创建集群
由于 Redis 集群需要使用 ruby 命令，所以我们需要安装 ruby 和相关接口。
yum install ruby
yum install rubygems
gem install redis
redis操作指令
注意事项：
Redis报错：WRONGTYPE Operation against a key holding the wrong kind of value 解决处理
hkeys ifs....
./redis-cli -h 192.25.106.44 -p 7111 -a 'hsstr.COM'
$ redis-cli -h host -p port -a password
redis 集群链接：
redis-cli -c -h host -p port -a password
redis重启
netstat -tnlp|grep 6389
pwdx 29315 查找pid进程所在的程序路径
kill 29315
python 连接异常
redis.exceptions.ResponseError: CLUSTERDOWN The cluster is down
如果是用apt-get或者yum install安装的redis，可以直接通过下面的命令停止/启动/重启redis
/etc/init.d/redis-server stop
/etc/init.d/redis-server start
/etc/init.d/redis-server restart
如果是通过源码安装的redis，则可以通过redis的客户端程序redis-cli的shutdown命令来重启redis
redis-cli -h 127.0.0.1 -p 6379 shutdown
如果上述方式都没有成功停止redis，则可以使用终极武器 kill -9

解答：设置了密码，删除密码即可
创建集群一直处在创建中。。。

创建键值的时候报错
解答：全局连接redis
仔细观察能够注意到，redis-cli根据指示，不断在7000和7002结点之前重定向跳转。如果启动时不加-c选项的话，就能看到以错误形式显示出的MOVED重定向消息。 [root@8gVm redis-3.0.4]# src/redis-cli -h 192.168.5.130 -p 7001 192.168.5.130:7001> get foo (error) MOVED 7252 192.168.5.129:7004
