apache2/apache2-httpd.conf

#
# /etc/apache2/httpd.conf 
#
# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:https://httpd.apache.org/docs/2.4/> for detailed information about
# the directives.

# Based upon the default apache configuration file that ships with apache,
# which is based upon the NCSA server configuration files originally by Rob
# McCool. This file was knocked together by Peter Poeml <poeml+apache@suse.de>.

# If possible, avoid changes to this file. It does mainly contain Include
# statements and global settings that can/should be overridden in the
# configuration of your virtual hosts.

# Quickstart guide:

### Global Environment ######################################################
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests.

# run under this user/group id
Include /etc/apache2/uid.conf

# - how many server processes to start (server pool regulation)
# - usage of KeepAlive
Include /etc/apache2/server-tuning.conf

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here.  If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.

# mod_reqtimeout protects the server from the so-called "slowloris"
# attack: The server is not swamped with requests in fast succession,
# but with slowly transmitted request headers and body, thereby filling up
# the request slots until the server runs out of them.
# mod_reqtimeout is lightweight and should deliver good results
# with the configured default values. You shouldn't notice it at all.
Include /etc/apache2/mod_reqtimeout.conf

# Fix for CVE-2014-0231 introduces new configuration parameter 
# CGIDScriptTimeout. This directive and its effect prevent request 
# workers to be eaten until starvation if cgi programs do not send 
# output back to the server within the timout set by CGIDScriptTimeout.
Include /etc/apache2/mod_cgid-timeout.conf

### 'Main' server configuration #############################################
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# <VirtualHost> definition.  These values also provide defaults for
# any <VirtualHost> containers you may define later in the file.
#
# All of these directives may appear inside <VirtualHost> containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#
Include /etc/apache2/default-server.conf


### Virtual server configuration ############################################
#
# VirtualHost: If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at
# <URL:https://httpd.apache.org/docs/2.4/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.
#
IncludeOptional /etc/apache2/vhosts.d/*.conf


# Note: instead of adding your own configuration here, consider 
#       adding it in your own file (/etc/apache2/httpd.conf.local)
#       putting its name into APACHE_CONF_INCLUDE_FILES in 
#       /etc/sysconfig/apache2 -- this will make system updates 
#       easier :)
