Figure 1 Process of quickly purchasing and configuring a CBH instance

Preparations

Before making a purchase, you need to sign up for a HUAWEI ID, enable Huawei Cloud services, complete real-name authentication, and top up your account. Ensure that your account has sufficient or has a valid payment method configured.

Step 1: Buy a Bastion Host

1. Log in to the management console.
2. Click in the upper left corner of the page, select a region, and choose Security & Compliance > Cloud Bastion Host to go to the CBH instance management console.
3. Click Buy CBH Instance to go to the Buy CBH Instance page.
4. Select CBH Instance for Service Type and specify other parameters as required. For more information, see Table 2.

   Table 2 Parameters for purchasing a CBH instance

   Parameter	Example Value	Description
   Billing Mode	Yearly/Monthly	The billing mode of the instance. You can select Yearly/Monthly or Pay-per-use. Yearly/Monthly is a prepaid billing mode in which a CBH instance is billed based on the service duration. This cost-effective mode is ideal when the duration of CBH instance usage is predictable. Pay-per-use billing is a postpaid mode in which you pay for what you use by the hour. NOTE: After the pay-per-use billing mode is enabled, the billing stops only when the target instance is deleted, regardless of the instance running status.
   Region	CN East-Shanghai1	Select the region where the bastion host is used. You are advised to select the region where you deploy ECSs and RDS database instances you want to manage. This can reduce network latency and improve access speed.
   Instance Type	Single-node	Select a single-node or primary/standby instance type based on your service requirements. Single-node: Only one bastion host is available after the purchase. Primary/Standby: After the purchase, two bastion hosts are delivered to form a two-node cluster. If the primary bastion host is unavailable, the standby one takes over the job immediately. NOTE: If you buy a primary/standby instance, do not disable HA, or logins will fail.
   AZ	Retain the default value.	An AZ is the location where the purchased bastion host is deployed. NOTE: If you buy an primary/standby instance, two bastion hosts will be deployed in different AZs. So, you need to select the primary and standby AZs. You can retain the default settings.
   Instance Name	CBH-shanghai-01	Name of the CBH instance.
   Specifications	10 Assets	Specifications of your CBH instance. CBH specifications: 10, 20, 50, 100, 200, 500, 1,000, 2,000, 5,000, and 10,000 assets. CBH provides the standard and professional editions. Each edition has 50, 100, 200, 500, 1,000, 2,000, 5,000, and 10,000 asset specifications. Asset quantity indicates the maximum number of resources your instance can manage and the maximum number of concurrent requests your instance supports. The vCPUs and the size of data and system disks vary depending on the asset quantity.. For example, if you select 100 assets, the number of resources your instance can manage and the maximum number of concurrent connections your instance supports are both 100.
   Edition	Standard	CBH provides standard and professional editions. The professional edition can manage database resources.
   Storage Package	0	If you need more storage for a CBH instance, you can buy a storage package..
   VPC	vpc-default(192.168.x.x/xx)	The Virtual Private Cloud (VPC) where your instance is located. Select a VPC in the current region. If no VPC is available in the current region, click View VPC and create one. NOTE: By default, networks in VPCs in different regions or even in the same region are not connected. Different networks are isolated from each other. This is not the case for different AZs in the same VPC. Two networks on the same VPC should be able to communicate with each other even if they are in different AZs. CBH can directly access and manage resources, such as ECSs, in the same VPC in the same region. To manage resources such as ECSs in different VPCs in the same region, establish a VPC peering connection or use a VPN to connect networks. For details, see Creating a VPC Peering Connection. Managing ECSs across regions is not recommended. For more details, see VPC Planning.
   Assign IPv4 Address	Auto	Select Auto or Manual. If you select Manual, you can view the used IP addresses.
   Security Group	Sys-default	The security group for your CBH instance. The default security group is Sys-default in the current region. If no security group is available, click Manage Security Groups to create a security group or configure a new one. NOTE: A security group provides access rules for the CBH instances and resources that have the same security protection requirements and are mutually trusted in the same VPC. CBH instances are protected by these access rules after being added to the security group. For details, see Security Group Overview. CBH instances and ECSs can be added to the same security groups. They do not affect each other when implementing security group rules. Before creating HA instances, ensure that the security group allows inbound traffic from ports 22, 31036, 31679, and 31873. When a bastion host instance is created, ports 80, 8080, 443, and 2222 are automatically enabled. If you do not need to use them, disable them immediately after the instance is created. During cross-version upgrade, ports 22, 31036, 31679, and 31873 are automatically enabled for the instance. After the upgrade, keep port 31679 enabled and disable other ports immediately if you do not need to use them. For more details about security groups, see How Do I Configure a Security Group for a CBH Instance?
   EIP	100.x.x.x	(Optional) Select an EIP in the current region. If no EIP is available in the current region, click Buy EIP to create one.
   Enterprise Project	default	Select the enterprise project the CBH instance belongs to. The default enterprise project is selected by default.
   Password	Cbh@shanghai.10	User-defined password of the admin user. NOTE: The password must: Contain 8 to 32 characters. Contain at least three of the following types of characters: uppercase letters (A to Z), lowercase letters (a to z), digits (0 to 9), and following special characters: !@$%^-_=+[{}]:,./?~#* Cannot contain the username or the username spelled backwards. Cannot contain more than two consecutive identical characters. Enter the same password in the Password and Confirm Password text boxes. The CBH system cannot obtain the password of system administrator admin. Keep your account information secure. When you log in to your CBH system as admin for the first time, change the password and configure mobile phone number as prompted. Otherwise, you cannot log in to the CBH system. If you forget the password of user admin after a CBH instance is purchased, you can reset the password.
   Required Duration	1 month	Required duration of the instance. You can buy a CBH instance on a monthly or yearly basis.

5. Confirm details in the Current Configuration area and click Next.
   

   When receiving a network restriction notification, click Enable to eliminate the network restrictions so that the instance can be issued after purchase.

   You can view the rules in the security group and firewall ACL and ensure that:

   • Access to port 9443 is allowed in the outbound direction of the security group to which your CBH instance belongs.
   • The subnet where the instance locates is not associated with the firewall ACL, or the ACL rule of the associated firewall allows the instance to access port 9443 in the outbound direction.

6. On the Confirm page, confirm the details, read the privacy statement, select Privacy Statement, and click Submit.
7. Make your purchase and return to the CBH console. Check the newly purchased instance in the CBH instance list.

   After a CBH instance is purchased, a mapped CBH system is automatically created for you, which takes about 10 minutes.

   

   Do not unbind an EIP from a CBH instance before the mapped CBH system is created. If you unbind an EIP from an instance before its status changes to Running, the mapped CBH system may fail to be created.

Step 2: Log In to the Bastion Host

You need to log in to the instance to perform operations such as bastion host management, O&M, and audit.

1. Return to the CBH instance list page and check whether the status of the purchased CBH instance is Running.
2. Click Remote Login in the Operation column. In the displayed dialog box, click Log In in the Admin Login bar to automatically log in to the bastion host.
   

   You need to change the initial password of the admin user upon the first login to access the bastion host instance.
