Apache2 service won't stop

I can start the server fine. The qualified domain name error is pretty common error when you first test apache. I'm having trouble stopping the service though.

using

apachectl stop
apachectl -k stop
apachectl graceful-stop
apachectl -k graceful-stop

does not kill the server.

~ $ apachectl stop
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName' directive globally to suppress this message
(20014)Internal error (specific information not available): AH00058: Error retrieving pid file var/run/apache2/httpd.pid
AH00059: Remove it before continuing if it is corrupted.

also killall and removing the pid file doesn't kill the server.

killall -9 httpd 
rm ${PREFIX}/var/run/apache2/httpd.pid

cleared cache in browser to double check after running kill commands and nothing happens. the process still runs in the background.

ps aux | grep httpd

also comes back up empty handed.

mlocate also comes up empty handed

whereis apache

this is not okay, especially if in a public network.

also there is no var/www/html as far as i can tell

find ${PREFIX} -type d -name 'www'

returns nothing.

server root is set to $PREFIX which leads to a dead end.

after poking around ${PREFIX}/etc/apache2/httpd.conf, i find document root is set to ${PREFIX}/share/apache2/default-site/htdocs which breaks convention, but considering termux doesn't have the standard heiarchy, this makes sense in a weird way. I would still have left it as ${PREFIX}/var/www, but its not a big deal.

After looking at the error log

I found no real helpful clues.

because apachectl is a wrapper for httpd, i looked at the shell script to see if there was anything special about it aside from config options which led to lynx (haven't looked at it yet though).

i decided to run the stop commands using httpd -k directly, but that didnt do anything either.

3. If program write it's own log files, you may need to attach them.

UPDATE: After some trial and error, ps aux returned the httpd PIDs and I was able to use kill -SIGINT {PID} to end the process.

Its still weird that ps aux didn't pick up on this until last minute though. Maybe something to do with the terminal session.

I created new terminal sessions to open files with less to check them out and on the last tty i decided to give a try again and this time it showed up.

After clearing the browser cache, I was able to verify that the httpd service had ended. I stil have no idea why the processes wouldn't show up after starting apache though.
