将mongo数据库复制到本地

Question

I need to copy a mongo database from my Mongo Cloud Atlas and use it with my meteor app locally, but after doing the following steps, db.users.find().count() still reports the "older" database count not the new one I thought I correctly restored after mongodump. Any ideas?

dump from the Atlas cluster, run from the app parent directory:
mongodump --host Cluster0-shard-0/cluster0-shard-00-00-oko1k.mongodb.net:27017,cluster0-shard-00-01-oko1k.mongodb.net:27017,cluster0-shard-00-02-oko1k.mongodb.net:27017 --ssl --username myname --password myPswd --authenticationDatabase admin --db dbName

Terminal reports lines like:
2018-03-17T05:03:57.462+1100 writing dbName.tempLinksGroupsCol to 2018-03-17T05:03:57.465+1100 done dumping dbName.commonCol (1 document)

Confirm the presence of a dump directory which contains a directory "dbName".

copy data from newly dumped dbName to my local dbName by running this command from the app parent directory:

mongorestore --maintainInsertionOrder -h 127.0.0.1 --port 3001 --drop -d dbName dump/dbName

I get lines like:
2018-03-17T05:21:48.826+1100 finished restoring dbName.cronHistory (0 documents) 2018-03-17T05:21:48.826+1100 done switch to the app directory and run the command:
meteor open a new terminal and run the command:
meteor mongo

issue the command from the mongo shell:
db.users.find().count()

Still reports the old count not the new one from the restored database.

try:

mongorestore -h 127.0.0.1 --port 3001 --drop

I see that you are not providing correct path of dump. just mention path of dump folder.

See documentation for mongorestore https://docs.mongodb.com/manual/reference/program/mongorestore/
