Application Scenarios for Using Key Pairs

Key Pairs

Key pairs (SSH key pairs) are a set of security credentials for identity authentication when you remotely log in to ECSs.

-

A key pair consists of a public key and a private key. Key Pair Service (KPS) stores the public key and you store the private key. If you have imported a public key into a Linux ECS, you can use the corresponding private key, rather than a password, to log in to the ECS.

A key pair consists of a public key and a private key. Key Pair Service (KPS) stores the public key and you store the private key. If you have bound a public key to a Linux ECS, you can use the corresponding private key, rather than a password, to log in to the ECS. You do not need to worry about password interception, cracking, or leakage.

Scenarios

When purchasing an ECS, you are advised to select the key pair login mode. For Windows ECSs, key pairs are required to decrypt the passwords so that you can use the decrypted password to log in.

    (Recommended) Creating a Key Pair on the Management Console

    Scenarios

    You can create a key pair on the management console. After the key pair is created, the public key is automatically stored in the system, and the private key is stored in your local computer. After a key pair is created for an ECS on the management console, ensure that you store your private key in a secure place. Without a private key, you will not be able to log in to the ECS.

            • The remote login function is implemented using customized ports. Therefore, before attempting to log in remotely, ensure that the port to be used is not blocked by the firewall. For example, if the remote login link is xxx:8002, ensure that port 8002 is not blocked by the firewall.
            • If the client OS uses a local proxy and the firewall port cannot be configured on the local proxy, disable the proxy mode and then try logging in remotely.
            • Certain G-series ECSs do not support remote login from the console. If you need to remotely log in to the ECSs, install the VNC server on them. For details, see GPU-accelerated ECSs. You are advised to log in to such ECSs using MSTSC.
            • The French keyboard supports the following browsers: Google Chrome 55, Mozilla Firefox 50, and Microsoft Edge.

              If your browser version is too early to support the French keyboard, use both the soft keyboard and physical keyboard for data input.

                  In Vim, to enable syntax highlighting, display line numbers, and set tab to 4 spaces, create a .vimrc script and inject it into the /root/.vimrc directory during ECS creation. After the ECS is created, vim is automatically configured based on your requirements. This improves ECS configuration efficiency, especially in batch ECS creation scenarios.

                  Application Scenarios for Using Passwords
                  
-
                  Passwords are used to log in to ECSs. If you select the password login mode when creating an ECS, you can use the username and password to log in to your ECS. The password is very important. Keep it secure.
                  
-
                  You can reset the password when:
                  
-
                  • You forgot the password.
                  • The password has expired.
                  • You selected Set password later during the ECS creation.
                  
-
                  Table 1 provides guidance on how to reset your password in different scenarios.

                  What Is a Password?
                  Passwords are used to log in to ECSs. If you select the password login mode when creating an ECS, you can use the username and password to log in to the ECS. The password is very important. Keep it secure.
                  
+
                  You can set a password when creating an ECS. If you do not set a password during the creation or if the password is lost or expired, you can reset the password.
                  
+
                  You can reset the password in any of the following scenarios:
                  • The password is lost.
                  • The password has expired.
                  • You intend to change the initial password at the first login.
                  • You selected Set password later or Key pair for Login Mode during ECS creation.

                  Scenarios
                  ECS metadata includes basic information of an ECS on the cloud platform, such as the ECS ID, hostname, and network information. ECS metadata can be obtained using either OpenStack or EC2 compatible APIs, as shown in Table 1. The following describes the URI and methods of using the supported ECS metadata.

                  Obtaining ECS Details Using Metadata
                  
+
                  Scenarios
                  ECS metadata is a special API that can be locally accessed in the ECS OS. It contains basic ECS details, such as the cloud server ID, hostname, and network details. With ECS metadata, you can exchange basic information in an ECS and configure and manage the ECS OS and applications more conveniently and securely. Metadata allows you to configure information in the OS during initialization and obtain ECS information during service running.
                  
+
                  ECS metadata supports OpenStack and EC2 compatible types, as shown in Table 1.

                  Notes
                  If the metadata contains sensitive data, take appropriate measures to protect the sensitive data, for example, controlling access permissions and encrypting the data.

                  4. 
 
                  Impact on AS
                  • When creating an AS configuration, you can use the User Data function to specify ECS configurations for initialization. If the AS configuration has taken effect in an AS group, the ECSs newly created in the AS group will automatically initialize their configurations based on the specified ECS configurations.
                  • For an existing AS configuration, if its private image does not have Cloud-Init or Cloudbase-Init installed, the login mode of the ECSs created in the AS group where the AS configuration takes effect may fail to take effect.
                    To resolve this issue, see "How Does Cloud-Init Affect the AS Service?" in Auto Scaling User Guide.

                  • Only a running ECS can be logged in to.
                  • Login usernames, passwords, and constraints vary depending on OSs running on the ECSs created using a public image. For details, see Image Management Service - Public Image Introduction.
                  • If an ECS uses key pair authentication, use the password obtaining function available on the management console to decrypt the private key used during ECS creation to obtain a password.
                  • Certain G-series ECSs do not support remote login from the console. If you need to remotely log in to the ECSs, install the VNC server on them. For details, see GPU-accelerated ECSs. You are advised to log in to such ECSs using MSTSC.
                  • If you log in to a GPU-accelerated ECS using MSTSC, GPU acceleration will fail. This is because MSTSC replaces the WDDM GPU driver with a non-accelerated remote desktop display driver. In such a case, you must log in to the ECS using other methods, such as VNC. If the remote login function available on the management console fails to meet your service requirements, you must install a suitable remote login tool, such as TightVNC, on the ECS.
                    To download TightVNC, log in at https://www.tightvnc.com/download.php.

                12. Ultra-high I/O ECSs can use local disks, and can also have EVS disks attached to provide a larger storage size. Note the following when using the two types of storage media:
                  • Only an EVS disk, not a local disk, can be used as the system disk of an ultra-high I/O ECS.
                  • Both EVS disks and local disks can be used as data disks of an ultra-high I/O ECS.
                  • An ultra-high I/O ECS can have a maximum of 60 attached disks (including VBD, SCSI, and local disks). For details about constraints, see Can I Attach Multiple Disks to an ECS?
                  
 
                13. Modify the fstab file to set automatic disk mounting at ECS start. For details, see Configuring Automatic Mounting at System Start.

                15. When an ultra-high I/O ECS is deleted, the data on local NVMe SSDs will also be automatically deleted, which can take some time. As a result, an ultra-high I/O ECS takes a longer time than other ECSs to be deleted. Back up the data before deleting such an ECS.
                16. The data reliability of local disks depends on the reliability of physical servers and hard disks, which are SPOF-prone. It is a good practice to use data redundancy mechanisms at the application layer to ensure data availability. Use EVS disks to store service data that needs to be stored for a long time.
                17. The device name of a local disk attached to an ultra-high I/O ECS is /dev/nvme0n1 or /dev/nvme0n2.
                18. The basic resources, including vCPUs, memory, and image of an ultra-high I/O ECS will continue to be billed after the ECS is stopped. To stop the ECS from being billed, delete it and its associated resources.

                  G7v ECSs use NVIDIA A40 GPUs and support DirectX, Shader Model, OpenGL, and Vulkan. Each GPU provides 48 GiB of GPU memory. Theoretically, the peak FP32 is 37.4 TFLOPS and the peak TF32 tensor is 74.8 TFLOPS | 149.6 TFLOPS (sparsity enabled). They deliver two times the rendering performance and 1.4 times the graphics processing performance of RTX6000 GPUs to meet professional graphics processing requirements.

                  Scenarios
                  After you enable Cloud Trace Service (CTS) and the management tracker is created, CTS starts recording operations on cloud resources. CTS stores operation records (traces) generated in the last seven days.
                  
+
                  Scenarios
                  Cloud Trace Service (CTS) records operations performed on cloud service resources. A record contains information such as the user who performed the operation, IP address, operation content, and returned response message. These records facilitate security auditing, issue tracking, and resource locating. They also help you plan and use resources, and identify high-risk or non-compliant operations.

                    What Is a Trace?
                    A trace is an operation log for a cloud service resource, tracked and stored by CTS. Traces record operations such as adding, modifying, or deleting cloud service resources. You can view them to identify who performed operations and when for detailed tracking.

                        When you create instances, such as cloud servers, containers, and databases, in a VPC subnet, you can use the default security group or create a security group. You can add inbound and outbound rules to the default or your created security group to control traffic from and to the instances in the security group. Here are some common security group configuration examples:
 
                        
 
                        Precautions
                        Note the following before configuring security group rules:
                        
 
                        • Instances associated with different security groups are isolated from each other by default.
                        • Generally, a security group denies all external requests by default, while allowing instances in it to communicate with each other.
                          If required, you can add inbound rules to allow specific traffic to access the instances in the security group.

                          • The default security group is automatically created to simplify the process of creating an instance for the first time. The default security group denies all external requests. To log in to an instance, add a security group rule by referring to Remotely Logging In to an ECS from a Local Server.

                          Security Group
                          A security group is a collection of access control rules for ECSs that have the same security protection requirements and that are mutually trusted. After a security group is created, you can create various access rules for the security group, these rules will apply to all ECSs added to this security group.
                          
 
                          You can also customize a security group or use the default one. The system provides a default security group for you, which permits all outbound traffic and denies inbound traffic. ECSs in a security group are accessible to each other. For details about the default security group, see Default Security Groups and Rules.

                          If two ECSs are in the same security group but in different VPCs, the security group does not take effect. You can use a VPC peering connection to connect the two VPCs first.

                          Security Group Rules
                          After a security group is created, you can add rules to the security group. A rule applies either to inbound traffic (ingress) or outbound traffic (egress). After ECSs are added to the security group, they are protected by the rules of that group.

                                Troubleshooting
                                Before the troubleshooting, check whether the processes or drivers leading to the high CPU or bandwidth usage are normal, and handle the issue accordingly.

                                1. If your ECS runs Windows Server 2008 or 2012, ensure that the available memory is 2 GiB or larger.
                                2. Check whether Windows Update is running.
                                3. Check whether the antivirus software is scanning files and programs on the backend.
                                4. Check whether any applications requiring high CPU or bandwidth resources are running on the ECS. If yes, modify ECS specifications or increase bandwidth.
                                5. If the ECS configuration meets the application requirements, deploy applications separately. For example, deploy the database and applications separately.

                                If the high CPU or bandwidth usage is caused by viruses or Trojan horses, manually stop the affected processes. You are advised to troubleshoot the issue as follows:
                                
 
                                1. Use the commercial-edition antivirus software or install Microsoft Safety Scanner to scan for viruses in security mode.
                                2. Install the latest patches for Windows.
                                3. Run MSconfig to disable all drivers that are not delivered with Microsoft and check whether the fault is rectified. For details, see the official Microsoft document How to perform a clean boot in Windows.

                                • The target ECS is running.
                                • The ECS must have an EIP bound.
                                
 
                                • Access to port 3389 is allowed in the inbound direction of the security group which the ECS belongs to.
                                • Data can be exchanged between the login tool and the target ECS. For example, the default port 3389 is not blocked by the firewall.
                                • RDP has been enabled on the target ECS. By default, RDP has been enabled on the ECSs created using a public image. For instructions about how to enable RDP, see Enabling RDP.

                                  rdesktop
                                  
 
                                  If the message "command not found" is displayed, rdesktop is not installed. In such a case, obtain the rdesktop installation package at the official rdesktop website.
                                  
 
                                2. Run the following command to log in to the ECS:
                                  rdesktop -u Username -p Password -g Resolution EIP

                                  For example, run rdesktop -u administrator -p password -g 1024*720 121.xx.xx.xx.

                                For your first login, use VNC to log in and enable RDP for your ECS. Then, use MSTSC to log in.
                                 
                                By default, RDP has been enabled on the ECSs created using a public image.
