节点的持久化文件和node.conf（这一步一定执行，否则添加失败）
rm -f dump.rdb appendonly.aof nodes.conf
（3）修改7008节点的端口为7008，启动该节点
（4）用redis-trib.rb的add-node命令添加节点，（192.168.7.151:7001可是集群中的任意一个节点）
cd /usr/local/redis-cluster
./redis-trib.rb add-node --slave --master-id cbbce4b5255d81cbbfdb56203091580333df7853 192.168.7.151:7008 192.168.7.151:7001
cbbce4b5255d81cbbfdb56203091580333df7853是主节点ID，执行完该命令添加从节点成功，截图如下：
6、删除节点
[root@localhost redis-cluster]# ./redis-trib.rb del-node 192.168.7.151:7008 2763319a9dd00773c928c9f3c5ebfd2057dbae15
2763319a9dd00773c928c9f3c5ebfd2057dbae15是删除节点7008的id，删除成功截图如下：
查看节点信息，发现7008节点已删除：
注意：如果节点中有数据，不能删除节点，报错：[ERR] Node 192.168.7.151:7007 is not empty! Reshard data away and try again.
