问题：Hint: It's a good idea to run 'make test' ;)

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

/usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- redis (LoadError)

 创建集群失败

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
