proxy

Conf files

# enable a conf a2enconf [conf] # disable a conf a2disconf [conf] # list enabled config a2query -c # list all enables conf files sudo apachectl -t -D DUMP_INCLUDES

Security

/etc/apache2/conf-available/security.conf

# Hide server information like Apache and PHP versions ServerTokens Prod # Turn off your server's signature ServerSignature Off # Setting this header will prevent MSIE from interpreting files as something else than declared by the content type in the HTTP headers. # Requires mod_headers to be enabled (a2enmod headers). Header set X-Content-Type-Options: "nosniff" # Setting this header will prevent other sites from embedding pages from this site as frames. # Requires mod_headers to be enabled (a2enmod headers). Header set X-Frame-Options: "sameorigin"

Modules

# activer un module a2enmod [module] # désactiver un module a2dismod [module] # lister les modules chargés apache2ctl -M

Activer un module déjà activé ne pose pas de problème. Même chose pour la désactivation.

PHP

# vérifier qu'un module a bien été chargé php -m | grep <module-name> # activer un module phpenmod <module-name> # redémarrer le serveur apache après ça

/etc/php/7.2/apache2/php.ini

memory_limit = 512M

PHP-FPM

Par defaut apache utilise mod_php, moins performant que php-fpm et ne permettant pas d'utiliser HTTP/2.

sudo apt install php-fpm sc-status php7.4-fpm # désactiver les modules php et mpm_prefork sudo a2dismod php7.4 sudo a2dismod mpm_prefork # activer la configuration php-fpm et le module mpm_event # sudo a2enmod proxy_fcgi setenvif sudo a2enconf php7.4-fpm sudo a2enmod mpm_event

Configuration: /etc/apache2/conf-available/php7.4-fpm.conf

create a new pool

Permet d'avoir une configuration différente par site.

/etc/php/7.4/fpm/pool.d/new.conf

[new] listen = /run/php/php7.4-fpm-new.sock

/etc/apache2/sites-available/mysite.conf

<FilesMatch ".+\.ph(ar|p|tml)$"> SetHandler "proxy:unix:/run/php/php7.4-fpm-new.sock|fcgi://localhost" </FilesMatch>

force a specific PHP version for a site

/etc/apache2/sites-available/mysite.conf

<FilesMatch "\.php$"> # force PHP 7.4 SetHandler "proxy:unix:/run/php/php7.4-fpm.sock|fcgi://localhost" </FilesMatch>

monitoring

/etc/php/7.4/fpm/pool.d/www.conf

pm.status_path = /status

/etc/apache2/sites-available/000-default.conf

<LocationMatch "/status"> SetHandler "proxy:unix:/run/php/php7.4-fpm.sock|fcgi://localhost" </LocationMatch> # enable access to the realtime status web page Alias /realtime-status "/usr/share/php/7.4/fpm/status.html"

• Raw status info: http://<server>/status
• HTML status info: http://<server>/realtime-status

No / at the end of the url

HTTP/2

Utiliser php-fpm car incompatible avec mod_php.

a2enmod http2

Droits d'accès des dossiers et fichiers

Le serveur Apache accède aux dossiers et fichiers via l'utilisateur www-data.
