In this article, we will have explained the necessary steps to install and configure GlassFish on Ubuntu 20.04 LTS. Before continuing with this tutorial, make sure you are logged in as a user with sudo privileges. All the commands in this tutorial should be run as a non-root user.

GlassFish is a fully-fledged open-source reference implementation of Java EE application server for developing and deploying Java-based applications. It supports JPA, JSF, JSP/Servlet, JMS, RMI, as well as many other Java-based technologies. It also provides both web and CLI-based administration consoles for easier configuration and management of your Java applications and their respective components.

Install GlassFish on Ubuntu 20.04

Step 1. First, before you start installing any package on your Ubuntu server, we always recommend making sure that all system packages are updated.

sudo apt update
sudo apt upgrade

Step 2. Install Java.

GlassFish is powered by Java, it must be installed and configured on your Ubuntu server first. Run the following commands to install the OpenJDK 8 JDK package:

sudo apt install openjdk-8-jdk

Verify the installation:

java -version

Now we need to append the Java location to our environment file. Modify the path accordingly based on your Java path:

nano /etc/environment
JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64"

For changes to take effect on your current shell you can either log out and log in or run the following source command:

source /etc/environment

Finally, steps, verify that the JAVA_HOME environment variable was correctly set:

echo $JAVA_HOME

Result:

/usr/lib/jvm/java-8-openjdk-amd64

Step 3. Install GlassFish on the Ubuntu system.

Now download the latest nightly build version of GlassFish from their official GlassFish website:

wget http://download.oracle.com/glassfish/5.0.1/nightly/latest-glassfish.zip

Next, extract the files to the current directory:

sudo unzip latest-glassfish.zip

Step 4. Setting Up GlassFish Service.

Now create systemd for GlassFish:

sudo nano /etc/systemd/system/glassfish.service

Add the following lines:

[Unit]
Description = GlassFish Server v5.0
After = syslog.target network.target

[Service]
ExecStart=/opt/glassfish5/bin/asadmin start-domain
ExecReload=/opt/glassfish5/bin/asadmin restart-domain
ExecStop=/opt/glassfish5/bin/asadmin stop-domain
Type = forking

[Install]
WantedBy = multi-user.target

Save and exit. Now we need to reload system services:

sudo systemctl daemon-reload
sudo systemctl enable glassfish
sudo systemctl start glassfish
