   Required Duration	1 month	The minimum duration of a purchase is one month and the maximum duration is three years. Auto-renew is enabled by default, which means the purchased FlexusL instances will be automatically renewed before they expire.

Step 2: Configure a Security Group

Add inbound security group rules to ensure that the application preinstalled in the image can be accessed.

1. Log in to the console and click a resource card to go to the instance details page.
2. In the navigation pane on the left, choose Cloud Servers and then click the server name.

   

3. On the Security Groups tab, click Add Rule. In the displayed dialog box, add rules displayed in the following figure and click OK.

   The following figure only displays common rules. You can add more rules as needed.

   Table 1 Security group rules

   Priority	Action	Type	Protocol & Port	Source	Description
   100	Allow	IPv4	TCP: 9001	0.0.0.0/0	Allows external access to the application management page.
   100	Allow	IPv4	TCP: 9000	0.0.0.0/0	Allows external access to the application O&M dashboard.

(Optional) Step 3: Add and Resolve a Domain Name

Add and resolve a domain name for the server so that users can use the domain name to access the website. If the website is only used for personal development or testing, there is no need to add a domain name.

1. In the navigation pane on the left, choose Cloud Servers. Locate the server and click its name.
2. On the Server Details page, click the Domain Names tab and click Add Domain Name.

   Parameter	Setting
   Domain Name	Enter a domain name that will be added for the instance, for example, wpwebsite.com. NOTE: A domain name that is not registered can be added. After the domain name is added, it must be registered and licensed. To ensure that a domain name can be used normally, register the domain name and complete ICP licensing before adding the domain name.
   Enterprise Project	Select an enterprise project from the drop-down list. Enterprise projects are associated with public zones. You can manage public zones by enterprise project. NOTE: This parameter is displayed only when your account is an enterprise account.

3. Click OK.
4. In the row containing the wpwebsite.com domain name, click Configure Record Set.
   

   Parameter	Setting
   Domain Name Prefix	If you enter a prefix, a subdomain is used for website access. Either the domain name or its subdomains can be resolved to the EIP of the instance. Suppose the domain name is wpwebsite.com. If the domain name prefix is left empty, wpwebsite.com is resolved to the EIP. If the domain name prefix is www, the subdomain www.wpwebsite.com is mapped to the EIP.
   EIP	The EIP bound to the instance is displayed here automatically.

5. On the Domain Names tab, view the domain name resolution details.
6. Apply for ICP licensing for the domain name.

   To successfully access the server using a domain name, you must file the domain name. Domain name filing in the Huawei Cloud ICP license center is free of charge. For details, see ICP Filing Process.
