Installing WildFly on CentOS 7

WildFly is a popular and open-source Java application server, formerly known as JBoss AS. It is a lightweight and flexible server that supports Java EE (Enterprise Edition) applications. In this tutorial, we will walk you through the steps of installing WildFly on CentOS 7.

Prerequisites

• A CentOS 7 server with root access.
• Java Development Kit (JDK) installed on your CentOS server. You can install OpenJDK or Oracle JDK.

Step 1: Update System Packages

Before installing any packages, it is recommended to update the system packages to the latest version. Run the following commands:

sudo yum update sudo yum upgrade

Step 2: Install Java Development Kit (JDK)

WildFly requires a Java Development Kit to run. If you have not already installed one, you can follow these instructions to install OpenJDK:

sudo yum install java-1.8.0-openjdk-devel

Step 3: Download and Extract WildFly

Now we need to download and extract the WildFly server on our CentOS machine. You can download the latest version of WildFly from the official website or use the following command to download it:

curl -O https://download.jboss.org/wildfly/{version}/wildfly-{version}.tar.gz

The {version} placeholder should be replaced with the desired WildFly version number. After the download is complete, extract the tar.gz file using the following command:

tar xzf wildfly-{version}.tar.gz

Create a symbolic link to make it easier to access WildFly:

ln -s wildfly-{version} wildfly

Step 4: Start WildFly Server

To start the WildFly server, run the following command:

./wildfly/bin/standalone.sh

The server will start and listen on port 8080 by default. You can access the WildFly management console and applications by navigating to http://localhost:8080 in your web browser.

For customization or production deployment, you may want to configure WildFly further. The configuration files are located in the wildfly/standalone/configuration/ directory.

Step 5: Stop WildFly Server

To stop the WildFly server, press Ctrl + C in the terminal where the server is running.

Conclusion

You have successfully installed WildFly on CentOS 7. WildFly is now ready for development and deployment of Java EE applications. Enjoy exploring its features and functionality!
