How to Create MongoDB on VPS

Set Up MongoDB on Your AlexHost VPS: A Step-by-Step Guide

Why run MongoDB on AlexHost? MongoDB’s NoSQL flexibility and JSON-like documents make it a go-to for dynamic apps, and AlexHost’s VPS offers the perfect environment—root access, SSD speed, and robust security—to run it like a champ. This guide walks you through installing, securing, and managing MongoDB on an Ubuntu 20.04 VPS, ensuring a scalable, high-performance database setup.

Prerequisites

Before you start, make sure you have the following:

1. A VPS with root access.
2. Ubuntu 20.04 or a similar Linux distribution.
3. SSH access to your VPS.
4. At least 2GB RAM for MongoDB (recommended).
5. Basic knowledge of the command line interface (CLI) and Linux commands.

Step 1: Update the System

First, make sure your VPS is up to date. Log in over SSH and run the following commands to update your system’s package list and install pending updates:

Once the system has been updated, it is good practice to restart the server to ensure that all updates have been properly applied:

Step 2: Install MongoDB

MongoDB is not included in the default Ubuntu repositories, so you need to add its official repository before installing it. Here’s how to install MongoDB:

Adding the MongoDB Repository

1. Import the MongoDB public GPG key:
   wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -

2. Create a list file for MongoDB:
   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

3. Update your local package list:
   sudo apt update


Installing MongoDB Packages

Now, install the MongoDB packages by running the following command:

This installs MongoDB along with other necessary components (such as mongod, MongoDB daemon).

Step 3: Launch and Activate MongoDB

Once installed, you need to start MongoDB and get it running at startup:

Check the status of MongoDB to verify that it is running:

You should see MongoDB listed as active (running). If everything looks good, you are ready to proceed with the configuration.

Step 4: Secure MongoDB

By default, MongoDB allows unauthenticated access, which is not ideal for a production environment. To secure MongoDB, you must enable authentication.

Create Administrator User

1. First, access the MongoDB shell:
   mongo

2. Switch to the administrator database:
   use manager

3. Create an admin user by running the following command and replacing adminuser and password with the desired username and password:
   db.createUser({
kullanıcı: "adminuser",
pwd: "Şifre",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
})
