Install MongoDB in Linux: Step-by-Step Guide for Easy Installation
Are you looking to install MongoDB on your Linux system? Look no further! This comprehensive step-by-step guide will walk you through the entire installation process, making it easy for you to get MongoDB up and running in no time. Whether you’re a beginner or an experienced user, this guide will provide you with all the information you need to successfully install MongoDB on your Linux machine.
1. Update the package manager
Before we begin the installation process, it’s important to update the package manager on your Linux system. This ensures that you have the latest version of all the software packages installed on your machine. To update the package manager, open the terminal and run the following command:
sudo apt update
This command will update the package manager and fetch the latest information about available software updates.
2. Install MongoDB
Once the package manager is updated, you can proceed with the installation of MongoDB. To install MongoDB, run the following command in the terminal:
sudo apt install mongodb
This command will download and install the MongoDB package on your Linux system.
3. Start the MongoDB service
After the installation is complete, you need to start the MongoDB service. This will enable you to use MongoDB on your Linux machine. To start the MongoDB service, run the following command:
sudo systemctl start mongodb
This command will start the MongoDB service and make it available for use.
4. Enable MongoDB to start on boot
If you want MongoDB to start automatically every time you boot up your Linux system, you can enable it to do so. To enable MongoDB to start on boot, run the following command:
sudo systemctl enable mongodb
This command will configure MongoDB to start automatically on system boot.
5. Verify the status of MongoDB
To ensure that MongoDB is running correctly on your Linux system, you can check its status. To do this, run the following command:
sudo systemctl status mongodb
This command will display the current status of the MongoDB service, including whether it is running or not.
6. Access the MongoDB shell
Now that MongoDB is installed and running, you can access the MongoDB shell. The MongoDB shell is a command-line interface that allows you to interact with the MongoDB database. To access the MongoDB shell, simply run the following command:
mongo
This command will open the MongoDB shell, where you can execute various commands and perform operations on the MongoDB database.
7. Create a new database
Once you are in the MongoDB shell, you can create a new database. A database is a container for collections, which in turn store documents. To create a new database, use the following command:
use <database_name>
Replace <database_name> with the desired name for your database. This command will create a new database with the specified name.
8. Create a new collection
Within a database, you can create collections to organize your data. A collection is a group of documents that share a similar structure. To create a new collection, use the following command:
db.createCollection("<collection_name>")
Replace <collection_name> with the desired name for your collection. This command will create a new collection with the specified name within the current database.
9. Insert documents into the collection
Now that you have a database and a collection, you can start inserting documents into the collection. A document is a set of key-value pairs that represent your data. To insert a document into the collection, use the following command:
db.<collection_name>.insertOne({<document>})
Replace <collection_name> with the name of the collection where you want to insert the document. Replace <document> with the actual document you want to insert. This command will insert the specified document into the collection.
10. Query the collection
Once you have inserted documents into the collection, you can query the collection to retrieve data. A query is a request for specific data from the collection. To query the collection, use the following command:
db.<collection_name>.find()
Replace <collection_name> with the name of the collection you want to query. This command will retrieve all the documents from the specified collection.
11. Exit the MongoDB shell
When you are done working with the MongoDB shell, you can exit it. To exit the MongoDB shell, simply run the following command:
exit
This command will exit the MongoDB shell and return you to the regular terminal.
12. Stop the MongoDB service
If you need to stop the MongoDB service for any reason, you can do so using the following command:
sudo systemctl stop mongodb
This command will stop the MongoDB service, making it unavailable until you start it again.
13. Uninstall MongoDB
If you decide that you no longer need MongoDB on your Linux system, you can uninstall it. To uninstall MongoDB, run the following command:
sudo apt remove mongodb
This command will remove the MongoDB package from your Linux system.
14. Remove MongoDB data directory
When you uninstall MongoDB, the data directory associated with it is not automatically removed. If you want to completely remove MongoDB and its data, you can delete the data directory. To do this, run the following command:
sudo rm -r /var/lib/mongodb
This command will remove the MongoDB data directory from your Linux system.
15. Remove MongoDB log directory
In addition to the data directory, MongoDB also creates a log directory. If you want to remove the log directory as well, run the following command:
sudo rm -r /var/log/mongodb
This command will remove the MongoDB log directory from your Linux system.
Now that you have successfully installed MongoDB on your Linux system, you can start using it to store and retrieve data. Whether you’re a developer, a data analyst, or a system administrator, MongoDB provides a powerful and flexible solution for managing your data. By following this step-by-step guide, you can easily install MongoDB and get started with your projects.
