Réplica não inicia

  • 772

Estou tentando configurar uma réplica primária-secundária. Isso é para fazer uma migração sem tempo de inatividade do primeiro nó para o segundo nó nos próximos dias.

O nó primário foi configurado, a configuração foi atualizada, adicionei o keyfile. Fiz o mesmo com o nó secundário.

Também inicializei a replicação, adicionei o nó secundário à replicação. Posso ver um ping e uptime, mas o nó secundário está preso em “STARTUP”.

No entanto, não há configuração de réplica no nó secundário. Além disso, ele está vomitando isso em todo o log de erros repetidamente.

Nó Secundário (Logs):

    Certo, então quando você criar a lista de réplicas, certifique-se de que cada host possa se comunicar com o outro. Isso significa que os nomes de host (DNS) ou endereços IP devem ser especificados corretamente.

    Minha configuração de réplica padrão incluía o nome do host do servidor primário como "my-ubuntu-server". Então, quando o nó secundário tentou se comunicar de volta, não conseguiu.

    Gostaria que o registro fosse melhor.
