Configure custom domains (Domain CNAMEs).

After initializing the CDN, the system provides a CDN domain in the format {slug}.cdn.vccloud.vn for integration into your website or application. To use your own domain name instead of the provided CDN domain, please follow these steps:

Step 1: Go to the “Domain customization” page > enter the private domain name you want to use instead of the CDN domain > Click “Create”.

Step 2: Verify custom domain

• Verify by pointing the DNS CNAME to the CDN domain.

  • Log in to your private domain management page and point the DNS CNAME record to the provided CDN domain. For example:

    Record	Name/Host/Alias	Value	Time to Live (TTL)
    CNAME	cdn	huylvt.cdn.vccloud.vn	300

  • Check if the custom domain has been pointed to the CDN domain

    $ dig +noall +answer cdn.longnt.store
    cdn.longnt.store.       300     IN      CNAME   longnt.cdn.vccloud.vn.
    longnt.cdn.vccloud.vn.  150     IN      A       222.255.27.187
    longnt.cdn.vccloud.vn.  150     IN      A       222.255.27.184
    longnt.cdn.vccloud.vn.  150     IN      A       123.30.242.10
    longnt.cdn.vccloud.vn.  150     IN      A       222.255.27.45
    longnt.cdn.vccloud.vn.  150     IN      A       123.30.242.13
    

  • Click button “Verify”

• Verify by uploading a .html file to the origin.

  • Download the verification file (.html) from the CDN provider’s website.
  • Upload the downloaded .html file to the root directory of your website.
  • Access the verification link using a web browser or the curl command to check if it’s working.

    $ curl http://cdn.huylvt.com/bizflycloudbdfcf1c61a583edfa9c97296da7eec41.html
    BizflyCloud Verify: bdfcf1c61a583edfa9c97296da7eec41
    

  • Click button “Verify”

Step 3: You can check if your custom domain is working correctly on the CDN system by setting up a host file entry.

$ cat /etc/hosts
123.30.242.10 cdn.huylvt.com

Step 4: Configure SSL (in case HTTPS protocol is used).
