Disaster Recovery 101: Architecting Auto-Failovers for MySQL and Perl Deployments on DigitalOcean

Establishing a High-Availability MySQL Cluster with Orchestrator

For critical applications, a single MySQL instance is a single point of failure. Architecting for high availability (HA) necessitates a robust failover strategy. We’ll leverage Orchestrator, a popular MySQL replication topology manager, to automate this process. Orchestrator monitors replication health and can automatically promote a replica to a primary in case of failure.

Our setup will involve a primary MySQL instance, one or more replicas, and a separate DigitalOcean Droplet dedicated to running Orchestrator. This dedicated Orchestrator instance will connect to all MySQL nodes and manage their replication relationships.

Orchestrator Installation and Configuration

First, provision a new DigitalOcean Droplet for Orchestrator. A small, inexpensive Droplet (e.g., 1 vCPU, 1GB RAM) is typically sufficient. Ensure it has network access to your MySQL Droplets.

Install Orchestrator on this new Droplet. We’ll use `wget` and `dpkg` for a Debian/Ubuntu system. The exact version might change, so consult the official Orchestrator GitHub repository for the latest stable release.

Installing Orchestrator (Debian/Ubuntu)

wget https://github.com/openark/orchestrator/releases/download/v3.2.7/orchestrator_3.2.7_linux_amd64.deb
sudo dpkg -i orchestrator_3.2.7_linux_amd64.deb

Orchestrator Configuration File

The primary configuration file is located at /etc/orchestrator/orchestrator.conf.json. We need to configure database credentials for Orchestrator to connect to MySQL and define its behavior. Ensure the user specified has sufficient privileges (e.g., `REPLICATION SLAVE`, `REPLICATION CLIENT`, `SUPER`, `PROCESS`, `SELECT`).
