Disaster Recovery 101: Architecting Auto-Failovers for MySQL and Python Deployments on Linode

Establishing a MySQL High Availability Cluster with Orchestrator

For robust disaster recovery and automated failover, a primary-replica MySQL setup is insufficient. We need a cluster that can detect failures and promote a replica without manual intervention. Orchestrator is a powerful, open-source tool designed for MySQL topology management and high availability. It operates by discovering your MySQL topology, understanding replication relationships, and providing APIs and a web UI to manage and automate failovers.

Our architecture will involve at least three MySQL instances: one primary and two replicas. Orchestrator will run on a separate node (or nodes for its own HA) and monitor these MySQL instances. In the event of a primary failure, Orchestrator will automatically reconfigure the remaining replicas to point to a new primary.

Orchestrator Installation and Configuration

We’ll install Orchestrator on a dedicated Linode instance. The installation process typically involves downloading the binary or using a package manager if available. For this example, we’ll assume manual binary installation.

First, download the latest Orchestrator binary. You can find releases on the official GitHub repository.

wget https://github.com/openark/orchestrator/releases/download/v3.2.7/orchestrator-3.2.7-linux-amd64.tar.gz
tar xvfz orchestrator-3.2.7-linux-amd64.tar.gz
sudo mv orchestrator-3.2.7-linux-amd64 /usr/local/bin/orchestrator
sudo chmod +x /usr/local/bin/orchestrator

Next, we need to configure Orchestrator. A configuration file (e.g., orchestrator.conf.json) is essential. This file specifies database credentials for Orchestrator to connect to MySQL, discovery settings, and failover policies.
