This all boils down to each host having different options in it's
my.cnf file.
There is an official augeas lens for editing mysql's my.cnf file since a
couple of days (not in any release yet).
If this can be of any help, I used this code for a basic "1 master-1
slave" setup on a few projects:
class mysql::master inherits mysql::server {
augeas { "my.cnf/replication":
context => "/files/etc/my.cnf/mysqld/",
changes => [
"set log-bin mysql-bin",
"set server-id ${mysql_serverid}",
"set expire_logs_days 7",
"set max_binlog_size 100M"
],
}
}
class mysql::slave inherits mysql::master {
augeas { "my.cnf/slave-replication":
context => "/files/etc/my.cnf/mysqld/",
changes => [
"set relay-log /var/lib/mysql/mysql-relay-bin",
"set relay-log-index /var/lib/mysql/mysql-relay-bin.index",
"set relay-log-info-file /var/lib/mysql/relay-log.info",
"set relay_log_space_limit 2048M",
"set max_relay_log_size 100M",
"set master-host ${mysql_masterhost}",
"set master-user ${mysql_masteruser}",
"set master-password ${mysql_masterpw}",
"set report-host ${hostname}"
],
}
}
I used a home-brew augeas lens though. I'm not sure the paths are
exactly the same with the official one.
Cheers,
Marc
