Since Drupal VM is built in a modular fashion, and the upstream Ansible Role that installs and configures MySQL is built in a way that works with any MySQL-compatible replacement, you can easily swap out MySQL for MariaDB.
The simplest way is to add the following lines after the # MySQL Configuration.
line in config.yml
:
mysql_packages:
- mariadb-client
- mariadb-server
- python-mysqldb
This set of packages works out of the box with the default Ubuntu 14.04 installation that comes with Drupal VM.
Alternatively, if you want to use RedHat 7 or CentOS 7 instead of Ubuntu, you can set the following variables to install and configure MariaDB instead of MySQL:
mysql_packages:
- mariadb
- mariadb-server
- mariadb-libs
- MySQL-python
- perl-DBD-MySQL
mysql_daemon: mariadb
mysql_socket: /var/lib/mysql/mysql.sock
mysql_log_error: /var/log/mariadb/mariadb.log
mysql_syslog_tag: mariadb
mysql_pid_file: /var/run/mariadb/mariadb.pid
