Setting up remote connections

In the configuration file, you will

bindIp: 127.0.0.1

Comment out (that is, the first addition to the sentence # )

#bindIp: 127.0.0.1

Restart database

sudo service mongod restart

Change Data Catalog

The default data store directory is /var/lib/mongodb , assuming our destination path is/home/mongodb

Close the database

sudo service mongod stop

Set the item to the destination path in the configuration file storage.dbPath , as modified below

storage：  dbPath: /home/mongodb

Copy the files from the original directory to the new directory:

/var/bin/mongodb/* /home/mongodb/

To mongod.lock start a database after deleting a file

sudo rm /home/mongodb/mongod.locksudo service mongod start

Testing remote connections

Attention:

When your mongo command error occurs, when the connection fails, try deleting the file in the Datastore directory and restart the mongod.lock MongoDB database
