Getting Started with MongoDB on macOS
MongoDB, a popular NoSQL database, can be easily installed and run on your macOS machine. This guide will walk you through the installation process and demonstrate how to start and manage your MongoDB instance.
Installing MongoDB on macOS
The easiest way to install MongoDB is by using its official package manager, brew. If you haven't already, install Homebrew using the instructions found on the official website: https://brew.sh/
Once Homebrew is installed, you can install MongoDB with the following command:
brew install mongodb-community
This command will download and install the latest stable version of MongoDB.
Starting and Accessing MongoDB
After the installation is complete, you can start the MongoDB server with the following command:
mongod
This will launch MongoDB in the foreground. You can check if it is running by accessing the MongoDB shell:
mongo
You should see the MongoDB shell prompt, indicating that you are connected to your local MongoDB instance.
Important Note: If you are using an older version of MongoDB (prior to 4.0), you may need to use the mongod --dbpath
option to specify the location of your data directory. By default, the data directory is located at /data/db
.
Managing MongoDB
You can interact with your MongoDB instance using the MongoDB shell. Here are a few basic commands:
show dbs
: Lists all existing databases.use <database_name>
: Switches to the specified database.db.collection.find()
: Displays all documents in the specified collection.db.collection.insertOne({...})
: Inserts a new document into the collection.db.collection.updateOne({...},{...})
: Updates an existing document in the collection.
For more advanced MongoDB operations and database management tasks, consider using the MongoDB Compass application. It's a free, graphical interface that offers a user-friendly way to interact with MongoDB, manage collections, and visualize data. You can download it from the official MongoDB website: https://www.mongodb.com/products/mongodb-compass
Running MongoDB in the Background
While running MongoDB in the foreground is convenient for testing, you'll likely want to run it in the background for production use. This can be achieved using the &
symbol after the mongod
command:
mongod &
This will start MongoDB in the background and allow you to continue using your terminal.
