Featured Guides

Configuring IP Failover using keepalived

There’s always a small possibility that your Compute instance could be powered off or become inaccessible, perhaps due to a failed internal configuration issue or server maintenance. Any websites or services hosted on that instance might also stop working when this happens. One step you can take to help mitigate this downtime is IP failover. This guide shows you how to configure IP failover on Linode.

How to Use Ansible to Deploy a Web Server, Log Server, and Database Server

Ansible is an open source, software provisioning tool that automates application and IT infrastructure deployment. It’s lightweight and agent-less, meaning there’s no client or server software to install. Ansible uses SSH and Python to accomplish its highly useful automation tasks. In this guide, you will learn how to configure an Ansible control node and a few other worker nodes, create and run an Ansible playbook that configures the worker nodes, and test your running web servers.
