Configure HTTPS for Keycloak on RHEL 6.6

###Make keystore accessible for Keycloak

cp keycloak.jks $KEYCLOAK_HOME/standalone/configuration/

###Modify Keycloak configuration

cd $KEYCLOAK_HOME/standalone/configuration/
vi standalone.xml

Locate the <security-realms> element, and add the below to that block

Note: make sure to replace secret with the actual password!

<security-realm name="UndertowRealm">
  <server-identities>
    <ssl>
      <keystore path="keycloak.jks" relative-to="jboss.server.config.dir" keystore-password="secret" />
    </ssl>
  </server-identities>
</security-realm>

Locate the <server name="default-server"> element, add this line below the default http listener

<https-listener name="https" socket-binding="https" security-realm="UndertowRealm"/>

Locate the <socket-binding-group element. You probably will need to modify the already existing https port. Change the line to the following:

<socket-binding name="https" port="${jboss.https.port:8543}"/>

###Verify the configuration

Start the server

gokk
./bin/standalone.sh

You will not be able to test the https port of keycloak from a browser at this moment, so please test it from the command line on the server:

lynx https://auth.metadatacenter.net:8543/
