kill liferay script

Here’s a bash kill liferay script!

This should kill any running liferay or liferay social office on a linux system.

Open up your favorite editor and paste this in

#!/bin/bash
#
#Script name: kill_liferay.sh
#
#Purpose: To kill any running instance of liferay on a linux system
#
#Usage: ./kill_liferay.sh
#
for pid in `ps aux | grep java | grep liferay | grep tomcat  | awk '{print $2}'`
do
        echo "Liferay is running with pid $pid ..."
        kill $pid
        if ! kill $pid > /dev/null 2>&1; then
                echo "Could not send SIGTERM to process $pid .. trying kill -9" >&2
                if ! kill -9 $pid > /dev/null 2>&1; then
                        echo "Unable to kill $pid with kill -9"
                else
                        echo "Successfully killed Liferay with PID $pid!"
                fi
        else
                echo "Successfully killed Liferay with PID $pid!"
        fi
done

 

Save the file something like kill_liferay.sh

Next you’ll need to:

# chmod +x kill_liferay.sh

When to kill liferay?

When it is not responding. Here is a nice script to detect just that!

Note the /etc/init.d/liferay script is using the kill liferay script amongst other things!

#!/bin/bash
#
# /usr/local/bin/liferay.cron.sh
if curl -I -L http://localhost:8080 | grep "Liferay Portal" > /dev/null; then
	echo "Liferay is up" > /dev/null
else
	/etc/init.d/liferay restart
fi

/etc/init.d/liferay

#!/bin/bash
