How to configure subdomains to use www and non-www

September 16, 2016 511 views
DNS CentOS

Hi, I have www.mysite.com and mysite.com working. I will be creating subdomains for this site on the same server such as
customer1.mysite.com

Now customer1.mysite.com is accessible. When I try www.customer1.mysite.com. I get dnsunresolvedhostname

I have a cname for www to mysite.com and tried to add cname "www" for customer1.mysite.com and it would not let me.
Please let me know what I have to add in dns to get both www and non-www to work with each subdomain I created.

Yes, as you said CNAME record www for customer1.mysite.com will report an error.
To make it working, you should be able to add CNAME record www.customer1 for mysite.com instead of www for customer1.mysite.com

There are two ways this is generally accomplished.

The first which is not possible completely on DigtialOcean would be to delegate the subdomain to another DNS server or zone and create a zone specifically for customer1.mysite.com. This is overkill for this need but would solve the problem.

The second and easier way to do this in the DigitalOcean control panel would be to create a CNAME record like this on your domain:

www.customer1 CNAME  customer1
