Install WildFly on Ubuntu 22.04

In this tutorial, we will show you how to install WildFly on Ubuntu 22.04 LTS. For those of you who didn’t know, WildFly is a powerful, modular, and lightweight application server that helps you build amazing applications. It is cross-platform and comes with a sophisticated interface that makes changing application server settings and configuration very simple and quick. As of this writing, WildFly 26 is the latest release in a series of JBoss opensource application server offerings

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the WildFly (JBoss) on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.


  • A server running one of the following operating systems: Ubuntu 22.04, 20.04, and any other Debian-based distribution like Linux Mint.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install WildFly on Ubuntu 22.04 LTS Jammy Jellyfish

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade
sudo apt install wget apt-transport-https gnupg2 software-properties-common

Step 2. Installing Java.

WildFly requires a Java Standard Edition Runtime Environment (JRE) version 11 or later. Now run the following command to install OpenJDK:

sudo apt install default-jdk

Verify the installation:

java -version

Step 3. Installing WildFly on Ubuntu 22.04.

By default, WildFly is available on Ubuntu 22.04 base repository. Now run the following command below to download the latest stable version of WildFly to your Ubuntu system:

wget https://github.com/wildfly/wildfly/releases/download/26.1.1.Final/wildfly-26.1.1.Final.tar.gz

Next, extract the downloaded file:

tar -xf wildfly-26.1.1.Final.tar.gz

Move to /opt directory, so that we don’t accidentally delete it:

sudo mv wildfly-26.1.1.Fina /opt/wildlfy

Now change the directory permissions to the user and group WildFly:

sudo chown -RH wildfly:wildfly /opt/wildfly

Step 4. Add WildFly Users.

Create a user and group for WildFly:

sudo groupadd -r wildfly
sudo useradd -r -g wildfly -d /opt/wildfly -s /sbin/nologin wildfly

Step 5. Create WildFly Management Console and Application User.

We run a script to either configure the existing “admin” user or create a new one. Just execute the given command below:

sh /opt/wildfly/bin/add-user.sh

Step 6. Configure WildFly.

Now we create a WildFly directory which will store the configuration files in the /etc/ directory:

sudo mkdir -p /etc/wildfly

Copy WildFly systemd service, configuration file, and start scripts templates from the /opt/wildfly/docs/contrib/scripts/systemd/ directory:

sudo cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.conf /etc/wildfly/
sudo cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.service /etc/systemd/system/
sudo cp /opt/wildfly/docs/contrib/scripts/systemd/launch.sh /opt/wildfly/bin/

Then, make the scripts in the /opt/wildfly directory executable:

sudo chmod +x /opt/wildfly/bin/*.sh

Now start and enable the Wildfly service on your Ubuntu system:

sudo systemctl enable --now wildfly
sudo systemctl daemon-reload
sudo systemctl start wildfly

Step 7. Configure WildFly Admin Console.

By default, you won’t be able to access the Admin interface. Now run a script to configure the existing “administrator” user or create a new one:

sudo nano /etc/wildfly/wildfly.conf

Replace with in the following line:


Step 8. Configure the Firewall.

If your server is protected by a firewall and you want to access the WildFly interface from the outside of your local network you need to open ports 8080and 9990:

sudo ufw allow 8080/tcp
sudo ufw allow 9990/tcp

Step 9. Accessing WildFly Web Interface.

Once successfully installed, open your web browser and access the WildFly using the URL https://your-IP-address:8080. You will be redirected to the WildFly page:
