Synopsis

  • Galera Cluster for MySQL/MariaDB (including MariaDB Galera Cluster and Percona XtraDB Cluster) uses TCP port 4567 for primary replication/group communication between nodes.
  • Example: Percona XtraDB Cluster 8.0 and MariaDB Server with Galera default to 4567/TCP for wsrep traffic (with 4444 and 4568 used for SST/IST).
  • Ruby’s Sinatra web framework binds to TCP 4567 by default for its development server.
  • Middleman (a Ruby static site generator built on Sinatra) also serves on TCP 4567 by default.
  • IANA assigns 4567/TCP to TRAM (Tree-based Reliable Multicast), historically used by Sun’s Java Reliable Multicast Service (JRMS).
