This post shows students and new users steps to install GlassFish JAVA application server on Ubuntu Linux. GlassFish is a free, open-source server for deploying JAVA based applications.
GlassFish allows developers to build and publish JAVA applications at scale with ease. It also includes a complete administration console, clustering support, and other developer and production focused tools and features.
GlassFish project which was developed by Sun Microsystem is now supported and owned by Oracle corporation. Oracle has its own licensing terms that you may want to read carefully before using GlassFish at your business or enterprise.
Below we will show you how to install and configure GlassFish on Ubuntu Linux.
How to install GlassFish JAVA application server on Ubuntu Linux
As mentioned above, GlassFish is a free, open source server for deploying JAVA based applications for developers to build and publish applications with ease.
Below is how to install it on Ubuntu Linux.
In order to install GlassFish, you must first install Java. The open source Java should work great with GlassFish.
Run the commands below to install OpenJDK on Ubuntu Linux. This will install the current stable version of OpenJDK for Ubuntu Linux.
sudo apt update sudo apt install default-jdk
To check the version of Java installed, run the commands below:
That should output similar lines as shown below:
openjdk 11.0.15 2022-04-19 OpenJDK Runtime Environment (build 11.0.15+10-Ubuntu-0ubuntu0.20.04.1) OpenJDK 64-Bit Server VM (build 11.0.15+10-Ubuntu-0ubuntu0.20.04.1, mixed mode, sharing)
Once Java is installed, continue below to download GlassFish and install.
Now that JAVA is installed, run the commands below to download and extract GlassFish on Ubuntu Linux.
wget https://download.eclipse.org/ee4j/glassfish/glassfish-6.1.0.zip sudo unzip glassfish-6.1.0.zip -d /opt/
Next, create GlassFish systemd daemon file to manage GlassFish service. to do that, run the commands below to create a file named glassfish.service.
sudo nano /usr/lib/systemd/system/glassfish.service
Than copy and paste the lines below into the file and save.
[Unit] Description = GlassFish Server v6.1.0 After = syslog.target network.target [Service] User = root ExecStart = /usr/bin/java -jar /opt/glassfish6/glassfish/lib/client/appserver-cli.jar start-domain ExecStop = /usr/bin/java -jar /opt/glassfish6/glassfish/lib/client/appserver-cli.jar stop-domain ExecReload = /usr/bin/java -jar /opt/glassfish6/glassfish/lib/client/appserver-cli.jar restart-domain Type = forking [Install] WantedBy = multi-user.target
Once the file is created, run the commands below to reload systemd daemon by running the commands below.
sudo systemctl daemon-reload
You should be able to start and enable GlassFish service using the commands below.
sudo systemctl start glassfish sudo systemctl enable glassfish
To see if GlassFish is running, run the commands below.
sudo systemctl status glassfish
After running the status command above, you should see similar lines like the ones below:
● glassfish.service - GlassFish Server v6.1.0 Loaded: loaded (/lib/systemd/system/glassfish.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2022-05-30 17:41:40 CDT; 12s ago Main PID: 5124 (java) Tasks: 92 (limit: 4628) Memory: 306.4M CGroup: /system.slice/glassfish.service └─5124 /usr/lib/jvm/java-11-openjdk-amd64/bin/java -cp /opt/glassfish6/glassfish/modules/glassfish.jar -XX:+UnlockDiagnosticVMOptions -> May 30 17:41:27 ubuntu2004 systemd: Starting GlassFish Server v6.1.0... May 30 17:41:40 ubuntu2004 java: Waiting for domain1 to start ........... May 30 17:41:40 ubuntu2004 java: Successfully started the domain : domain1
By default, GlassFish administrative user has no password set up. You will probably want to create one for the admin user.
Run the commands below to do that.
sudo /opt/glassfish6/bin/asadmin --port 4848 change-admin-password
You should be prompted to type and confirm a new password for the admin account.
Enter admin user name [default: admin]> Enter the admin password> [ENTER] Enter the new admin password> [type new password] Enter the new admin password again> [retype password] Command change-admin-password executed successfully.
Once the password is created, you probably should run the commands below to secure the account.
sudo /opt/glassfish6/bin/asadmin --port 4848 enable-secure-admin
You should be prompted with the following prompts:
Enter admin user name> admin Enter admin password for user "admin"> You must restart all running servers for the change in secure admin to take effect. Command enable-secure-admin executed successfully.
After that, restart GlassFish service.
sudo systemctl restart glassfish
Now open your browser and browse to the server hostname of IP address followed by port 4848.
You will be greeted with GlassFish admin console. Type in the admin username and password created above to sign in.
Once you have successfully signed in, you should see a screen similar to the one below.
That should be it.
If you want to run a reverse proxy server to use a domain name or more advanced settings, read the posts below to learn how to set up a reverse proxy server with either Nginx or Apache to use with GlassFish.
