NAME

6       ocf_heartbeat_mysql - Manages a MySQL database instance
7

SYNOPSIS

9       mysql [start | stop | status | monitor | promote | demote | meta-data |
10             validate-all]
11

DESCRIPTION

13       Resource script for MySQL. May manage a standalone MySQL database, a
14       clone set with externally managed replication, or a complete
15       master/slave replication setup. Note, when master/slave replication is
16       in use, the resource must be setup to use notifications. Set
17       'notify=true' in the metadata attributes when defining a MySQL
18       master/slave instance.
19
20       While managing replication, the default behavior is to use uname -n
21       values in the change master to command. Other IPs can be specified
22       manually by adding a node attribute
23       ${INSTANCE_ATTR_NAME}_mysql_master_IP giving the IP to use for
24       replication. For example, if the mysql primitive you are using is
25       p_mysql, the attribute to set will be p_mysql_mysql_master_IP.

98           (optional, string, no default)
99
100       replication_user
101           MySQL replication user. This user is used for starting and stopping
102           MySQL replication, for setting and resetting the master host, and
103           for setting and unsetting read-only mode. Because of that, this
104           user must have SUPER, REPLICATION SLAVE, REPLICATION CLIENT,
105           PROCESS and RELOAD privileges on all nodes within the cluster.
106           Mandatory if you define a master-slave resource.
107
108           (optional, string, default "root")
109
110       replication_passwd
111           MySQL replication password. Used for replication client and slave.
112           Mandatory if you define a master-slave resource.
113
114           (optional, string, no default)
115
116       replication_port
117           The port on which the Master MySQL instance is listening.
118
119           (optional, string, default "3306")
120
121       replication_master_ssl_ca
122           The SSL CA certificate to be used for replication over SSL.
123
124           (optional, string, no default)
125
126       replication_master_ssl_cert
127           The SSL CA certificate to be used for replication over SSL.
128
129           (optional, string, no default)
130
131       replication_master_ssl_key
132           The SSL certificate key to be used for replication over SSL.
133
134           (optional, string, no default)
135
136       max_slave_lag
137           The maximum number of seconds a replication slave is allowed to lag
138           behind its master. Do not set this to zero. What the cluster
139           manager does in case a slave exceeds this maximum lag is determined
140           by the evict_outdated_slaves parameter.
141
142           (optional, integer, default 3600)
143
144       evict_outdated_slaves
145           If set to true, any slave which is more than max_slave_lag seconds
146           behind the master has its MySQL instance shut down. If this
147           parameter is set to false in a primitive or clone resource, it is
148           simply ignored. If set to false in a master/slave resource, then
149           exceeding the maximum slave lag will merely push down the master
150           preference so the lagging slave is never promoted to the new
151           master.
152
153           (optional, boolean, default false)
154
155       reader_attribute
156           An attribute that the RA can manage to specify whether a node can
157           be read from. This node attribute will be 1 if it's fine to read
158           from the node, and 0 otherwise (for example, when a slave has
159           lagged too far behind the master).
160
161           A typical example for the use of this attribute would be to tie a
162           set of IP addresses to MySQL slaves that can be read from.
163
164           This parameter is only meaningful in master/slave set
165           configurations.
166
167           (unique, optional, string, default "readable")
