Apache Module mod_systemd

Summary

This module provides support for systemd integration. It allows httpd to be used in a service with the systemd Type=notify (see systemd.service(5) for more information). The module is activated if loaded.

[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

Special attention should be given to how ExecStop and/or KillMode are configured for the service. If configured, an ExecStop command should be a synchronous operation which itself exits when the daemon has terminated. Running httpd -k stop asynchronously initiates daemon termination, so does not satisfy this condition. The example above uses KillMode=mixed so that systemd sends SIGTERM to signal the parent process (and only the parent) to shut down. The entire process group is then sent SIGKILL after TimeoutStopSec elapses, if any processes are still running. See systemd.kill(5) for more information.

This module does not provide support for Systemd socket activation.

ExtendedStatus is enabled by default if the module is loaded. If ExtendedStatus is not disabled in the configuration, run-time load and request statistics are made available in the systemctl status output.
