安裝部署

安裝Python2.7下載redis-rdb-toolsgit clone https://github.com/sripathikrishnan/redis-rdb-tools.git安裝redis-rdb-toolspip2.7 install  python-lzfcd redis-rdb-toolspython2.7 setup.py install

常見用法:

# 以json格式輸出> rdb --command json /var/redis/6379/dump.rdb# 以json格式輸出，模糊尋找> rdb --command justkeyvals --key "user.*" /var/redis/6379/dump.rdbuser003 fname Ron,sname Bumquist,user001 fname Raoul,sname Duke,user002 fname Gonzo,sname Dr,user_list user003,user002,user001# 尋找確定鍵資訊> redis-memory-for-key -s localhost -p 6379 -a mypassword person:1Key             person:1Bytes               111Type                hashEncoding            ziplistNumber of Elements      2Length of Largest Element   8# rdb檔案解析並輸出為csv> rdb -c memory /var/redis/6379/dump.rdb --bytes 128 -f memory.csv> cat memory.csvdatabase,type,key,size_in_bytes,encoding,num_elements,len_largest_element0,list,lizards,241,quicklist,5,190,list,user_list,190,quicklist,3,72,hash,baloon,138,ziplist,3,112,list,armadillo,231,quicklist,5,202,hash,aroma,129,ziplist,3,11#  輸出top10的鍵資訊rdb -c memory  --largest=10  /app/redis/data/7000/dump.rdb

報錯及解決方案：

在redis-cluster模式下使使用者出現如下報錯，將地址改為該鍵對應的地址即可

注意事項：

1、整個rdb檔案的解析會導致CPU佔用嚴重，所以慎用！！！2、最好選擇單鍵查詢的方式，不太消耗資源3、如果需要解析某個rdb檔案，最好使用它的備份檔案，或者將檔案匯出到本地或者測試機進行解析
