测试数据写入
　　我们需要给源集群写入测试数据，然后才能进行数据迁移。数据写入脚本如下：
for i in `seq 1000000`;
do
redis-cli -c -h 127.0.0.1 -p 7000 -a 123456 set k:$i v:$i
done
可以看出，上面的脚本共写入了1000000条数据。Redis集群会根据key的hash进行数据分区，如下：
http://www.51testing.com/attachments/2021/07/15326825_202107021613412kpBA.png

　　此外，为了测试数据过滤功能，还额外写入了10W条其他key，如下：
http://www.51testing.com/attachments/2021/07/15326825_202107021613411T8XJ.png

　　Redis-Shake测试
　　首先，在github上下载最新的redis-shake-v2.0.3.tar.gz并解压。
/mnt/c/Users/wangy ? tar -xvf redis-shake-v2.0.3.tar.gz
./._redis-shake-v2.0.3
./redis-shake-v2.0.3/
./redis-shake-v2.0.3/._.DS_Store
./redis-shake-v2.0.3/.DS_Store
./redis-shake-v2.0.3/ChangeLog
./redis-shake-v2.0.3/redis-shake.linux
./redis-shake-v2.0.3/redis-shake.conf
./redis-shake-v2.0.3/redis-shake.windows
./redis-shake-v2.0.3/._stop.sh
./redis-shake-v2.0.3/stop.sh
./redis-shake-v2.0.3/._start.sh
./redis-shake-v2.0.3/start.sh
./redis-shake-v2.0.3/redis-shake.darwin打开其中的redis-shake.conf进行修改，下面仅列出与本次测试相关的配置项。
# 源端redis的类型，支持standalone，sentinel，cluster和proxy四种模式，注意：目前proxy只用于rump模式。
source.type = cluster
# 源redis地址。
source.address = 172.25.253.0:7002;172.25.253.0:7000;172.25.253.0:7001;172.25.253.0:7003;172.25.253.0:7040;172.25.253.0:7005
# password of db/proxy. even if type is sentinel.
source.password_raw = 123456
# auth type, don't modify it
source.auth_type = auth
# 目的redis的类型，支持standalone，sentinel，cluster和proxy四种模式。
target.type = cluster
target.address = 172.25.253.0:8000;172.25.253.0:8001;172.25.253.0:8002;172.25.253.0:8003;172.25.253.0:8004
# password of db/proxy. even if type is sentinel.
target.password_raw = 123456
# auth type, don't modify it
target.auth_type = auth
# 支持按前缀过滤key，只让指定前缀的key通过，分号分隔。比如指定abc，将会通过abc, abc1, abcxxx
filter.key.whitelist = k:配置好之后，使用下面的命令启动：
/mnt/c/Users/wangy/redis-shake-v2.0.3 ? ./redis-shake.linux -type=sync -conf=redis-shake.conf
2021/03/20 15:55:10 source.auth_type != auth
2021/03/20 15:55:10 target.auth_type != auth
2021/03/20 15:55:10 the target redis type is cluster, only pass db0
2021/03/20 15:55:10 source rdb checksum
2021/03/20 15:55:10 source rdb checksum
2021/03/20 15:55:10 source rdb checksum
2021/03/20 15:55:10

当观察到sync rdb done，表面全量迁移完成，接下来是增量迁移。
　　经测试，利用工具redis-shake，可以快速对Redis集群的数据进行迁移。
