Ejabberd is an open source XMPP server designed for speed and efficiency. This tool has been built from the ground-up with fault-tolerance, easy configurations, and scalability. Scaling up is a matter of adding extra Virtual Machines to the cluster. Ejabberd has support for authenticating modules such as Mnesia, SQL, LDAP or through the use of external scripts.

• SQL databaseslike MySQL or PostgreSQL

Change Host and Domain name by changes in ejabberd.yml

Path : /opt/ejabberd/conf/ejabberd.yml

1. Configure this:

Make sure that Jabber clients in other machines know that 1.1.1.1 is the IP address of the machine where you have ejabberd installed. Otherwise, instead of “1.1.1.1”, you must put the real IP address, or the machine network name.

2. Grant admin rights to an account
3. Create that account:
4. Now you can login to that account with a Jabber client. And WebAdmin must show all the admin pages

you can change 1.1.1.1 do your doamin also

Step 5: Access ejabberd Web Admin

• The Web Admin should be accessible on http://serveripaddressorhostname:5280/admin/.

  Check if the port is bound:

  ss -tunelp | grep 5280

  If you have ufw firewall, allow port5280:

  sudo ufw allow 5280

  Open the ejabberd web URL in your browser. Input the username and password configured earlier
