Subject Re: [users@httpd] VirtualHost configuration not working as expected with ePages solution

Hi Adam

Thanks for your reply. 

Yes, I did c/p and then replace the domains with the placeholders.

I too noticed that there wasnt any entry for url1.mydomain.com, and I have been down the same
process you advised of starting with one working and gradually adding.

So I start off with httpd.conf and the relevant lines are:

NameVirtualHost *:80
>
>
>Include conf.d/*.conf
>
>
><IfDefine PROXY>
><VirtualHost *:80>
>ServerName url1.mydomain.com
>ServerAlias surl1.mydomain.com
><Location /epages/>
>    <IfDefine LB>
>        ProxyPass balancer://cluster/epages/
>        ProxyPassReverse balancer://cluster/epages/
>    </IfDefine>
>    <IfDefine !LB>
>        ProxyPass xxxxxxxxxxxxxxxxxxxxxxx
>        ProxyPassReverse  xxxxxxxxxxxxxxx
>    </IfDefine>
></Location>
></VirtualHost>
></IfDefine>
>
>Only the first VirtualHost is specified. apachectl -t -D DUMP_VHOSTS produces:

VirtualHost configuration:
>127.0.0.1:443          localhost (/etc/httpd/conf.d/ssl.conf:81)
>Syntax OK
>
>So, again, as you mentioned, Apache doesnt know what to do with url1.mydomain.com. Is
this because the VirtualHost definition is enclosed within an IfDefine?

But navigating to url1.mydomain.com brings up my epages website (which is correct). 

So then I go and add in a second VirtualHost

<VitualHost *:80>
>
>
>DocumentRoot /var/www/html/myroot
>ServerName url2.mydomain.com
>ServerAlias url2.mydomain.com
></VirtualHost>

>and the DUMP_VHOSTS output is:

VirtualHost configuration:
>127.0.0.1:443          localhost (/etc/httpd/conf.d/ssl.conf:81)

>*:80                   is a NameVirtualHost

>         port 80 namevhost url2.mydomain.com (/etc/httpd/conf/httpd.conf:998)
>Syntax OK

>So now Apache knows about url2, but still doesnt know about URL1.

And now, url1.mydomain.com and url2.mydomain.com both go to my second site, never epages.

Sorry for the long message, just trying to show the steps I've taken and the output at each
stage.

Thanks again for your help.

Tom

Tom,

Sorry for the belated reply.

I'm assuming you copy/pasted this out and replaced the real domains to 'protect the innocent'. 
But if you didn't flub copy/paste, I --do not-- see any indication that Apache knows what
to do or will do anything specific when a request comes in for 'url1.mydomain.com'.  If you
notice the output above, you will always default to 'url2.mydomain.com' for any HTTP request
coming in on that listening service on that IP address.  There isn't --any-- VirtualHost
reference to 'url1' listed.

I forgot what your VirtualHost containers looked like for both ur1 and ur2 domains, but I
think you definitely just take a isolation approach to it:  work with one, get it working
with it's own VirtualHost container, then add another vhost in and so on, then re-verify with
'apachectl -t -D DUMP_VHOSTS' and from a web browser.  From there once you get it nailed
down, then do any merging for maintenance sake on your .conf files.

Hope that helps.
