RedisInsight添加Redis主機

使用BULK ACTION Restore數據

我是用k8s佈屬RedisInsight，所以才看一下，佈屬到哪個節點，需要把要恢復數據的RBD檔案，傳至那台主機RedisInsight POD裡面

用RedisInsight BULK ACTIONS復原數據的效果

以下是將RBD檔案複製到REDIS目錄，一台一台REDIS服務重啟，慢慢導入RBD數據的效果

看起來效果是一樣，但是使用RedisInsight BULK ACTIONS，有幾個好處：

  1. Redis服務不用重啟，線上恢復數據
  2. Redis slot不會有異常分配狀況，還要使用–cluster fix的狀況發生

測試數據，是否正確，結果->有些數據Key Name被修改了

來查查看數據，是不是跟之前使用重啟Redis服務恢復數據時，得到的一樣

以下是使用重啟Redis服務恢復數據時，查到的key和value

[root@redis01 redis]# redis-cli --user 帳號 --pass 密碼 -c

# 查看key type，此key剛好就在redis01主機上，所以執行直接顯示type

# 查看key type，此key在redis02主機上，會Redirected到此key所在slot主機上，再顯示type

注意：可以看到，有些數據找不到了

可以看到，數據樣式變了，此恢復數據方式會有問題，不可用
