Note: Cluster 2 cluster replication using PXC requires that server_id and binlog settings are identical on all nodes of the slave cluster. You can achieve this by creating a slave config template:
PXC 5.6:
sudo cp /usr/share/cmon/templates/my.cnf.galera /etc/cmon/templates/my.cnf.galera-binlog-slave
PXC 5.7:
sudo cp /usr/share/cmon/templates/my57.cnf.galera /etc/cmon/templates/my.cnf.galera-binlog-slave
and add/change in the [mysqld] section:
server_id=123456
binlog_format=ROW
log_bin=binlog
log_slave_updates=ON
gtid_mode=ON
enforce_gtid_consistency=ON
relay_log=relay-bin
expire_logs_days=7
Then select the my.cnf.galera-binlog-slave template in the Create Slave Cluster Deployment dialog.
Master Cluster
We also recommend you create the Galera Master Cluster using the same server_id and binlog settings by creating a master template:
PXC 5.6:
sudo cp /usr/share/cmon/templates/my.cnf.galera /etc/cmon/templates/my.cnf.galera-binlog-master
PXC 5.7:
sudo cp /usr/share/cmon/templates/my57.cnf.galera /etc/cmon/templates/my.cnf.galera-binlog-master
and add/change in the [mysqld] section:
server_id=567890
binlog_format=ROW
log_bin=binlog
log_slave_updates=ON
gtid_mode=ON
enforce_gtid_consistency=ON
relay_log=relay-bin
expire_logs_days=7
Then select the my.cnf.galera-binlog-master template in the Create Cluster Deployment dialog.

Thanks for sharing this detailed setup! The reminder about keeping server_id and binlog settings identical across all nodes for PXC slave clusters is really helpful — especially when dealing with GTID and replication consistency. Creating separate templates for the master and slave clusters definitely makes the deployment process smoother. Really appreciate the clarity in these steps!
After adjusting both templates, choose them in the appropriate deployment dialogs.
Creating a slave cluster using cluster-to-cluster replication helps improve scalability and disaster recovery. kuaishou apk download new version data to stay synchronized across clusters while reducing load on the primary one. Proper configuration and monitoring are key to maintaining consistency and performance.
To set up Cluster-to-Cluster replication in PXC, both master and slave clusters must have consistent binlog and GTID settings configured via custom templates. You create separate templates for master and slave, ensuring options like binlog_format=ROW, log_bin, and gtid_mode=ON are enabled, fun with dinosaur game. Then select the appropriate template during cluster deployment to ensure replication works correctly.
This was a solid and informative walkthrough—cluster-to-cluster replication can feel pretty complex, but you explained the process in a way that makes it much easier to grasp, especially the importance of synchronization, failover handling, and data consistency. I also liked how you pointed out potential pitfalls, because that’s often what trips people up in real-world setups. From my experience, getting replication right can significantly improve reliability and scalability, which is critical for growing systems. It even reminds me of platforms like Estatus Beca Rita Cetina, where consistent and accurate data availability across systems is essential for users accessing real-time information. In your opinion, what’s the most common mistake people make when setting up cluster-to-cluster replication for the first time?
Why is it essential to use the same server_id and binlog settings on all nodes of the slave cluster for cluster replication in PXC drive mad?
