Elgg is an award-winning social networking engine, delivering the building blocks that enable businesses, schools, universities and associations to create their own fully-featured social networks and applications. It offers blogging, microblogging, file sharing, networking, groups and a number of other features.

This appliance includes all the standard features in TurnKey Core, and on top of that:

  • Elgg configurations:

    • Elgg 7.0.5 is installed from the official complete release archive to /var/www/elgg. The upstream-published SHA-256 digest is verified during the build.

  • SSL support out of the box.

  • Adminer administration frontend for MySQL (listening on port

    12322 - uses SSL).

  • Postfix MTA (bound to localhost) to allow sending of email (e.g., password recovery).

  • Webmin modules for configuring Apache2, PHP, MySQL and Postfix.

Credentials (passwords set at first boot)

  • Webmin, SSH, MySQL: username root

  • Adminer: username adminer

  • Elgg: username admin

Updating Elgg

Notes:

  • Elgg will not be automatically updated and must be updated manually as per the instructions below.

  • AWS Marketplace users will need to prefix most commands with 'sudo'.

  • If you have any problems please contact TurnKey support:

To update, first create a TKLBAM or equivalent backup of the database, /var/www/elgg-data and application files. Review the release notes and the official Elgg upgrade documentation, then select a compatible Elgg 7 complete release. Record its asset URL and published SHA-256 digest from the official release before downloading it. For example, after setting version and sha256 to those reviewed values:

version=7.0.5
sha256=a369a5b97c22e31998d7ed3e107c410efbcd1d8f3a3edacea4b64af8a3027c10
archive=/tmp/elgg-$version.zip
staging=/var/www/elgg-$version
curl --fail --location \
    https://github.com/Elgg/Elgg/releases/download/$version/elgg-$version.zip \
    --output $archive
printf '%s  %s\n' "$sha256" "$archive" | sha256sum --check -
unzip -q $archive -d /tmp/elgg-release
mv /tmp/elgg-release/elgg-$version $staging
cp -a /var/www/elgg/elgg-config/settings.php \
    $staging/elgg-config/settings.php

Copy each site-specific plugin and reapply any recorded application customizations to $staging before the replacement. The database and /var/www/elgg-data remain in place. Then replace the application tree and run Elgg's database upgrade:

systemctl stop apache2
mv /var/www/elgg /var/www/elgg.previous
mv $staging /var/www/elgg
chown -R root:root /var/www/elgg
chown -R www-data:www-data /var/www/elgg-data
chmod 644 /var/www/elgg/elgg-config/settings.php
systemctl start apache2
turnkey-elgg-cli upgrade async -v

Keep /var/www/elgg.previous until the site has been checked. The complete release is the application package, so it must be replaced as a unit rather than updated by requiring elgg/elgg from its own Composer project.
