Add a domain name to Alibaba Cloud CDN

Procedure

1. Log on to the Alibaba Cloud CDN console.
2. In the left-side navigation pane, click Domain Names.
3. On the Domain Names page, click Add Domain Name.
4. Set the following parameters: Domain Name to Accelerate, Business Type, Origin Info, Port, and Region.
   

   The following table lists the parameters that you must set on the Add Domain Name page.

   Parameter	Option	Description
   Domain Name to Accelerate	-	Enter the domain name that you want to accelerate, for example, example.com. Take note of the following rules: You can use a specific domain name or a wildcard domain name as the domain name to be accelerated, for example, cdntest.example.com. Wildcard domain names are supported but Chinese domain names are not supported. Enter wildcard domain names in the specified format, for example, *.example.com. You cannot add a duplicate domain name to Alibaba Cloud CDN. If a DomainAlreadyExist error occurs, check whether the domain name is already added to other Alibaba Cloud services such as ApsaraVideo VOD, ApsaraVideo Live, Dynamic Route for CDN (DCDN), Secure CDN (SCDN), and Video Surveillance. You can also submit a ticket to fix this issue. You can add a maximum of 50 domain names to Alibaba Cloud CDN by using your Alibaba Cloud account. If the average daily peak bandwidth value exceeds 50 Mbit/s and your workloads are under protection, you can submit a ticket to add more domain names to Alibaba Cloud CDN. Content that is delivered from the domain name must comply with the limits of Alibaba Cloud CDN. For more information, see Limits. Note The specified wildcard domain names and the domain names that match the wildcard domain names must belong to the same Alibaba Cloud account. When you add a domain name to Alibaba Cloud CDN, Alibaba Cloud CDN verifies the ownership of the domain name. If the specified wildcard domain name and the domain names that match the wildcard domain name belong to different Alibaba Cloud accounts, an error message is returned. To request technical support from Alibaba Cloud, submit a ticket.
   Business Type	Image and Small File	If you want to accelerate the delivery of small-sized static content on your website, we recommend that you select Image and Small File from the Business Type drop-down list. Examples of small-sized static content include small-sized files, images, and style sheets.
   	Delivery of large files	If you want to accelerate the delivery of static files larger than 20 MB, we recommend that you select Large File Download from the Business Type drop-down list. Examples of large-sized static files include game installation packages, app update packages, mobile read-only memory (ROM) upgrade packages, and app packages.
   	VOD	If you want to accelerate the delivery of on-demand video or audio content, we recommend that you select VOD from the Business Type drop-down list.
   	DCDN	If your website or application contains large amounts of dynamic content, you can select DCDN from the Business Type drop-down list. After simple configurations, DCDN can separately accelerate the delivery of dynamic and static content. Static content is cached on CDN nodes. Dynamic content is retrieved from the origin server based on the optimal link algorithm and protocol layer optimization of Alibaba Cloud. After you select DCDN, you are prompted to go to the DCDN console. You can then add and configure the domain name. For more information, see Add a domain name.
   Origin Info	IP	You can enter the public IP addresses of one or more servers. IP addresses of Alibaba Cloud Elastic Compute Service (ECS) instances do not need to be reviewed.
   	Site Domain	You can enter the domain names of one or more origin servers. Note The specified domain name of the origin server cannot be the same as the domain name to be accelerated. Otherwise, a DNS resolution loop occurs and requests cannot be redirected to the origin server. For example, if the domain name of your origin server is img.yourdomain.com, you can set the domain name to be accelerated to cdn.yourdomain.com.
   	OSS Domain	You can enter the public endpoint of an Alibaba Cloud Object Storage Service (OSS) bucket, for example, xxx.oss-cn-hangzhou.aliyuncs.com. To view the public endpoint of an OSS bucket, go to the OSS console. You can also select the endpoint of an OSS bucket that belongs to the current Alibaba Cloud account from the Domain Name drop-down list. Internal endpoints of OSS buckets are not supported.
   	Function Compute Domain	You must set the Region and Domain Name parameters for the Function Compute domain name. For more information, see Set a Function Compute domain name.
   Port	-	Select a port based on your business requirements. Port 80 Requests are redirected to the origin server through port 80. Port 443 Requests are redirected to the origin server through port 443.
   Region	Global (Excluding Mainland China)	If you select Global (Excluding Mainland China), you do not need to apply for an Internet Content Provider (ICP) number for the domain name.
   	Global	If you select Global, you must apply for an ICP number for the domain name. For more information, see Apply for an Internet Content Provider (ICP) number for an accelerated domain name.
   	Mainland China Only	If you select Mainland China Only, you must apply for an ICP number for the domain name. For more information, see Apply for an Internet Content Provider (ICP) number for an accelerated domain name.

5. Click Next.
   

   After your domain name passes the review, you can view the domain name on the Domain Names page in the Alibaba Cloud CDN console. If the status of the domain name is Enabled, it indicates that the domain name has been added to Alibaba Cloud CDN.

   Note

   • You can submit a ticket to expedite the review.
   • If the origin server is an ECS instance or an OSS bucket, it takes less time to verify the ownership of the domain name.
   • After a domain name is added to Alibaba Cloud CDN, Alibaba Cloud CDN assigns a canonical name (CNAME) to the domain name. The Alibaba Cloud CDN service takes effect only after you add the CNAME record for the domain name.
