RabbitMQ集群:无法加入从节点到主节点
RabbitMQ集群:无法加入从节点到主节点
提问于 2020-08-06 14:05:23
我在不同的服务器中使用了两个RabbitMQ节点：
rabbitmq 1.myhost.com(主)rabbitmq-2 myhost.com(奴隶)
我尝试加入从服务器创建一个两个节点集群，如下所示：
root@rabbitmq-2:/# rabbitmqctl stop_app
Stopping rabbit application on node rabbit@rabbitmq-2 ...
root@rabbitmq-2:/# rabbitmqctl join_cluster rabbit@rabbitmq-1.myhost.com但我明白：
root@rabbitmq-2:/# rabbitmqctl join_cluster rabbitmq-1.myhost.com
Clustering node rabbit@rabbitmq-2 with rabbitmq-1.myhost.com
Error:
{:badarg, [{:rpc, :rpcify_exception, 2, [file: 'rpc.erl', line: 467]}, {:rpc, :call, 5, [file: 'rpc.erl', line: 410]}, {:lists, :foldl, 3, [file: 'lists.erl', line: 1263]}, {:rabbit_mnesia, :discover_cluster, 1, [file: 'src/rabbit_mnesia.erl', line: 804]}, {:rabbit_mnesia, :join_cluster, 2, [file: 'src/rabbit_mnesia.erl', line: 236]}]}编辑:在添加前一行：之前，我复制/etc/主机
root@rabbitmq-2:/# cat /etc/hosts
127.0.0.1localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
XX.XX.XX.XX rabbitmq-1.myhost.com rabbitmq-1
YY.YY.YY.YY rabbitmq-2.myhost.com rabbitmq-2但当我启动我的码头集装箱时，我会得到这个：

最后，我让它将别名(rabbitmq-1和rabbitmq-2)的两个IP添加到/etc/host中，并在从节点(rabbitmqctl-2)中使用以下命令：
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster rabbit@rabbitmq-1
rabbitmqctl start_app
rabbitmqctl cluster_status页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
