Optional: Changing the Ambari Server-Agent Port
By default, Ambari Server uses port 8187 to communicate with Ambari Agents. To change the port number, you must edit the Ambari properties file.
Ambari Server should not be running when you change port numbers. Edit
ambari.properties before you start Ambari Server the first time or stop
Ambari Server before editing properties.
Steps
On the Ambari Server host, open
/etc/ambari-server/conf/ambari.propertieswith a text editor.Add the following properties and set them to your desired port values:
security.server.two_way_ssl.port=5222 security.server.one_way_ssl.port=5223
On every Ambari Agent host, open
/etc/ambari-agent/conf/ambari-agent.iniwith a text editor.Add the following properties and set them to your desired port values:
url_port=5223 secured_url_port=5222
Start or re-start the Ambari Server. Ambari Server now accesses Ambari Agents via the newly configured port:
http://<your.ambari.server>:<port_number>
