There are several ways to get ClusterControl installed on your database infrastructure, as described in the ClusterControl Quick Start Guide. One simple way is to use an installation script, install-cc.sh. This script automates the whole process, and is executed on the host where you want to install ClusterControl. By default, it assumes the host has internet connectivity during the installation process.

For users who are not able to have their ClusterControl hosts connect to the Internet during the installation, we have some good news! The installer script now supports offline installations.

Requirements

Prior to the offline …

We just wanted to make it official: Severalnines ClusterControl now supports MariaDB 10!

As most of you know will know by now, MariaDB 10 is the newest and most advanced version of the popular MariaDB relational database system. Whilst remaining application-compatible with the MySQL database, it adds many new capabilities to address the most challenging web and enterprise application use cases. Cluster deployments would be based on MariaDB Galera Cluster 10, which is a complete merge of MariaDB 10.0.12 and Galera Cluster. 

ClusterControl for MariaDB Clusters

ClusterControl gives you the power to deploy, manage, monitor and scale entire MariaDB Galera clusters efficiently and …

ClusterControl uses the Apache HTTP Server to serve its web interface, but it is also possible to use nginx. nginx + PHP fastcgi is well-known for its capabilities to run on a small memory footprint compared to standard Apache + PHP DSO.

In this post, we will show you how to run ClusterControl on nginx web server by swapping out the default Apache web server installed during the initial deployment. This blog post does not mean that we officially support nginx, it just an alternative way that a portion of our users have been interested in. For instance, Phil Bayfield wrote a blog on the same topic a while back.

Apache Configuration

Before we jump into nginx configurations, let’s look at how the …

ClusterControl 1.2.6 introduces integration with Active Directory and LDAP authentication. This allows users to log into ClusterControl by using their corporate credentials instead of a separate password. LDAP groups can be mapped onto ClusterControl user groups to apply roles to the entire group, so it is very convenient for larger organizations who have a centralized LDAP-compliant authentication system. This blog shows you how to configure LDAP authentication in ClusterControl, and allow users to use their Active Directory or LDAP username and password to log in to ClusterControl. 

LDAP authentication can be configured from ClusterControl, in the Admin dashboard (ClusterControl > Admin > LDAP Settings). If you are running ClusterControl v1.2.5 or older, please …

In the wake of recent concerns and debates raised around the Heartbleed bug, we wanted to update Severalnines ClusterControl users on any impact this bug might have on ClusterControl & associated databases and/or applications.

Background

If your ClusterControl's web application has been accessible on the internet, then most likely you have also been exposed to the Heartbleed OpenSSL security bug, see: http://heartbleed.com for more details. 

By default, our database deployment script enables SSL encryption for the Apache web server on the Controller host with a generated private SSL key and a self-signed certificate. SSL encryption is used between the UI and the Controller REST API if you have clusters added with HTTPS, which we do by default. The content that is encrypted …

In my last blog post I explained how to use Percona ClusterControl to create a new Percona XtraDB Cluster from scratch. That’s a good option when you want to create a testing environment in just some mouse clicks. In this case I’m going to show you how to add your existing cluster to Percona ClusterControl so you can manage and monitor it on the web interface.

The environment will be pretty similar, we will have UI, CMON and 3 XtraDB Cluster nodes. The cluster should be already running and Percona ClusterControl also installed.

Adding an existing Cluster

The ClusterControl web interface is empty, there are no clusters on it. To add an existing one …
