It’s not uncommon these days for us to use a high availability stack for MySQL consisting of Orchestrator, Consul, and ProxySQL. You can read more details about this stack by reading Matthias Crauwels’ blog post How To Autoscale ProxySQL In The Cloud as well as Ivan Groenwold’s post on MySQL High Availability With ProxySQL, Consul And Orchestrator. But the high-level concept is simply that Orchestrator will monitor the state of the MySQL replication topology and report changes to Consul which in turn can update ProxySQL hosts using a tool called consul-template.

Until now we’ve typically implemented the ProxySQL portion of this stack using an autoscaling group of sorts due to the high levels of CPU usage that can be associated with …

Write code, test and deploy

This is one of the common development cycles of any developer.

Most of the time testing and deployment steps do not change frequently and in order to keep the developer focus on writing code, we do the automation of testing and deployment.

This automation is called “continuous integration and deployment” OR CI/CD Pipeline.

In this tutorial, we will learn how to set up continuous integration and deployment (CI/CD) infrastructure for the Node.js project.

Prerequistics

I am going to use Jenkins as the automation tool and Github as source code management system.

Jenkins is free for use but we require public server in order to integrate the Github repository.

For the server, I will be using $5 droplet on Digitalocean. In case you wish to buy it, you …

Continuent Tungsten is one of the few all-in-one solutions for MySQL high availability. In this post I will show you how to automate the upgrade process using Ansible. I will walk you through the individual tasks and, finally, give you the complete playbook.

We will use a rolling approach, upgrading the slaves first, and finally upgrading the former master. There is no need for a master switch, as the process is transparent to the application.

I am assuming you are using the .ini based installation method. If you are still using staging host, I suggest you update your set up.

Pre tasks

The first step is ensuring the cluster is healthy, because we don’t want to start taking nodes offline unless we are sure the cluster is in good shape. One way of doing that is by using the built-in script tungsten_monitor. When we run the playbook, we only need to validate the cluster status on one node, so I am adding …
