My web content is hosted by a different company than my DNS records/domains. Let's call the first content host and the second domain host.
The content hoster uses Plesk (v12 on CentOS 7).
I also got a domain there, but I don't want to use it. Let's call this one something.example
My "real" domain at the domain provider is called realthing.example
.
Up until now my working setup looked like this:
sub1.realthing.example
pointed via A-record to IP-Address of something.example
. That works.
sub2.something.example
has content and is working (content is showing in a browser)
What I want to do now:
sub3.realthing.example
point to sub2.something.example
and then show the content of sub2.something.example
.
I tried to do this with a CNAME entry but what happens is, that sub3.realthing.example
shows the content of something.example
.
Checking the reverse-DNS record with dnswatch.info shows the right setup (sub3.realthing.example
CNAME sub2.something.example
). So it seems that I need to do this at the content provider side to enable Apache to present the correct content. But I don't know how to do this with plesk.
Old post (same meaning):
my domain there is some internal URL (11-43-223-33.customer.company.example
). I configured my real domain (mydomain.example
) at my domain/dns provider to point to the IP-address (11.43.223.33
) of the content server. That works.
Now what I want to do and until now am not able to accomplish:
Using a subdomain (sub.mydomain.example
) to point to a subdomain at my contenthoster (sub.11-43-223-33.customer.company.example
). I used a CNAME entry for that (sub.mydomain.example
CNAME sub.11-43-223-33.customer.company.example
).
Instead of showing the content of sub.11-43-223-33.customer.company.example
when opening sub.mydomain.example
in a browser I got presented with the content of mydomain.example
.
As commented below, there is content behind sub.11-43-223-33.customer.company.example
which I can access if I open that URL in a browser. So the subdomain at my content provider is up and running by itself.
Is it even possible to accomplish this with Plesk? Do I need to add sth to the Apache config so that it'll work?
sub.11-43-223-33.customer.company.example
is up and running, I can open it with that URL in any browser. Only won't work with the CNAMEsub.mydomain.example
.. that will open the website ofmydomain.example
instead. I appended that explanation to the topic, thanks.mydomain.example
to the IP-address and now I wish to use a subdomain under the same IP-address. There is no way for the webserver to know that I want to open the subdomain when I just let DNS resolve to the IP address. So I thought "hey, CNAME is the way to go". Perhaps it is just not possible to access a subdomain with another DNS-entry Or I have to use some feature of Apache instead of meddling with DNS?example.com
and another forsub-domain.example.com
. Otherwise, Apache will not be able to match the request in the request header to a location and often provides the first site defined. Depending upon the OS, Apache will install differently. For example, Redhat will be different than Ubuntu. Using a control panel should make this transparent if you use one. What OS do you have? Are you using a control panel?
