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.
Create a new database on the second node:
mysql@pxc2> CREATE DATABASE percona; Query OK, 1 row affected (0.01 sec)
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)
Insert records on the first node:
mysql@pxc1> INSERT INTO percona.example VALUES (1, 'percona1'); Query OK, 1 row affected (0.02 sec)
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)
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.
