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
Step 5. Accessing GlassFish.
