實現目的與流程
- 從來源5台master使用bgsave指令，產生各master的數據檔案dump.rdb，共會產生5個dump.rdb檔
- 將來源dump.rdb檔案傳送至目的5台master的redis工作目錄下，覆蓋原dump.rdb檔
- 一台一台重啟redis服務
- 重啟一台redis服務，就檢查一次數據恢復狀況(–cluster check)，並修復(–cluster fix)
- 確定檢查正常，再執行下一台redis服務重啟
- 直到5台都執行完畢，確認數據全部還原至目的集群
注意：以上流程，一定要一台一台來執行，不能一次全部重啟redis服務

測試key與value是否正常
藉由type key方式，確認是否有查到key的type，
並確認是否針對key所在slot的位置，有Redirected過去key所在的主機，
並查看key是否有取到正確的值。
