<title>Description</title>
<para><command>apachectl</command> is a front end to the Apache HyperText
Transfer Protocol (HTTP) server. It is designed to help the
administrator control the functioning of the Apache
<command>httpd</command> daemon.</para>
<para>The <command>apachectl</command> script takes one-word arguments like
<option>start</option>,
<option>restart</option>, and
<option>stop</option>, and translates them
into appropriate signals to <command>httpd</command>.</para>
<para>The <command>apachectl</command> script returns a 0 exit value on
success, and &gt;0 if an error occurs.</para>
<refsect2 id="compatibility">
<title>Compatibility</title>
<para>The version of <command>apachectl</command> used on this
system is a replacement script intended to be mostly (but not
completely) compatible with version provided with
<emphasis>Apache httpd</emphasis>. This
<command>apachectl</command> mostly acts as a wrapper around
<command>systemctl</command> and manipulates the
<command>systemd</command> service for <command>httpd</command>.
The interface to the <emphasis>Apache</emphasis> version of
<command>apachectl</command> is described at <ulink
url="https://httpd.apache.org/docs/2.4/programs/apachectl.html"/>.</para>
<para>The following differences are present in the version of
<command>apachectl</command> present on this system:
<itemizedlist>
<listitem><para>Option arguments passed when starting
<command>httpd</command> are not allowed. These should be
configured in the systemd service directly (see <citerefentry><refentrytitle>httpd.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>).</para></listitem>
<listitem><para>The <command>"fullstatus"</command> option is
not available.</para></listitem>
<listitem><para>The <command>"status"</command> option does
not use or rely on the running server's
<emphasis>server-status</emphasis> output.</para></listitem>

</refsect1>
<refsect1 id='options'>
<title>Options</title>
<variablelist remap='TP'>
<varlistentry>
<term><option>start</option></term>
<listitem>
<para>Start the Apache <command>httpd</command> daemon. Gives an error if it
is already running. This is equivalent to <command>systemctl start httpd.service</command>.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>stop</option></term>
<listitem>
<para>Stops the Apache <command>httpd</command> daemon. This is equivalent to
<command>systemctl stop httpd.service</command>.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>restart</option></term>
<listitem>
<para>Restarts the Apache <command>httpd</command> daemon. If the daemon is
not running, it is started. This is equivalent
to <command>systemctl restart httpd.service</command>.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>status</option></term>
<listitem>
<para>Displays a brief status report. This is equivalent to <command>systemctl status httpd.service.</command></para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>graceful</option></term>
<listitem>
<para>Gracefully restarts the Apache <command>httpd</command> daemon. If the
daemon is not running, it is started. This differs from a normal
restart in that currently open connections are not aborted. A side
effect is that old log files will not be closed immediately. This
means that if used in a log rotation script, a substantial delay may
be necessary to ensure that the old log files are closed before
processing them. This is equivalent to
<command>systemctl kill --signal=SIGUSR1 --kill-who=main httpd.service</command>.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>graceful-stop</option></term>
<listitem>
<para>Gracefully stops the Apache <command>httpd</command> daemon.
This differs from a normal stop in that currently open connections are not
aborted. A side effect is that old log files will not be closed immediately.
This is equivalent to
<command>systemctl kill --signal=SIGWINCH --kill-who=main httpd.service</command>.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>configtest</option></term>
<listitem>
<para>Run a configuration file syntax test. It parses the configuration
files and either reports <literal>Syntax OK</literal>
or detailed information about the particular syntax error. This is
equivalent to <command>httpd -t</command>.</para>
