How to Connect Shell to MongoDB

Connecting MongoDB Shell to your MongoDB instance is a crucial step to start interacting with your databases and collections. Follow these steps to connect MongoDB Shell to MongoDB:

• Open your Terminal or Command Prompt: First, open your terminal or command prompt on your computer. You can usually find these applications in your operating system’s applications or utilities folder.
• Navigate to MongoDB Shell: If you installed MongoDB Shell using the default settings, you should be able to access it from anywhere in your terminal or command prompt. However, if you encounter any issues, you can navigate to the MongoDB Shell installation directory using the cd command. For example

cd /path/to/mongodb/bin

• Initiate MongoDB Shell: Once you’re in the appropriate directory, you can initiate MongoDB Shell by typing the following command and pressing Enter

mongo

• Connect to MongoDB Instance: By default, this command will attempt to connect to a MongoDB instance running on your local machine using the default settings (localhost:27017). If your MongoDB instance is running on a different host or port, or if you require authentication, you can specify the connection string as follows

mongo "mongodb://username:password@host:port/database"

Replace the placeholders with your specific connection details:

• username: Your MongoDB username
• password: Your MongoDB password
• host: The hostname or IP address of your MongoDB server
• port: The port number on which MongoDB is running (default is 27017)
• database: (Optional) The name of the database you want to connect to

If authentication is not required, you can omit the username and password from the connection string.

• Verify Connection: After executing the command, MongoDB Shell will attempt to establish a connection to the specified MongoDB instance. If the connection is successful, you’ll see the MongoDB Shell prompt (>) indicating that you’re connected and ready to execute commands.
