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.
GlassFish is being maintained and developed through the GlassFish Project. It is licensed under the Common Development and Distribution License (CDDL) as well as the GNU General Public License (GPL). The project is currently sponsored by Oracle.
In this article, we will show you how to install GlassFish on a Linux VPS with Ubuntu 18.04 OS.
Table of Contents
Make sure that your server meets the following minimum requirements:
- A VPS with Ubuntu 18.04 running on it (preferably a fresh installation)
- A user account with root access, or access to the “root” user
Install Updates and Fix Dependencies
Log in to your server via SSH:
Remember to replace “username” with the username which you wish to use on the server, as well as replacing “server_ip” with your server’s IP address.
Before starting with the GlassFish Server installation, it is a good idea to update the system packages to their latest versions, if any are available:
sudo apt-get update sudo apt-get upgrade
Install software package dependencies needed by GlassFish by running the following command:
sudo apt-get install software-properties-common wget unzip
Installing and Configuring Java 8
Since GlassFish is powered by Java, it must be installed and configured on your Ubuntu server first. As of writing, GlassFish 5.0 only supports Java 8.
This command will install Oracle JDK 8 using the PPA repository:
sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java8-installer
After the installation, you can check the active Java version using this command:
sudo java -version
You should see the following message:
java version "1.8.0_191" Java(TM) SE Runtime Environment (build 1.8.0_191-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)
Updating the Java Environment Variable
Most Java applications use the variable
JAVA_HOME in determining the location of your Java installation.
To check if you already have
JAVA_HOME set, type the following command:
If you see a blank line, it means there is no configured
JAVA_HOME variable. If there is, you can double check if it is using the correct path by following these next steps.
To determine the current Java location, use the following command:
sudo update-alternatives --config java
The output should show you the Java installation path, like the following:
Now we need to append the Java location to our environment file. Modify the path accordingly based on your Java path:
sudo echo JAVA_HOME=\"/usr/lib/jvm/java-8-oracle/bin/java\" >> /etc/environment
After that, we will need to source the file to update our shell:
Now you can verify if
JAVA_HOME is set by using either of the following commands:
echo $JAVA_HOME $JAVA_HOME -version
Installing the Latest GlassFish Server
At the time of writing, the current latest version of GlassFish Server is 5.0.1.
First, we need to change our current directory to /opt:
We can now download the latest nightly build version of GlassFish from their official GlassFish website.
sudo wget http://download.oracle.com/glassfish/5.0.1/nightly/latest-glassfish.zip
Extract the files to the current directory. You can choose a different directory if you wish to keep your installation of GlassFish elsewhere.
sudo unzip latest-glassfish.zip
To extract to a specific directory:
sudo unzip latest-glassfish.zip -d /path/to/desired/directory
Setting Up GlassFish Service
Create the service file:
sudo nano /etc/systemd/system/glassfish.service
Copy and paste the following. Modify the GlassFish path in respect to the directory of your GlassFish install:
Description = GlassFish Server v5.0
After = syslog.target network.target
Type = forking
WantedBy = multi-user.target
Save and exit. Now we need to reload system services:
sudo systemctl daemon-reload
Managing the GlassFish Service
To enable GlassFish at boot:
sudo systemctl enable glassfish
To start GlassFish:
sudo systemctl start glassfish
Check the service status using this command:
sudo systemctl status glassfish
Once GlassFish has started, you can now access the default page on port 8080.
You can access the web administrator console on port 4848.
Remember to replace “server-ip-address” with your server’s IP address.
Setting Up the GlassFish Path
GlassFish has a utility called
asadmin which accepts commands for setting up GlassFish via a command line. To run the
asadmin executable anywhere, execute the following command:
Securing the GlassFish Admin Console
The default admin password is blank. To update the admin password, run the following command:
Enter admin user name [default: admin]>admin
Enter the admin password> <blank>
Enter the new admin password>
Enter the new admin password again>
Command change-admin-password executed successfully.
After changing the admin password, we now need to enable the “secure admin” feature. It will ask for the credentials we added earlier.
We must restart GlassFish for the changes to take effect:
sudo systemctl restart glassfish
Now that we have a GlassFish Server that uses secure admin access, we can now test the server by deploying a sample WAR file.
First, we need to download a sample WAR file on domain1’s document root directory:
Now just $43 .99
cd /opt/glassfish5/glassfish/domains/domain1/docroot/ sudo wget https://github.com/dmatej/Glassfish/raw/master/v2/www/downloads/quickstart/hello.war
To deploy, run the following command. It will ask for admin credentials:
asadmin deploy hello.war
After successfully deploying, navigate to:
You should see the following message:
Hi, my name is Duke. What’s yours?
And that’s it! You now have a working GlassFish server on your Ubuntu 18.04 VPS.

Excellent this “How to Install Glassfish” . I used it to install on Ubuntu 20.04.01 Server and Glassfish 4.0
I’ve installed Glassfish on many servers – and always forget how to do it.
Nice simple instructions – worked well
