WFLYCTL0083: failed to load module org,keycloak.keycloak-server-subsytem

Question

When I am starting my Wildfly server I am getting this error which ultimately shuts my server from running. What am I missing while installing the server ?

Answer 1

Adding little more information to what Haseb Ansari has provided already. Basically, here are the steps that needs to be performed to get keycloak setup in wildfly.

Assumption: Wildfly is extracted to ${user.home}/apps/wildfly, lets call it ${jboss.home} here.

Following are the steps that needs to be done.

1. Download OpenID connect adapter from keycloak

2. Extract keycloak-wildfly-adapter-dist-3.3.0.CR2.zip

$> cd ~/Downloads

$>unzip ./keycloak-wildfly-adapter-dist-3.3.0.CR2.zip -d keycloak-wildfly-adapter

3. copy files to ${jboss.home}

cd keycloak-wildfly-adapter/bin

cp ./adapter-* ${jboss.home}

cp -rf ./modules ${jboss.home}

4. Execute jboss cli

cd ${jboss.home}

$>./bin/jboss-cli.sh --file=adapter-elytron-install-offline.cli

You get a message as below [copied from terminal]

$> wildfly]$./bin/jboss-cli.sh --file=adapter-elytron-install-offline.cli
{
    "outcome" => "success",
    "result" => [("keycloak" => "1.1.0")]
}
{"outcome" => "success"}
{"outcome" => "success"}
{"outcome" => "success"}
{"outcome" => "success"}
{"outcome" => "success"}
{"outcome" => "success"}
{"outcome" => "success"}
{"outcome" => "success"}

You may use ../bin/jboss-cli.sh --file=adapter-install-offline.cli if your wildfly version is 10.

5. Run jboss

./bin/standalone.sh

Answer 2

The same error occurred with me.

The solution was copying the keycloak module to the folder below:

{your_jboss_folder}/modules/system/add-ons/keycloak/

I had it running on another server, so it was simply copy and paste. If you don't have it, try searching these modules on keycloak website.

Hope it helps.
