<h3>Summary</h3>
|
||
|
||
<p>This module provides support for systemd integration. It allows
|
||
httpd to be used in a service with the systemd
|
||
<code>Type=notify</code> (see <a href="https://www.freedesktop.org/software/systemd/man/systemd.service.html">systemd.service(5)</a>
|
||
for more information). The module is activated if loaded.</p>
|
||
|
||
<div class="example"><h3>Example of systemd service unit (more settings are probably needed for production systems)</h3><pre>[Unit]
|
||
Description=The Apache HTTP Server
|
||
After=network.target
|
||
|
||
[Service]
|
||
Type=notify
|
||
ExecStart=/usr/local/apache2/bin/httpd -D FOREGROUND -k start
|
||
ExecReload=/usr/local/apache2/bin/httpd -k graceful
|
||
KillMode=mixed
|
||
|
||
[Install]
|
||
WantedBy=multi-user.target</pre></div>
|
||
|
||
<p>Special attention should be given to how <code>ExecStop</code>
|
||
and/or <code>KillMode</code> are configured for the service. If
|
||
configured, an <code>ExecStop</code> command should be a
|
||
<em>synchronous operation</em> which itself exits when the daemon
|
||
has terminated. Running <code>httpd -k stop</code>
|
||
<em>asynchronously</em> initiates daemon termination, so does not
|
||
satisfy this condition. The example above uses
|
||
<code>KillMode=mixed</code> so that systemd sends
|
||
<code>SIGTERM</code> to signal the parent process (and only the
|
||
parent) to shut down. The entire process group is then sent
|
||
<code>SIGKILL</code> after <code>TimeoutStopSec</code> elapses, if
|
||
any processes are still running. See <a href="https://www.freedesktop.org/software/systemd/man/systemd.kill.html">systemd.kill(5)</a>
|
||
for more information.</p>
|
||
|
||
<p>This module does not provide support for Systemd socket activation.</p>
|
||
|
||
<p><code class="directive"><a href="../mod/core.html#extendedstatus">ExtendedStatus</a></code> is
|
||
enabled by default if the module is loaded. If <code class="directive"><a href="../mod/core.html#extendedstatus">ExtendedStatus</a></code> is not disabled in
|
||
the configuration, run-time load and request statistics are made
|
||
available in the <code>systemctl status</code> output.</p>
|
||

|
||
<div id="quickview"><h3 class="directives">Directives</h3>
|
||
<p>This module provides no
|
||
directives.</p>
