A Step-by-Step Guide to WildFly Standalone Configuration
If you're looking to configure WildFly in standalone mode, this guide will help you get started. WildFly is a powerful open-source application server that allows you to build and deploy Java EE applications. Here's how to set it up in standalone mode.
Step 1: Download WildFly
The first step is to download WildFly from the official website. You can choose between the latest stable version or a specific version that suits your needs. Once downloaded, extract the files to a directory of your choice.
Step 2: Start WildFly
To start WildFly, navigate to the bin directory and run the standalone.sh or standalone.bat file, depending on your operating system. This will start the server in standalone mode and you will see output similar to the following:

Step 3: Access the Management Console
Once WildFly is up and running, you can access the management console by opening a web browser and navigating to http://localhost:9990/console. This will open the management console login page where you can enter the default username and password: admin/admin.
Step 4: Configure WildFly
To configure WildFly, you can use the management console or the command-line interface (CLI). Here's an example of how to use the CLI to configure a new data source:
Open a terminal window and navigate to the bin directory.
Run the jboss-cli.sh or jboss-cli.bat file, depending on your operating system.
Connect to the running WildFly instance by entering the following command:
connect
Create a new data source by entering the following command:
/subsystem=datasources/data-source=MyDS:add(driver-name=h2, jndi-name=java:jboss/datasources/MyDS, connection-url=jdbc:h2:mem:test;DB_CLOSE_DELAY=-1, user-name=sa, password=sa)
This will create a new data source named "MyDS" that uses the H2 database driver.
Step 5: Deploy an Application
To deploy an application to WildFly, you can use the management console or the CLI. Here's an example of how to deploy a WAR file using the CLI:
Open a terminal window and navigate to the bin directory.
Run the jboss-cli.sh or jboss-cli.bat file, depending on your operating system.
Connect to the running WildFly instance by entering the following command:
connect
Deploy the WAR file by entering the following command:
deploy /path/to/your/application.war
This will deploy your application to WildFly.
Summary:
Configuring WildFly in standalone mode is relatively straightforward, but it can be daunting if you're new to the platform. By following the steps outlined in this article, you should be able to get up and running with WildFly in no time.
Remember to consult the official WildFly documentation if you need further assistance or have specific questions about your configuration. Happy coding!
