Puppet is an open source systems management tool for centralizing and automating configuration management. Automation tools help to minimize manual and repetitive tasks, and can save a great deal of time.

Puppet works by default in a server/agent model. Agents fetch their “catalog” (final desired state) from the master and apply it locally. Then they report back to the server. The catalog is computed depending on “facts” the machine sends to the server, user input (parameters) and modules (source code).

In this blog, we’ll show you how to deploy and manage MySQL/MariaDB instances via Puppet. There are a number of technologies around MySQL/MariaDB such as replication (master-slave, Galera or group replication for MySQL), SQL-aware load balancers like ProxySQL and MariaDB MaxScale, backup and recovery tools and many more which we will cover in this blog series. There are also many modules available in the Puppet Forge …

Ok, so if you’re reading this, then I can guess you’ve got a MySQL InnoDB Cluster in an awkard shape, i.e. you need to restore a backup and add the instance back into the cluster, so we have all our instances again.

As it might be logical to think “ah, but I’ve only lost 1 instance, a read-only instance, so all I have to do is backup & restore the other read-only instance and I’m home free. Well I want to make it a little harder. So in this scenario, assume that we’ve lost both the READ-ONLY instances, so I need to backup my primary READ-WRITE instance.

I’ve got a 8.0.16 instance, on Oracle Linux 7.4. We’ll be looking at 2 hosts, ic1 & ic3.

We’ll be using the MySQL Enterprise Edition Server, that bundles MySQL Enterprise Backup with the rpm’s so we don’t need to install anything else.

I’ll assume you’ve got access to Oracle …

It was all aboard the Lone Star river boat for the 100 delegates who joined our Community Dinner. Loading took quite some time, Tom Basil attended to the guest list, and then the necessary signatures for those aboard. I’d woken at 6am to a less than favorable forecast, but the weather was kind to us, with blue sky and a gentle breeze.

My colleague and local Austin resident Rick Vasquez had on Tuesday treated me to my first visit to a US liquor store, Specs. This store was bigger than the largest store in my hometown but sold only alcohol-related products and drink-friendly snacks. An experience in itself! We stuck to the brief of Texas-only brew for our guests.

As people boarded they received their swag – PlanetScale and Percona branded steel enamel mugs – and bar and dinner queues formed. The lines moved relatively quickly for the fajita and tex mex themed buffet. …
