Apache Troubleshooting Tips
When running Apache sometime we got problem. For example if you get a message that the browser can't connect to the server, first check to ensure the server is up. By run this command:
ps -aef | grep httpd
You should see a few httpd processes if Apache is up and running.
You didn't see any process, Try to restart Apache with:
sudo apachectl -k restart
You can also see the error log, with this command:
tail -f /usr/local/var/log/apache2/error_log
If that doesn't work, check to ensure you have Listen: 80 in your /usr/local/etc/apache2/2.4/httpd.conf configuration file.
You also can controll Apache with apachectl command:
$ sudo apachectl start
$ sudo apachectl stop
//The -k will force a restart immediately rather than asking politely to restart when apache is good and ready
$ sudo apachectl -k restart
