Data export and import in MongoDB

MongoDB's data import method is similar to that of MySQL.

------------------------------------------------------------------------------

Data export:

Mongodump -- Host XXXXX -- Port 27017 -- username -- password passwd -- out/mnt/dbbak

In this way, the data is remotely stored in the local/mnt/dbbak.

The password uses the admin user name and password.

It can also be used as a local data backup.

Data Import:

If the database to be imported is empty, do not add verification information at startup,

Mongod -- dbpath/mnt/dbdata -- logpath/mnt/dblog/MongoDB. log -- fork

Then run the import command

Mongorestore/mnt/dbbak/

In this way, all the data is imported and the command with verification is restarted.

Mongod -- dbpath/mnt/dbdata -- logpath/mnt/dblog/MongoDB. log -- auth -- fork

In this way, you can simply export and import data.
