Installing MariaDB MaxScale Load Balancer
FromDual Ops Center only supports MariaDB MaxScale version 6 (v2.6) and newer.
Before you start you should install the MariaDB MaxScale Load Balancer package on the machines where the MaxScale Load Balancer should reside.
MariaDB MaxScale can be downloaded from here: Download MariaDB.
Note: MariaDB MaxScale is licensed under Business Source License (BSL).
When you have downloaded the package you can install it as follows:
apt install ./maxscale-*.deb # for Debian and Ubuntu dnf localinstall ./maxscale-*.rpm # For Redhat based distributions
