Apache Address already in use: make_sock: could not bind to port 80 or 443

First make sure port 80/443 is not used by any other service or application with netstat command: # netstat -tulpn| grep :80 If port 80 is bind to httpd, kill all process: # killall -9 httpd Now start the httpd: # /etc/init.d/httpd start Also make sure you are root while starting the httpd.
