ocf_heartbeat_galera - Manages a galara instance

galera [start | stop | status | monitor | promote | demote | meta-data | validate-all]

Resource script for managing galara database.

binary

Location of the MySQL server binary

(optional, string, no default)

client_binary

Location of the MySQL client binary

(optional, string, no default)

config

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)

(optional, string, no default)

log

The logfile to be used for mysqld.

(optional, string, no default)

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, default "root")

check_passwd

Cluster check user password

(optional, string, no default)

This resource agent supports the following actions (operations):

start

Starts the resource. Suggested minimum timeout: 120s.

stop

Stops the resource. Suggested minimum timeout: 120s.

status

Performs a status check. Suggested minimum timeout: 60s.

monitor

Performs a detailed status check. Suggested minimum timeout: 30s. Suggested interval: 20s.

monitor (Master role)

Performs a detailed status check. Suggested minimum timeout: 30s. Suggested interval: 10s.

monitor (Slave role)

Performs a detailed status check. Suggested minimum timeout: 30s. Suggested interval: 30s.

promote

Promotes the resource to the Master role. Suggested minimum timeout: 300s.

demote

Demotes the resource to the Slave role. Suggested minimum timeout: 120s.

validate-all

Performs a validation of the resource configuration. Suggested minimum timeout: 5s.

meta-data

Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s.

The following is an example configuration for a galera resource using the crm(8) shell:

primitive p_galera ocf:heartbeat:galera \


  params \


    wsrep_cluster_address=string \


  op monitor depth="0" timeout="30s" interval="20s" \


  op monitor role="Master" depth="0" timeout="30s" interval="10s" \


  op monitor role="Slave" depth="0" timeout="30s" interval="30s" 

ms ms_galera p_galera \


  meta notify="true" interleave="true"

The following is an example configuration for a galera resource using pcs(8)

pcs resource create p_galera ocf:heartbeat:galera \


  wsrep_cluster_address=string \


  op monitor depth="0" timeout="30s" interval="20s" \


  op monitor role="Master" depth="0" timeout="30s" interval="10s" \


  op monitor role="Slave" depth="0" timeout="30s" interval="30s" --master
