Step 1: Update Your System

As usual we do, first of all update your system to have the latest updates installed.

Step 2: Download Ejabberd Package

Visit the Ejabberd official page to download the latest version of ejabberd. Here I’m going to use the 20.04 version.

After the successful installation, start and enable the services on Ubuntu 20.04.

sudo cp $(sudo find / -name ejabberd.service) /etc/systemd/system

Add ejabberdctl command location to your PATH

$ sudo find / -name ejabberdctl
/opt/ejabberd-20.04/bin/ejabberdctl

Then add path to the .bashrc file

sudo nano ~/.bashrc

And set it like you see here after.

PATH=$PATH:/opt/ejabberd-20.04/bin/

Finally source the file

source ~/.bashrc

Step 5: Add An Admin User To Ejabberd

Now, add the admin user for administrative purposes to Ejabberd.

Follow the below syntax to add the user.

ejabberdctl register <username> <server_hostname> <user_password>
jabberdctl register osradar ejabberd.example.com StrongPassword
User admin@example.com successfully registered

Now, edit the ejabberd configuration file to provide the administrative rights to the XMPP account created above.

sudo nano /opt/ejabberd/conf/ejabberd.yml
acl:
     admin:
      user:
- "osradar@ejabberd.example.com"

User format:

"username@servername"

Step 6: Access Ejabberd Web Dashboard

You can find the ejabberd Web Admin at

http://server_ip_address_or_hostname:5280/admin/.

And verify if the port is bound.

ss -tunelp | grep 5280

Now, visit the above URL and then provide the credentials details as created earlier to login to the dashboard.

Upon visiting the link, You’ll see the similar Web Admin.
