56       socket
57           The socket to be used for mysqld.

59           (optional, string, no default)
60
61       enable_creation

65
66       additional_parameters
67           Additional parameters which are passed to the mysqld on startup.

69
70           (optional, string, no default)
71
72       wsrep_cluster_address
73           The galera cluster address. This takes the form of:
74           gcomm://node,node,node
75
76           Only nodes present in this node list will be allowed to start a
77           galera instance. The galera node names listed in this address are
78           expected to match valid pacemaker node names. If both names need to
79           differ, you must provide a mapping in option cluster_host_map.
80
81           (required, string, no default)
82
83       cluster_host_map
84           A mapping of pacemaker node names to galera node names.
85
86           To be used when both pacemaker and galera names need to differ,
87           (e.g. when galera names map to IP from a specific network
88           interface) This takes the form of:
89           pcmk1:node.1.galera;pcmk2:node.2.galera;pcmk3:node.3.galera
90
91           where the galera resource started on node pcmk1 would be named
92           node.1.galera in the wsrep_cluster_address
93
94           (optional, string, no default)
95
96       check_user
97           Cluster check user.
98
99           (optional, string, no default)
100
101       check_passwd
102           Cluster check user password. Empty passwords are ignored unless the
103           parameter "check_passwd_use_empty" is set to 1.
104
105           (optional, string, no default)
106
107       check_passwd_use_empty
108           Use an empty "check_passwd" password. If this parameter is set to
109           1, "check_passwd" will be ignored and an empty password is used
110           when calling the "mysql" client binary.
111
112           (optional, boolean, default 0)
113
114       two_node_mode
115           If running in a 2-node pacemaker cluster, rely on pacemaker quorum
116           to allow automatic recovery even when the other node is
117           unreachable. Use it with caution! (and fencing)
118
119           (optional, boolean, default false)
