Ejabberd is a high-performance Jabber/XMPP server, written in Erlang. It comes with a built-in web-based management interface.
To install the server and its components, run:
apt-get install ejabberd
After it is installed, you need to edit the configuration file found at /etc/ejabberd/ejabberd.cfg.
In the configuration file, you need to add the hostname you want the server to use (unless you only want to run on localhost). Change:
{hosts, ["localhost"]}.to
{hosts, ["localhost","servername.com"]}.In addition, you need to create an admin user. Change:
{acl, admin, {user, "", "localhost"}}.to
{acl, admin, {user, "admin-name", "servername.com"}}.Now, restart the service:
service ejabberd restart
Finally, set the password for your admin user:
ejabberdctl register admin-name servername.com password
All set.
For any further configuration, you can log in to the web-based management panel. In your web browser, go to http://servername.com:5280/admin and enter the admin username and password.
