11
13 Resource script for MariaDB.
14
15 Manages a complete master/slave replication setup with GTID, for
16 simpler uses look at the mysql resource agent which supports older
17 replication forms which mysql and mariadb have in common.
18
19 The resource must be setup to use notifications. Set 'notify=true' in
20 the metadata attributes when defining a MariaDB master/slave instance.
21
22 The default behavior is to use uname -n values in the change master to
23 command. Other IPs can be specified manually by adding a node attribute
24 ${INSTANCE_ATTR_NAME}_mysql_master_IP giving the IP to use for
25 replication. For example, if the mariadb primitive you are using is
26 p_mariadb, the attribute to set will be p_mariadb_mysql_master_IP.

172
174 The following is an example configuration for a mariadb resource using
175 the crm(8) shell:
176
177 primitive p_mariadb ocf:heartbeat:mariadb \
178 params \
179 node_list=string \
180 op monitor depth="0" timeout="30s" interval="20s" \
181 op monitor role="Master" depth="0" timeout="30s" interval="10s" \
182 op monitor role="Slave" depth="0" timeout="30s" interval="30s"
183
184 ms ms_mariadb p_mariadb \
185 meta notify="true" interleave="true"
186
188 The following is an example configuration for a mariadb resource using
189 pcs(8)
190
191 pcs resource create p_mariadb ocf:heartbeat:mariadb \
192 node_list=string \
