Register and resolve a domain name - Simple Application Server

After building a website, you can directly access it through a public IP address, but we recommend that you configure a domain name for your website. This is to enhance security and convenience. This topic describes how to register and resolve a domain name to a simple application server, in the Simple Application Server console.

Procedure

(Optional) Step 1: Register a new domain name

Skip this step if you already have a domain name. Register a new domain name in the Simple Application Server console, or in the Alibaba Cloud Domain Name console. For more information, see Register a generic domain name.

Go to the Domain Name page in the Simple Application Server console.
This also can be done on the Domain Names tab of the instance details page.
Authorize the Simple Application Server service for the first time use.
In the pop up Tips dialog box, click OK to authorize.
Click Register New Domain Name. In the pop up Register New Domain Name dialog box, enter the domain name and suffix, and then click Search.
Note
If the domain name is already registered, you can either use a recommended domain name, or change to a different domain name or suffix.
Click Register Now, and complete the purchase. Select parameters such as subscription duration and domain name information template following the instructions.
Note
If you do not have a domain name information template, click Create , and fill in the domain name holder information. Then select it in the Registrant Profile section. For more information, see Create a domain name information template.
Return to the Simple Application Server console. In the Check whether you complete the payment for the domain name registration order dialog box, click Complete.
Add and resolve the domain name according to the guidance, or go to Step 2: Add and resolve a domain name.

Step 2: Add and resolve a domain name

Add a domain name to the Simple Application Server console for management, then resolve the domain name to the simple application server. This enables access to the website through the domain name.

On the Domain Name page, click Add Domain Names.

In the Add Domain Names dialog box, add and resolve the domain name following the instructions.
