MySQL install ‘n’ config one-liners

Back again, now with MySQL installs. And this means using the MySQL repository this time around.

I’ve been installing and configuring InnoDB Clusters and ClusterSets and thinking about the Ansible and Terraform users amongst us, maybe one-liners might help someone out there.

So, what about if I share how to install the MySQL repo, install the MySQL instance, create an InnoDB Cluster, add a MySQL Router, create a ClusterSet, make sure the Router is ClusterSet-aware, and then test it out. And all via one-liners.

First up, obrigado Miguel for https://github.com/miguelaraujo/ClusterSet-Demo.

To simplify the command execution sequence, these sections aim to help summarize the technical commands required to create the whole platform. And on a default path & port configuration, to ease operational deployments for all those 000’s of …

ClusterSet, Router Integration & Operational Details uncovered, part2 of a Series

In the first part of this short series, we went through the build of a full Clusterset architecture, which included 2 full clusters (3 members each) and an additional cluster with one member, which can serve different purposes. With the MySQL ClusterSet, there are new capabilities with the router instances. These features enable valuable options for users of… Read More »

Building out the MySQL InnoDB ClusterSet for High Availability & Disaster Recovery in a fully supported Platform

InnoDB Cluster has been around for what feels like a long time. It is the core platform for MySQL High Availability. InnoDB Cluster NOW extends that core feature into a platform that also enables DR support where multiple Disaster Recovery Regions are capable.

Deploy Apache Superset with MySQL Database Service on OCI

We already saw how easy it’s to deploy solutions on OCI using Terraform and Resource Manager’s Stack. I’ve published several resources available on this page.

Today we will see how easy it’s to deploy Apache Superset on OCI using MySQL Data Service.

Apache Superset is an open source BI, Reporting, Charting tool that competes with Tableau, Looker, etc.  For a list of companies that have deployed Superset, see:  https://github.com/apache/superset/blob/master/RESOURCES/INTHEWILD.md.

Superset is loaded with options that make it easy for users of all skill sets to explore and visualize their data, from simple line charts to highly detailed geospatial charts.

Point-in-Time Recovery in OCI MDS with Object Storage – part 2

In part 1 of the series about Point-in-Time Recovery in OCI MDS, we saw how to stream the binary log to Object Storage.

In this blog post, we will see how we can restore the data up to certain point.

The high level process is simple:

  1. we need to restore the last backup just before the point we want to return to
  2. find the last GTID that was executed in that backup (not 100% mandatory but can accelerate the process)
  3. choose what is the objective:
    1. just skip one transaction (following transaction could depend on it)
    2. recover up to that transaction and skip all the following ones
  4. replay the binary logs taking in consideration the chosen option of point 3

The scenario …

Point-in-Time Recovery in OCI MDS with Object Storage – part 1

To setup point-in-time recovery for MDS using Object Storage, these are the prerequisites:

  • a MDS instance running
  • a backup plan (default)
  • a compute instance
  • an Object Storage Bucket

In this article, I won’t focus on how to create a MDS instance, a compute instance, enable backups and Object Storage Bucket, this is easy and there is already a lot of literature about them (you can also check several of my previous articles).

This is part 1 of the Point-in-Time Recovery in OCI MDS series. It’s only about streaming the binary logs to Object Store. In part 2, we will see how to use them and perform PITR.

Saving the binary logs

In fact most of the work will be to setup the compute instance to store the binary logs coming from MDS (one single compute instance could stream those binlogs from multiple MDS source).

On the compute instance we need …

Setup Disaster Recovery for OCI MySQL Database Service

When you create a MySQL Database Service instance in OCI, you have the choice between 3 types:

If you have minutes as RTO (Recovery Time Objective) in case of a failure, you must choose a High Availability instance that will deploy a Group Replication Cluster over 3 Availability Domains or 3 Fault Domains. See Business Continuity in OCI Documentation.

These are the two options:

Natural disasters happen – fires, floods, hurricanes, typhoon, earthquakes, lightning, explosion, volcanos, prolonged shortage of energy supplies or even acts of governments happen which could impede things. Having a DR copy …

MySQL Database Service: administrator user

On MySQL Database Service (aka MDS) on Oracle Cloud Infrastructure (aka OCI), when you create a new instance, you also need to set the credentials for the administrator:

Let’s focus on that account…

Please don’t forget the password, it cannot be recovered !!

First of all that account’s username has some limitations. Indeed, some names are reserved as it’s mentioned in the manual. So you could not use the following usernames:

  • administrator
  • ociadmin
  • ocirpl
  • mysql.sys
  • mysql.session
  • mysql.infoschema

This list can evolve, you can get the list directly from the MySQL DB System creation’s screen:

In fact, those accounts are already existing in the MySQL DB …
