Apache Problem, NEED HELP!

adnonimape · 03-16-2006, 09:19 PM

Ok, I am learning linux, and I wanted to run a network website, and perhaps one for online.

Apache wouldnt start at first, because of a couple of errors in the httpd.conf file, and i corrected those, and I am now stumped as what to do.

I am fairly new to linux, and I would like to learn more, which is why im here, and 'fooling' around with linux.

I am using CentOS 4.2.

This is the error i get when doing ./httpd restart

Starting httpd: [Thu Mar 16 22:11:43 2006] [error] (EAI 2)Name or service not known: Failed to resolve server name for 192.168.1.100 (check DNS) -- or specify an explicit ServerName
[ OK ]

I do not know where to look, or what to look at, what to adjust, or do. Please help! =)

Thank you!

I assume that you have a domain name that you want people to type into their browser to see your web site. Is that domain name registered in DNS and does it point to your web server (and does your web server use the same DNS)?

If your domain name is www.somedomain.com, what happens when you type the following from a terminal window on the web server:

Code:

ping www.somedomain.com

No, I don't have a domain for it. It's just a network computer. The ip of it is 192.168.1.105. If I ping my computer from it, i get .277ms. So it is on the network, and recognizes it. It just gives me that error.

I've run apache off of windows before, and I got it to work fine just by typing http://x.x.x.x I didn't need to have a domain for it.

As the error message suggest, you'll need a hostname (either looked up via DNS or in /etc/hosts) that matches your IP address or a ServerName directive in httpd.conf (to "force" the server name into something else than you're host's real name).

adnonimape · 03-17-2006, 10:55 AM

The directory /etc/hosts/ doesn't exist.

Also, I don't really get what you're saying (I am fairly new to linux, and apache), but im learning =)

Thanks for your help!

Since you're using an IP address to access the web server instead of a domain name, I'd say the easiest ways to stop that error are:

1. Add an entry to your /etc/hosts file for your IP address so that Apache can determine a server name for itself. For example:

Code:

127.0.0.1      localhost.localdomain    localhost
192.168.1.105  somehost.somedomain.com  somehost

or

2. Uncomment the ServerName in httpd.conf and give it a server name.

Neither of these methods will make the web server available by name (well, the first one might if you add the name to your other PCs hosts files) but it should make the error go away.

Ok, thank you. That got rid of all the errors when stopping/starting apache. But I still cannot access it via a web browser. I try 192.168.1.105:8080 and it seems to not work. I have the httpd.conf file set to listen on port 8080 as well. But it still does not seem to work. From any network computer.

Do you get any messages in the browser when you try to access your web server? Also, check the error_log for any messages.

Peace...

This is the last entries in the error_log, from my last restart that outputted no errors. In my browser, I just get a Page Cannot Be Found thing. Here is the error_log:

Ok, run this command to confirm Apache is listening on the port you think it is:

$ netstat -a | grep 8080

Peace...

adnonimape · 03-17-2006, 05:55 PM

I did that, and I got no output, It just went to the next line as if I had just pressed 'Enter'

tomdkat · 03-17-2006, 06:16 PM

Ok, that means Apache is NOT listening on port 8080. Run this command:

$ netstat -a | more

and see if you can find a reference to port 80 or "http". Also, look in the httpd.conf file to see what port Apache is configured to listen on.

Peace...

adnonimape · 03-17-2006, 10:16 PM

There was no reference to http, and httpd.conf is configured to listen on

Code:

*:8080

I don't see what the problem could be, I don't know why netstat isn't showing that..

Are you running a firewall. If so you need to enter apache into
the firewall. How you do this depends upon your linux
distribution.

adnonimape · 03-17-2006, 11:00 PM

Its CentOS 4.2, and I think when I was installing it, I chose for it to install the firewall, how would I go about removing, or disabling it?

I can access http://192.168.1.105:8080 from the machine the webserver is on, but from other network computers, I cannot.
