Cause

rabbitmq Starter ikke når IPv6 er deaktivert, og på grunn av dette er vrapid nede

 

Resolution

Omgåelse av problemet:

  1. Aktiver IPV6 på nytt sørg for at vrapid er oppe, koble til vProxy som administrator og su Slik roter:

    sudo su -

  2. Opprett en kopi av rabbitmq.conf:

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

  3. Sjekk gjeldende lister:

    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. Endre rabbitmq.config-filen for å fjerne ipv6 listner:

    vi /etc/rabbitmq/rabbitmq.config

    Fra:

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

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

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

    Hvis du vil

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



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


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

  5. Start vProxy på nytt:

    reboot
