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 …

This is my next blog series. Im going to write about how I automated many complex tasks in MySQL with Rundeck. In my last series, I have explained RunDeck basics. You can find those articles here. In this blog Im writing about how I automated MySQL archive for multiple tables in one Rundeck job.

Challeange with Replication:

My MySQL database setup has 1 Master 4 Read Replica and the 3’rd replica is an intermediate Master for Replica 4. I don’t want to archive this data on Replica 3 and 4. Because these replicas are using for generating historical reports also some internal application.

Disable Log-Bin:

To prevent archive data on Replica 3 and 4, I decided to disable binlog on my archive session. But another challenge is, it won’t replicate to Replica 1 and 2. So my final solution is Archive the data on Master, then execute the …

Introduction :

Ansible is an open-source IT automation engine which can remove drudgery from your work life, and will also dramatically improve the scalability, consistency, and reliability of your IT environment.

Nowadays without automation to manage the Databases is very tricky. We are using Ansible as an infra automation tool to install, configure and manage DB infra at Mydbops.

For example, you have 10 Linux server’s which needs MySQL latest version 8.0 to be installed. Anyone can install MySQL using yum or apt-get. But the manual installation is a time-consuming process.

In this blog, I am going to describe the installation of MySQL 8.0 using Ansible.
