2.7. Assign Network Ports

VoltDB uses a number of network ports for functions such as internal communications, client connections, rejoin, database replication, and so on. For these features to perform properly, the ports must be open and available. Review the following list of ports to ensure they are open and available (that is, not currently in use).

FunctionDefault Port Number
Client Port21212
Admin Port21211
Web Interface Port (httpd)8080
Internal Server Port3021
Log Port4560
JMX Port9090
Replication Port5555, 5556, 5557
Zookeeper port2181

Alternately, you can reassign the port numbers that VoltDB uses. See Section A.5, “Network Ports” for a description of the ports and how to reassign them.
