mongoDB 數據庫導出與導入
導出數據
mongodump -h IP --port 端口 -u 用戶名 -p 密碼 -d 數據庫 -o 文件存在路徑
如果沒有用戶和密碼，可以去掉-u和-p。
如果導出本機的數據庫，可以去掉-h。
如果是默認端口，可以去掉--port。
如果想導出所有數據庫，可以去掉-d
$>mongodump -h 192.168.164.202 --port 27017 -u dbs -p Abc12345 -d paperfareTable -o /

從遠程192.168.164.202 機子中導到系統根目錄下，跟目錄下會自動生成paperfare文件價,數據的備份是bson,json結尾的數據格式，
導入：
mongoimport -h IP --port 端口 -u 用戶名 -p 密碼 -d 數據庫 -c 表名 --upsert --drop 文件名
$>mongorestore -h 127.0.0.1 --port 27017 -p Abc12345 -d paperfare /paperfare
一下是打出的提示：

我是把數據導入到本地的數據庫中，結束后數據庫中可以直接找的該db。
