Apache restart on Ubuntu - error "could not bind to address 0.0.0.0.80"

I'm a n00b - trying to get apache2 set up on Ubuntu 9.10 (Karmic Koala) on Rackspace Cloud. I have set up/config开发者_StackOverflowured OpenSSL and installed Apache, but Apache won't start. I assume its a misconfiguration in my /etc/apache2/sites-available/ssl or /etc/apache2/sites-available/default files)

When I try to restart apache using the command:

sudo /etc/init.d/apache2 restart

I get the following error message:

[error] (EAI 2)Name or service not known: Could not resolve host name *.80 -- ignoring! [error] (EAI 2)Name or service not known: Could not resolve host name *.80 -- ignoring! (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs ...fail!

For my /etc/apache2/sites-available/ssl I have used a virtual host of *:443.

For my /etc/apache2/sites-available/default i have used a virtual host of *:80

Turn off Skype. It's use port number 80 for incoming messages. Eventually check what use this port at the moment using netstat.

Second resolve is simply: Add ServerName localhost to main config. file.

1. Check /etc/hosts. Be sure that your machine name and localhost domain definition is correct (ie: "127.0.0.1 localhost.localdomain localhost"
2. However it is highly unlikely, check /etc/apache2/ports.conf if it contains explicitly "0.0.0.0"
