options:
dataset-size:
default: '80%'
description: 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. Any more specific settings will override these defaults though. This currently sets innodb_buffer_pool_size or key_cache_size depending on the setting in preferred-storage-engine. If query-cache-type is set to 'ON' or 'DEMAND' 20% of this is given to query-cache-size. 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 and (if enabled) query cache.
type: string
preferred-storage-engine:
default: InnoDB
type: string
description: Tune the server for usage of this storage engine. Other possible value is MyISAM. Comma separated will cause settings to split resources evenly among given engines.
tuning-level:
default: safest
type: string
description: Valid values are 'safest', 'fast', and 'unsafe'. If set to safest, all settings are tuned to have maximum safety at the cost of performance. Fast will turn off most controls, but may lose data on crashes. unsafe will turn off all protections.
flavor:
default: distro
type: string
description: Possible values are 'distro' or 'percona'
query-cache-type:
default: "OFF"
type: string
description: Query cache is usually a good idea, but can hurt concurrency. Valid values are "OFF", "ON", or "DEMAND". http://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html#sysvar_query_cache_type
query-cache-size:
default: -1
type: int
description: Override the computed version from dataset-size. Still works if query-cache-type is "OFF" since sessions can override the cache type setting on their own.
max-connections:
default: -1
type: int
description: Maximum connections to allow. -1 means use the server's compiled in default.
binlog-format:
default: 'MIXED'
type: string
description: If binlogging is enabled, this is the format that will be used. Ignored when tuning-level == fast.
vip:
type: string
default: ''
description: "Virtual IP to use to front mysql in ha configuration"
vip_iface:
type: string
default: eth0
description: "Network Interface where to place the Virtual IP"
vip_cidr:
type: int
default: 24
description: "Netmask that will be used for the Virtual IP"
ha-bindiface:
type: string
default: eth0
description: |
Default network interface on which HA cluster will bind to communication
with the other members of the HA Cluster.
ha-mcastport:
type: int
default: 5411
description: |
Default multicast port number that will be used to communicate between
HA Cluster nodes.
block-size:
type: int
default: 5
description: |
Default block storage size to create when setting up MySQL block storage.
This value should be specified in GB (e.g. 100 not 100GB).
rbd-name:
type: string
default: mysql1
description: |
The name that will be used to create the Ceph's RBD image with. If the
image name exists in Ceph, it will be re-used and the data will be
overwritten.
ceph-osd-replication-count:
default: 2
type: int
description: |
This value dictates the number of replicas ceph must make of any
object it stores within the mysql rbd pool. Of course, this only
applies if using Ceph as a backend store. Note that once the mysql
rbd pool has been created, changing this value will not have any
effect (although it can be changed in ceph by manually configuring
your ceph cluster).
