ClustrixDB requires a number of ports to allow internode communication. Depending on your specific deployment platform, you can:
These network ports are required for communication between Xpand nodes. They must each be accessible by other nodes within the cluster.
Protocol | Port(s) | Use | Reason |
---|---|---|---|
TCP | 22 | SSH | Administration and upgrade |
TCP, UDP | 2048 | Control Port | Xpand specialized administrative tool |
TCP, UDP | 2424 | Nanny Port | nanny - Xpand process manager |
TCP | 3306 | SQL | Database communication |
TCP | 7888 | clxdbi | Database interface for XpandGUI |
TCP, UDP | varies (see below) | Multiport | Xpand internode communication |
Starting at port 24379, (for both TCP and UDP), open the same number of ports as there are cores or hyper-threads licensed for a node. The maximum number of licensed cores per node is 32, hence the suggested maximum range of 24379 - 24410.
Xpand does not support mixed-mode usage of multiport. That is, all nodes must uniformly have multiport enabled (default) or disabled, or the nodes will be unable to form a cluster.
See Modifying Startup Configuration Options for instructions on how to disable multiport, if necessary.
These network ports are used to access Xpand externally from your applications and for cluster administration.
Protocol | Port | Use | Reason |
---|---|---|---|
TCP | 22 | SSH | Remote management and cluster access |
TCP | 8080* | HTTP | XpandGUI |
TCP | 3306 | SQL | Database access |
TCP | 3581 | Health Check | Heartbeat monitor for cluster |
*For root installation, XpandGUI uses port 80.
If you are using a firewall (like iptables) between the nodes, please open the specific ports.
