Get started with Mongodb

To work on the MongoDB, we need to begin the server first. If you have set the installation path in an environment variable, you can start this from any directory.

Let's create a folder named data having a sub-folder named db where you want to run the server and open cmd as administrator and go to the "c:\data\db".

Write the following command to start the server -

Start Mongodb Server

MongoDB Port

By default, the MongoDB server starts on port 27017. We can also run the MongoDB on different port using --port flag.

mongod --port 27018

MonogoDB Database Directoy

The default directory where MongoDB stores data is under /data/db. We can specify different directory path.

mongod --dbpath /home/mongo/db --port 27018

Write the following command to start the client -

Start Mongodb Client

MongoDB Help

To know more about mongodb daemon, use the --help flag.

mongod --help

MongoDB Application Administration

Sometime, there is need to know all current operations that database is performing. To lists current running operations, use the db.currentOp() command.

	"inprog" : [
			"desc" : "conn5",
			"connectionId" : 5,
			"client" : "",
			"appName" : "MongoDB Shell",
			"clientMetadata" : {
				"application" : {
					"name" : "MongoDB Shell"
				"driver" : {
					"name" : "MongoDB Internal Client",
					"version" : "4.0.10"
				"os" : {
					"type" : "Windows",
					"name" : "Microsoft Windows 10",
					"architecture" : "x86_64",
			"active" : true,
			"currentOpTime" : "2019-08-01T15:32:35.630+0530",
			"opid" : 107720,
			"secs_running" : NumberLong(0),
			"microsecs_running" : NumberLong(42071),
			"op" : "command",
			"ns" : "admin.$cmd.aggregate",
			"command" : {
					"currentOp" : 1,
					"$db" : "admin"
			"numYields" : 0,
			"locks" : {

			"waitingForLock" : false,
			"lockStats" : {

	"ok" : 1

This command is basically used to check the show operations. We can stop any unwanted operation that is running and slowing down the process using killOp() command. Here is the syntax, "opid" is the operation's unique identifier.


Stop MongoDB Server

There is just one command to stop the MongoDB server. This command can run on the admin database only.

> use admin
switched to db admin
> db.shutdownServer()
server should be down...
