# maxscale

Install MariaDB MaxScale on a server.

Tasks

Tasks are separated in several files, included in tasks/main.yml:

• packages_stretch.yml: repository and packages installation
• mysql_add_user.yml: An utility task to add the two users used by MaxScale on a MySQL cluster
• config_stretch.yml: configuration

Variables

• maxscale_version: the version of MariaDB MaxScale to install
• maxscale_mysql_user: the mysql user MaxScale use to get the list of databases/users/tables/… on the MySQL cluster.
• maxscale_mysql_password: the plaintext password MaxScale use to connect on the cluster with maxscale_mysql_user.
• encrypted_maxscale_mysql_password: the same variable as above but encrypted by maxpasswd on the MaxScale server (currently the plaintext version is still needed if mysql_add_user.yml is used).
• maxscale_monitor_user: the mysql user MaxScale use to check the status of the MySQL servers.
• maxscale_monitor_password: the plaintext password of maxscale_monitor_user.
• encrypted_maxscale_mysql_password: the same variable as above but encrypted by maxpasswd on the MaxScale server (currently the plaintext version is still needed if mysql_add_user.yml is used).
• maxscale_mysql_master: (optional) the master server ansible will create maxscale_mysql_user and maxscale_monitor_user on (keeping it Null cause mysql_add_user.yml to not be included).
• maxscale_mysql_servers: list of the MySQL servers of the cluster MaxScale should monitor and connect to.
• maxscale_services: list of services MaxScale will define and the ports they should listen to.
