I'm new to MongoDB. I currently have a dump of a mongo db (i.e. directory of .bson files) and am trying to import that into mongo.
I installed mongo as per the instructions on http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/.
I'm currently trying to test starting a local mongo instance by running mongod --dbpath /path/to/my/mongodata (which is an empty directory).
I get the following in stdout:
Thu Sep 20 09:46:01 [initandlisten] MongoDB starting : pid=1065 port=27017 dbpath=/path/to/my/mongodata/ 64-bit host=dhcp-18-111-28-92.dyn.mit.edu

Thu Sep 20 09:46:01 [initandlisten] waiting for connections on port 27017
At this point, it just hangs there and does nothing. Seems like it's waiting for something to happen on localhost, but I don't know mongo well enough to understand what's going on. Any help?
There is nothing wrong, you have started the server, it is running and listening on port 27017. Now you can start to interact with the server, for example just open a new terminal tab and run mongo ,which will open mongo's interactive console and connects to the default server(localhost:27017)
If you want to run mongod as a background process (to get back the console) you can use --fork command option. This requires you to use some sort of logging.
Eg. mongod --dbpath /path/to/my/mongodata --fork --logpath /path/to/my/mongod.log
If you want to restore a bsonexport you will probably use the mongorestore command
Add the below in the configuration file and call it using monogd, make sure your bind_ip is configured as per your requirement and use the below link to add few more replica sets:
https://docs.mongodb.org/manual/tutorial/deploy-replica-set/
Step 1:
vi /etc/mongod.conf
replication: replSetName: rs01
Step 2:
mongod --config /etc/mongod.conf
Output:
warning: bind_ip of 0.0.0.0 is unnecessary; listens on all ips by default
about to fork child process, waiting until server is ready for connections.
forked process: 30012
child process started successfully, parent exiting
You need to follow the below 2 steps:
Step 1:
Open CMD and enter mongod. This will run the mongo server
Step 2: Open another Command Prompt, move to the location of file and type
mongorestore -d db_name -c collection_name file.bson
Copied from official documentation
This starts the main MongoDB database process. The waiting for connections message in the console output indicates that the mongod.exe process is running successfully.
https://docs.mongodb.com/manual/tutorial/install-mongodb-on-windows/
pressing ctrl+c or ctrl+z will stop mongod service,and just run sudo servie mongod start
