ejabberd is available in the Ubuntu repositories, so it’s easy to download and install. Simply run the following command to install eJabberd.

Step #2 Configure eJabberd

By default, hostname used by eJabberd is ‘localhost’, which can be modified from config file. For this installation we are using domain im.techoism.com in configuration. You may only use localhost for you local system, but for remote server use a domain or sub-domain.

# sudo vim /etc/ejabberd/ejabberd.cfg

In the config file, locate the following:

%% Admin user
{acl, admin, {user, "admin","localhost"}}.

Modify this line to represent the correct Admin user.

%% Admin user
{acl, admin, {user, "admin","localhost"}}.
{acl, admin, {user, "admin","im.techoism.com"}}.

In the config file, locate the following:

%% Hostname
{hosts, ["localhost"]}.

Modify this line to represent the correct host name.

%% Hostname
{hosts, ["localhost","im.techoism.com"]}.

Step #3 Restart eJabberd

After making all above configuration, let’s restart eJabberd service using following command.

# sudo service ejabberd restart

Step #4 Admin Accounts

Now you need to create admin accounts for both virtual hosts localhost and im.techoism.com.

For localhost:

# ejabberdctl register administrator localhost secretpassword

User administrator@localhost successfully registered

For Domain:

# ejabberdctl register administrator im.techoism.com secretpassword

User administrator@im.techoism.com successfully registered

Step #5 Access eJabberd Web Panel

By default eJabberd admin web panel use port 5280. Access eJabberd web panel using following URL:
