    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：
    1. for i in `seq 1000000`;
    2. do
    3. redis-cli -c -h 127.0.0.1 -p 7000 -a 123456 set k:$i v:$i
    4. done
    复制代码

    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：


    　　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：


    　　Redis-Shake测试
    　　首先，在github上下载最新的redis-shake-v2.0.3.tar.gz并解压。
    1. /mnt/c/Users/wangy ? tar -xvf redis-shake-v2.0.3.tar.gz
    2. ./._redis-shake-v2.0.3
    3. ./redis-shake-v2.0.3/
    4. ./redis-shake-v2.0.3/._.DS_Store
    5. ./redis-shake-v2.0.3/.DS_Store
    6. ./redis-shake-v2.0.3/ChangeLog
    7. ./redis-shake-v2.0.3/redis-shake.linux
    8. ./redis-shake-v2.0.3/redis-shake.conf
    9. ./redis-shake-v2.0.3/redis-shake.windows
    10. ./redis-shake-v2.0.3/._stop.sh
    11. ./redis-shake-v2.0.3/stop.sh
    12. ./redis-shake-v2.0.3/._start.sh
    13. ./redis-shake-v2.0.3/start.sh
    14. ./redis-shake-v2.0.3/redis-shake.darwin
    复制代码
    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。
    1. # 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。
    2. source.type = cluster
    3. # 源redis地址。
    4. 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
    5. # password of db/proxy. even if type is sentinel.
    6. source.password_raw = 123456
    7. # auth type, don't modify it
    8. source.auth_type = auth
    9. # 目的redis的类型，支持standalone，sentinel，cluster和proxy四种模式。
    10. target.type = cluster
    11. 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
    12. # password of db/proxy. even if type is sentinel.
    13. target.password_raw = 123456
    14. # auth type, don't modify it
    15. target.auth_type = auth
    16. # 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
    17. filter.key.whitelist = k:
    复制代码
    配置好之后，使用下面的命令启动：
    1. /mnt/c/Users/wangy/redis-shake-v2.0.3 ? ./redis-shake.linux -type=sync -conf=redis-shake.conf
    2. 2021/03/20 15:55:10 [WARN] source.auth_type[auth] != auth
