For more about WildFly and other related documentation, please visit its homepageWhen you’re ready to setup WildFly on Ubuntu, follow the steps below:

Step 1: Install OpenJDK

WildFly is written in Java and require Java JDK to function… you either install the official Oracle Java JDK or use the open source alternative called OpenJDK…

For this tutorial, we’re going to be installing the open source version of Java..

To do that, run the commands below:

sudo apt update
sudo apt install default-jdk

After installing OpenJDK above, you can run the commands below to validate that it is installed…

java -version

You should see similar lines as below:

openjdk version "10.0.2" 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4)
OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4, mixed mode)

If you see the lines above, then Java is installed and ready…

Step 2: Setup WildFly User

Since this is an application server, it’s usually recommended to use a dedicated service account… Run the commands below to create WildFly service account to manage the server..

Run the commands below to create an account and group called wildfly…

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

After that, continue below to downloading and configuring WildFly packages…

Step 3: Download and Configure WildFly

Now that you’ve installed Java JDK and created a service account for WildFly, run the commands below to download WildFly packages… At the time of this post, the current version is 16.0.0.Final

You can check its download page to get the latest when they become available…

Using wget command, you can easily download it using the commands below:

cd /tmp

After downloading, run the commands below to create WildFly folder in the /opt directory and change its ownership to WildFly service account…

tar xvf wildfly-16.0.0.Final.tar.gz
sudo mv wildfly-16.0.0.Final/ /opt/wildfly
sudo chown -RH wildfly: /opt/wildfly

Next, create WildFly service folder in the /etc/ directory by running the commands below..

sudo mkdir -p /etc/wildfly

Then copy WildFly configuration files, executables into the newly created directory above, and make its scripts in the /etc/wildfly/bin directory executable…

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

After that copy its systemd file to the /etc/systemd/system/ directory by running the commands below

sudo cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.service /etc/systemd/system/

Now you can use the commands below to stop, start and enable WildFly services to automatically start at boot time…

sudo systemctl stop wildfly.service
