About Continuous MySQL & MariaDB Database Operations & More at Percona Live Austin This Month!

So, typically, a Percona Live (or MySQL User) Conference blog would start off with some mention of the fact that it’s great to be meeting up again in Santa Clara, California, the birthplace of the MySQL User Conference, and a continuous fixture on the yearly MySQL community agenda.

But no, not this time!

On this occasion, the Percona Live Conference blog starts off by pointing out that for the first time since its inception (as far as I can recollect), the MySQL User Conference, i.e. Percona Live Conference (in North America) doesn’t take place in Santa Clara, but rather in Austin, Texas.

Never having been to Texas before myself, I’m looking forward to that innovation, discovering the new surroundings and seeing whether that changes anything or not to the familiar “feel” of a Percona Live / MySQL User Conference.

By the way, there’s still time to …

MySQL Server Deployment with Docker – Basic Installation Instructions for Both the Community and Enterprise Versions

An easy way to setup one or multiple MySQL server deployments on a single server is to use Docker – a computer program that performs operating-system-level virtualization. Docker is simple-to-use and allows you to run multiple containers at once.

A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings. (Source: https://www.docker.com/resources/what-container)

In other words, think of a container as a virtual machine without the graphical user interface (GUI). There are third-party GUI’s available, but for this post, I am going to use a …

On the Database Market. Interview with Merv Adrian

“Anyone who expects to have some of their work in the cloud (e.g. just about everyone) will want to consider the offerings of the cloud platform provider in any shortlist they put together for new projects. These vendors have the resources to challenge anyone already in the market.”– Merv Adrian.

I have interviewed Merv Adrian, Research VP, Data & Analytics at Gartner. We talked about the the database market, the Cloud and the 2018 Gartner Magic Quadrant for Operational Database Management Systems.

RVZ

Q1. Looking Back at 2018, how has the database market changed?

Merv Adrian: At a high level, much is similar to the prior year. The DBMS market returned to double digit growth in 2017 (12.7% year over year in Gartner’s estimate) to $38.8 …

mysql_clear_password & authentication_ldap_simple password encryption

Preparing for my talk at the HK Open Source Conference I wanted to confirm some of the things I had read about these plugins, mostly from Matthias Crauwels excellent article on the subject.

My lab environment consists of Windows 2016 Domain controller and client machines, with MySQL 8 running on Oracle Linux 7.

First I configure the database to use the server-side plugin, configure the plugin to point to the domain controller, and create a database user associated via the plugin with my Windows account.

mysql> INSTALL PLUGIN authentication_ldap_simple SONAME 'authentication_ldap_simple.so';
Query OK, 0 rows affected (0.05 sec)

mysql> SET GLOBAL authentication_ldap_simple_server_host='win-dc.windows.domain'; …

Replicating data between two MySQL Group Replication sets using “regular” asynchronous replication with Global Transaction Identifiers (GTID’s)

MySQL introduced Group Replication (GR) in version 5.7, and GR is part of the InnoDB Cluster high-availability solution. InnoDB Cluster consists of Group Replication, MySQL Shell and MySQL Router.

I am not going to explain InnoDB Cluster or Group Replication in this post. So, if you aren’t familiar with either one, I have some previous posts in which I have explained how to work with both. See:

MySQL 8.0 Group Replication – …

MySQL 8.0 Group Replication – Three-server installation

MySQL InnoDB Cluster was introduced in MySQL version 5.7. MySQL InnoDB Cluster consists of three parts – Group Replication, MySQL Shell and MySQL Router. MySQL InnoDB Cluster provides a complete high availability solution for MySQL. I am not going to go into the details of InnoDB Cluster and how it works, as there are enough manual pages and blogs to cover these topics.

MySQL InnoDB Cluster manual
Blog sites: mysqlhighavailability.com and mysqlserverteam.com.

Instead, I will be showing you how to install Group Replication on three new installations of mysql 8.0 manually, without using the MySQL Shell.

These instructions should enable you to setup Group Replication in less than an hour. I …

Testing MySQL NDB Cluster with dbdeployer

Tweet

A great way to install MySQL when you need to do quick tests is to use a sandbox tool. This allows you to perform all the installation steps with a single command making the whole process very simple, and it allows for automation of the test. Giuseppe Maxia (also known as the Data Charmer, @datacharmer on Twitter) has for many years maintained sandbox tools for MySQL, first with MySQL Sandbox and now with dbdeployer.

One of the most recent features of dbdeployer is the support for MySQL NDB Cluster. In this blog, I will take …
