Getting Started Guide

In " standalone " mode each WildFly 23 server instance is an independent process (similar to previous JBoss AS versions; e.g., 3, 4, 5, or 6). The configuration files, deployment content and writable areas used by the single standalone server run from a WildFly installation are found in the following subdirectories under the top level "standalone" directory:

A key feature of WildFly 23 is the managing multiple servers from a single control point. A collection of multiple servers are referred to as a " domain ". Domains can span multiple physical (or virtual) machines with all WildFly instances on a given host under the control of a Host Controller process. The Host Controllers interact with the Domain Controller to control the lifecycle of the WildFly instances running on that host and to assist the Domain Controller in managing them. The configuration files, deployment content and writeable areas used by domain mode processes run from a WildFly installation are found in the following subdirectories under the top level "domain" directory:

Important to note is that the domain and standalone modes determine how the servers are managed not what capabilities they provide.

After executing one of the above commands, you should see output similar to what’s shown below.

As with previous WildFly releases, you can point your browser to http://localhost:8080 (if using the default configured http port) which brings you to the Welcome Screen:

From here you can access links to the WildFly community documentation set, stay up-to-date on the latest project information, have a discussion in the user forum and access the enhanced web-based Administration Console. Or, if you uncover a defect while using WildFly, report an issue to inform us (attached patches will be reviewed). This landing page is recommended for convenient access to information about WildFly 23 but can easily be replaced with your own if desired.

By default WildFly 23 is now distributed with security enabled for the management interfaces, this means that before you connect using the administration console or remotely using the CLI you will need to add a new user, this can be achieved simply by using the add-user.sh script in the bin folder.

After starting the script you will be guided through the process to add a new user: -

In this case a new user is being added for the purpose of managing the servers so select option a.

You will then be prompted to enter the details of the new user being added: -

It is important to leave the name of the realm as 'ManagementRealm' as this needs to match the name used in the server’s configuration, for the remaining fields enter the new username, password and password confirmation.

Provided there are no errors in the values entered you will then be asked to confirm that you want to add the user, the user will be written to the properties files used for authentication and a confirmation message will be displayed.

The modified time of the properties files are inspected at the time of authentication and the files reloaded if they have changed, for this reason you do not need to re-start the server after adding a new user.

To access the web-based Administration Console, simply follow the link from the Welcome Screen. To directly access the Management Console, point your browser at:

http://localhost:9990/console

If you modify the management-http socket binding in your running configuration: adjust the above command accordingly. If such modifications are made, then the link from the Welcome Screen will also be inaccessible.

If you have not yet added at least one management user an error page will be displayed asking you to add a new user, after a user has been added you can click on the 'Try Again' link at the bottom of the error page to try connecting to the administration console again.

If you prefer to manage your server from the command line (or batching), the jboss-cli.sh script provides the same capabilities available via the web-based UI. This script is accessed from $JBOSS_HOME/bin directory; e.g.,

Notice if no host or port information provided, it will default to localhost:9990.

When running locally to the WildFly process the CLI will silently authenticate against the server by exchanging tokens on the file system, the purpose of this exchange is to verify that the client does have access to the local file system. If the CLI is connecting to a remote WildFly installation then you will be prompted to enter the username and password of a user already added to the realm.

Once connected you can add, modify, remove resources and deploy or undeploy applications. For a complete list of commands and command syntax, type help once connected.

WildFly logging can be configured with the web console or the command line interface. You can get more detail on the Logging Configuration page.

Turn on debugging for a specific category with CLI:

By default the server.log is configured to include all levels in it’s log output. In the above example we changed the console to also display debug messages.
