本文档基于如下原始文档（CentOS）创建：
修改了一些路径的错误，补全了一些命令执行结果信息，确认在Mac下创建集群成功
同时参考
（要让集群正常工作至少需要3个主节点，在这里我们要创建6个redis节点，其中三个为主节点，三个为从节点，对应的redis节点的ip和端口对应关系如下）
- 127.0.0.1:7000
- 127.0.0.1:7001
- 127.0.0.1:7002
- 127.0.0.1:7003
- 127.0.0.1:7004
- 127.0.0.1:7005
1：官网下载3.0.1 Stable （http://redis.io/）
2：上传服务器，解压，编译
#将下载的文件放到 /usr/local/ tar -zxvf redis-3.0.1.tar.gz #生成 redis-3.0.1文件夹 cd /usr/local/redis-3.0.1 make make install #执行一下make test查看 make的结果全部都是OK #最终结果显示如下 o/ All tests passed without errors!
3：创建集群需要的目录
mkdir -p /usr/local/cluster cd /usr/local/cluster mkdir 7000 mkdir 7001 mkdir 7002 mkdir 7003 mkdir 7004 mkdir 7005
4：修改配置文件redis.conf
cp /usr/local/redis-3.0.1/redis.conf /usr/local/cluster vi redis.conf ##修改配置文件中的下面选项 port 7000 daemonize yes cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 appendonly yes ##修改完redis.conf配置文件中的这些配置项之后把这个配置文件分别拷贝到7000/7001/7002/7003/7004/7005目录下面 cp /usr/local/cluster/redis.conf /usr/local/cluster/7000 cp /usr/local/cluster/redis.conf /usr/local/cluster/7001 cp /usr/local/cluster/redis.conf /usr/local/cluster/7002 cp /usr/local/cluster/redis.conf /usr/local/cluster/7003 cp /usr/local/cluster/redis.conf /usr/local/cluster/7004 cp /usr/local/cluster/redis.conf /usr/local/cluster/7005 ##注意：拷贝完成之后要修改7001/7002/7003/7004/7005目录下面redis.conf文件中的port参数，分别改为对应的文件夹的名称
5：分别启动这6个redis实例(实践证明，必须要cd到700X文件夹下执行redis-server命令)
cd /usr/local/cluster/7000 redis-server redis.conf cd /usr/local/cluster/7001 redis-server redis.conf cd /usr/local/cluster/7002 redis-server redis.conf cd /usr/local/cluster/7003 redis-server redis.conf cd /usr/local/cluster/7004 redis-server redis.conf cd /usr/local/cluster/7005 redis-server redis.conf ##启动之后使用命令查看redis的启动情况ps -ef|grep redis 如下显示则说明启动成功 X0544:7005 wei.li$ ps -ef | grep redis 909302175 5547 1 0 11:31上午 ?? 0:01.07 redis-server *:7000 [cluster] 909302175 5736 1 0 11:44上午 ?? 0:00.29 redis-server *:7001 [cluster] 909302175 5761 1 0 11:48上午 ?? 0:00.05 redis-server *:7002 [cluster] 909302175 5773 1 0 11:49上午 ?? 0:00.03 redis-server *:7003 [cluster] 909302175 5780 1 0 11:49上午 ?? 0:00.02 redis-server *:7004 [cluster] 909302175 5787 1 0 11:49上午 ?? 0:00.01 redis-server *:7005 [cluster] 909302175 5790 952 0 11:49上午 ttys000 0:00.00 grep redis
6：执行redis的创建集群命令创建集群
cd /usr/local/redis-3.0.1/src ./redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005
请注意：
本机已经安装rvm和rubygems，只需要执行
X0544:cluster wei.li$ gem install redis -V
即可安装完毕redis-rb
正常执行结果如下
X0544:src wei.li$ ./redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 >>> Creating cluster Connecting to node 127.0.0.1:7000: OK Connecting to node 127.0.0.1:7001: OK Connecting to node 127.0.0.1:7002: OK Connecting to node 127.0.0.1:7003: OK Connecting to node 127.0.0.1:7004: OK Connecting to node 127.0.0.1:7005: OK >>> Performing hash slots allocation on 6 nodes...

至此redis集群即搭建成功！
7：使用redis-cli命令进入集群环境
X0544:src wei.li$ redis-cli -c -p 7000 127.0.0.1:7000>
8: 测试集群状态
