RabbitMQ Can't join Cluster and enable Plugin

Question

I try to setting cluster for my RabbitMQ , but when join cluster it error i don't know why, spent one day to find solution but still no hope. ( I'm using Window and install with all default option).

Promblem 1: Can't join Cluster: I have 2 computer install Rabbit:

• rabbit@HOANGQUOCVI2118
• ALO-PC

I able to telnet port of ALO-PC , turn off firewall too, but can't join Cluster by this command:

c:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.5.6\sbin>rabbitmqctl join_cluster rabbit@ALO-PC Clustering node rabbit@HOANGQUOCVI2118 with 'rabbit@ALO-PC' ...

Error: unable to connect to nodes ['rabbit@ALO-PC']: nodedown

DIAGNOSTICS

attempted to contact: ['rabbit@ALO-PC']

rabbit@ALO-PC: * connected to epmd (port 4369) on ALO-PC * epmd reports node 'rabbit' running on port 25672 * TCP connection succeeded but Erlang distribution failed * suggestion: hostname mismatch? * suggestion: is the cookie set correctly? * suggestion: is the Erlang distribution using TLS?

current node details: - node name: 'rabbitmq-cli-248@HOANGQUOCVI2118' - home dir: C:\Users\quocviet - cookie hash: 0B/cSw97VtsfE3zp8Y+Jbg==

Promblem 2: Can't enable plugin:

Federation:

c:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.5.6\sbin>rabbitmq-plugins enable rabbitmq_federation

The following plugins have been enabled:
rabbitmq_federation

Applying plugin configuration to rabbit@HOANGQUOCVI2118... failed. Error: {noproc, {gen_server,call, [rabbit_sup, {start_child, {rabbit_federation_sup, {rabbit_federation_sup,start_link,[]}, transient,4294967295,worker, [rabbit_federation_sup]}}, infinity]}}

Shovel plugin:

c:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.5.6\sbin>rabbitmq-plugi ns disable rabbitmq_shovel The following plugins have been disabled:
rabbitmq_shovel

Applying plugin configuration to rabbit@HOANGQUOCVI2118... failed. Error: noproc

Please help me solve this case.

Answer 1

About your second problem, it looks like the Erlang node is running, but the RabbitMQ application is stopped on this node.

After your attempts to cluster nodes, did you restart RabbitMQ?
