[users@httpd] httpd process
hi all,
i just installed apache on centos 5 and have it automatically start up
when boot:
chkconfig httpd on

httpd
why do i have so many httpd services running?
i can't access to it (http://10.0.0.160), how do i troubleshoot this
problem?
less /etc/httpd/logs/access_log is empty.
less /etc/httpd/logs/error_log and i got:

Again, you need to check from the local machine. If you don't have a
browser, you can do
telnet 127.0.0.1 80
GET / HTTP/1.0
then press enter twice.
If that works, it confirms it is a network problem and not an apache
config problem.

10.0.0.160 & 10.0.0.128.

No, that wasn't your problem. When "UseCanonicalName off" is set
(which is typically the default) ServerName doesn't do anything. And
even when it does something, it wouldn't prevent you from connecting
to the server.

If you are completely lost, you should consider buying a book to get started:
http://opensource.atlassian.com/confluence/oss/display/BOOKS/Books+on+Apache+HTTP+Server+%28httpd%29
But if you want to go at it yourself, it's not a bad idea to go
through each directive in httpd.conf and look it up in the list here:
http://httpd.apache.org/docs/2.2/mod/directives.html
to figure out what it does.

i found the problem in /etc/httpd/conf/httpd.conf
#ServerName www.example.com:80
should be:
ServerName 10.0.0.160:80
ServerName dev.jss.com:80
however, i just overwhelming with so many directives in this file. any
advice on how to understand one by one. it's just so much i don't know
where to start. i assume the link at the very beginning of the file is
place to start.
i'm kinda newbie on this stuff. i'm setup this box for development, but

What is the exact text that appears in the browser? (I'm guessing it
is the standard network failure error message, but I want be sure.)

The most likely explanations for not being able to access a running
server have nothing to do with apache configuration. I would check the
Listen directive just to be sure. But the problem is more likely to
lie with your firewall (either internal to linux or a separate network
firewall) or with other network configuration settings.

What happens when you try to access that URL? Where are you accessing
it from? What happens if you try to access http://127.0.0.1/ from the
server? What does the Listen directive in httpd.conf look like?
