Install a Nacos Cluster

A production Nacos deployment should use multiple nodes and an external supported database rather than embedded standalone storage.

List every node in cluster.conf using addresses reachable from all peers. Configure identical database connection settings and application properties on each node, then start the nodes one at a time and inspect their logs.

Place a load balancer or reverse proxy in front of client-facing endpoints, but preserve the ports and protocols required by the selected Nacos release. Nacos 2.x introduced additional gRPC ports relative to the main server port, so firewall rules must match the actual version.

Verify cluster membership, namespace and configuration replication, service registration, and client reconnection when one node stops. Protect the console with strong authentication and network restrictions. Back up the external database, monitor heap, thread pools, request latency, database connectivity, and disk logs, and test rolling upgrades before applying them to production.
