Fastest in-memory database.

Redis is the go-to database for web applications and other projects that require data processing speed over anything else. Redis stands out from relational databases by using key-values to store data, resulting in faster response times when calling data. Redis is ideal for projects with a clearly-defined data structure and when speed is more important than scalability. But that doesn’t mean that Redis is limited in its read and write operations. 

Redis is the Swiss Army knife of databases by combining high performance, high-level data structures, and ease of use. Simplify Redis database deployments with Linode’s Redis Marketplace app.

Deploying the Redis Marketplace App

  1. Log in to the Cloud Manager and select the Marketplace link from the left navigation menu. This displays the Linode Compute Create page with the Marketplace tab pre-selected.
  2. Under the Select App section, select the app you would like to deploy.
  3. Fill out all required Options for the selected app as well as any desired Advanced Options (which are optional). See the Configuration Options section for details.
  4. Complete the rest of the form as discussed within the Getting Started > Create a Linode.
  5. Click the Create Linode button. Once the Linode has provisioned and has fully powered on, wait for the software installation to complete. If the Linode is powered off or restarted before this time, the software installation will likely fail. To determine if the installation has completed, open the Linode’s Lish console and wait for the system login prompt to appear.
  6. Follow the instructions within the Getting Started After Deployment section.

Software installation should complete within 2-5 minutes after the Linode has finished provisioning.

Redis Options

Here are the additional options available for this Marketplace App:

Admin Email for the serverThis email is require to generate the SSL certificates. Required
Your Linode API TokenYour Linode API Token is needed to create DNS records. If this is provided along with the subdomain and domain fields, the installation attempts to create DNS records via the Linode API. If you don’t have a token, but you want the installation to create DNS records, you must create one before continuing.
SubdomainThe subdomain you wish the installer to create a DNS record for during setup. The suggestion given is www. The subdomain should only be provided if you also provide a domain and API Token
DomainThe domain name where you wish to host your Wazuh instance. The installer creates a DNS record for this domain during setup if you provide this field along with your API Token.
The limited sudo user to be created for the LinodeThis is the limited user account to be created for the Linode. This account has sudo user privileges.
The password for the limited sudo userSet a password for the limited sudo user. The password must meet the complexity strength validation requirements for a strong password. This password can be used to perform any action on your server, similar to root, so make it long, complex, and unique.
The SSH Public Key that will be used to access the LinodeIf you wish to access SSH via Public Key (recommended) rather than by password, enter the public key here.
Disable root access over SSH?Select Yes to block the root account from logging into the server via SSH. Select No to allow the root account to login via SSH.

Configuration Options

For advice on filling out the remaining options on the Create a Linode form, see Creating a Compute Instance. Some options may be limited or have recommended values based on this Marketplace App:

  • Supported distributions: Debian 11, Ubuntu 20.04 LTS
  • Recommended 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.

Getting Started After Deployment

Access the Redis CLI

  1. Log in to your new Compute Instance through Lish or SSH using either the root user or limited user and the associated password you entered when creating the instance.
  2. To use the redis-cli, run either of the commands below:
    • redis-cli: This opens the interactive mode where you can type in whichever commands you wish.
    • redis-cli [argument], where [argument] is the argument or command you wish to run. For instance, running redis-cli ping should result in the output of PONG if redis is configured properly.

For more information about the redis-cli and the commands you have available, see redis-cli, the Redis command line interface.

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.

The Redis Marketplace App was built by Linode. For support regarding app deployment, contact Linode Support via the information listed in the sidebar. For support regarding the tool or software itself, visit Redis Community.
