What mods can you put in clothing in 7 Days to Die?

An alternative approach might be to start apache via a script-call defined in inetd.conf.

This approach is detailed in the article Starting Lighttpd on demand, which although Lighttpd-oriented, might possibly be made to apply to your version of apache.

The article above contains the script for starting the Lighttpd web-server on reference to a given port, where lighttpd needs probably be substituted to apachectl. It also details some ideas on how it can also be automatically shut-down so it doesn't stay running forever.

If this approach is applicable to your case, you might consider adding your inetd.conf configuration-line and scripts to your post for future readers.
