Verifying Replication

Use the following procedure to verify replication by creating a new database on the second node, creating a table for that database on the third node, and adding some records to the table on the first node.

  1. Create a new database on the second node:

    mysql@pxc2> CREATE DATABASE percona;
    Query OK, 1 row affected (0.01 sec)
    
  2. Create a table on the third node:

    mysql@pxc3> USE percona;
    Database changed
    
    mysql@pxc3> CREATE TABLE example (node_id INT PRIMARY KEY, node_name VARCHAR(30));
    Query OK, 0 rows affected (0.05 sec)
    
  3. Insert records on the first node:

    mysql@pxc1> INSERT INTO percona.example VALUES (1, 'percona1');
    Query OK, 1 row affected (0.02 sec)
    
  4. Retrieve rows from that table on the second node:

    mysql@pxc2> SELECT * FROM percona.example;
    +---------+-----------+
    | node_id | node_name |
    +---------+-----------+
    |       1 | percona1  |
    +---------+-----------+
    1 row in set (0.00 sec)
    

Next Steps

  • Consider installing ProxySQL on client nodes for efficient workload management across the cluster without any changes to the applications that generate queries. This is the recommended high-availability solution for Percona XtraDB Cluster.

    For more information, see Load balancing with ProxySQL.

  • Percona Monitoring and Management is the best choice for managing and monitoring Percona XtraDB Cluster performance. It provides visibility for the cluster and enables efficient troubleshooting.
