问题
When I tried to deploy the keycloak-quickstart app-profile-jee-vanilla project, I ran into an error message. A bit of web searching did not provide a resolution, so I thought to ask here.
Here are the steps that I followed. Three bash shells are involved.
KEYCLOAK SHELL
curl -O -L https://downloads.jboss.org/keycloak/4.1.0.Final/keycloak-4.1.0.Final.tar.gz tar xvfz keycloak-4.1.0.Final.tar.gz ./keycloak-4.1.0.Final/bin/standalone.sh -Djboss.socket.binding.port-offset=100
WILDFLY SHELL
curl -O -L http://download.jboss.org/wildfly/11.0.0.Final/wildfly-11.0.0.Final.tar.gz curl -O -L https://downloads.jboss.org/keycloak/4.1.0.Final/adapters/keycloak-oidc/keycloak-wildfly-adapter-dist-4.1.0.Final.tar.gz tar xvfz wildfly-11.0.0.Final.tar.gz cd wildfly-11.0.0.Final tar xvfz ../keycloak-wildfly-adapter-dist-4.1.0.Final.tar.gz cd bin ./jboss-cli.sh --file=adapter-elytron-install-offline.cli cd ../.. ./wildfly-11.0.0.Final/bin/standlone.sh
QUICKSTART SHELL
git clone https://github.com/keycloak/keycloak-quickstarts cd keycloak-quickstarts/app-profile-jee-vanilla mvn clean wildfly:deploy
After a few minutes of compiling and such I see the "The required mechanism 'BASIC' is not available in mechanisms [KEYCLOAK] from the HttpAuthenticationFactory" message.
Can someone point me in the direction to resolve this issue?
回答1:
The problem, as I now see, is that the elytron adapter was installed and it should not have been. I removed the Wildfly directory. Then un-tarred the tgz file. Without doing any other configuration, I started the Wildfly server. After the server started, the wildfly:deploy maven command worked.
回答2:
you just need to configure the following file: standalone/configuration/standalone.xml
check the link bellow: https://www.keycloak.org/docs/latest/getting_started/index.html
step 4.5
before run:
sudo mvn clean wildfly:deploy
回答3:
according to the link below, this has to do with the deafult basic authentication setup in Wildfly, which is missing credentials by default (ldap-realm is insufficiently configured) https://issues.jboss.org/browse/JBEAP-9943
the issue can be resolved by redirecting authentication to Keycloak for a specific Wildfly deployment such as "vanilla.war", as described here: https://github.com/keycloak/keycloak-quickstarts/blob/latest/app-profile-jee-vanilla/README.md#configure-client-adapter-subsystem
and then deploying the app as posted in the issue (mvn clean wildfly:deploy)
回答4:
Found out that the order of the "Getting Started Guide" of Keycloak needs to be changed. You have to do the step where you change the standalone.xml file afterwards.
Do this step before: Start the WildFly server and complete these steps:
> git clone https://github.com/keycloak/keycloak-quickstarts
> cd keycloak-quickstarts/app-profile-jee-vanilla
> mvn clean wildfly:deploy
and then change the "standalone.xml" file with:
> cd bin
> jboss-cli.bat --file=adapter-elytron-install-offline.cli

I got the same problem. I found the workaround.
Before running mvn clean wildfly:deploy, I set the secure-deployment in a keycloak subsystem as following:
<subsystem xmlns="urn:jboss:domain:keycloak:1.1">
<secure-deployment name="vanilla.war">
<realm>demo</realm>
<auth-server-url>http://localhost:8180/auth</auth-server-url>
<public-client>true</public-client>
<ssl-required>EXTERNAL</ssl-required>
<resource>vanilla</resource>
</secure-deployment>
</subsystem>
