SYNOPSIS

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)

           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.

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" \
