MariaDB (MySQL) Ansible role for Debian

Install and configure MariaDB (Galera Cluster). Manage replication (master/slave). Create users and databases.

OS	Origin	MariaDB versions
Debian Stretch	Debian	10.1
Debian Stretch	Upstream	10.1 / 10.2 / 10.3 / 10.4
Debian Buster	Debian	10.3
Debian Buster	Upstream	10.3 / 10.4

Notes

• Galera Cluster is experimental
• Due to Vagrant + Docker limitation (private network), replication/galera can't be checked with Travis
• If you need to test this role with Vagrant, you must install hostmanager plugin: vagrant plugin install vagrant-hostmanager
• Percona Xtrabackup is not available in upstream repository. This feature is disabled in the role.

Requirements

Ansible 2.5+

Role Variables

• mariadb_use_galera: set true to configure and install Galera Cluster

Configuration

    priv: ipsum.*:ALL
    host_all: yes
