Configuration Overview
Debian's Apache2 default configuration is different from the upstream default configuration, and split into several files optimized for interaction with Debian tools. The configuration system is fully documented in /usr/share/doc/apache2/README.Debian.gz. Refer to this for the full documentation. Documentation for the web server itself can be found by accessing the manual if the apache2-doc package was installed on this server.

The configuration layout for an Apache2 web server installation on Debian systems is as follows:

apache2.conf is the main configuration file. It puts the pieces together by including all remaining configuration files when starting up the web server.
ports.conf is always included from the main configuration file. It is used to determine the listening ports for incoming connections, and this file can be customized anytime.
Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/ directories contain particular configuration snippets which manage modules, global configuration fragments, or virtual host configurations, respectively.
They are activated by symlinking available configuration files from their respective *-available/ counterparts. These should be managed by using our helpers a2enmod, a2dismod, a2ensite, a2dissite, and a2enconf, a2disconf . See their respective man pages for detailed information.
The binary is called apache2. Due to the use of environment variables, in the default configuration, apache2 needs to be started/stopped with /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not work with the default configuration.
Document Roots
By default, Debian does not allow access through the web browser to any file apart of those located in /var/www, public_html directories (when enabled) and /usr/share (for web applications). If your site is using a web document root located elsewhere (such as in /srv) you may need to whitelist your document root directory in /etc/apache2/apache2.conf.

The default Debian document root is /var/www/html. You can make your own virtual hosts under /var/www. This is different to previous releases which provides better security out of the box.

Reporting Problems
Please use the reportbug tool to report bugs in the Apache2 package with Debian. However, check existing bug reports before reporting a new bug.

Please report bugs specific to modules (such as PHP and others) to respective packages, not to the web server itself.

Documentation#

see /usr/share/doc/apache2/README.Debian.gz]
use "manual" on "apache2-doc" package

Start/Stop#

Note: do not use /usr/sbin/apache2 directly

/etc/init.d/apache2 start
/etc/init.d/apache2 stop
/etc/init.d/apache2 restart
	 
/usr/sbin/apachectl start
/usr/sbin/apachectl stop	

apachectl -v        # get version

Note: apachectl calls >systemctl start apache2<

Folders#

/usr/share/ - apache2 program
/var/www/html/ - default public content, all files & subfolders accessible by default
/var/www/html/index.html - Access Websites	
/etc/apache2/ - configuration
/var/log/apache2/ - logs

Configuration#

Main conf file is /etc/apache2/apache2.conf

IncludeOptional conf-enabled/*.conf
IncludeOptional sites-enabled/*.conf
IncludeOptional mods-enabled/*.load
IncludeOptional mods-enabled/*.conf

Validate routing and binding

apachectl -S
netstat -tulpn
lsof -i -P -n

Note: Apache tries to resolve the hostnames. If this is NOT successful the virtual entry is skipped ! You see this with apachectl -S if your config entry line is not showing up.
You may need to add the IP to your hosts file:

vi /etc/hosts
185.244.195.4   www.inetone.de inetone.de

Folder /etc/apache2/conf-available/

charset.conf
localized-error-pages.conf
other-vhosts-access-log.conf
security.conf
serve-cgi-bin.conf

Activate/Deactivate conf with

a2enmod, a2dismod, a2ensite, a2dissite, a2enconf, a2disconf

More config

/etc/apache2/sites-enabled
/etc/apache2/mods-enabled
ports.conf
envvars

Site configuration#

/etc/apache2/sites-enabled/000-default.conf -> ../sites-available/000-default.conf
/etc/apache2/sites-enabled/000-default-le-ssl.conf -> /etc/apache2/sites-available/000-default-le-ssl.conf

Apache VirtualHost Examples

| How to Multiple Sites @liquidweb.com

Redirects #

Use mod_rewrite (see docu

) only as last ressort, e.g. use simpler options if you have control over config files.
mod_alias

provides the Redirect and RedirectMatch directives at <VirtualHost>.
Note: the server name is derived from the IP address. So if have multiple sites based on the same IP the wrong VirtualHost may be taken.
See docu

:
When a request is received, the server first maps it to the best matching <VirtualHost> based on the local IP address and port combination only. Non-wildcards have a higher precedence. If no match based on IP and port occurs at all, the "main" server configuration is used.

If multiple virtual hosts contain the best matching IP address and port, the server selects from these virtual hosts the best match based on the requested hostname. If no matching name-based virtual host is found, then the first listed virtual host that matched the IP address will be used. As a consequence, the first listed virtual host for a given IP address and port combination is the default virtual host for that IP and port combination.

Deploying Angular#

Angular needs to map to the index.html for its own routing always. You need to add

<Directory "/var/www/html/angularIndexFileFolder">
  AllowOverride All
</Directory>

mod_rewrite (nevertheless)#

Apache Docu

| Activate

sudo a2enmod rewrite
sudo a2enmod actions 
/usr/sbin/apachectl start

You can configure via .htaccess file, but you should not, see docu

:
You should avoid using .htaccess files completely if you have access to httpd main server config file. Using .htaccess files slows down your Apache http server. Any directive that you can include in a .htaccess file is better set in a Directory block, as it will have the same effect with better performance.
So use <Directory> in main configuration at /etc/apache2/apache2.conf or
in the site configuration under <VirtualHost ...>.

<VirtualHost *>
  ServerName www.example.com
  RewriteEngine on
  RewriteCond %{HTTP_HOST} ^www.example.com
  RewriteRule ^/(.*)$ http://example.com/$1 [L,R=301]
</VirtualHost>
