Deploy Redis through the Linode Marketplace

Redis is an open-source, in-memory, data-structure store, with the optional ability to write and persist data to a disk, which can be used as a key-value database, cache, and message broker. Redis features built-in transactions, replication, and support for a variety of data structures such as strings, hashes, lists, sets, and others.

The One-Click App for Redis installs Redis version 7.2.7.

Deploying a Marketplace 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

• Supported distributions: Ubuntu 24.04 LTS
• Suggested minimum plan: All plan types and sizes can be used, though consider using a High Memory Compute Instance for larger databases in a production environment.

Redis Options

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.

Self Signed SSL/TLS Options

• Country or Region: Enter the country or region for you or your organization.

• State or Province: Enter the state or province for you or your organization.

• Locality: Enter the town or other locality for you or your organization.

• Organization: Enter the name of your organization.

• Email Address: Enter the email address you wish to use for your certificate file.

• CA Common Name: Enter a common name to be shared as the authority for all SSL certificates, for example Redis CA.

• Client Count: Generate up to ten SSL certificates for external clients connecting to Redis.

Getting Started after Deployment

Obtain the Credentials

Once the app is deployed, you need to obtain the credentials from the server.

To obtain credentials:

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

   • Lish Console: Log in to Cloud Manager, click the Linodes link in the left menu, and select the Compute Instance you just deployed. Click Launch LISH Console. Log in as the root user. To learn more, see Using the Lish Console.
   • SSH: Log in to your Compute 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 credentials file:

   cat /home/$USERNAME/.credentials

This returns passwords that were automatically generated when the instance was deployed. Save them. Once saved, you can safely delete the file.

Access the Redis CLI

After you log in and obtain the credentials, you can use the Redis CLI. Redis is configured to require authentication for the default user, and a valid client SSL certificate.

To access the Redis CLI, run the command:

redis-cli --tls --cacert /etc/redis/ssl/ca/ca.crt --cert /etc/redis/ssl/certs/client1.crt --key /etc/redis/ssl/keys/client1.key.pem -a $REDIS_DEFAULT_USER_PASSWORD

This opens the interactive mode where you can type commands. To learn more on the Redis CLI and available commands, see Redis CLI .

Determining How to Use Redis

There are several types of Redis configurations you can use. For example, you can configure Redis as a standalone Redis installation or a Redis cluster with a primary (master) and two replicas. As a next step, you should determine which type of deployment you require for your use case by reviewing the resources provided below.

• Learn about Redis Clusters by going through their related tutorial.
• Redis Sentinel is another deployment configuration focused on high availability. See the Redis Sentinel documentation for more details.
• Read the Redis Quickstart to learn about securing Redis and installing client libraries to use Redis with your applications.
• Refer to the Redis configuration documentation to learn about the Redis configuration file.
