导出数据

mongodump -h IP --port 端口 -u 用户名 -p 密码 -d 数据库 -o 文件存在路径

如果没有用户和密码，可以去掉-u和-p。
如果导出本机的数据库，可以去掉-h。
如果是默认端口，可以去掉--port。
如果想导出所有数据库，可以去掉-d

$>mongodump -h 192.168.164.202 --port 27017 -u dbs -p Abc12345 -d paperfareTable -o  /

从远程192.168.164.202 机子中导到系统根目录下，跟目录下会自动生成paperfare文件价,数据的备份是bson,json结尾的数据格式，

导入：

mongoimport -h IP --port 端口 -u 用户名 -p 密码 -d 数据库 -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：
