I installed Apache 2 on Ubuntu 12.10. When I try to start the service using
sudo /etc/init.d/apache2 start, I get the following message.
*Starting web server apache2 (98)Address already in use: make_sock: could not bind to address 127.0.0.1:80 no listening sockets available, shutting down Unable to open logs Action 'start' failed. The Apache error log may have more information. [fail]
