To make the Glassfish Server auto start with startup, we need to setting up an init script, which helps us to manage all Glassfish Server startup events easily. And also make Glassfish start up automatically whenever Ubuntu is rebooting.

This script file is glassfish to be created at /etc/init.d/. For managing all Glassfish Server startup events, it ships with the asadmin tool. Use this tool in the startup script as follows,

Create or edit glassfish file

Shell

sudo nano /etc/init.d/glassfish

1

sudo nano /etc/init.d/glassfish

Paste the following lines in the file

#!/bin/sh

#to prevent some possible problems
export AS_JAVA=/usr/lib/jvm/jdk1.8.0

GLASSFISHPATH=/home/glassfish/bin

case "$1" in
start)
echo "starting glassfish from $GLASSFISHPATH"
sudo -u glassfish $GLASSFISHPATH/asadmin start-domain domain1
;;
restart)
$0 stop
$0 start
;;
stop)
echo "stopping glassfish from $GLASSFISHPATH"
sudo -u glassfish $GLASSFISHPATH/asadmin stop-domain domain1
;;
*)
echo $"usage: $0 {start|stop|restart}"
exit 3
;;
esac
:

#!/bin/sh

#to prevent some possible problems

export AS_JAVA=/usr/lib/jvm/jdk1.8.0

GLASSFISHPATH=/home/glassfish/bin

case "$1" in

start)

echo "starting glassfish from $GLASSFISHPATH"

sudo -u glassfish $GLASSFISHPATH/asadmin start-domain domain1

;;

restart)

$0 stop

$0 start

;;

stop)

echo "stopping glassfish from $GLASSFISHPATH"

sudo -u glassfish $GLASSFISHPATH/asadmin stop-domain domain1

;;

echo $"usage: $0 {start|stop|restart}"

exit 3

;;

esac

Now, glassfish startup script is created. We need to add this file in startup to make Glassfish Server autostart during Ubuntu startup. Follow these steps,

Make the startup script file executable

Shell

sudo chmod a+x /etc/init.d/glassfish

1

sudo chmod a+x /etc/init.d/glassfish
Add this file to Ubuntu startup boot

Shell

sudo update-rc.d glassfish defaults

1

sudo update-rc.d glassfish defaults

That’s it. Now, restart Ubuntu and check if it really autostart the Glassfish Server.

You can also manage Glassfish Server startup events as follows,

Start the server

Shell

/etc/init.d/glassfish start

1

/etc/init.d/glassfish start
Stop the server

Shell

/etc/init.d/glassfish stop

1

/etc/init.d/glassfish stop
Restart the server

Shell

/etc/init.d/glassfish restart

1

/etc/init.d/glassfish restart

Some of the important server related problems will be solved only using shell access to the server. To access the cPanel server shell using SSH, there must be an SSH client installed on PC. Most of the Linux distros include SSH client software by default. If it is not installed, then it can be easily installed with following commands,

For Ubuntu: apt-get install openssh-client
For CentOS: yum install openssh-clients

After installation, follow these steps to access the cPanel shell with SSH from Linux:

Login to cPanel and go to Security > SSH/Shell Access to generate SSH key pair.
Click Manage SSH Keys > Generate a New Key. You should use a password to protect the key. You will be asked the password each time you use the key.
In Public Keys section click ‘Manage Authorization’ and ‘Authorize’
In Private Keys section click, Vew/Download then download the key (id_dsa or id_rsa) to your PC.
Save it to ~/.ssh directory on your Linux machine under a meaningful name to not overwrite your existing keys for example id_dsa.myjavahost
Now make sure permissions are correct on the key (one-time task) and connect:

Shell

mypc:~$ chmod 600 .ssh/id_dsa mypc:~$ ssh -p1033 -i .ssh/id_dsa yourusername@yourservername Enter passphrase for key '.ssh/id_dsa':

1
2
3

mypc:~$ chmod 600 .ssh/id_dsa
mypc:~$ ssh -p1033 -i .ssh/id_dsa yourusername@yourservername
Enter passphrase for key '.ssh/id_dsa':
Provide the password for the key, set up in step #2

You should be logged in by now.
