How to install Jabberd2 on Ubuntu Server 12.04

Installation

To install jabberd2, in a terminal enter:

sudo apt-get install jabberd2

Configuration

A couple of XML configuration files will be used to configure jabberd2 for Berkely DB user authentication. This is a very simple form of authentication.

First, edit /etc/jabberd2/sm.xml changing:

6   <id>localhost.localdomain</id>

Note: Replace localhost.localdomain with the hostname, or other id, of your server.

Look like:

6   <id>192.168.1.200</id>

Note: 192.168.1.200 is VENUS server

Now in the <storage> section change:

 70   <storage>
 71     <!-- Dynamic storage modules path -->
 72     <path>/usr/lib/jabberd2</path>
 73 
 74     <!-- By default, we use the MySQL driver for all storage -->
 75     <driver>mysql</driver>
 76 
 ······
101     <!-- MySQL driver configuration -->
102     <mysql>
103       <!-- Database server host and port -->
104       <host>localhost</host>
105       <port>3306</port>
106 
107       <!-- Database name -->
108       <dbname>jabberd2</dbname>
109 
110       <!-- Database username and password -->
111       <user>jabberd2</user>
112       <pass>secret</pass>

Note: Replace <dbname>, <user>, <pass> with your database name, username and password

Next, edit /etc/jabberd2/c2s.xml in the section change:

125     <id register-enable='true'>localhost.localdomain</id>

Look like:

125     <id register-enable='true'>192.168.1.200</id>

And in the <authreg> section change:

320   <authreg>
321     <!-- Dynamic authreg modules path -->
322     <path>/usr/lib/jabberd2</path>
323 
324     <!-- Backend module to use -->
325     <module>mysql</module>
······
372     <!-- MySQL module configuration -->
373     <mysql>
374       <!-- Database server host and port -->
375       <host>localhost</host>
376       <port>3306</port>
377 
378       <!-- Database name -->
379       <dbname>jabberd2</dbname>
380 
381       <!-- Database username and password -->
382       <user>jabberd2</user>
383       <pass>secret</pass>

Note: Replace <dbname>, <user>, <pass> with your database name, username and password

Finally, restart jabberd2 to enable the new settings:

sudo /etc/init.d/jabberd2 restart
or
sudo service jabberd2 restart

You should now be able to connect to the server using a Jabber client.
