Deploy Memgraph

Memgraph is a high-performance, in-memory graph database built for real-time analytics, streaming data, and complex relationship queries. It is fully compatible with the Cypher query language, making it easy for developers familiar with Neo4j-style graph workflows to build and deploy graph-powered applications.

Memgraph is optimized for use cases such as fraud detection, recommendation engines, network analysis, and real-time decision systems. With native support for streaming data pipelines and advanced graph algorithms, Memgraph enables low-latency processing and scalable graph workloads in production environments.

Deploying a Quick Deploy App

The Linode Marketplace lets you easily deploy software on a Compute Instance using Cloud Manager. See Get Started with Marketplace Apps for complete steps.

1. Log in to Cloud Manager and select the Marketplace link from the left navigation menu. This displays the Linode Create page with the Marketplace tab pre-selected.

2. Under the Select App section, select the app you would like to deploy.

3. Complete the form by following the steps and advice within the Creating a Compute Instance guide. Depending on the Marketplace App you selected, there may be additional configuration options available. See the Configuration Options section below for compatible distributions, recommended plans, and any additional configuration options available for this Marketplace App.

4. Click the Create Linode button. Once the Compute Instance has been provisioned and has fully powered on, wait for the software installation to complete. If the instance is powered off or restarted before this time, the software installation will likely fail.

To verify that the app has been fully installed, see Get Started with Marketplace Apps > Verify Installation. Once installed, follow the instructions within the Getting Started After Deployment section to access the application and start using it.

Configuration Options

• Recommended plan: Shared CPU 4GB or Dedicated CPU 4GB (or larger for production workloads)

Memgraph Options

• Memgraph User (required): This is the user for your Memgraph database.

• Email address (for DNS SOA email) (optional): If you are deploying this with a domain, it requires an email address to add to the SOA record.

Limited Sudo User

You need to fill out the following fields to automatically create a limited sudo user, with a strong generated password for your new Compute Instance. This account will be assigned to the sudo group, which provides elevated permissions when running commands with the sudo prefix.

• Limited sudo user: Enter your preferred username for the limited user. No Capital Letters, Spaces, or Special Characters.

  Locating The Generated Sudo Password

  A password is generated for the limited user and stored in a .credentials file in their home directory, along with application specific passwords. This can be viewed by running: cat /home/$USERNAME/.credentials

  For best results, add an account SSH key for the Cloud Manager user that is deploying the instance, and select that user as an authorized_user in the API or by selecting that option in Cloud Manager. Their SSH pubkey will be assigned to both root and the limited user.

• Disable root access over SSH: To block the root user from logging in over SSH, select Yes. You can still switch to the root user once logged in, and you can also log in as root through Lish.

  Accessing The Instance Without SSH

  If you disable root access for your deployment and do not provide a valid Account SSH Key assigned to the authorized_user, you will need to login as the root user via the Lish console and run cat /home/$USERNAME/.credentials to view the generated password for the limited user.

Getting Started After Deployment

Obtain the Credentials

When deployment completes, the system automatically generates credentials to administer your Memgraph instance. These are stored in the limited user’s .credentials file.

1. Log in to your Compute Instance using one of the methods below:

   • Lish Console: Log in to Cloud Manager, click Linodes, select your instance, and click Launch LISH Console. Log in as root. To learn more, see Using the Lish Console.
   • SSH: Log in to your instance over SSH using the root user. To learn how, see Connecting to a Remote Server Over SSH.

2. Run the following command to access the contents of the .credentials file:

   cat /home/$USERNAME/.credentials

Connecting to Memgraph

Memgraph listens on the Bolt protocol by default on port 7687.

You can connect using:

• The mgconsole CLI installed on the server
• Any Bolt-compatible driver (Python, JavaScript, Go, Java, etc.)

Connect using mgconsole locally on the server

See the below example for how to use the mgconsole CLI to connect to Memgraph while logged into your instance:

mgconsole --host 127.0.0.1 --port 7687 --username MEMGRAPH_USER --password YOUR_PASSWORD

Basic Verification Query

After logging in using mgconsole, you can run the following to output the Memgraph version and Memgraph edition of your deployment:

CALL dbms.components() YIELD name, version, edition
RETURN name, version, edition;

Now that you’ve accessed your Memgraph instance, check out the official Memgraph documentation to learn how to further use your instance.
