Percona - Não é possível iniciar o mysql após a reinicialização

  • 772

Acabei de configurar um cluster percona xtradb no Ubuntu com 2 nós.

Isto é o que eu fiz.

  1. lançou 2 novos servidores.
  2. Cluster percona instalado em ambos os nós.
  3. Parou o mysql em ambos os nós.

No servidor1:

/etc/mysql/percona-xtradb-cluster.conf.d/wsrep.cnf
wsrep_cluster_address=gcomm://172.31.5.172,172.31.13.81
binlog_format=ROW
wsrep_slave_threads= 8
wsrep_log_conflicts
innodb_autoinc_lock_mode=2
wsrep_node_address=172.31.5.172
wsrep_cluster_name=pxc-cluster
pxc_strict_mode=DISABLED
wsrep_sst_method=xtrabackup-v2
wsrep_sst_auth="sstuser:s3cretPass"

No Servidor 2:

/etc/mysql/percona-xtradb-cluster.conf.d/wsrep.cnf
wsrep_cluster_address=gcomm://172.31.5.172,172.31.13.81
binlog_format=ROW
wsrep_slave_threads= 8
wsrep_log_conflicts
innodb_autoinc_lock_mode=2
wsrep_node_address=172.31.13.81
wsrep_cluster_name=pxc-cluster
pxc_strict_mode=DISABLED
wsrep_sst_method=xtrabackup-v2
wsrep_sst_auth="sstuser:s3cretPass"

No server1: /etc/init.d/mysql bootstrap-pxc Então o mysql foi iniciado.

CREATE USER 'sstuser'@'localhost' IDENTIFIED BY 's3cretPass';
GRANT PROCESS, RELOAD, LOCK TABLES, REPLICATION CLIENT ON *.* TO 'sstuser'@'localhost';
FLUSH PRIVILEGES;

No Servidor 2:

service mysql start

A partir de agora sem problemas, testei a replicatina. Então eu reiniciei os dois nós.

Depois disso o mysql não inicia.

    Sim Rick está certo. Como todos os nós estão inativos, você precisa inicializar o cluster novamente.

    Você parou todos os nós normalmente.

    Se você sabe qual é o último (nó) parado, escolha este nó também bootstrap e inicie outro nó.

    Mas se você não se lembrar do último nó que você desligou, abra grastate.dat (localize no diretório mysql) de todos os nós e compare o número seqno dentro e escolha um nó que tenha um número maior e inicie este nó primeiro. Se você escolher o nó errado para bootstrap, outro nó deverá remover todos os dados e solicitar novamente ao SST. por isso tem cuidado

  2. Para saber em qual nó foi a última inicialização do cluster, supondo que foi digitado manualmente na linha de comando do Linux, você pode usar o comando linux $ history em TODOS os nós do cluster, e ver qual nó teve o comando mais recente no histórico: systemctl start [email protected]
