RABBITMQ群集：无法将从属节点连接到Master

Question

i在不同的服务器中使用Docker有两个RabbitMQ节点：

rabbitmq-1.myhost.com（师父） rabbitmq-2.myhost.com（奴隶）

我尝试加入从属来掌握以下创建两个节点群集的掌握：

root@rabbitmq-2:/#  rabbitmqctl stop_app
Stopping rabbit application on node rabbit@rabbitmq-2 ...
root@rabbitmq-2:/# rabbitmqctl join_cluster [email protected]

但我得到：

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]}]}

Edit：我在添加上一行之前复制我的 /ett /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

但是，当我启动Docker容器时，我会得到这个：

Attaching to rabbitmq-2

rabbitmq-2 | 11:02:14.540 [error]

rabbitmq-2 |

rabbitmq-2 | BOOT FAILED

rabbitmq-2 | ===========

rabbitmq-2 | 11:02:14.542 [error] BOOT FAILED

rabbitmq-2 | 11:02:14.543 [error] ===========

rabbitmq-2 | 11:02:14.543 [error] ERROR: epmd error for host rabbitmq-2: address (cannot connect to host/port)

rabbitmq-2 | ERROR: epmd error for host rabbitmq-2: address (cannot connect to host/port)

Answer 1

i最终将其添加到 /etc /hosts，并在从属节点（rabbitmqctl-2）中添加两个带有别名（RabbitMQ-1和RabbitMQ-2）的IP（RabbitMQ-1和RabbitMQ-2）：

rabbitmqctl stop_app

rabbitmqctl reset

rabbitmqctl join_cluster rabbit@rabbitmq-1

rabbitmqctl start_app

rabbitmqctl cluster_status

Answer 2

您可以检查主节点的名称：

rabbitmqctl status | grep name 我希望在这里看到一个简短的名称，没有域名，例如'Rabbit@Rabbitmq-1' 尝试在加入命令中使用它：

rabbitmqctl join_cluster rabbit@rabbitmq-1 或命名节点，请随心所欲：

vi /etc/rabbitmq/rabbitmq-env.conf dedit行

NODENAME=rabbit@rabbitmq-1

至

[email protected]

并重新启动：

sudo systemctl restart rabbitmq-server 现在您可以尝试与完整的FQDN
