Apache Notes
Debian 9 stretch backports for Apache2, nothing beyond v2.4.25, but can use the sury.org apache2 repository which currently has v2.4.43.

AllowOverride directive | Only available in <Directory> sections | When the server finds an .htaccess file, it needs to know which directives declared in it can override earlier config directives. AllowOverride is valid only in <Directory> sections specified without regular expressions, not in <Location>, <DirectoryMatch> or <Files> sections. When this directive is set to None and AllowOverrideList is set to None, .htaccess files are completely ignored. In this case, the server will not even attempt to read .htaccess files in the filesystem. When this directive is set to All, then any directive which has the .htaccess Context is allowed in .htaccess files.

Apache Configuration File's Structure and Best Practices
– In Debian based systems Apache configuration files are located in the /etc/apache2 directory.
– The main Apache configuration file is /etc/apache2/apache2.conf.
– The ports that Apache will listen to are specified in the /etc/apache2/ports.conf file.
– Apache Virtual Hosts files are located in the /etc/apache2/sites-available directory. The configuration files found in this directory are not used by Apache unless they are linked to the /etc/apache2/sites-enabled directory.
– You can activate a virtual host directive by creating a symlink using the a2ensite command from the configuration files found in the sites-available directory to the sites-enabled directory. To deactivate a virtual host use the a2dissite command.
– It is highly recommended to follow the standard naming convention, for example if your domain name is mydomain.com then the domain configuration file should be named /etc/apache2/sites-available/mydomain.com.conf
– Configuration files that are used for loading various Apache modules are located in the /etc/apache2/mods-available directory. Configurations in the mods-available directory can be enabled by creating a symlink to the /etc/apache2/mods-enable directory using the a2enconf command and disabled with the a2disconf command.
– Files containing global configuration fragments are stored in the /etc/apache2/conf-available directory. Files in the conf-available directory can be enabled by creating a symlink to the /etc/apache2/conf-enabled using the a2enconf command and disabled with the a2disconf command.
– Apache log files (access.log and error.log) are located in the /var/log/apache directory. It is recommended to use different access and error log files for each virtual host.
– You can set your domain document root directory to any location you want. The most common locations for webroot include:
– /home/<user_name>/<site_name>
– /var/www/<site_name>
– /var/www/html/<site_name>
– /opt/<site_name>
Apache allows additional configuration on a per-directory basis via .htaccess files. This architecture allows non-privileged users to control certain aspects of their website without granting them permission to edit the main config. This is big!
