Install Java JDK on Ubuntu

WildFly is written in Java and needs to be installed as a prerequisite. There are two options for installing Java on Ubuntu Linux system.

Install OpenJDK.

Install the Java SE Development Kit.

The simplest way to get Java is to install OpenJDK on your Ubuntu system by running the commands below.

sudo apt update

sudo apt -y install default-jdk

The default version of Java installed from the above command is Java 10+. This is supported by WildFly.

$java -version

openjdk 11.0.13 2021-10-19

OpenJDK Runtime Environment (build 11.0.13 + 8-Ubuntu-0ubuntu1)

64-bit OpenJDK VM Server (build 11.0.13 + 8-Ubuntu-0ubuntu1, mixed mode, sharing)

Download the WildFly installation file

Check the WildFly downloads page for the latest releases before downloading the file. Here we will download WildFly 18.0.1.Final.

export WILDFLY_RELEASE = “26.0.0 ″ wget

https://github.com/wildfly/wildfly/releases/download/${WILDFLY_RELEASE}.Final/wildfly -${WILDFLY_RELEASE}.Final.tar.gz

Once the file is downloaded, extract it.

tar xvf wildfly – ${WILDFLY_RELEASE}.Final.tar.gz

Move the resulting folder to /opt/wildfly.

sudo mv wildfly – ${WILDFLY_RELEASE}.Final / opt / wildfly

Configure Systemd for WildFly

Let’s now create a system user and group that will run the WildFly service.

sudo groupadd –system wildfly

sudo useradd -s / sbin / nologin –system -d / opt / wildfly -g wildfly wildfly

Create the WildFly settings directory.

Copy the systemd WildFly service, configuration file, and startup script templates from the / opt / wildfly / docs / contrib / scripts / systemd / directory.

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

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

sudo cp /opt/wildfly/docs/contrib/scripts/systemd/launch.sh / opt / wildfly / bin /

sudo chmod + x /opt/wildfly/bin/launch.sh

Set permissions / opt / wildfly.

sudo chown -R wildfly: wildfly / opt / wildfly

Reload the systemd service.

sudo systemctl daemon-reload

Start and enable the WildFly service:

sudo systemctl start wildfly

sudo systemctl enable wildfly

Confirm the status of WildFly Application Server.

sudo systemctl status wildfly

The service must be bound to port 8080.

$ss -tunelp | grep 8080

tcp LISTEN 0 128 0.0.0.0:8080 0.0.0.0:* users: ((“java”, pid = 6854, fd = 389)) uid: 999 ino: 30339 sk: 3

Add WildFly users

By default, WildFly 16 is now shipped with security enabled for management interfaces. We need to create a user who can access the WildFly admin console or remotely use the CLI. A script is provided to manage users. Run it by running the command:

sudo /opt/wildfly/bin/add-user.sh

You will be asked to choose the type of user to be added. Since this is the first user, we want to make it an administrator. So choose one. What type of user do you want to add?

a) Management User (mgmt-users.properties)

b) Application user (application-users.properties)

(one):

Provide the desired username for the user.

Enter the details of the new user to be added.

Using the ‘ManagementRealm’ realm as discovered in existing property files.

Username :

Set the password for the user:

Password recommendations are listed below. To modify these restrictions, edit the add-user.properties configuration file.

The password must be different from the username.

The password must not be one of the following restricted values ​​{root, admin, administrator}

The password must contain at least 8 characters, 1 alphabetic character(s), 1 digit(s), 1 non-alphanumeric symbol(s)

Password:

Type the password again:

Accessing the WildFly Admin Console

To be able to run WildFly scripts in your current shell session, add / opt / wildfly / bin / to your $ PATH.

cat >> ~ / .bashrc

export WildFly_BIN = ”/ opt / wildfly / bin /”

export PATH = $ PATH: $ WildFly_BIN
