docker volume 掛載文件後，容器內更新文件時，報 Device or resource busy
# Error moving temp DB file temp-1.rdb on the final destination dump.rdb (in server root dir /usr/local/redis/data): Device or resource busy
掛載源地址和目標地址改爲目錄，而不是文件
如：/root/compose/data-volumes/redis/dump.rdb:/usr/local/redis/data/dump.rdb
改爲
/root/compose/data-volumes/redis:/usr/local/redis/data
