How to import dumped Mongodb?
提问by YogiZoli
Dumped a MongoDB successfully:
成功转储 MongoDB：
$ mongodump -h ourhost.com:portnumber -d db_name01 -u username -p
I need to import or export it to a testserver and have struggle with it, please help me figure out.
我需要将它导入或导出到测试服务器并且遇到困难，请帮我弄清楚。
I tried some ways:
我尝试了一些方法：
$ mongoimport -h host.com:port -c dbname -d dbname_test -u username -p
connected to host.
Password: ...
Gives this error:
给出这个错误：
assertion: 9997 auth failed: { errmsg: "auth fails", ok: 0.0 }
$ mongoimport -h host.com:port -d dbname_test -u username -p
Gives this error:
给出这个错误：
no collection specified!
How to specify which collection to use? What should I use for -d? What I'd like to upload or what I want to use as test out there? I would like to import the full DB not only collection of it.
如何指定使用哪个集合？-d 我应该用什么？我想上传什么或我想用什么作为测试？我想导入完整的数据库，而不仅仅是它的集合。

The counterpart to mongodumpis mongorestore(and the counterpart to mongoimportis mongoexport) -- the major difference is in the format of the files created and understood by the tools (dumpand restoreread and write BSONfiles; exportand importdeal with text file formats: JSON, CSV, TSV.
对方给mongodump的mongorestore（以及对应于mongoimport为mongoexport） -的主要区别是在创造和理解这些工具中的文件的格式（dump与restore读写BSON文件;export并import用文本文件格式的交易：JSON，CSV，TSV。
If you've already run mongodump, you should have a directory named dump, with a subdirectory for each database that was dumped, and a file in those directories for each collection. You can then restore this with a command like:
如果您已经运行了mongodump，您应该有一个名为dump的目录，每个转储的数据库都有一个子目录，每个集合在这些目录中都有一个文件。然后，您可以使用以下命令恢复它：
mongorestore -h host.com:port -d dbname_test -u username -p password dump/dbname/
Assuming that you want to put the contents of the database dbnameinto a new database called dbname_test.
假设您要将数据库的内容dbname放入一个名为dbname_test.

When you do a mongodumpit will dump in a binary format. You need to use mongorestoreto "import" this data.
当您执行 a 时mongodump，它将以二进制格式转储。您需要使用mongorestore来“导入”这些数据。
Mongoimportis for importing data that was exported using mongoexport
Mongoimport用于导入使用导出的数据 mongoexport

You may have to specify the authentication database
您可能必须指定身份验证数据库
mongoimport -h localhost:27017 --authenticationDatabase admin -u user -p -d database -c collection --type csv --headerline --file awesomedata.csv
