如何打开 mongo-db 转储文件？

Question

I have a .dump file (8GB) which is a mongo database that I need to work with. I'm working with Robo 3T.

I've tried:

• a) menu options in robo gui
• b) mongorestore --db cert-db certctream.dump command, got error (using certctream without the extension didn't work as well)

Failed: file certctream.dump does not have .bson extension

What am I missing?

Answer 1

解决方案：

mongoimport --db <new_db_name> --host localhost:27017 path_to_dump_file

Answer 2

1. To import a mongo collection:

    mongoimport -d database_name -c collection_name

   In this case, collection_name would be the JSON file for the corresponding collection.

2. To import a mongo database:

    mongorestore -d database_name

   In this case, database_name would be a folder.

To restore from a .dump file you need to use the archive argument:

mongorestore --archive=mydump.dump

GOTCHA
The dump may have also been gzipped, in which case you'll get:
Failed: stream or file does not appear to be a mongodump archive

In this case, try adding --gzip as it might do the job:

mongorestore --gzip --archive=mydump.dump
