Welcome, Dev! In this article, we will guide you on how to host MongoDB on your own server effectively. MongoDB is a document-oriented database management system that has gained enormous popularity in recent years. It’s a powerful tool that can handle complex data and ensure quick access to the data stored within it. MongoDB can be a valuable addition to your website, web application, or software project. However, hosting MongoDB on your own server can be a bit challenging. That’s why we’re here to help you with the process.
Step 1: Choose the Right Hardware
Before you begin hosting MongoDB on your own server, it is vital to select the right hardware to run it. MongoDB requires a server with high RAM capacity and fast CPU to handle large volumes of data. A server with SSD storage is also recommended. Below is a table showing the recommended hardware configuration for hosting MongoDB on your own server.

Factors to Consider While Choosing the Right Hardware
Several factors need to be considered while selecting the right hardware to host MongoDB on your own server. These include the following:
- The size of your data
- The number of requests your server will handle
- The complexity of your queries
- The level of redundancy and high availability required
Considering these factors will help you choose the right hardware configuration to ensure that your MongoDB runs smoothly on your own server.
Step 2: Install MongoDB on Your Server
Installing MongoDB on your server is the next step in hosting MongoDB on your own server. MongoDB provides an official installer package for different operating systems. In this section, we will guide you on how to install MongoDB on Ubuntu, one of the most popular operating systems for hosting servers. Below are the steps to follow:
Step 2.1: Import the MongoDB public GPG key
Run the following command to import the MongoDB public GPG key:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
Step 2.2: Create a list file for MongoDB
Create a list file for MongoDB in the /etc/apt/sources.list.d/ directory using the following command:
echo "deb http://repo.mongodb.org/apt/ubuntu $(lsb_release -sc)/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
Step 2.3: Reload the local package database
Reload your local package database with the following command:
sudo apt-get update
Step 2.4: Install MongoDB
Finally, install the MongoDB package with the following command:
sudo apt-get install -y mongodb-org
Frequently Asked Questions

Q5: How do I secure my MongoDB installation?
A5: There are several measures you can take to secure your MongoDB installation. These include enabling authentication, enabling encryption, and restricting access to your MongoDB instance.
Step 3: Configure MongoDB on Your Server
After installing MongoDB on your server, the next step is to configure it. MongoDB requires several configuration parameters, such as port number, data directory, and log directory, to run. Below is a sample configuration file showing the recommended configuration parameters for MongoDB:
systemLog:destination: filepath: /var/log/mongodb/mongod.loglogAppend: truestorage:dbPath: /var/lib/mongodbjournal:enabled: trueprocessManagement:fork: truenet:port: 27017security:authorization: enabled
Explaining the Configuration Parameters
The configuration file above has several configuration parameters that need to be explained. These are as follows:
- systemLog: This section defines the log directory and file for MongoDB.
- storage: This section defines the data directory for MongoDB and enables journaling.
- processManagement: This section enables MongoDB to fork as a daemon process.
- net: This section defines the port number on which MongoDB listens for incoming connections.
- security: This section enables authentication for MongoDB.
Step 4: Start MongoDB on Your Server
Starting MongoDB on your server is the next step in hosting MongoDB on your own server. You can start MongoDB by running the following command:
sudo systemctl start mongod
Verifying MongoDB is Running
You can verify that MongoDB is running on your server by running the following command:
sudo systemctl status mongod
If MongoDB is running, you should see output similar to the following:
● mongod.service - MongoDB Database ServerLoaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset: enabled)Active: active (running) since Mon 2021-11-22 10:12:45 UTC; 2h 38min agoDocs: https://docs.mongodb.org/manual Main PID: 12345 (mongod)Tasks: 23 (limit: 1168)Memory: 85.1MCPU: 2.132sCGroup: /system.slice/mongod.service└─12345 /usr/bin/mongod --config /etc/mongod.conf
Step 5: Connect to MongoDB
The final step in hosting MongoDB on your own server is to connect to it. There are several ways to connect to MongoDB, but the most common method is by using the MongoDB shell. Below are the steps to connect to MongoDB using the MongoDB shell:
Step 5.1: Start the MongoDB shell
Start the MongoDB shell by running the following command:
mongo
Step 5.2: Connect to Your MongoDB Instance
Connect to your MongoDB instance by running the following command:
mongo --host--port 27017
Replace
Step 5.3: Authenticate to MongoDB
If you enabled authentication in your MongoDB configuration, you will need to authenticate to MongoDB before you can start using it. To authenticate to MongoDB, run the following command:
use admindb.auth("admin_username", "admin_password")
Replace admin_username and admin_password with the username and password you set up for MongoDB authentication.
