PHP Probleme und Fehler

Nach Update auf neu PHP Version ist kein Login in Nextcloud mehr möglich

Der Zufriff des Web Server Nutzers „nginx“ o. „www-data“ braucht Schreibzugriff im PHP Ordner:

ls -la /var/lib/php/

chown -R nginx /var/lib/php/
systemctl restart php-fpm
systemctl restart nginx

PHP Upgrade in Debian aktualisiert Systemd Daemon falsch, der dann nicht mehr startet

/lib/systemd/system/php7.4-fpm.service

[Unit]
Description=The PHP 7.4 FastCGI Process Manager
Documentation=man:php-fpm7.4(8)
After=network.target nginx.service

[Service] 
Type=notify
RuntimeDirectory=php
RuntimeDirectoryMode=755
RuntimeDirectoryPreserve=yes
PIDFile=/var/run/php/php7.4-fpm.pid
ExecStart=/usr/sbin/php-fpm7.4 --nodaemonize --fpm-config /etc/php/7.4/fpm/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID

[Install]
WantedBy=multi-user.target

PHP Module nach-installieren

apt install php7.4-gmp

Herausfinden, mit welcher Ini-Datei PHP läuft

root@server:/# php --ini
Configuration File (php.ini) Path: /etc/php/7.4/cli
Loaded Configuration File:         /etc/php/7.4/cli/php.ini
Scan for additional .ini files in: /etc/php/7.4/cli/conf.d
Additional .ini files parsed:      /etc/php/7.4/cli/conf.d/10-mysqlnd.ini,
/etc/php/7.4/cli/conf.d/ [...]

Das Modul sollte eigentlich bei der Installation in die richtige INI Datei eingetragen worden sein. Ist das nicht der Fall, muss es noch in /etc/php/7.4/cli/php.ini oder /etc/php/7.4/cli/conf.d/20-gmp.ini eingetragen werden:

extension=gmp.so

Upgrade auf php 8

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
apt remove --purge -y php* && apt autoremove -y
apt update -q4 && apt install -y php8.0-{fpm,gd,mysql,curl,xml,zip,intl,mbstring,bz2,ldap,apcu,bcmath,gmp,imagick,igbinary,redis,smbclient,cli,common,opcache,readline} imagemagick
