Recently i made a few changes to my CentOS VPS (installed DNS, a few certificates and change some chmod permissions). Everything seemed to have worked well.
However when I rebooted the server the httpd service didn't start. When i try to start it manually I get the following error.
-bash-3.2# /etc/init.d/httpd start
Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
