Openfire in Ubuntu server -Step by Step

 I have successfully completed the configuration in Ubuntu 9.10
Step 1:

#  apt-get update

Step 2 

Install LAMP (Linux-Apache Mysql and Php )

#sudo apt-get install php5 mysql-server apache2

While installing ,MySql will prompt to insert a password for the root user. Please remember this for the later configuration 

 Step 3

Install java6

 #  sudo apt-get install sun-java6-bin

 Check Java Version for cross verification

#    java –version

Step 4

Set java6 as your default.

 sudo update-alternatives --config java   

 Step 5

Check if php is working:

vi  /var/www/info.php

And put the below details

###########

<?php

phpinfo();

?>

############

Brouse http://yourServerip/info.php and you should  get the php info file

 #/etc/init.d/apache2 restart

Step 6

Now create a DB user using MySql

#   mysql -u root –p    

Note: Then it prompt for a password and put the password which you have given at the time of MySql installation

 mysql>  CREATE DATABASE openfire;

mySql > exit

Step 7

Download openfire from

http://www.igniterealtime.org/downloads/download-landing.jsp?file=openfire/openfire_3_6_4.tar.gz 

Or any other alternative place (use Google for this J)

Upload the tar.gz file into /opt folder in the server

# cp openfire_3_6_4.tar.gz  /opt/

#cd /opt/ 

 # tar -zxvf openfire_3_6_4.tar.gz   To un-tar the file

(Please check the file extracted  in to the opt folder itself)

Step 8

 Create a symlink

# ln -s /opt/openfire/bin/openfire  /etc/init.d/

 Make the symlink executable

 #chmod +x /etc/init.d/openfire

 Add openfire to our startup.

 #update-rc.d openfire defaults

 Fix the nohup error.
 Run the following command or you will get the following error: nohup: appending output to `nohup.out'

  nohup ls >ls.log 2>&1 &

Here you are .Now you can access the openfire using 

Step 9

http://your_server_ipaddress:9090/ .The rest of the configuration is very simple .
