A problem with apache installation http://localhost issue

Hello perl fellows:

I encountered a problem when I was installing a perl
module. The httpd server related module was hanging
overnight when it was trying to test
http://localhost:XXXXX...

Today, I tested with my httpd server installation.
I found that I can view the webpage after I started
httpd server through the actually ip address. I have
configured my ip address under /etc/hosts.

However, I couldn't view the webpage through
http://127.0.0.0/ or http://localhost/

It looks bizzare to me, if I can't view it through
http://localhost, then I couldn't install the httpd
related perlmodules because they require the testing.

Thanks for your help!

Check that the entry

127.0.0.1 localhost

is present.

Apache only listens on IPs and Ports that are configured in the httpd.conf.
Yours seems not to be configured to listen on 127.0.0.1, you can check that by

$ netstat -neatp

Depending on your apache configuration, a

Listen 127.0.0.1:80

in the httpd.conf may be sufficient.

Check that the entry
127.0.0.1 localhost
is present.

How to check the this entry? I added this entry to
httpd.conf and listen 127.0.0.1:80. However, I got the
error message. Do you have any other ideas?

I also checked. I am convinced that I didn't have
that configured in httpd.conf. How could I do that?
