NAME

ocf_heartbeat_galera - Manages a galara instance

SYNOPSIS

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

DESCRIPTION

Resource script for managing galara database.

SUPPORTED PARAMETERS

binary Location of the MySQL server binary (optional, string, default "/usr/bin/mysqld_safe") client_binary Location of the MySQL client binary (optional, string, default "mysql") config Configuration file (optional, string, default "/etc/mysql/my.cnf") datadir Directory containing databases (optional, string, default "/var/lib/mysql") user User running MySQL daemon (optional, string, default "mysql") group Group running MySQL daemon (for logfile and directory permissions) (optional, string, default "mysql") log The logfile to be used for mysqld. (optional, string, default "/var/log/mysql.log") pid The pidfile to be used for mysqld. (optional, string, default "/var/run/mysqld/mysqld.pid") socket The socket to be used for mysqld. (optional, string, default "/var/run/mysqld/mysqld.sock") enable_creation If the MySQL database does not exist, it will be created (optional, boolean, default 0) 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)

SUPPORTED ACTIONS

This resource agent supports the following actions (operations): start Starts the resource. Suggested minimum timeout: 120. stop Stops the resource. Suggested minimum timeout: 120. status Performs a status check. Suggested minimum timeout: 60. monitor Performs a detailed status check. Suggested minimum timeout: 30. Suggested interval: 20. monitor (Master role) Performs a detailed status check. Suggested minimum timeout: 30. Suggested interval: 10. monitor (Slave role) Performs a detailed status check. Suggested minimum timeout: 30. Suggested interval: 30. promote Promotes the resource to the Master role. Suggested minimum timeout: 300. demote Demotes the resource to the Slave role. Suggested minimum timeout: 120. validate-all Performs a validation of the resource configuration. Suggested minimum timeout: 5. meta-data Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.

EXAMPLE CRM SHELL

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="30" interval="20" \ op monitor role="Master" depth="0" timeout="30" interval="10" \ op monitor role="Slave" depth="0" timeout="30" interval="30" ms ms_galera p_galera \ meta notify="true" interleave="true"

EXAMPLE PCS

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="30" interval="20" \ op monitor role="Master" depth="0" timeout="30" interval="10" \ op monitor role="Slave" depth="0" timeout="30" interval="30" --master
