#
# This is the main Apache HTTP server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
# for a discussion of each configuration directive.
#
# See the httpd.conf(5) man page for more information on this configuration,
# and httpd.service(8) on using and configuring the httpd service.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so 'log/access_log'
# with ServerRoot set to '/www' will be interpreted by the
# server as '/www/log/access_log', where as '/log/access_log' will be
# interpreted as '/log/access_log'.
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path. If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used. If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "/etc/httpd"
#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 80
#
# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.
#
# Example:
# LoadModule foo_module modules/mod_foo.so
#
Include conf.modules.d/*.conf
#
# If you wish httpd to run as a different user or group, you must run
# httpd as root initially and it will switch.
#
# User/Group: The name (or #number) of the user/group to run httpd as.
# It is usually good practice to create a dedicated user and group for
# running httpd, as with most system services.
#
User apache
Group apache
# '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.
#
#
# ServerAdmin: Your address, where problems with the server should be
# e-mailed. This address appears on some server-generated pages, such
# as error documents. e.g. admin@your-domain.com
#
ServerAdmin root@localhost
#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
#ServerName www.example.com:80

# Redirect: Allows you to tell clients about documents that used to

# will make a new request for the document at its new location.
# Example:
# Redirect permanent /foo http://www.example.com/bar

# Alias: Maps web paths into filesystem paths and is used to
# access content that does not live under the DocumentRoot.
# Example:
# Alias /webpath /full/filesystem/path
#
# If you include a trailing / on /webpath then the server will
# require it to be present in the URL. You will also likely
# need to provide a <Directory> section to allow access to
# the filesystem path.
#
# ScriptAlias: This controls which directories contain server scripts.
# ScriptAliases are essentially the same as Aliases, except that
# documents in the target directory are treated as applications and
# run by the server when requested rather than as documents sent to the
# client. The same rules about trailing "/" apply to ScriptAlias

<title>Description</title>
<para>The main configuration file for the <command>httpd</command> daemon is
<filename>/etc/httpd/conf/httpd.conf</filename>. The syntax of
this file is described at <ulink
url="https://httpd.apache.org/docs/2.4/configuring.html"/>, and
the full set of available directives is listed at <ulink
url="https://httpd.apache.org/docs/2.4/mod/directives.html"/>.
</para>
<refsect2>
<title>Configuration structure</title>
<para>The main configuration file
(<filename>httpd.conf</filename>) sets up various defaults and
includes configuration files from two directories -
<filename>/etc/httpd/conf.modules.d</filename> and
<filename>/etc/httpd/conf.d</filename>. Packages containing
loadable modules (like <option>mod_ssl.so</option>) place files
in the <filename>conf.modules.d</filename> directory with the
appropriate <option>LoadModule</option> directive so that module
is loaded by default.</para>
<para>Some notable configured defaults are:.</para>
<variablelist>
<varlistentry>
<term><option>DocumentRoot @DOCROOT@/html</option></term>
<listitem><para>The default document root from which content
is served.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>Listen 80</option></term>
<listitem><para>The daemon lists on TCP port 80.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>ErrorLog "logs/error_log"</option></term>
<listitem><para>Error messages are logged to
<filename>@LOGDIR@/error_log</filename>.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>ScriptAlias /cgi-bin/ "@DOCROOT@/cgi-bin/"</option></term>
<listitem><para>CGI scripts are served via the URL-path <option>/cgi-bin/</option>.</para></listitem>
</varlistentry>
</variablelist>
<para>To remove any of the default configuration provided in
separate files covered below, replace that file with an empty
file rather than removing it from the filesystem, otherwise it
may be restored to the original when the package which provides
it is upgraded.</para>
</refsect2>
<refsect2>
<title>MPM configuration</title>
<para>The configuration file at
<filename>/etc/httpd/conf.modules.d/00-mpm.conf</filename> is
used to select the multi-processing module (MPM), which governs
how <command>httpd</command> divides work between processes
and/or threads at run-time. Exactly one
<option>LoadModule</option> directive must be uncommented in
this file; by default the <option>@MPM@</option> MPM is enabled.
For more information on MPMs, see <ulink
url="https://httpd.apache.org/docs/2.4/mpm.html"/>.</para>
<para>If using the <emphasis>prefork</emphasis> MPM, the
"httpd_graceful_shutdown" SELinux boolean should also be
enabled, since with this MPM, httpd needs to establish TCP
connections to local ports to successfully complete a graceful
restart or shutdown. This boolean can be enabled by running the
command: <command>semanage boolean -m --on
httpd_graceful_shutdown</command></para>
</refsect2>
<refsect2>
<title>Module configuration files</title>
<para>Module configuration files are provided in the
<filename>/etc/httpd/conf.modules.d/</filename> directory. Filenames
in this directory are by convention prefixed with two digit numeric
prefix to ensure they are processed in the desired order. Core
modules provide with the <command>httpd</command> package are
loaded by files with a <option>0x-</option> prefix to ensure
these are loaded first. Only filenames with a
<option>.conf</option> suffix in this directory will be
processed.</para>
<para>Other provided configuration files are listed below.
<variablelist>
<varlistentry>
<term><filename>/etc/httpd/conf.modules.d/00-base.conf</filename></term>
<listitem><para>The set of core modules included with
<command>httpd</command> which are all loaded by

<title>Other configuration files</title>
<para>Default module configuration files and site-specific
configuration files are loaded from the
<filename>/etc/httpd/conf.d/</filename> directory. Only files
with a <option>.conf</option> suffix will be loaded. The
following files are provided:
<variablelist>
<varlistentry>

<listitem><para>This file configures a TLS
<option>VirtualHost</option> listening on port
<option>443</option>. If the default configuration is used,
the referenced test certificate and private key are
generated the first time <command>httpd.service</command> is

<title>Instantiated services</title>
<para>As an alternative to (or in addition to) the
<command>httpd.service</command> unit, the instantiated template
service <command>httpd@.service</command> unit file can be used,
which starts <command>httpd</command> using a different
configuration file to the default. For example,
<command>systemctl start httpd@foobar.service</command> will
start httpd using the configuration file

<title>Description</title>
<para>This manual page describes the <command>systemd</command>
unit files used to integrate the <command>httpd</command> daemon
with <command>systemd</command>. Two main unit files are
available: <command>httpd.service</command> allows the
<command>httpd</command> daemon to be run as a system service, and
<command>httpd.socket</command> allows httpd to be started via
socket-based activation. Most systems will use
<command>httpd.service</command>.</para>
<para>The <command>apachectl</command> command has been modified
to invoke <command>systemctl</command> for most uses, so for
example, running <command>apachectl start</command> is equivalent
to running <command>systemctl start httpd.service</command>. This
ensures that the running httpd daemon is tracked and managed by
<command>systemd</command>. In contrast, running
<command>httpd</command> directly from a root shell will start the
service outside of <command>systemd</command>; in this case,
default security restrictions described below (including, but not
limited to, SELinux) will not be enforced.</para>
<refsect2>
<title>Changing default behaviour</title>
<para>To change the default behaviour of the httpd service, an
<emphasis>over-ride</emphasis> file should be created, rather
than changing
<filename>/usr/lib/systemd/system/httpd.service</filename>
directly, since such changes would be lost over package
upgrades. Running <command>systemctl edit
httpd.service</command> or <command>systemctl edit
httpd.socket</command> as root will create a drop-in file (in
the former case, in
<filename>/etc/systemd/system/httpd.service.d</filename>) which
over-rides the system defaults.</para>
<para>For example, to set the <option>LD_LIBRARY_PATH</option>
environment variable for the daemon, run <command>systemctl edit
httpd.service</command> and enter:
<programlisting>[Service]
Environment=LD_LIBRARY_PATH=/opt/vendor/lib</programlisting></para>
</refsect2>
<refsect2>
<title>Starting the service at boot time</title>
<para>The httpd.service and httpd.socket units are
<emphasis>disabled</emphasis> by default. To start the httpd
service at boot time, run: <command>systemctl enable
httpd.service</command>. In the default configuration, the
httpd daemon will accept connections on port 80 (and, if mod_ssl
is installed, TLS connections on port 443) for any configured
IPv4 or IPv6 address.</para>
<para>If httpd is configured to depend on any specific IP
address (for example, with a "Listen" directive) which may only
become available during start-up, or if httpd depends on other
services (such as a database daemon), the service
<emphasis>must</emphasis> be configured to ensure correct
start-up ordering.</para>
<para>For example, to ensure httpd is only running after all
configured network interfaces are configured, create a drop-in
file (as described above) with the following section:
<programlisting>[Unit]
After=network-online.target
Wants=network-online.target</programlisting>
See <ulink
url="https://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/"/>
for more information on start-up ordering with systemd.</para>
</refsect2>
<refsect2>
<title>SSL/TLS certificate generation</title>
<para>The <command>httpd-init.service</command> unit is provided
with the mod_ssl package. This oneshot unit automatically
creates a TLS server certificate and key (using a generated
self-signed CA certificate and key) for testing purposes before
httpd is started. To inhibit certificate generation, use
<command>systemctl mask httpd-init.service</command> after
installing mod_ssl, and adjust the mod_ssl configuration to use
an appropriate certificate and key.</para>
</refsect2>
<refsect2>
<title>Reloading and stopping the service</title>
<para>When running <command>systemctl reload
httpd.service</command>, a <emphasis>graceful</emphasis>
restart is used, which sends a signal to the httpd parent
process to reload the configuration and re-open log files. Any
children with open connections at the time of reload will
terminate only once they have completed serving requests. This
prevents users of the server seeing errors (or potentially
losing data) due to the reload, but means some there is some
delay before any configuration changes take effect for all
users.</para>
<para>Similarly, a <emphasis>graceful stop</emphasis> is used
when <command>systemctl stop httpd.service</command> is run,
which terminates the server only once active connections have
been processed.</para>
<para>To "ungracefully" stop the server without waiting for
requests to complete, use <command>systemctl kill
--kill-who=main httpd</command>; similarly to "ungracefully"
reload the configuration, use <command>systemctl kill
--kill-who=main --signal=HUP httpd</command>.</para>
</refsect2>
<refsect2>
<title>Automated service restarts</title>
<para>System packages (including the httpd package itself) may
restart the httpd service automatically after packages are
upgraded, installed, or removed. This is done using the
<command>systemctl reload httpd.service</command>, which
produces a <emphasis>graceful</emphasis> restart by default as
described above.</para>
<para>To suppress automatic reloads entirely, create the file
<filename>/etc/sysconfig/httpd-disable-posttrans</filename>.</para>
</refsect2>
<refsect2>
<title>Changing the default MPM (Multi-Processing Module)</title>
<para>httpd offers a choice of multi-processing modules (MPMs),
which can be configured in
<filename>/etc/httpd/conf.modules.d/00-mpm.conf</filename>.
See
<citerefentry><refentrytitle>httpd.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>
for more information on changing the MPM.</para>
</refsect2>
<refsect2>
<title>systemd integration and mod_systemd</title>
<para>The httpd service uses the <option>notify</option> systemd
service type. The <literal>mod_systemd</literal> module must be
loaded (as in the default configuration) for this to work
correctly - the service will fail if this module is not
loaded. <literal>mod_systemd</literal> also makes worker and
request statistics available when running <command>systemctl status
httpd</command>. See
<citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>
for more information on systemd service types.</para>
</refsect2>
<refsect2>
<title>Security and SELinux</title>
<para>The default SELinux policy restricts the httpd service in
various ways. For example, the default policy limits the ports
to which httpd can bind (using the <literal>Listen</literal>
directive), which parts of the filesystem can be accessed, and
whether outgoing TCP connections are possible. Many of these
restrictions can be relaxed or adjusted by using
<command>semanage</command> to change booleans or other
types. See
<citerefentry><refentrytitle>httpd_selinux</refentrytitle><manvolnum>8</manvolnum></citerefentry>
for more information.</para>
<para>The httpd service enables <emphasis>PrivateTmp</emphasis>
by default. The <filename>/tmp</filename> and
<filename>/var/tmp</filename> directories available within the
httpd process (and CGI scripts, etc) are not shared by other
processes. See
<citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>
for more information.</para>
</refsect2>
<refsect2>
<title>Socket activation</title>
<para>Socket activation (see
<citerefentry><refentrytitle>systemd.socket</refentrytitle><manvolnum>5</manvolnum></citerefentry>
for more information) can be used with <command>httpd</command>
by enabling the <command>httpd.socket</command> unit. The
<command>httpd</command> listener configuration must exactly
match the <literal>ListenStream</literal> options configured for
the <command>httpd.socket</command> unit. The default
<command>httpd.socket</command> has a
<literal>ListenStream=80</literal> and, if mod_ssl is installed,
<literal>ListenStream=443</literal> by a drop-in file. If
additional <literal>Listen</literal> directives are added to the
httpd configuration, corresponding
<literal>ListenStream</literal> options should be added via
drop-in files, for example via <command>systemctl edit
httpd.socket</command>.</para>
<para>If using socket activation with httpd, only one listener
on any given TCP port is supported; a configuration with both
"<literal>Listen 127.0.0.1:80</literal>" and "<literal>Listen
192.168.1.2:80</literal>" will not work.</para>
</refsect2>
<refsect2>
<title>Instantiated services</title>
<para>The <command>httpd@.service</command> unit is an
instantiated template service. An instance of this unit will be
started using the configuration file
<filename>/etc/httpd/conf/INSTANCE.conf</filename>, where
<emphasis>INSTANCE</emphasis> is replaced with the instance
name. For example, <command>systemctl start
httpd@foobar.service</command> will start httpd using the
configuration file
<filename>/etc/httpd/conf/foobar.conf</filename>. The
<option>HTTPD_INSTANCE</option> environment variable is set to
the instance name by the unit and is available for use within
the configuration file.</para>
<para>To allow multiple instances of httpd to run
simultaneously, a number of configuration directives must be
changed, such as <command>PidFile</command> and
<command>DefaultRuntimeDir</command> to pick non-conflicting
paths, and <command>Listen</command> to choose different ports.
The example configuration file
<filename>/usr/share/doc/httpd/instance.conf</filename>
demonstrates how to make such changes using
<option>HTTPD_INSTANCE</option> variable.</para>
<para>It can be useful to configure instances of
<command>httpd@.service</command> to reload when
<command>httpd.service</command> is reloaded; for example,
<command>logrotate</command> will reload only
<command>httpd.service</command> when logs are rotated. If this
behaviour is required, create a drop-in file for the instance as
follows:
<programlisting>[Unit]
ReloadPropagatedFrom=httpd.service</programlisting>
As with normal units, drop-in files for instances can be created
using <command>systemctl edit</command>, e.g. <command>systemctl edit
httpd@foobar.service</command>.</para>

# Note that no password is obtained from the user. Every entry in the user
# file needs this password: `xxj31ZMTZzkVA'.
# o ExportCertData:
# This exports two additional environment variables: SSL_CLIENT_CERT and
# SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
# server (always existing) and the client (only existing when client
# authentication is used). This can be used to import the certificates
# into CGI scripts.
# o StdEnvVars:
# This exports the standard SSL/TLS related `SSL_*' environment variables.
# Per default this exportation is switched off for performance reasons,
# because the extraction step is an expensive operation and is usually
# useless for serving static content. So one usually enables the
# exportation for CGI and SSI requests only.
# o StrictRequire:
# This denies access when "SSLRequireSSL" or "SSLRequire" applied even
# under a "Satisfy any" situation, i.e. when it applies access is denied
# and no other module can change it.
# o OptRenegotiate:
# This enables optimized SSL connection renegotiation handling when SSL
# directives are used in per-directory context.

# SSL Protocol Adjustments:
# The safe and default but still SSL/TLS standard compliant shutdown
# approach is that mod_ssl sends the close notify alert but doesn't wait for
# the close notify alert from client. When you need a different shutdown
# approach you can use one of the following variables:
# o ssl-unclean-shutdown:
# This forces an unclean shutdown when the connection is closed, i.e. no
# SSL close notify alert is sent or allowed to be received. This violates

# o ssl-accurate-shutdown:
# This forces an accurate shutdown when the connection is closed, i.e. a
# SSL close notify alert is sent and mod_ssl waits for the close notify
# alert of the client. This is 100% SSL/TLS standard compliant, but in
# practice often causes hanging connections with brain-dead browsers. Use
# this only for browsers where you know that their SSL implementation
# works correctly.
# Notice: Most problems of broken clients are also related to the HTTP
# keep-alive facility, so you usually additionally want to disable
# keep-alive for those clients, too. Use variable "nokeepalive" for this.
# Similarly, one has to force some clients to use HTTP/1.0 to workaround
# their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
# "force-response-1.0" for this.
