According to the bnsupport tool, it should exists under the
/opt/bitnami/apache2/bin directory. Could you check it? Could you also try to run it without sudo?
-rw-r--r-- 1 bitnami daemon 3483 Jul 5 2018 apachectl
It looks like execution permissions are missing. Did you modify them? You will need to give it execution permissions before running it
sudo chmod +x /opt/bitnami/apache2/bin/apachectl
Apart from that, could you tell us if you find any error when restarting services? What is the ouput of running the next commands?
sudo ps aux | grep -i bitnami
sudo netstat -tupln | grep "80\|443"
sudo /opt/bitnami/ctlscript.sh status
