Apache refuses to connect to localhost

Hello!

I had Apache 2.0.50 compiled on my Fedora Core 2 box. It's just for running my PHP scripts and testing my homepage. Then I changed the config file and enabled viewing the local homepage to all on the LAN. This worked great too.
Then once it stoped running. I got always this message "The connection was refused when attempting to connect to localhost.". Tryed http://localhost/ , http://172.17.23.21/ [my IP adress].
I searched the forum for simmilar threads, I found some, but they didn't fix my problem.

So I recompiled my apache 2.0.52, but I still get this error. It's not working either on LAN nor on my local PC.

First, I'd like to say it's no firewall problem, port 80 is not blcked.
I made some changes to the httpd.conf file but it still won't connect.
I get this error when trying to start apache:

Code:

[root@space root]# /usr/local/Apache2/bin/apachectl start
httpd: Could not determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
(98)Address already in use: make_sock: could not bind to address 172.17.23.21:80
no listening sockets available, shutting down
Unable to open logs
[root@space root]#

So if I remove my IP adress from the "Listen" command I'll get this error:

Code:

[root@space root]# /usr/local/Apache2/bin/apachectl start
httpd: Could not determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[root@space root]#

This is the error_log file:

Code:

[root@space root]# cat /usr/local/Apache2/logs/error_log

"space" is my hostname.

What can I do?
Thank you for any help!

Regards, Boby!

You need ServerName in your httpd.conf. If you are to only access it from the localhost, naming it "localhost" will do just fine, but if others try to access it this way they will try to connect to their own computers when clicking links or loading images.

Also, do you have a functional hostname? If you type hostname you should get the name of the system. If not you need to set it (the file is /etc/hostname).

Also, the /etc/hosts file may be of interest if name lookup fails. If your computer is called "mybox" you can set up an alias like this:

Code:

127.0.0.1    localhost    royne

The other problem you have is that some other program is listening to tcp/80 it seems. lsof -i will tell you what process is listening to port 80.

Hello Håkan!

Thank you so far for your reply!
I am connected to a LAN and we have a given hostname from the server. Once I changed this in network config and set my hostname to "space" manually. You mentioned to look for my hostname so this ideea came to me. I deleted my manually added hostname and now it works when I type localhost

Thank you!
Everything is working fine, but the rest of the LAN cannot access my server. I edited the httpd.conf and wrote this:

Code:

# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)
#
#Listen 12.34.56.78:80

Listen 172.17.23.21:80
Listen 80

When someone of the LAN types my IP adress in the browser, it just searches and searches for the page. Before this problems it worked fine. So I think there is another problem with the config of my hostname.
These are my settings:

Code:

[boby@space boby]$ cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=

and

Code:

[boby@space boby]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain   localhost

So what else do I have to change so my local page can be viewed by other PC's in my LAN?

Thank you very much!
Boby
