Students and teachers can store their documents, calendars, contacts and photos locally within [Nextcloud](https://nextcloud.com), which is much like having a (local) version of Dropbox or Google Drive on your very own [Internet-in-a-Box](https://internet-in-a-box.org).
(1) Set these 2 variable in [/etc/iiab/local_vars.yml](http://FAQ.IIAB.IO#What_is_local_vars.yml_and_how_do_I_customize_it%3F) prior to installing Internet-in-a-Box:
To further refine Nextcloud access controls based on IPv4 addresses, you can edit `/etc/apache2/sites-available/nextcloud.conf`_after_ it's created by this template: [/opt/iiab/iiab/roles/nextcloud/templates/nextcloud.conf.j2](https://github.com/iiab/iiab/blob/master/roles/nextcloud/templates/nextcloud.conf.j2)</strike>
(3) Be aware of `nginx_high_php_limits: True` in your /etc/iiab/local_vars.yml, which allocates important RAM/resources to PHP, and is effectively auto-enabled for Nextcloud ([PR #3624](https://github.com/iiab/iiab/pull/3624)). Verify that your Internet-in-a-Box server has enough RAM and disk! And _after_ Nextcloud is installed, verify and evaluate these 6 settings in `/etc/php/[ACTUAL PHP VERSION]/fpm/php.ini` to be sure:
Useful PHP recommendations for these settings (while largely tailored to WordPress, and aimed at very low-end hardware) can be found here: [/opt/iiab/iiab/roles/www_options/tasks/php-settings.yml#L55-L110](../www_options/tasks/php-settings.yml#L55-L110)
(4) Verify system requirements and recommendations for the [latest version Nextcloud](https://github.com/nextcloud/server/wiki/Maintenance-and-Release-Schedule):
Do not install the [Nextcloud News](https://apps.nextcloud.com/apps/news) app (an RSS/Atom Feed reader) if your OS is 32-bits: [#3069](https://github.com/iiab/iiab/issues/3069)
