I attempted to restart Apache 2.2.14 (also using PHP 5.3.2 on Ubuntu 10.04, running all commands as root). It shutdown, but will not start back up. This is a brand new VPS with no Firewall or IP Table. When I run apache2ctl start
, I get this response:
(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
apache2ctl status
produces this:
Looking up localhost
Making HTTP connection to localhost
Alert!: Unable to connect to remote host.
lynx: Can't access startfile http://localhost/server-status
'www-browser -dump http://localhost:80/server-status' failed.
Maybe you need to install a package providing www-browser or you
need to adjust the APACHE_LYNX variable in /etc/apache2/envvars
lsof | grep http
returns nothing
netstat -plant

I am a Linux novice at best but everything else I saw asked for these reports. Nothing is blocking port 80 and yet Apache won't bind to it. Is the problem with Apache? I have Virtual Hosts set up but they are pretty straightforward and I have used the same configuration before. I can post .conf files if need be.
apache2ctl -t
: Syntac OK
service apache2 start
:

Assuming you're running apache as root (
service apache start
is better than manualapachectl
) because users can't bind privileged ports, please check you have no syntax errors:Then check your
NameServer
directive configuration and the resolving mechanism.Be sure your
NameServer myhost.example.com
refers to an address that can be resolved (check /etc/hosts or your DNS cache).
