Webinar: Galera Manager is now GA with ability to launch clusters on premise and in the AWS cloud

This is a new era in deploying, managing and monitoring your Galera Cluster for MySQL, with the recently released Galera Manager, now Generally Available (GA). Galera Manager is a web-based graphical user interface (GUI) tool that allows you to fully manage clusters in Amazon Web Services, you can also deploy clusters on user provided hosts (on premise or in the cloud) and you can also fully monitor your existing clusters.

In this Webinar, we will cover:

  • Deploying a fully managed cluster in AWS
  • Deploying a cluster on user-provided hosts
  • Monitoring an existing cluster
  • How we have chosen to use CLONE SST for MySQL 8 deployments
  • How you can successfully deploy all the various servers that we support
  • Utilising the over 600 monitoring metrics to effectively manage your Galera Cluster

Galera Manager deploying on AWS with Red Hat Enterprise Linux 8 and MySQL 8

Since we just released Galera Manager, it seemed like a good idea to do a deployment on Amazon Web Services (AWS) using Red Hat Enterprise Linux 8 and MySQL 8.

We start by launching an EC2 instance and choosing Red Hat Enterprise Linux 8 (HVM) and most importantly, we only choose the 64-bit (x86) architecture as we do not support ARM just yet. We choose a t2.micro instance for Galera Manager since this is just a test instance, but it is well worth knowing that 10GB which is the default EBS size may be a little small if you plan on using this for sometime.

Galera Streaming Replication Feature Deep Dive Video and Blog

Just last week we had a Galera Cluster for MySQL streaming replication feature deep dive webinar, by the person that implemented it – Seppo Jaakola. In fact, if you haven’t already read the entire story, we encourage you to read: Galera Streaming Replication: Too Big A Bite Can Choke Your Cluster. We also have the 60 minute video recording for reference.

A huge number of Galera Cluster users have always complained about having issues with large transactions (where writes hang but reads are OK), and we are certain that the correct usage of streaming replication is what will ease that burden. What constitutes a large transaction? Typically when you make big number of …

Installing Galera 4 with MySQL 8 on Ubuntu 20.04

A question has cropped up recently: how does one install Galera Cluster 4 with MySQL 8 on Ubuntu 20.04 LTS (Focal Fossa)? This quick guide will get you started.

Install 3 Galera Cluster nodes with the base OS being Ubuntu 20.04. Remember to run apt update and apt upgrade.

Effective Monitoring of your Galera Cluster for MySQL with Galera Manager

While we have documented how you might consider Monitoring a Cluster with Galera Manager, we’d also like to take you through a bit more of what is available, before our webinar this week. Please signup for a live demo from install to deployment and management.

You might be used to SHOW GLOBAL STATUS LIKE 'wsrep_%'; from the command line, but why not take a look at all of this on a graph, over time, within the GUI of the Galera Manager? What happens when you feel a node is getting overwhelmed? You tend to check wsrep_flow_control_paused, which returns the percentage of time the node was paused because of Flow Control (normally you do this after a FLUSH STATUS however now you …

Webinar: The New Galera Manager Deploys Galera Cluster for MySQL on Amazon Web Services

There is NEW ERA for Galera Cluster monitoring and management and as we just recently released Galera Manager 1.0 into the wild for everyone to deploy their Galera Clusters within an Amazon Web Services (AWS) Elastic Compute Cloud (EC2) environment to achieve MySQL High Availability, Multi-Master MySQL, active-active clustering out of the box on Amazon and Disaster Recovery, all from the comfort of a web-based graphical user interface (GUI).

The Galera Manager is the new graphical user interface (GUI) tool for provisioning Galera Clusters on Amazon Web Services (AWS) Elastic Compute Cloud (EC2). It allows an administrator to easily create and add nodes, without manually having to configure each node.
