Configure HTTPS for Keycloak on RHEL 6.6

###Make the Keystore accessible for Keycloak

gocedar
cd CEDAR_CA
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 content 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 and add a HTTPS listener to the default HTTP listener as follows:

<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

Stop the server if it is running and restart it as follows:

gokk
./standalone.sh

At this moment you don't have the root certificate in your trust store, so accessing Keycloak from a browser on port 8543 as follows should alert you about an invalid certificate:

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

Do not add a security exception at this moment.

However, you can test it from the lynx browser, if you have it. If not, you can install it:

yum install lynx

And then test it:

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

Lynx will alert you about the invalid SSL certificate. You can accept that and continue. The important thing is not to add the security exception to your default browser.
