1. Configure the carbon.xml files of the three profile to port offset.

   Core	Open the <IOTS_HOME>/conf/carbon.xml file and port offset the IoT Server's core profile by configuring the <Offset> attribute. Note Make sure not to have the same offset values as the broker or analytics profile. Example: Code Block <Offset>4</Offset> Now the HTTPS and HTTP ports of the core profile are 9447 and 9767.
   Analytics	Open the <IOTS_HOME>/wso2/analytics/conf/carbon.xml file and port offset the IoT Server's core profile by configuring the <Offset> attribute. Note Make sure not to have the same offset values as the broker or analytics profile. Code Block <Offset>5</Offset> Now the HTTPS and HTTP ports of the analytics profile are 9448 and 9768.
   Broker	Open the <IOTS_HOME>/wso2/broker/conf/carbon.xml file and port offset the IoT Server's core profile by configuring the <Offset> attribute. Note Make sure not to have the same offset values as the broker or analytics profile. Code Block <Offset>6</Offset> Now the HTTPS and HTTP ports of the broker profile are 9449 and 9769.

2. Open the <IOTS_HOME>/bin/iot -server.sh or iot-server.bat file configures the following properties:

   Analytics ports	By default the analytics profile is offset by 2. In step 1, you offset the analytics profile by 3 more again. Therefore, all the ports relevant to the analytics profile needs to be offset by 3 more. Example: Code Block -Diot.analytics.https.port="9448" \
   Broker ports	By default, the broker profile is offset by 3. In step 1, you offset the broker profile by 3 more. Therefore, all the ports relevant to the broker profile needs to be offset by 3. Example: Code Block -Dmqtt.broker.port="1889" \
   IoT core ports	By default the core profile is offset by 0. In step 1, you offset the broker profile by 4. Therefore, all the ports relevant to the core profile needs to be offset by 4. Example: Code Block -Diot.manager.https.port="9447" \ -Diot.core.https.port="9447" \ -Diot.keymanager.https.port="9447" \ -Diot.gateway.https.port="8247" \ -Diot.gateway.http.port="8284" \ -Diot.gateway.carbon.https.port="9447" \ -Diot.gateway.carbon.http.port="9767" \ -Diot.apimpublisher.https.port="9447" \ -Diot.apimstore.https.port="9447" \

3. Open the <IOTS_HOME>/wso2/analytics/bin/wso2 server.sh  or  or wso2server.bat file configures the following properties:

   Broker ports	By default, the broker profile is offset by 3. In step 1, you offset the broker profile by 3 more. Therefore, all the ports relevant to the broker profile needs to be offset by 3. Example: Code Block -Dmqtt.broker.port="1889" \
   IoT core ports	By default the core profile is offset by 0. In step 1, you offset the core profile by 4. Therefore, all the ports relevant to the core profile needs to be offset by 4. Example: Code Block -Diot.keymanager.https.port="9447" \ -Diot.gateway.https.port="8247" \

4. Configure following properties in the Open the <IOTS_HOME>/wso2/broker/conf/broker.xml file and configure the following properties:

   1. The port that refers to the IoT core in the hostURL attribute that is in the <authenticator class="org.wso2.carbon.andes.authentication.andes.OAuth2BasedMQTTAuthenticator"> class.
      Example: 

      Code Block

      <authenticator class="org.wso2.carbon.andes.authentication.andes.OAuth2BasedMQTTAuthenticator"> <property name="hostURL">https://localhost:9447/services/OAuth2TokenValidationService</property> <property name="username">admin</property> <property name="password">admin</property> <property name="maxConnectionsPerHost">10</property> <property name="maxTotalConnections">150</property> </authenticator>

   2.  The port that refers to the IoT core profile in the tokenEndpoint attribute that is in the <org.wso2.carbon.andes.extensions.device.mgt.mqtt.authorization.DeviceAccessBasedMQTTAuthorize> class.
      Example:

      Code Block

      <authorizer class="org.wso2.carbon.andes.extensions.device.mgt.mqtt.authorization.DeviceAccessBasedMQTTAuthorizer"> <property name="username">admin</property> <property name="password">admin</property> <property name="tokenEndpoint">https://localhost:8247</property> <!--offset time from expiry time to trigger refresh call - seconds --> <property name="tokenRefreshTimeOffset">100</property> <property name="deviceMgtServerUrl">https://localhost:8247</property> </authorizer>

5. Configure following properties in the <IOTS_HOME>/conf/identity/sso-idp-config.xml file file.

   IoT core

   By default the core profile is offset by 0. In step 1, you offset the core profile by 4. Therefore, all the ports relevant to core needs to be offset by 4. Example: Code Block <AssertionConsumerServiceURL>https://localhost:9447/devicemgt/uuf/sso/acs</AssertionConsumerServiceURL> <DefaultAssertionConsumerServiceURL>https://localhost:9447/devicemgt/uuf/sso/acs</DefaultAssertionConsumerServiceURL> <Audience>https://localhost:9447/oauth2/token</Audience> <Recipient>https://localhost:9447/oauth2/token</Recipient> <AssertionConsumerServiceURL>https://localhost:9447/store/acs</AssertionConsumerServiceURL> <DefaultAssertionConsumerServiceURL>https://localhost:9447/store/acs</DefaultAssertionConsumerServiceURL> <AssertionConsumerServiceURL>https://localhost:9447/social/acs</AssertionConsumerServiceURL> <DefaultAssertionConsumerServiceURL>https://localhost:9447/social/acs</DefaultAssertionConsumerServiceURL> <AssertionConsumerServiceURL>https://localhost:9447/publisher/acs</AssertionConsumerServiceURL> <DefaultAssertionConsumerServiceURL>https://localhost:9447/publisher/acs</DefaultAssertionConsumerServiceURL> <AssertionConsumerServiceURL>https://localhost:9447/api-store/jagg/jaggery_acs.jag</AssertionConsumerServiceURL> <DefaultAssertionConsumerServiceURL>https://localhost:9447/api-store/jagg/jaggery_acs.jag</DefaultAssertionConsumerServiceURL> <AssertionConsumerServiceURL>https://localhost:9447/portal/acs</AssertionConsumerServiceURL> <DefaultAssertionConsumerServiceURL>https://localhost:9447/portal/acs</DefaultAssertionConsumerServiceURL> <Audience>https://localhost:9447/oauth2/token</Audience> <Recipient>https://localhost:9447/oauth2/token</Recipient> <Audience>https://localhost:9447/oauth2/token</Audience> <Recipient>https://localhost:9447/oauth2/token</Recipient>

   Analytics

   By default the analytics profile is offset by 2. In step 1, you offset the analytics profile by 3 more again. Therefore, all the ports relevant to the analytics profile needs to be offset by 3 more. Example: Code Block <AssertionConsumerServiceURL>https://localhost:9448/portal/acs</AssertionConsumerServiceURL> <DefaultAssertionConsumerServiceURL>https://localhost:9448/portal/acs</DefaultAssertionConsumerServiceURL>

6. Open the <IOTS_HOME>/repository/deployment/server/jaggeryapps/devicemgt/app/conf/app-conf.json file and configure the following properties related to the IoT Server's core profile:
   Example:
   By default, the core profile is offset by 0. In step 1, you offset the core profile by 4. Therefore, all the ports relevant to core needs to be offset by 4.

   Code Block
   "portalURL": "https://${server.ip}:9447",

7. Open the <IOTS_HOME>/repository/deployment/server/jaggeryapps/api-store/site/conf/site.json file and configure the following properties and configure the following properties related to the IoT Server's core profile:
   Example:
   By default, the core profile is offset by 0. In step 1, you offset the core profile by 4. Therefore, all the ports relevant to core needs to be offset by 4. 

   Code Block

   "identityProviderURL" : "https://localhost:9447/samlsso", "identityProviderURI" : "http://localhost:8084/openid-connect-server-webapp/", "authorizationEndpointURI" : "http://localhost:8084/openid-connect-server-webapp/authorize", "tokenEndpointURI" : "http://localhost:8084/openid-connect-server-webapp/token", "userInfoURI" : "http://localhost:8084/openid-connect-server-webapp/userinfo", "jwksURI" : "http://localhost:8084/openid-connect-server-webapp/jwk",

8. Open the <IOTS_HOME>/conf/etc/webapp-publisher-config.xml file, and set true as the value for <EnabledUpdateApi>.

   Code Block
   <!-- If it is true, the APIs of this instance will be updated when the webapps are redeployed --> <EnabledUpdateApi>true</EnabledUpdateApi>

   Info
   If you have not started WSO2 IoT Server previously, you don't need this configuration. When the server starts for the first time it will update the APIs and web apps with the new ports.

   Note

   Make sure to configure this property back to  to false if you need to restart the server again after the configuring the ports.  By enabling the update API property, the APIs and the respective web apps get updated when the server restarts. This takes some time. Therefore, if you need to restart the server many times after this configuration or when in a production environment, you need to revert back to the default setting.
