ERRO WSREP`: gcs/src/gcs.cpp:gcs_open():1379:` Falha ao abrir o canal 'test_cluster'

  • 772

Eu tenho três servidores que quero instalar o cluster do Galera neles, segui este link para instalá-lo e configurá-lo. mas quando quero iniciar o primeiro servidor, recebo este erro:

root@node107:/home/debian# service mysql start --wsrep-new-clusterping 
Job for mysql.service failed. See 'systemctl status mysql.service' and 'journalctl -xn' for details.

e :

root@node107:/home/debian# journalctl -xn

estes são arquivos de configuração para os três servidores:

Não entendo o que perdi. O que devo fazer?

  1. Best Answer

    Devemos iniciar o primeiro nó sem o parâmetro abaixo em my.cnf: wsrep_cluster_address="gcomm://192.168.120.107,192.168.120.111,192.168.120.117"

    Em seguida, inicie os outros nós normalmente:

    /etc/init.d/mysql start

    O primeiro nó deve iniciar normalmente como os outros.

  2. Inicialize o primeiro nó com a opção abaixo

    service mysql start --wsrep-new-cluster

    Certifique-se de ter as configurações abaixo em todos os arquivos de configuração:

    wsrep_cluster_address="gcomm://192.168.120.107,192.168.120.111,192.168.120.117"

    Em seguida, inicie os outros nós usandoservice mysql start

    Ambos os nós serão sincronizados com o nó de bootstrap.
