RabbitMQ master and slave sync

You can determine which slaves are synchronised with the          following rabbitmqctl invocation:

rabbitmqctl list_queues name slave_pids synchronised_slave_pids

       

You can manually synchronise a queue with:

rabbitmqctl sync_queue name

       

And you can cancel synchronisation with:

rabbitmqctl cancel_sync_queue name

                 These features are also available through the management plugin

例如：

[root@TEST1 ~]# rabbitmqctl list_queues pid slave_pids synchronised_slave_pids
Listing queues ...
<[email protected]>    [<[email protected]>]    [<[email protected]>]

MASTER：rabbit@TEST2

SLAVE：rabbit@TEST1

在rabbit@TEST2上停止master，即rabbitmqctl stop_app

[root@TEST1 ~]# rabbitmqctl list_queues pid slave_pids synchronised_slave_pids
Listing queues ...
<[email protected]>    []    []

原来的slave已经成为了master，即master为rabbit@TEST1

在rabbit@TEST2上执行rabbitmqctl start_app

[root@TEST1 ~]# rabbitmqctl list_queues pid slave_pids synchronised_slave_pids
Listing queues ...
<[email protected]>    [<[email protected]>]    [<[email protected]>]

MASTER：rabbit@TEST1

SLAVE：rabbit@TEST2

结论：

broker master和slave能够正常切换
