Installation Guide for WildFly on Ubuntu 18.04 LTS
Requirements
- An Ubuntu 18.04 server environment.
- A non-root user with sudo access.
- A static IP address configured on your server (e.g., 192.168.0.235).
Step 1: Install Java
Since WildFly is written in Java, an installation of Java is required. Execute the following command to install Java:
sudo apt-get install default-jdk -y
After Java is installed, verify the installation by checking the version:
java -version
Sample Output:
openjdk version "10.0.2" 2018-07-17 OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.2) OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.2, mixed mode)
Step 2: Install WildFly
Download the latest version of WildFly from the official website using the following command:
wget http://download.jboss.org/wildfly/14.0.1.Final/wildfly-14.0.1.Final.tar.gz
After completing the download, extract the archive with:
cd /opt tar -xvzf wildfly-14.0.1.Final.tar.gz sudo mv wildfly-14.0.1.Final wildfly
By default, WildFly is bound to 127.0.0.1. To allow access from anywhere on your LAN, change the bind address to your server’s IP address by editing the standalone.xml file:
sudo nano /opt/wildfly/standalone/configuration/standalone.xml
Modify the specified lines:
<subsystem xmlns="urn:jboss:domain:webservices:2.0">
<wsdl-host>${jboss.bind.address:192.168.0.235}</wsdl-host>
<endpoint-config name="Standard-Endpoint-Config"/>
<interface name="management">
<inet-address value="${jboss.bind.address.management:192.168.0.235}"/>
</interface>
<interface name="public">
<inet-address value="${jboss.bind.address:192.168.0.235}"/>
</interface>
Save and close the file. Next, add a user for the management console using the script:
sudo /opt/wildfly/bin/add-user.sh
Fill in the following prompts as required:
What type of user do you wish to add?
a) Management User (mgmt-users.properties)

e.g. for a slave host controller connecting to the master or for a Remoting connection for server to server EJB calls.
yes/no? yes
To represent the user add the following to the server-identities definition
