The Best Way to Host MySQL on Azure Cloud

Are you looking to get started with the world’s most popular open-source database, and wondering how you should setup your MySQL hosting? So many default to Amazon RDS, when MySQL performs exceptionally well on Azure Cloud. While Microsoft Azure does offer a managed solution, Azure Database, the solution has some major limitations you should know about before migrating your MySQL deployments.

InnoDB Cluster: Recovering an instance with MySQL Enterprise Backup.

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 …

Backup your data

Before heading into the gory details, let’s first take a look at the best practices at a high level:

  • Make sure you can restore your backups:
    • Document and script the restore procedures. Do you know the steps required to restore a full backup – or a single table?
    • Keep copies of the backups off-site. Do you have a copy of your backup if the data center becomes unavailable for example due to a fire?
    • Validate your …
