Swarm 2017.2 Guide (August 2017)

Register a short domain name, or if you control your own DNS server, a short domain name for your network.

Point the short domain name at your Swarm host.

Edit the SWARM_ROOT/data/config.php file and add the following configuration block:

<?php
    // this block should be a peer of 'p4'
    'short_links' => array(
        'hostname'  => 'myho.st',
    ),

Replace myho.st with the short domain name you registered/configured.

If your Swarm is configured to use use HTTPS, a custom port, a sub-folder, or any combination of these custom installation options, the short links configuration block should look like:

<?php
    // this block should be a peer of 'p4'
    'short_links' => array(
      'external_url' => 'https://myho.st:port/sub-folder',
    ),

Replace myho.st with the short domain name you have registered/configured.

If you have not configured Swarm to use HTTPS, replace https:// with http://.

If you have configured Swarm to run on a custom port, replace :port with the correct custom port. Otherwise, remove :port.

If you have configured Swarm to run in a sub-folder, replace /sub-folder with the correct sub-folder name. Otherwise, remove /sub-folder.
