Starting from Appian 17.3, Appian has default ports configured to your setup based on the Port Usage documentation. These default ports can be modified on an on-premise Appian installation.
Follow the steps provided below to modify default ports on your on-premise Appian installation:
All the default ports for the components mentioned above apart from the Service Manager port can be modified from the appian-topology.xml file.
<topology port="5000"> <search-cluster port="<NEW_SEARCH_SERVER_PORT>"> <search-server/> </search-cluster> <kafkaCluster> <broker host="localhost" port="<NEW_KAFKA_PORT>"/> </kafkaCluster> <zookeeperCluster> <zookeeper host="localhost" port="<NEW_ZOOKEEPER_PORT>"/> </zookeeperCluster> <data-server-cluster> <data-server host="localhost" port="<NEW_DATA_SERVER_PORT>" rts-count="1"/> </data-server-cluster></topology>
The default port for the Service Manager can be modified by specifying the following property in the custom.properties file.
Once you have modified the default ports, please restart your on-premise Appian environment for the changes to take effect.
This article applies to all versions of Appian running 17.3 or later.
