+ Socket activation
+
+ Socket activation (see
+ systemd.socket5
+ for more information) can be used with httpd
+ by enabling the httpd.socket unit. The
+ httpd listener configuration must exactly
+ match the ListenStream options configured for
+ the httpd.socket unit. The default
+ httpd.socket has a
+ ListenStream=80 and, if mod_ssl is installed,
+ ListenStream=443 by a drop-in file. If
+ additional Listen directives are added to the
+ httpd configuration, corresponding
+ ListenStream options should be added via
+ drop-in files, for example via systemctl edit
+ httpd.socket.
+
+ If using socket activation with httpd, only one listener
+ on any given TCP port is supported; a configuration with both
+ "Listen 127.0.0.1:80" and "Listen
+ 192.168.1.2:80" will not work.
