Start MongoDB Server

Start MongoDB Server from Command Prompt

Windows Users

Assuming that you installed MongoDB Server with default options, especially the installation folder as C:\Program Files\MongoDB\Server\4.0. Inside this folder, you have the bin directory containing mongod.exe.

Also assuming that the database path is: C:\data\db\

To start MongoDB Server in Windows, start Mongo Daemon (mongod.exe) using the following command:

 C:\> "C:\Program Files\MongoDB\Server\4.0\bin\mongod.exe"

Note that the program we are running is mongod.exe and not mongo.exe.

mongo.exe is used to start Mongo Shell, while mongod.exe is used to run Mongo Server.

C:\>"C:\Program Files\MongoDB\Server\4.0\bin\mongod.exe"

The MongoDB Server has started successfully.

From the messages logged to the console, you can observe that:

• Mongo Server is started as a process with process id (pid): 11716.
• Mongo Server is listening at the port number: 27107. You can see at the end of logs [initandlisten] waiting for connections on port 27017.
• Mongo Server is using the database present at the location C:\data\db\.

Do not close this Command Prompt window.

Now, you can connect to this server as clients from other Command Prompt windows.
