MEAN Stack

Deploy a MEAN stack, a JavaScript-based software bundle (MongoDB, Express, Angular, Node.js) for building web applications.

1. Deploy a MEAN Stack

Estimated deployment time: 2–5 minutes

Follow the deployment instructions from the Get started section to configure the app, deploy it, and verify software installation.

For information on the app-specific configurations, see the Configuration options section.

Software included

Software installed on your Linode when deploying the app.

Package	Description
MongoDB	A document database used to persist the application’s data.
Express	A web application framework.
Angular	A JavaScript frontend framework with CLI.
Node.js	A runtime environment.
NGINX	A web server.
UFW	Uncomplicated Firewall. A firewall utility configured to allow traffic on ports 22, 80, and 443 for IPv4 and IPv6. All other ports have these firewall rules: deny (incoming), allow (outgoing).

Base distribution and plan

Supported distribution: Ubuntu 24.04 LTS
Recommended plans: Use a 1GB Shared CPU Compute Instance or larger, depending on the number and size of sites you plan to host.

Configuration options

Configure the required options to deploy your instance. For additional customization, add advanced options.

The table maps the Cloud Manager UI fields to their corresponding API/CLI keys (stackscript_data) required for automated deployments.

StackScript ID: 611895

UI field	API/CLI key	Description
Required options
Limited sudo user	`user_name`	Your preferred username for the limited sudo user entered without any capital letters, spaces, or special characters. When adding a limited sudo user, the user is created with a strong generated password for your new Linode instance, and the account is assigned to the `sudo` group, which provides elevated permissions when running commands with the `sudo` prefix. Note: For easier and more secure access with the sudo user, add an account SSH key for the Cloud Manager user during deployment and select that user as an `authorized_user`. Their SSH pubkey will be assigned to both the root and limited user.
Admin Email (for Let's Encrypt SSL certificate)	`soa_email_address`	The email address used for generating SSL certificates.
Advanced options
Disable root access over SSH	`disable_root`	Applies to a limited sudo user. To block the root user from logging in over SSH, select Yes. Defaults to No. Note: When you disable the root user from logging in over SSH and don't provide a valid account SSH key assigned to the `authorized_user`, you can still switch to the root user. To do that, log in as root via the Lish console and run `cat /home/$USERNAME/.credentials` to view the generated password for the limited sudo user.
Linode API token	`token_password`	Applies to a custom domain. The Linode API token if you want to use Linode's DNS Manager to manage DNS records for your custom domain. Follow Manage personal access tokens to get your token on your account with `Read/Write` access to `Domains`. If you provide the token along with the subdomain and domain, the installation attempts to create DNS records via the Linode API. If you don't provide the token, you need to manually configure your DNS records through your DNS provider and point them to the IP address of the new instance.
Subdomain	`subdomain`	Applies to a custom domain. The subdomain you want to use, like `blog` for `blog.example.com`. Use it only if you specify a Domain.
Domain	`domain`	Applies to a custom domain. The domain name you want to use, like `example.com`. Use it only if you specify a Linode API token.
Optional data exporter Add-ons	`add_ons`	An option to include add-ons for your deployment. Possible values are: none (default) newrelic node_exporter mysqld_exporter

Notes:

After the app deployment completes, the password for your limited sudo user is generated and stored in the .credentials file in the home directory, along with application-specific passwords. Log in to your instance as root through the Lish console or SSH, then run cat /home/$USERNAME/.credentials to view its contents.

You can automatically configure a custom domain (optional) during deployment. To do that:

Configure your domain to use Linode's name servers via your registrar. See Configure your domain's authoritative name servers for details.

Once you complete that, specify the Linode API token, subdomain, and domain for the app in Cloud Manager or via API/CLI/Terraform.

Use API, CLI, or Terraform

In addition to deploying the app to a new Linode instance via Cloud Manager, you can also use the Linode API, CLI, or Terraform. When running the operation, you need to provide the StackScript ID, supported Linux distribution, and app-specific fields along with the standard Linode deployment configurations.

Note: Generate a personal access token to authenticate your API, CLI, or Terraform requests.

  stackscript_data = {
    "user_name"         = "jsmith"
    "soa_email_address" = "jsmith@example.com"
  }
}

2. Use the MEAN Stack

After deployment, a sample application runs with the Express backend on port 5000 and the Angular frontend served by NGINX through your custom domain or rDNS domain over ports 80 and 443.

Access the application files

The MEAN stack components are organized as follows:

Angular frontend: /var/www/[domain]
Express backend: /var/www/[domain]/backend

You can access these components within the command line by logging in to your instance through the Lish console or SSH.

To inspect the Express server:

cd /var/www/[domain]/backend
cat server.js

To view the Angular frontend files:

cd /var/www/[domain]
ls

Access the MEAN app

Open your web browser and navigate to https://[domain], replacing [domain] with your custom domain or the instance's rDNS domain, such as 192-0-2-1.ip.linodeusercontent.com.

See the Manage IP addresses on a Linode guide for information on viewing rDNS.
