Become a ClusterControl DBA: Adding Existing Databases and clusters (updated)

In our previous blog post we covered the deployment of four types of clustering/replication: MySQL Galera, MySQL master-slave replication, PostgreSQL replication set and MongoDB replication set.

This post is the first in the “Become a PostgreSQL DBA” blog series and will cover provisioning and deployment.

Become a ClusterControl DBA: Making your DB components HA via Load Balancers

There are various ways to retain high availability with databases. You can use Virtual IPs (VRRP) to manage host availability, you can use resource managers like Zookeeper and Etcd to (re)configure your applications or use load balancers/proxies to distribute the workload over all available hosts.

How to Install ClusterControl on Servers without Internet Access

There are several ways to get ClusterControl installed on your database infrastructure, as described in the ClusterControl Quick Start Guide.

By default, it assumes the host has internet connectivity during the installation process.

How to Deploy Percona XtraDB Cluster without Internet Connection

If you need to deploy a database cluster behind your corporate firewall, on servers with no internet access, then this blog is for you. Most of the installation tutorials out there require servers to have an internet connection, and that would not work very well with companies under strict policies and compliance guidelines.
