apache gives error

[niraj.vara]

Hi

Till the time apache was working fine. yesterday I was get the following error

httpd: apr_sockaddr_info_get() failed for xyz.com
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

I have edit the httpd.conf and add the ServerName xyz.com and its working fine.

but my question is why I was getting that error .........

till the time it was working I have not made any change in httpd.

Maybe you didn't change it but maybe an update did.

I had backuppc running fine on a Fedora machine but when it updated it seemed to break all configurations.

Apache gives this error message with the default configuration when the hostname of the server machine is not resolvable i.e. not bound to an IP address.

Some little experiment:

First I set my hostname to something what is not existing:
[root@rmu40 ]# hostname etwas.not.existg.com

... let's check it against DNS:
[root@rmu40 ]# host $(hostname)
Host etwas.not.existg.com not found: 3(NXDOMAIN)

Now apache throws these error message:
[root@rmu40 ]# service httpd start
Starting httpd: httpd: apr_sockaddr_info_get() failed for etwas.not.existg.com
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[ OK ]

After setting the hostname back to a resovable name, the error message at startup disappeared:

[root@rmu40 ]# service httpd start
Starting httpd: [ OK ]

It can also happen if DHCP/NetworkManager replaces a working resolv.conf file for one that doesn't refer to the previous working name server.
