rabbitmq3.8.16 configure cluster with peer_discovery_backend

[yang.li]

Hi,

    In CentOS7.9, I want to use rabbitmq.3.8.16 to create a cluster with 3 nodes. But I have some troubles.

1.  rabbitmq3.8.16 does not have rabbitmq.conf confure file in /etc/rabbitmq. However rabbitmq-defaults have few contents. Where can am I find the configure file template of rabbitmq.conf ?

2. Continue 1, according to rabbitmq.conf I found with Google, I made few changes for cluster configuration:

listeners.tcp.default = 5672

default_user = rabbitmq

default_pass = kpYlooMJ

loopback_users.guest = false

cluster_partition_handling = pause_minority

management.listener.port = 15672

heartbeat = 120

cluster_formation.peer_discovery_backend = rabbit_peer_discovery_classic_config

cluster_formation.classic_config.nodes.1 = rabbit@host1

cluster_formation.classic_config.nodes.2 = rabbit@host2

cluster_formation.classic_config.nodes.3 = rabbit@host3

When I run "rabbitmq-server", after some minutes, the cluster_status never change. How should I do configure cluster with peer_discovery_backend in rabbitmq3.8.16?

Example host1:

[root@host1 ~]# rabbitmqctl cluster_status
