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

 

Security

Program name	Type	Description
fail2ban	Daemon	Blocks suspicious attempts to login
unattended-upgrades	Program	Enables automatic updates of installed programs and OS
logwatch	Daemon	Monitors activity on server and sends activity logs

 

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:

1. Define the cronjob

sudo crontab -u www-data -e

2. Add cronjob

*/5 * * * * php -f /var/www/html/nextcloud/cron.php --define apc.enable_cli=1

3. Verify that the cron job is added

sudo crontab -u www-data -l

 

SVG support

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
