MongoDB備份-mongodump和恢復-mongorestore
阿新 • • 發佈:2019-02-09
備份
mongodump -h dbhost -d dbname -o dbdir
上述語法中:
-h MongDB所在伺服器,可以附帶指定埠號‘:port’
-d 需要備份的資料庫例項
-o 備份資料存放的位置
如果以上引數都不指定,預設備份127.0.0.1埠號27017的所有資料庫到當前的dump目錄

恢復
mongorestore -h hostname:port -d dbname <path>
一些重要的引數
-h[:port] 指定MongoDB所在的伺服器地址,預設為localhost
-d 需要恢復的資料庫
--drop 恢復的時候先刪除當前資料庫,然後恢復備份,慎重操作
<path> 設定備份資料的位置,和下邊的引數有衝突
--dir 指定備份的目錄,和上邊的引數有衝突
