NAME

       ocf_heartbeat_mysql - Manages a MySQL database instance

SYNOPSIS

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

DESCRIPTION

       Resource script for MySQL. May manage a standalone MySQL database, a clone set with externally managed replication, or a complete
       master/slave replication setup.

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/lib/mysqld/mysqld.sock)

       test_table
	   Table to be tested in monitor statement (in database.table notation) (optional, string, default mysql.user)

       test_user
	   MySQL test user (optional, string, default root)

       test_passwd
	   MySQL test user password (optional, string, no default)

       enable_creation
	   If the MySQL database does not exist, it will be created (optional, integer, 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)

       replication_user
	   MySQL replication user. This user is used for starting and stopping MySQL replication, for setting and resetting the master host, and
	   for setting and unsetting read-only mode. Because of that, this user must have SUPER, REPLICATION SLAVE, REPLICATION CLIENT, and
	   PROCESS privileges on all nodes within the cluster.	(optional, string, no default)

       replication_passwd
	   MySQL replication password. Used for replication client and slave.  (optional, string, no default)

       replication_port
	   The port on which the Master MySQL instance is listening.  (optional, string, default 3306)

       max_slave_lag
	   The maximum number of seconds a replication slave is allowed to lag behind its master. Do not set this to zero. What the cluster
	   manager does in case a slave exceeds this maximum lag is determined by the evict_outdated_slaves parameter.	(optional, integer,
	   default 3600)

       evict_outdated_slaves
	   If set to true, any slave which is more than max_slave_lag seconds behind the master has its MySQL instance shut down. If this
	   parameter is set to false in a primitive or clone resource, it is simply ignored. If set to false in a master/slave resource, then
	   exceeding the maximum slave lag will merely push down the master preference so the lagging slave is never promoted to the new master.
	   (optional, boolean, default false)

SUPPORTED ACTIONS

       This resource agent supports the following actions (operations):

       start

	   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: 120.

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

       notify
	   Suggested minimum timeout: 90.

       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

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

	   primitive p_mysql ocf:heartbeat:mysql 
	     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_mysql p_mysql 
	     meta notify="true" interleave="true"
