rabbitmq Falha ao inicializar quando o IPv6 está desativado e, devido a isso, o vRapid fica inativo

Solução temporária:

1. Reative o IPV6, certifique-se de que o vRapid esteja ativo, conecte-se ao vProxy como administrador e su Para rootear:

   sudo su -

2. Crie uma cópia de rabbitmq.conf:

   cp -P /etc/rabbitmq/rabbitmq.config /etc/rabbitmq/rabbitmq.config.orig

3. Confira os listners atuais:

   rabbitmq-diagnostics listeners

   Exemplo:

   Interface: 127.0.0.1, port: 5672, protocol: amqp, purpose: AMQP 0-9-1 and AMQP 1.0
   Interface: [::1], port: 5672, protocol: amqp, purpose: AMQP 0-9-1 and AMQP 1.0

4. Modifique o arquivo rabbitmq.config para remover o listner ipv6:

   vi /etc/rabbitmq/rabbitmq.config

   De:

   ######################################
   
   [
   {rabbit,
   [{tcp_listeners,
   [{"127.0.0.1", 5672}, {"::1", 5672}]}]
   }
   ].
   
   ######################################
   ######################################

   Para

   ######################################
   
   
   
   [
   {rabbit,
   [{tcp_listeners,
   [{"127.0.0.1", 5672}]}]
   }
   ].
   
   
   ######################################
   ######################################

5. Reinicialize o vProxy:

   reboot

6. Confirme se os serviços rabbit e vrapid estão em execução:

   systemctl status rabbitmq-server.service
   systemctl status vrapid.service

7. Verifique a conectividade na porta 9090 usando o comando curl:

   curl -v localhost:9090
