Question

我有两个在不同服务器上使用docker的RabbitMQ节点：

rabbitmq-1.myhost.com（管理员） rabbitmq-2.myhost.com（从站）

我尝试加入这个奴隶，以便以此来创建一个两节点集群：

但是我得到了

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

编辑：在添加上一行之前，我先复制/ etc / hosts：

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]}]}

但是当我启动docker容器时我得到了这个信息：

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

Answer 1

我终于得到了将别名（rabbitmq-1和rabbitmq-2）的两个IP添加到/ etc / hosts，并在从节点（rabbitmqctl-2）中添加了以下命令：

rabbitmqctl stop_app

rabbitmqctl reset

rabbitmqctl join_cluster rabbit@rabbitmq-1

rabbitmqctl start_app

rabbitmqctl cluster_status

RabbitMQ集群：无法将从节点加入主节点
