Guides - Deploying Splunk through the Linode Marketplace
Quickly deploy a Compute Instance with many various software applications pre-installed and ready to use.
Splunk is a powerful log analyzer that can be used to obtain insight into your infrastructure. Splunk collects, monitors, analyzes, and visualizes data from database applications, web servers, cloud networks, and a variety of other sources.
Deploying a Marketplace App
The Linode Marketplace allows you to easily deploy software on a Compute Instance using the Cloud Manager. See Get Started with Marketplace Apps for complete steps.
Log in to the Cloud Manager and select the Marketplace link from the left navigation menu. This displays the Linode Create page with the Marketplace tab pre-selected.
Under the Select App section, select the app you would like to deploy.
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.
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.
NoteEstimated deployment time: Splunk should be fully installed within 2-5 minutes after the Compute Instance has finished provisioning.
- Supported distributions: Debian 10, Ubuntu 20.04 LTS
- Recommended minimum plan: All plan types and sizes can be used.
- Splunk Admin user (required): This will be the username you use to login the Splunk Dashboard.
- Splunk Admin Password (required): This will be the password you use to login the Splunk Dashboard.
Custom Domain (Optional)
If you wish to automatically configure a custom domain, you first need to configure your domain to use Linode’s name servers. This is typically accomplished directly through your registrar. See Use Linode’s Name Servers with Your Domain. Once that is finished, you can fill out the following fields for the Marketplace App:
- Linode API Token: If you wish to use the Linode’s DNS Manager to manage DNS records for your custom domain, create a Linode API Personal Access Token on your account with Read/Write access to Domains. If this is provided along with the subdomain and domain fields (outlined below), the installation attempts to create DNS records via the Linode API. See Get an API Access Token. If you do not provide this field, you need to manually configure your DNS records through your DNS provider and point them to the IP address of the new instance.
- Subdomain: The subdomain you wish to use, such as www for
- Domain: The domain name you wish to use, such as example.com.
- Email address for the SOA record: The start of authority (SOA) email address for this server. This is a required field if you want the installer to create DNS records.
Limited User (Optional)
You can optionally fill out the following fields to automatically create a limited user for your new Compute Instance. This is recommended for most deployments as an additional security measure. This account will be assigned to the sudo group, which provides elevated permission when running commands with the
- Limited sudo user: Enter your preferred username for the limited user.
- Password for the limited user: Enter a strong password for the new user.
- SSH public key for the limited user: If you wish to login as the limited user through public key authentication (without entering a password), enter your public key here. See Creating an SSH Key Pair and Configuring Public Key Authentication on a Server for instructions on generating a key pair.
- Disable root access over SSH: To block the root user from logging in over SSH, select Yes (recommended). You can still switch to the root user once logged in and you can also log in as root through Lish.
Getting Started after Deployment
Access your Splunk App
Open a browser and navigate to your
Linode’s IP address and port
8000, for example,
http://192.0.2.0:8000/. You will be presented a login field where you can enter the credentials you previously specified in the Splunk Username and Splunk Password fields when you deployed the app.
Now that you’ve accessed your dashboard, checkout the official Splunk documentation to learn how to further configure your instance.
NoteCurrently, Linode does not manage software and systems updates for Marketplace Apps. It is up to the user to perform routine maintenance on software deployed in this fashion.
