Wichtige Konfiguration in php.ini

• PHP_VERS=8.2
• /etc/php/$PHP_VERS/fpm/php.ini

memory_limit = 2048M
upload_max_filesize = 512M
max_file_uploads = 100
post_max_size = 512M
max_execution_time = 600
max_input_time = 600
default_socket_timeout = 600
[Session]
#session.save_handler = files
session.save_handler = redis
session.save_path = "tcp://127.0.0.1:6379"

[opcache]
opcache.enable=1
opcache.memory_consumption=1024
opcache.interned_strings_buffer=512

[XDebug]
; Ist normalerweise in xdebug-spezifischer Konfiguration, z.B. mods.d/20-xdebug
;zend_extension="/usr/lib/php/20160303/xdebug.so"
xdebug.remote_port=9004
xdebug.remote_enable=On
xdebug.remote_host=192.168.100.100
; Alternativ: remote-Adresse selber ermitteln:
;xdebug.remote_connect_back=On
xdebug.remote_log=/var/log/php/xdebug.log
xdebug.remote_autostart=1
