安装codis
创建编译目录
mkdir -pv /usr/local/gopkg/src/github.com/CodisLabs
编译
mv codis.xxx coids &&cd codis&&make
之后生成一个bin目录 将目录copy到codis启动目录下我的目录是 /export/codis/

codis可用性测试：
一下内容为其他测试集群测试
目前redis-port不支持从twemproxy 读取，因此只能将redis作为数据源进行数据同步。
原理：
简单的来说就是静态解析rdb到redis。
官方介绍有四个功能：
DECODE dumped payload to human readable format (hex-encoding)
RESTORE rdb file to target redis
DUMP rdb file from master redis
SYNC data from master to slave
线下导入测试
先查看codis数据量 
进行导入：

再次查看codis key
从图上看key，已经进行导入。
注（源端可以边写边导入，尽可能的减少key损失）
主从切换&&数据导入测试
从目前来看我们就一个组一个实例单点，
下面我们添加节点，并进行数据迁移以及主机故障测试
可以看到 在复制过程中如果数据没有复制完成会丢失。
下面启动20002的redis进程，并将20002提升为主
查看在同步过程中将某一台下线，其中同步的key将永久丢失。
