Galera Manager updated to handle DigitalOcean updated API tokens

A few weeks ago, we did a Galera Cluster webinar on Managed Galera Clusters on DigitalOcean.

Some of you may notice that the current version of Galera Manager is 1.6.4, and one of the major fixes we have in there is to support the new API token format of DigitalOcean. DigitalOcean has documented this here: Updated API Tokens new management features: in partnership with GitHub –Secret Scanning, Prefixes, and more! and as a consequence we needed to update to accept new API tokens, or it would fail in deployment. If you’re wondering how to create a …

Minor version upgrade of a Galera Cluster for MySQL

Recently we got a question about how one can perform a minor version upgrade of a Galera Cluster, and today we just want to say that it is reasonably straightforward. While upgrades are a feature of Galera Manager that we are most excited to see come soon, today, doing it manually on the command line is quite simple! In this post, we will go through upgrading a 9-node geographically spread cluster, from MySQL 8.0.23 to 8.0.26. We also have extensive documentation: Upgrading Galera Cluster.

We have 3 nodes each in Singapore, London and San Francisco, making the cluster comprise of a total of 9 nodes, as we can confirm by executing: show status like 'wsrep_cluster_size';.

Since we installed all this via the RPM package manager on CentOS 7 by adding the YUM repository to the …

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 …
