如何将rabbitmq集群中的某个节点移除.

首先将要移除的节点停机.

root@rabbitmq-03:~# rabbitmqctl stop

Stopping and halting node 'rabbit@rabbitmq-03' ...

然后执行如下操作.

在主节点,也就是发起进群的主机上进行节点的移除.

root@rabbitmq-01:/var/lib/rabbitmq# rabbitmqctl  -n rabbit@rabbitmq-01 forget_cluster_node rabbit@rabbitmq-03

Removing node 'rabbit@rabbitmq-03' from cluster ...

 

下面是范例

rabbitmqctl -n hare @ mcnulty forget_cluster_node rabbit @ stringer

 

然后查看集群状态信息.

 

root@rabbitmq-01:/var/lib/rabbitmq# rabbitmqctl cluster_status

Cluster status of node 'rabbit@rabbitmq-01' ...

[{nodes,[{disc,['rabbit@rabbitmq-01','rabbit@rabbitmq-02']}]},

{running_nodes,['rabbit@rabbitmq-02','rabbit@rabbitmq-01']},

{cluster_name,<<"rabbit@rabbitmq-01">>},

{partitions,[]}]

 

发现rabbitmq3节点已经被移除.
