Galera Manager November 2023 Release now includes deployment and monitoring for Percona XtraDB Cluster (PXC) 8.0

Codership is pleased to announce a new release of Galera Manager. This brings the installer to version 1.11.0 (you can check this by typing: ./gm-installer version which will report gm-installer version 1.11.0 (linux/amd64)) and the actual Galera Manager GUI to 1.8.0. Users will notice many usability improvements, and multiple fixes for issues filed at the galera-manager-support issue tracker.

The biggest items in this release include operating system (OS) and database engine support. The wide range includes MariaDB Server 10.9, 10.10 and 10.11 LTS, plus we are also excited to announce that you can now deploy a Percona XtraDB Cluster (PXC) 8.0 cluster entirely via Galera Manager, via AWS, DigitalOcean or on servers you provide yourself!

So now the support matrix for operating systems are:

  • Debian 11
  • Red Hat Enterprise Linux 8
  • Ubuntu 20.04
  • Ubuntu 22.04
  • CentOS 7 (deprecated)
  • Debian 10 (deprecated)
  • Ubuntu 18.04 (deprecated)

And the matrix for database engines are:

  • MariaDB 10.3
  • MariaDB 10.4
  • MariaDB 10.5
  • MariaDB 10.6 LTS
  • MariaDB 10.7
  • MariaDB 10.9
  • MariaDB 10.10
  • MariaDB 10.11 LTS
  • MySQL 5.7
  • MySQL 8.0
  • Percona XtraDB Cluster (PXC) 8.0

Deprecated does not mean removed, it just means that it is likely to be removed in a future release. The reason we deprecate engines and operating systems is for the sole reason that they are not necessarily supported upstream any longer, but may still have customers and users who utilise it. More importantly, the next releases should also start supporting upgrades which could be quite significant.

One change that is important is that we have an agent installed on all managed nodes now, called gma. It runs to detect connectivity, but in future releases it will be run to execute commands in an unattended fashion, which we believe will be more reliable than the current SSH method, when the connection breaks. You can find this in /usr/local/bin/gma.

From a usability standpoint, it is nice to see a few improvements, with a nice new Properties tab, and when you install it, a much nicer look at logs.

A personal favourite is that the SSH client now does not launch a new window, but is within the same browser window as a popup.
