How to assign custom domain to Azure VM

Posted on by tienductv
  • In Azure, create DNS Zone with custom domain name
  • Check name servers of above Zone, and copy them to Domains’s CPanel name servers
  • Add 2 DNS records to Zone (created in step 1) with IP points to Azure VM’s Public static IP as shown below
    • @
    • *
  • (Maybe this step is optional, need to check again!)
    Add CNAME severs in Domains’s CPanel with value = DNS of Azure VM
  • Change wp_options table in DB with 2 URL points to custom domain name correctly (if using WP site)
