Install Openfire (Instant Messaging Server) on Ubuntu

Openfire is an open source instant messaging server, based on the XMPP protocol.

Prepare JRE

sudo apt-get install openjdk-7-jre

Download package
Make sure the latest version here: http://www.igniterealtime.org/downloads/index.jsp#openfire
In my case, for example, latest version is 3.8.2

wget http://www.igniterealtime.org/downloadServlet?filename=openfire/openfire_3_8_2.tar.gz -O openfire_3_8_2.tar.gz

Untar gz file, you'll get a openfire folder

tar -xvzf openfire_3_8_2.tar.gz

Edit openfire/conf/openfire.xml, enter your public server IP here:

<interface>127.0.0.1</interface> 

 Add a link to /etc/init.d so that you can start the daemon with a call to service:

ln -s YourOpenfirePath/bin/openfire /etc/init.d/

service openfire start/stop
