Nextcloud 22 with PHP 8.0 Retrofitting and Optimizing
By jplee ~ Published – 2022/02/22
By following this guide you will be able to setup Nextcloud 22 with the current PHP version 8.x to operate, can we go for a server installation according to this guide. (Nextcloud 20 manual installation guide ) From PHP 7.x to PHP 8.x switch to log in via SSH to the Server and change in the privileged user mode. However, backup your server first! Then, switch into the privileged user mode:
sudo -s In order to prevent access to the nextcloud during the conversion, we can move Nextcloud into the maintenance mode
and stop all the relevant server connected services:
sudo -u www-data php /var/www/nextcloud/occ maintenance:mode --on service nginx stop && service redis-server stop && service php7.4-fpm stop && service mariadb stop Now that all services are stopped, we will remove the previously used PHP packages:
apt remove --purge -y php* && apt autoremove -y All packages will be removed, so we need to install the package PHP 8.x:
apt update -q4 && apt install -y php8.0-{fpm,gd,mysql,pgsql,curl,xml,zip,intl,mbstring,bz2,ldap,apcu,bcmath,gmp,imagick,igbinary,redis,smbclient,cli,common,opcache,readline} imagemagick Before we start with the optimization of PHP, we ensure that by coping the configuration files:
cp /etc/php/8.0/fpm/pool.d/www.conf /etc/php/8.0/fpm/pool.d/www.conf.bak
cp /etc/php/8.0/fpm/php-fpm.conf /etc/php/8.0/fpm/php-fpm.conf.bak
cp /etc/php/8.0/cli/php.ini /etc/php/8.0/cli/php.ini.bak
cp /etc/php/8.0/fpm/php.ini /etc/php/8.0/fpm/php.ini.bak
cp /etc/php/8.0/fpm/php-fpm.conf /etc/php/8.0/fpm/php-fpm.conf.bak
cp /etc/php/8.0/mods-available/apcu.ini /etc/php/8.0/mods-available/apcu.ini.bak
cp /etc/ImageMagick-6/policy.xml /etc/ImageMagick-6/policy.xml.bak
PHP will be require to adapt to your System and some of the Parameters, run the following lines:
AvailableRAM=$(awk '/MemAvailable/ {printf "%d", $2/1024}' /proc/meminfo)
AverageFPM=$(ps --no-headers -o rss,cmd,' - C php-fpm8.0 | awk '{ sum+=$1 } END { printf ("%d\n", sum/NR/1024, 'M') }')
FPMS=$((AvailableRAM/AverageFPM))
PMaxSS=$((FPMS*2/3))
PMinSS=$((PMaxSS/2))
PStartS=$(((PMaxSS+PMinSS)/2))
Now, do all of the following optimizations to PHP files.

PHP 8.x is now installed and optimized, so that we can restart the service.
service php8.0-fpm restart Within the nginx web server, we need to change to the updated PHP 8.0. Inorder to do this, we open the following file.
vim /etc/nginx/nginx.conf And replace the socket entry 7.4 with 8.0:
[...]
upstream php-handler {
server unix:/run/php/php8.0-fpm.sock;
}
[...]
Test that nginx web server is properly functioning correctly.
nginx -t Now restart with all of the relevant server services
sudo -u www-data php /var/www/nextcloud/occ maintenance:mode --off service redis-server restart && service mariadb restart && service nginx restart FYI: We may need to set system default PHP to version 8.0. There are two ways to do this:
sudo update-alternatives --set php /usr/bin/php8.0
sudo update-alternatives --config php
service php8.0-fpm restart
Congratulations, you now have your own personal data on your own secured Nextcloud 22 system with PHP 8.0, enjoy!
