Cara Mengatasi Error Apache2 di GNU/Linux

Assalamualaikum Wr.Wb.
dengan diberikan nikmat dan rezeki dari Allah SWT, saya Mr.GagalTotal666
akan share bagaimana cara mengatasi error Apache2 saat di start
dan restart di linux/GNU Linux.

keluhan nya jika di restart :

root@ghostgtr666:~# /etc/init.d/apache2 restart
 * Restarting web server apache2

(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
AH00015: Unable to open logs
Action 'start' failed.
The Apache error log may have more information.
* The apache2 instance did not start within 20 seconds. 
Please read the log files to discover problems [Fail]

dan jika di start :

mrghostgtr666@ghostgtr666:~$ sudo /etc/init.d/apache2 start
 * Starting web server apache2
AH00558: apache2: Could not reliably determine the server's fully qualified domain name,
using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message

ikuti langkah berikut jika apache2

anda bermasalah seperti yang saya tunjukan di atas :

" $ echo "ServerName localhost" | sudo tee /etc/apache2/conf-available/fqdn.conf 
&& sudo a2enconf fqdn "

" $ sudo su " >> masuk mode root
" $ lighty-enable-mod cgi "
" $ lighty-enable-mod userdir "

" $ for i in `ps auwx | grep -i nobody | awk {'print $2'}`; do kill -9 $i; done "
" $ for i in `lsof -i :80 | grep http | awk {' print $2'}`; do kill -9 $i; done "
" $ for i in `lsof -i :80 | grep http | awk {' print $2'}`; do kill -9 $i; done "
" $ sudo killall -9 apache2 "
" $ sudo /etc/init.d/apache2 restart " atau " $ sudo service apache2 restart "

restart berhasil selanjut nya lakukan start :

" $ sudo service apache2 start "
" $ sudo service apache2 status "

setelah di cek " Apache2 is running " cek juga di browser :

" $ localhost " atau " $ 127.0.0.1 "

sekian tutorial nya semoga bermanfaat ^_^
