MongoDB is a popular NoSQL database that provides high performance, high availability, and easy scalability. In this guide, we will walk you through how to install and use MongoDB on Ubuntu 20.04 LTS. Whether you’re hosting your database on a or another cloud platform, MongoDB is a robust choice for modern applications.<\/p>\n
Before starting, ensure you have the following:<\/p>\n
MongoDB is not available in the default Ubuntu repositories, so you need to add the official MongoDB repository to your server. Start by importing the GPG key for the official MongoDB repository:<\/p>\n
sudo apt update\r\nwget -qO - https:\/\/www.mongodb.org\/static\/pgp\/server-4.4.asc | sudo apt-key add -<\/code><\/pre>\nNext, add the MongoDB repository:<\/p>\n
echo \"deb [ arch=amd64,arm64 ] https:\/\/repo.mongodb.org\/apt\/ubuntu focal\/mongodb-org\/4.4 multiverse\" | sudo tee \/etc\/apt\/sources.list.d\/mongodb-org-4.4.list<\/code><\/pre>\nStep 2: Install MongoDB<\/h2>\n
Once the repository is added, update the package list and install MongoDB:<\/p>\n
sudo apt update\r\nsudo apt install -y mongodb-org<\/code><\/pre>\nStep 3: Start MongoDB<\/h2>\n
After installation, start the MongoDB service and enable it to start at boot:<\/p>\n
sudo systemctl start mongod\r\nsudo systemctl enable mongod<\/code><\/pre>\nStep 4: Verify MongoDB Installation<\/h2>\n
You can verify that MongoDB is running by checking its status:<\/p>\n
sudo systemctl status mongod<\/code><\/pre>\nYou should see output indicating that MongoDB is active and running.<\/p>\n
Step 5: Access the MongoDB Shell<\/h2>\n
To start using MongoDB, you can access the MongoDB shell by running:<\/p>\n
mongo<\/code><\/pre>\nThis will bring you to the MongoDB shell, where you can run database commands.<\/p>\n
Step 6: Basic MongoDB Commands<\/h2>\n
Here are a few basic MongoDB commands to get you started:<\/p>\n
\n\n- Create a new database:<\/strong> In MongoDB, databases are created automatically when you insert data. To switch to a new database, use the following command:<\/li>\n<\/ul>\n<\/ul>\n
use mydatabase<\/code><\/pre>\n\n\n- Create a collection and insert data:<\/strong> Collections are created automatically when you insert data. To create a new collection and insert a document, use:<\/li>\n<\/ul>\n<\/ul>\n
db.mycollection.insert({name: \"John\", age: 30})<\/code><\/pre>\n\n\n- Find data in a collection:<\/strong> To find data stored in a collection, use the
find()<\/code> method:<\/li>\n<\/ul>\n<\/ul>\ndb.mycollection.find()<\/code><\/pre>\nStep 7: Secure MongoDB (Optional)<\/h2>\n
By default, MongoDB allows connections only from localhost<\/code>. To allow remote access, you can modify the MongoDB configuration file:<\/p>\nsudo nano \/etc\/mongod.conf<\/code><\/pre>\nFind the line that starts with bindIp<\/code> and modify it to include your server\u2019s IP address:<\/p>\nbindIp: 127.0.0.1, your-server-ip<\/code><\/pre>\nAfter making this change, restart MongoDB:<\/p>\n
sudo systemctl restart mongod<\/code><\/pre>\nConclusion<\/h2>\n
By following these steps, you have successfully installed and started using MongoDB on Ubuntu 20.04 LTS. Whether you’re hosting your MongoDB database on a , Microsoft SQL VPS Windows<\/a>, or another Windows VPSVirtual Private Server Hosting<\/a> solution, MongoDB provides a scalable and flexible NoSQL database for your applications.<\/p>\n
