Cause

rabbitmq Starter ikke op, når IPv6 er deaktiveret, og vrapid derfor er nede

 

Resolution

Løsning:

  1. Genaktiver IPV6, sørg for, at vrapid er oppe, opret forbindelse til vProxy som administrator , og su til rod:

    sudo su -

  2. Opret en kopi af rabbitmq.conf:

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

  3. Tjek de aktuelle listere:

    rabbitmq-diagnostics listeners

    Eksempel:

    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. Rediger filen rabbitmq.config for at fjerne ipv6 listner:

    vi /etc/rabbitmq/rabbitmq.config

    Fra:

    ######################################

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

######################################
######################################

    Til

    ######################################



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


######################################
######################################

  5. Genstart vProxy:

    reboot

  6. Bekræft, at kanin- og vrapid-tjenester er oppe at køre:

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

  7. Kontroller forbindelsen på port 9090 ved hjælp af curl-kommandoen:

    curl -v localhost:9090
