Install WildFly on Ubuntu 18.04 LTS

In this tutorial, we will show you how to install WildFly on your Ubuntu 18.04 LTS. For those of you who didn’t know, The WildFly implements the Java Enterprise Edition (Java EE). It is among the most common source Java server applications. It offers you an administration dashboard to manage single or multiple domains efficiently.

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 through the step-by-step installation WildFly on a Ubuntu 18.04 (Bionic Beaver) server.

Install WildFly on Ubuntu 18.04 LTS Bionic Beaver

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

sudo apt update
sudo apt upgrade

Step 2. Download and install Java.

In order to run WildFly, Java has to be installed on the server so run the following command to install the Java Development Kit package (JDK):

sudo apt install default-jdk

Step 3. Create a WildFly User.

We will create a new system user and group named wildfly with a home directory /opt/wildfly that will run the WildFly service:

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

Step 4. Installing WildFly on Ubuntu.

First, Download the latest version of WildFly on the server and extract it using the following commands:

wget https://download.jboss.org/wildfly/$WILDFLY_VERSION/wildfly-$WILDFLY_VERSION.tar.gz -P /tmp
sudo tar xf /tmp/wildfly-$WILDFLY_VERSION.tar.gz -C /opt/

Next, create a symbolic link wildfly which will point to the WildFly installation directory:

sudo ln -s /opt/wildfly-$WILDFLY_VERSION /opt/wildfly
sudo chown -RH wildfly: /opt/wildfly

Step 5. Configure Systemd WildFly.

Start by creating a directory that will hold the WildFly configuration file:

sudo mkdir -p /etc/wildfly
sudo cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.conf /etc/wildfly/

By default, WildFly will run in a standalone mode and will listen on all interfaces. You can edit the file according to your needs:

nano /etc/wildfly/wildfly.conf
# The configuration you want to run
WILDFLY_CONFIG=standalone.xml

# The mode you want to run
WILDFLY_MODE=standalone

# The address to bind to
WILDFLY_BIND=0.0.0.0

Next copy the WildFly launch.sh script to the /opt/wildfly/bin/ directory:

sudo cp /opt/wildfly/docs/contrib/scripts/systemd/launch.sh /opt/wildfly/bin/
sudo sh -c 'chmod +x /opt/wildfly/bin/*.sh'
sudo cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.service /etc/systemd/system/

Then, start the WildFly service by executing:

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

Step 6. Configure the Firewall for WildFly.

Allow traffic on port 8080 type the following command:

sudo ufw allow 8080/tcp

Step 7. Accessing WildFly Installation.

WildFly will be available on HTTP port 8080 by default. Open your favorite browser and navigate to http://yourdomain.com:8080 or http://server-ip:8080 and complete the required steps to finish the installation.
