Installation guide
title: Installation
[Tutorial](https://www.techrepublic.com/article/how-to-install-nextcloud-22-on-ubuntu-server-20-04/)
Installed dependencies
Apache2
Webserver for Nextcloud. Apache2 has notorious issues with over-clogging memory usage (topping 100% of memory usage). In order to minimise memory usage, #APCu has been installed as a cache manager. In addition, Appache has been paired with:
- php-fpm for php7.4, enabling faster interaction between apache and backend.
- the 'event' multi-processing module (MPM) enabling decluttering of processing between ports & Apache
All relevant dependencies have been installed and the set-up tested. A comprehensive tutorial on the MPM switch can be found here or here.
php.ini files can be found at:
/etc/php/7.4/fpm/php.ini
/etc/php/7.4/apache2/php.ini
/etc/php/7.4/cli/php.ini
Certbot
Provides SSL certification from Let's Encrypt. Installation dependencies are different from Nginx and explained here
MySQL
Nothing particular to note on MySQL apart from initial set-up and user management.
Configuration file is under:
/etc/mysql/mysql.conf.d/mysqld.cnf
title: Optimise memory usage of mysql
In the conf file under the **_[mysqld]_** tag, add:
 
% Disable performance schema to hugely reduce RAM usage
performance_schema = OFF
In order to restart mysql, the command is:
sudo service mysql restart

Postfix
Mail Transfer Agent. Configuration is standard to allow for emails to be sent by programs / deamons / Nextcloud or others. Such a Postfix config is required for every server to work correctly.
APCu
Memory caching addon for Nextcloud. Memory caching management is provided by Nextcloud and needs to be set up as a system cron job. After installing APCu, the webserver needs to be restarted and the cron job defined:
- Define the cronjob
sudo crontab -u www-data -e
- Add cronjob
*/5 * * * * php -f /var/www/html/nextcloud/cron.php --define apc.enable_cli=1
- Verify that the cron job is added
sudo crontab -u www-data -l

SVG support is installed in the form of a package.
sudo apt-get update -y
sudo apt-get install -y libmagickcore-6.q16-6-extra
UFW
