MongoDB is a popular open-source NoSQL database that provides high performance, scalability, and flexibility for modern applications. This guide will show you how to install and configure MongoDB 7.0 on AlmaLinux 9, including essential steps such as configuring system limits, security settings, and user authentication.

Step 1: Create an Instance on Cloud.shape.host

Step 1.1: Access the Dashboard

  1. Log in to Cloud.shape.host.
  2. Click Create, and select Instances.
Shape.host Resources dashboard with Create > Instance highlighted.

Step 1.2: Choose a Datacenter Location

Select a datacenter closest to your target audience, such as New York, London, or Frankfurt.

Shape.host instance form with the data center location selector highlighted.

Step 1.3: Select a Plan

Choose a plan based on the resource needs of your MongoDB installation: Standard, CPU-Optimized, or Memory-Optimized.

Step 1.4: Select an Operating System

Select AlmaLinux 9 as your OS for installing MongoDB.

Shape.host instance form with the operating system image selector highlighted.

Step 1.5: Configure and Launch

  1. Set the Network Type and Authentication Method (SSH key or password).
  2. Click Create Instance.
Shape.host instance form with the Create Instance button highlighted.

Step 1.6: Locate your Instance’s IP

Shape.host Resources dashboard with the server IP address highlighted.

Step 1.7: Access Your Instance

  • SSH (for Linux/macOS):
   ssh root@<your-instance-ip>

Replace <your-instance-ip> with the server’s public IP.

  • PuTTY (for Windows):
    Download PuTTY, enter the public IP, and click Open.

Step 2: Update AlmaLinux Packages

First, ensure your system is up to date:

dnf update -y
Terminal showing DNF/YUM package management commands and output.

Step 3: Install Nano Text Editor

If Nano is not already installed, use this command to install it:

dnf install nano -y
Terminal showing DNF/YUM package management commands and output.

Step 4: Disable Transparent Huge Pages (THP)

Create a systemd service to disable THP:

nano /etc/systemd/system/disable-thp.service

Insert the following configuration:

[Unit]
Description=Disable Transparent Huge Pages (THP)

[Service]
Type=simple
ExecStart=/bin/sh -c "echo 'never' > /sys/kernel/mm/transparent_hugepage/enabled && echo 'never' > /sys/kernel/mm/transparent_hugepage/defrag"

[Install]
WantedBy=multi-user.target
Terminal showing a systemd service unit configuration.

Reload the systemd manager and enable the service:

systemctl daemon-reload
systemctl enable --now disable-thp.service
Terminal showing systemd service management commands or output.
Terminal showing systemd service management commands or output.

Step 5: Set System Limits for MongoDB

Configure system limits by creating a new file for MongoDB:

nano /etc/security/limits.d/mongodb.conf

Insert the following:

mongod soft nproc 64000
mongod hard nproc 64000
mongod soft nofile 64000
mongod hard nofile 64000
Terminal showing system resource limit settings.

Modify the system’s sysctl settings:

nano /etc/sysctl.conf

Add these lines:

fs.file-max = 2097152
vm.max_map_count = 262144
vm.swappiness = 1
Terminal showing kernel network settings and sysctl commands.

Apply the changes:

sysctl -p
Terminal displaying MongoDB system limit values from sysctl.

Optionally, reboot the server to fully apply the changes:

reboot
Terminal showing a shell limit command during MongoDB setup.

Step 6: Configure the MongoDB Repository

Create a repository file for MongoDB:

nano /etc/yum.repos.d/mongodb-org-7.0.repo

Add the following configuration:

[mongodb-org-7.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/9/mongodb-org/7.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://pgp.mongodb.com/server-7.0.asc
Terminal showing the GNU nano editor and configuration text.

Step 7: Install MongoDB

Update the repository list and install MongoDB:

dnf repolist
dnf install mongodb-org mongodb-mongosh
Terminal showing dnf commands or output during Install MongoDB.
Terminal showing the MongoDB shell connection and command output.

Step 8: Start MongoDB Service

Enable and start MongoDB:

systemctl enable --now mongod
systemctl status mongod
Terminal showing systemd service management commands or output.

Step 9: Secure MongoDB

Step 9.1: Disable MongoDB Telemetry

Log in to MongoDB using mongosh:

mongosh

Run the following to disable telemetry:

disableTelemetry()

Step 9.2: Create an Admin User

Switch to the admin database and create an admin user:

use admin
db.createUser({
  user: "myAndeiAdmin",
  pwd: passwordPrompt(),
  roles: [
    { role: "userAdminAnyDatabase", db: "admin" },
    { role: "readWriteAnyDatabase", db: "admin" }
  ]
})
Terminal showing the MongoDB shell connection and command output.

Step 10: Enable Authentication for MongoDB

Uncomment the security option in the MongoDB configuration file:

nano /etc/mongod.conf

Add the following under the security section:

security:
 authorization: enabled
Terminal showing the GNU nano editor and configuration text.

Restart MongoDB to apply the changes:

systemctl restart mongod
Terminal showing systemd service management commands or output.

Step 11: Access MongoDB with Authentication

Log in to MongoDB with authentication:

mongosh

Authenticate with the admin user:

use admin
db.auth("myAndeiAdmin", passwordPrompt())
Terminal showing the MongoDB shell connection and command output.

You have successfully installed and configured MongoDB 7.0 on AlmaLinux 9. This includes disabling THP, setting system limits, enabling authentication, and securing the MongoDB instance. MongoDB is now ready to manage your NoSQL database needs efficiently.
