Running Mongo Deamon and Starting Database

To start working on the mongo database, we would first want the installed mongo package to run as a service .These deamons will serve as a server/platform for our database instances to run.This deamon is represented by "mongod" and can be initiated by running mongod.exe or mongod.sh scripts in windows/unix .


Follow below steps to run a mongo deamon as a service in the server:

1. Start MongoDB

sudo service mongod start


2. Verify that MongoDB has started successfully

[initandlisten] waiting for connections on port 27017


3. Stop MongoDB.

sudo service mongod stop


4. Restart MongoDB

sudo service mongod restart


Each database instances will be running on unique ports .Default port for mongo database is 27017.

Run the below command to start a database instance on the server with the specific parameters of your requirement:

mongod --config mongo.conf


mongo.conf is a config file containing the different startup parameters provided as input to the mongod deamon.Below is an example of mongod.conf file containing all the general parameters used for a database startup:


# mongod.conf
