This guide helps you get started with Keycloak. It covers server configuration and use of the default database. Advanced deployment options are not covered. For a deeper description of features or configuration options, consult the other reference guides.
This section describes how to boot a Keycloak server in standalone mode, set up the initial admin user, and log in to the Keycloak admin console.
Download the Keycloak Server:
|This file can be downloaded from Keycloak downloads.|
The keycloak-9.0.3.[zip|tar.gz] file is the server-only distribution. It contains only the scripts and binaries to run the Keycloak server.
Place the file in a directory you choose and use either the
tar utility to extract it.
$ unzip keycloak-9.0.3.zip or $ tar -xvzf keycloak-9.0.3.tar.gz
> unzip keycloak-9.0.3.zip
To boot the Keycloak server, go to the
bin directory of the server distribution and run the
standalone boot script:
$ cd bin $ ./standalone.sh
After the server boots, open http://localhost:8080/auth in your web browser. The welcome page will indicate that the server is running.
Enter a username and password to create an initial admin user.
This account will be permitted to log in to the
master realm’s administration console, from which you will create realms and users and register applications to be secured by Keycloak.
You can only create an initial admin user on the Welcome Page if you connect using
After you create the initial admin account, use the following steps to log in to the admin console:
Click the Administration Console link on the Welcome page or go directly to the console URL http://localhost:8080/auth/admin/
Type the username and password you created on the Welcome page to open the Keycloak Admin Console.Admin Console
In this section you will create a new realm within the Keycloak admin console and add a new user to that realm. You will use that new user to log in to your new realm and visit the built-in user account service that all users have access to.
Before you can create your first realm, complete the installation of Keycloak and create the initial admin user as shown in Installing and Booting.
To create a new realm, complete the following steps:
From the Master drop-down menu, click Add Realm. When you are logged in to the master realm this drop-down menu lists all existing realms.
demoin the Name field and click Create.
When the realm is created, the main admin console page opens. Notice the current realm is now set to
demo. Switch between managing the
master realm and the realm you just created by clicking entries in the Select realm drop-down menu.
To create a new user in the
demo realm, along with a temporary password for that new user, complete the following steps:
From the menu, click Users to open the user list page.
On the right side of the empty user list, click Add User to open the add user page.
Enter a name in the
Usernamefield; this is the only required field. Flip the Email Verified switch from Off to On and click Save to save the data and open the management page for the new user.
Click the Credentials tab to set a temporary password for the new user.
Type a new password and confirm it. Click Reset Password to set the user password to the new one you specified.
|This password is temporary and the user will be required to change it after the first login. To create a password that is persistent, flip the Temporary switch from On to Off before clicking Reset Password.|
After you create the new user, log out of the management console by opening the user drop-down menu and selecting Sign Out.
Go to http://localhost:8080/auth/realms/demo/account and log in to the User Account Service of your
demorealm with the user you just created.
Type the username and password you created. You will be required to create a permanent password after you successfully log in, unless you changed the Temporary setting to Off when you created the password.
The user account service page will open. Every user in a realm has access to this account service by default. From this page, you can update profile information and change or add additional credentials. For more information on this service see the Server Administration Guide.
This section describes how to secure a Java servlet application on the WildFly application server by:
Installing the Keycloak client adapter on a WildFly application server distribution
Creating and registering a client application in the Keycloak admin console
Configuring the application to be secured by Keycloak
Before you can secure a Java servlet application, you must complete the installation of Keycloak and create the initial admin user as shown in Installing and Booting.
There is one caveat: Even though WildFly is bundled with Keycloak, you cannot use this as an application container. Instead, you must run a separate WildFly instance on the same machine as the Keycloak server to run your Java servlet application. Run the Keycloak using a different port than the WildFly, to avoid port conflicts.
To adjust the port used, change the value of the
jboss.socket.binding.port-offset system property when starting the server from the command line. The value of this property is a number that will be added to the base value of every port opened by the Keycloak server.
To start the Keycloak server while also adjusting the port:
$ cd bin $ ./standalone.sh -Djboss.socket.binding.port-offset=100
> ...\bin\standalone.bat -Djboss.socket.binding.port-offset=100
After starting Keycloak, go to http://localhost:8180/auth/admin/ to access the admin console.
Download the WildFly distribution and extract it from the compressed file into a directory on your machine.
Download the WildFly OpenID Connect adapter distribution from keycloak.org.
Extract the contents of this file into the root directory of your WildFly distribution.
Run the appropriate script for your platform:
$ cd bin $ ./jboss-cli.sh --file=adapter-install-offline.cli
> cd bin > jboss-cli.bat --file=adapter-install-offline.cli
$ cd bin $ ./jboss-cli.sh --file=adapter-elytron-install-offline.cli
> cd bin > jboss-cli.bat --file=adapter-elytron-install-offline.cli
This script will make the necessary edits to the
Start the application server.
$ cd bin $ ./standalone.sh
To configure the WildFly instance that the application is deployed on so that this app is secured by Keycloak, complete the following steps.
standalone/configuration/standalone.xmlfile in the WildFly instance that the application is deployed on and search for the following text:
Modify this text to prepare the file for pasting in contents from the Keycloak OIDC JBoss Subsystem XML template we obtained Keycloak admin console Installation tab by changing the XML entry from self-closing to using a pair of opening and closing tags:
<subsystem xmlns="urn:jboss:domain:keycloak:1.1"> </subsystem>
Paste the contents of the template within the
<subsystem>element, as shown in this example:
<subsystem xmlns="urn:jboss:domain:keycloak:1.1"> <secure-deployment name="WAR MODULE NAME.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>
<subsystem xmlns="urn:jboss:domain:keycloak:1.1"> <secure-deployment name="vanilla.war"> ... </subsystem>
Reboot the application server.
You must have the following installed on your machine and available in your PATH before you continue:
Java JDK 8
Apache Maven 3.1.1 or higher
|You can obtain the code by cloning the Keycloak Quickstarts Repository repository at https://github.com/keycloak/keycloak-quickstarts. The quickstarts are designed to work with the most recent Keycloak release.|
Make sure your WildFly application server is started before you continue.
To download, build, and deploy the code, complete the following steps.
$ git clone https://github.com/keycloak/keycloak-quickstarts $ cd keycloak-quickstarts/app-profile-jee-vanilla $ mvn clean wildfly:deploy
During installation, you will see some text scroll by in the application server console window.
To confirm that the application is successfully deployed, go to http://localhost:8180/vanilla and a login page should appear.
If you click Login, the browser will pop up a BASIC auth login dialog. However, the application is not yet secured by any identity provider, so anything you enter in the dialog box will result in a
To define and register the client in the Keycloak admin console, complete the following steps:
