Verifying infrastructure operation

Verify the database cluster and Kibana web interface operation.

Procedure 7.1. Verifying the database cluster

  1. Determine the Galera container name:

    # lxc-ls | grep galera
    infra1_galera_container-4ed0d84a
    
  2. Access the Galera container:

    # lxc-attach -n infra1_galera_container-4ed0d84a
    
  3. Run the MariaDB client, show cluster status, and exit the client:

    # mysql -u root -p
    MariaDB> show status like 'wsrep_cluster%';
    +--------------------------+--------------------------------------+
    | Variable_name            | Value                                |
    +--------------------------+--------------------------------------+
    | wsrep_cluster_conf_id    | 3                                    |
    | wsrep_cluster_size       | 3                                    |
    | wsrep_cluster_state_uuid | bbe3f0f6-3a88-11e4-bd8f-f7c9e138dd07 |
    | wsrep_cluster_status     | Primary                              |
    +--------------------------+--------------------------------------+
    MariaDB> exit
    

    The wsrep_cluster_size field should indicate the number of nodes in the cluster and the wsrep_cluster_status field should indicate primary.
