In this tutorial we will show you how to install WildFly on CentOS 8. 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 (JBoss) on a CentOS 8 server.
Install WildFly on CentOS 8
Step 1. First let’s start by ensuring your system is up-to-date.
sudo dnf update
Step 2. Installing Java OpenJDK.
Install the OpenJDK package by running:
sudo dnf install java-11-openjdk-devel
Step 3. Create a User WildFly.
Running WildFly as the root user is a security risk and not considered best practice. To create a new system user and group named wildfly with home directory
sudo groupadd -r wildfly sudo useradd -r -g wildfly -d /opt/wildfly -s /sbin/nologin wildfly
Step 4. Install WildFly on CentOS 8.
First, Download the latest version of WildFly on the server and extract it using the following commands:
WILDFLY_VERSION=18.0.1.Final wget https://download.jboss.org/wildfly/$WILDFLY_VERSION/wildfly-$WILDFLY_VERSION.tar.gz -P /tmp
Once the download is completed, extract the tar.gz file and move it to the /opt directory:
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 for WildFly.
First, creating a directory which will hold the WildFly configuration file:
sudo mkdir -p /etc/wildfly
Next, copy the configuration file to the /etc/wildfly directory:
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:
# 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.
Use the following commands to open the necessary port:
sudo firewall-cmd --zone=public --permanent --add-port=8080/tcp sudo firewall-cmd --reload
Step 7. Accessing WildFly Installation.
WildFly will be available on HTTP port 8080 by default. Open your favorite browser and navigate to http://your-domain.com:8080 or http://your-server-ip:8080 and complete the required the steps to finish the installation.
