Time to check Galera Cluster security?

There are plenty of articles on the Internet that tell you to setup a Galera Cluster by disabling an OS based firewall and also disabling SELinux. While we agree that this might be the fastest way to get your Galera Cluster setup, it is not necessarily good security hygiene, and we would prefer if you started 2022 with a bit more secure Galera Cluster!

What is SELinux? Is is Security-Enhanced Linux that allows administrators to allow who has more control over the system. It has permissive and enforcing mode, and is turned on by default in Red Hat Enterprise Linux and derivatives. It is important to remember that if you install Galera Cluster via a package that we provide, we have provided all the necessary contexts for it. You effectively do not have to disable SELinux to get started.

However, if you are using the rsync method for a …

Galera Manager updated with usability improvements for self-hosted and monitored clusters

Codership is pleased to announce a new release of Galera Manager. This brings the installer to version 1.5 and the actual Galera Manager GUI to 1.4.0.

Users will notice some usability improvements like the cluster name being added to the authorized_keys generated file, while there are benefits around gmd generating a new key for the updated installation. There is also a port checker, so if ports are used and unavailable, the user will be informed and Galera Manager will refuse to install. In addition, on Debian/Ubuntu where apt/dpkg supports interactivity, we have now ensured that all steps will remain non-interactive.

 

  We now have native support to deploy MariaDB Server 10.6 From the Galera Manager GUI standpoint, we have ensured that job monitoring and charts have better performance. One user experience enhancement for monitored or self-hosted clusters? Galera Manager now checks to ensure it has access to …

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.
