I've made multiple searches for e.g. "apache Sierra", but haven't been able to find my issue.
I have a MacBook Pro running OSX Sierra 10.12.13, and it seems to have some version of Apache installed, but I can't connect on port 80 (or 443), either with a browser, or by running
telnet localhost 80. If I run
apachectl restart, it runs without reported error; if I run
apachectl stop it runs without reported error; if I run
apachectl start when I think Apache is running, it gives an error message,
/System/Library/LaunchDaemons/org.apache.httpd.plist: service already loaded. A
which apachectl gives
/usr/sbin/apachectl, so I believe I'm running OSX's native Apache and not a version pulled in from Homebrew.
What can/should I be doing so that Apache is running normally?
