当你已经连接到一个远程的MongoDB数据库服务器（例如，通过mongo连接到192.168.0.184），现在想要在这个会话中连接另一个远程的数据库服务器（192.168.0.197），可以执行如下命令：

 

 

 

 

中的命令mongoimport -h 172.16.8.189 -d fashy -c orderInfo --type csv --file E:\mongodate\1202.csv --headerline --upsert

-d    指定把数据导入到哪一个数据库中

-c    指定把数据导入到哪一个集合中

--type    指定导入的数据类型

--file       指定从哪一个文件中导入数据

--headerline    仅适用于导入csv,tsv格式的数据，表示文件中的第一行作为数据头

--upsert  以新增或者更新的方式来导入数据
