Configuration file
(optional, string, no default)
datadir
Directory containing databases
(optional, string, no default)
user
User running MySQL daemon
(optional, string, no default)
group
Group running MySQL daemon (for logfile and directory permissions)

pid
The pidfile to be used for mysqld.
(optional, string, no default)
socket
The socket to be used for mysqld.
(optional, string, no default)
enable_creation
If the MySQL database does not exist, it will be created
(optional, boolean, default false)
additional_parameters
Additional parameters which are passed to the mysqld on startup. (e.g. --skip-external-locking or
--skip-grant-tables)
(optional, string, no default)
wsrep_cluster_address
The galera cluster address. This takes the form of: gcomm://node,node,node
Only nodes present in this node list will be allowed to start a galera instance. The galera node
names listed in this address are expected to match valid pacemaker node names. If both names need to
differ, you must provide a mapping in option cluster_host_map.
(required, string, no default)
cluster_host_map
A mapping of pacemaker node names to galera node names.
To be used when both pacemaker and galera names need to differ, (e.g. when galera names map to IP
from a specific network interface) This takes the form of:
pcmk1:node.1.galera;pcmk2:node.2.galera;pcmk3:node.3.galera
where the galera resource started on node pcmk1 would be named node.1.galera in the
wsrep_cluster_address
(optional, string, no default)
check_user
Cluster check user.
(optional, string, no default)
check_passwd
Cluster check user password. Empty passwords are ignored unless the parameter
"check_passwd_use_empty" is set to 1.
(optional, string, no default)
check_passwd_use_empty
Use an empty "check_passwd" password. If this parameter is set to 1, "check_passwd" will be ignored
and an empty password is used when calling the "mysql" client binary.
(optional, boolean, default 0)
two_node_mode
If running in a 2-node pacemaker cluster, rely on pacemaker quorum to allow automatic recovery even
when the other node is unreachable. Use it with caution! (and fencing)
(optional, boolean, default false)
