[Learn about configurations >](https://juju.is/docs/juju/configuration#heading--application-configuration)

* access-network | string

  The IP address and netmask of the 'access' network (e.g., 192.168.0.0/24)
  .
  This network will be used for access to database services.
* dataset-size | string

  Default: 80%

  How much data do you want to keep in memory in the DB. This will be used to tune settings in the database server appropriately. Suffix this value with 'K','M','G', or 'T' to get the relevant kilo/mega/etc. bytes. If suffixed with %, one will get that percentage of RAM devoted to dataset.
* ha-bindiface | string

  Default: eth0

  Default network interface on which HA cluster will bind to communication with the other members of the HA Cluster.
* ha-mcastport | int

  Default: 5490

  Default multicast port number that will be used to communicate between HA Cluster nodes.
* innodb-file-per-table | boolean

  Default: True

  Turns on innodb\_file\_per\_table option, which will make MySQL put each
  InnoDB table into separate .idb file. Existing InnoDB tables will remain
  in ibdata1 file - full dump/import is needed to get rid of large
  ibdata1 file
* max-connections | int

  Default: -1

  Maximum connections to allow. -1 means use the server's compiled in default.
* prefer-ipv6 | boolean

  If True enables IPv6 support. The charm will expect network interfaces
  to be configured with an IPv6 address. If set to False (default) IPv4
  is expected.
  .
  NOTE: these charms do not currently support IPv6 privacy extension. In
  order for this charm to function correctly, the privacy extension must be
  disabled and a non-temporary address must be configured/available on
  your network interface.
* root-password | string

  Root password for MySQL access; must be configured pre-deployment for Active-Active clusters.
* source | string

  Additional package install location
* source-galera | string

  Package install location for Galera Cluster (defaults to distro for >= 14.04)
* source-galera-key | string

  Default: BC19DDBA

  key for source-galera repository
* sst-password | string

  Re-sync account password for new cluster nodes; must be configured pre-deployment for Active-Active clusters.
* vip | string

  Virtual IP to use to front Galera Cluster in active/active HA configuration
* vip\_cidr | int

  Default: 24

  Netmask that will be used for the Virtual IP
* vip\_iface | string

  Default: eth0

  Network interface on which to place the Virtual IP
