How to Host MongoDB on Server

Hello Dev, if you are planning to host MongoDB on a server for a project, this article will provide you with a detailed guide on how to do it. MongoDB is a NoSQL database that is widely used in web development because of its flexibility and scalability. Hosting MongoDB on a server will allow you to manage your data more efficiently and securely.

Step 1: Server Requirements

Before you start hosting MongoDB on a server, you need to make sure that your server meets the following requirements:

Requirement	Description
Operating System	Linux, Windows, or MacOS
RAM	Minimum of 2 GB
Processor	Dual-core or higher
Storage	Minimum of 40 GB

Once you have ensured that your server meets these requirements, you can proceed to the next step.

Step 2: Download and Install MongoDB

The next step is to download and install MongoDB on your server. You can download MongoDB from the official website (https://www.mongodb.com/). Follow these steps to install MongoDB:

Step 2.1: Download MongoDB

Download the MongoDB package for your operating system from the official MongoDB website. Once the download is complete, extract the files to a directory on your server.

Step 2.2: Install MongoDB

Follow the installation instructions for your operating system to install MongoDB on your server. Make sure to install all the necessary dependencies and libraries.

Step 2.3: Start MongoDB

Once the installation is complete, start MongoDB by running the following command:

sudo systemctl start mongod

You can also enable MongoDB to start automatically on boot by running the following command:

sudo systemctl enable mongod

Now that MongoDB is installed and running, you can proceed to the next step.

Step 3: Configure MongoDB

The next step is to configure MongoDB to suit your needs. Follow these steps to configure MongoDB:

Step 3.1: Create a MongoDB User

Create a MongoDB user by running the following command:

mongo

Once you are in the MongoDB shell, run the following command to create a user:

use admin

db.createUser({user: "admin", pwd: "password", roles: ["root"]})

Replace “password” in the above command with a strong password of your choice. This user will have administrative privileges, so make sure to choose a strong password.

Step 3.2: Enable Access Control

Enable access control by editing the MongoDB configuration file. Open the file /etc/mongod.conf in your favorite text editor and add the following lines:

security:

authorization: enabled

Save the file and exit the text editor.

Now that MongoDB is configured, you can proceed to the next step.

Step 4: Connect to MongoDB

The final step is to connect to MongoDB from your application. Follow these steps to connect to MongoDB:

Step 4.1: Install MongoDB Driver

Install the MongoDB driver for your programming language. You can find the MongoDB driver for your programming language on the official MongoDB website.

Step 4.2: Connect to MongoDB

Connect to MongoDB from your application by specifying the MongoDB connection string. The connection string should contain the following information:

• Server IP address or hostname
• Port number
• Database name
• Username and password (if access control is enabled)

Here is an example connection string:

mongodb://admin:password@localhost:27017/mydatabase

Replace “admin” and “password” in the above connection string with the username and password of your MongoDB user. Also replace “mydatabase” with the name of your MongoDB database.

Now you are connected to MongoDB and you can start using it in your application.
