WildFly/JBoss is a Java Server used for the development of Java Projects and provides most of the features and being used by the Enterprises for its better performance & almost all features required. So mostly it is used by main Enterprises as compared to its competitors like Apache, Tomcat, Glassfish, Jetty. Other servers do not provides the all features needed but all of them provides most of the enterprise features. WildFly is the community edition & JBoss is the enterprise edition. JBoss is more secure but both are provided by Redhat Inc. So we recommend WildFly & we’re going to Install it on Our Ubuntu system today. So , follow the steps to proceed further.
First of all you must have installed Java.

java -version

Install WildFly 18 on Ubuntu 19.04

Download the WildFly 18 & choose the location to install it .

mkdir -p ~/sabi/servers
cd ~/sabi/servers
wget https://download.jboss.org/wildfly/18.0.1.Final/wildfly-18.0.1.Final.zip
unzip wildfly-18.0.1.Final.zip

Now add an admin to manage some sources (data sources).

cd wildfly-18.0.1.Final/bin/
./add-user.sh 

Fill the required details.

Now, start WildFly server instance in standalone as shown below:

$ ./standalone.sh
