The application discloses a cluster operation and maintenance method and device, electronic equipment and a storage medium, relates to the computer technical field, and the method is applied to a management node in a cluster, and comprises the following steps: constructing operation and maintenance components of at least one operating system through at least one first virtual machine; wherein the operation and maintenance components comprise an in-memory operating system image file; the in-memory operating system image file comprises an operation and maintenance execution tool; based on a pre-boot execution environment service program, guiding an execution node in the cluster to load corresponding operation and maintenance components, so that the execution node executes operation and maintenance operations through the operation and maintenance execution tool based on the completed in-memory operating system. Compared with operation and maintenance operations executed through a hard disk operating system, the in-memory operating system has the characteristic that system operations are restored after restarting, damage of viruses and malicious software to the operating system is avoided, operation and maintenance safety of the cluster is improved, and operation and maintenance efficiency of the cluster is improved.

The present disclosure relates to the technical field of computers. Disclosed are a server preboot function self-adaptive supporting method and apparatus. The method includes: when target indication information is acquired, traversing network card devices in a network card device library, where the target indication information is configured for representing that a target object has a customization requirement on enabling / disabling of a preboot execution environment function; selecting, from the network card devices, a target network card device corresponding to the customization requirement, and a target port of the target network card device; enabling the preboot execution environment function of the target port, and disabling the preboot execution environment function of a reference port other than the target port in the target network card; and compiling the customization requirement into a version file and burning the version file into a read-only memory of a basic input / output system.

The application discloses an operating system installation method and device, equipment and a storage medium, which are applied to a basic input / output system, and relate to the technical field of ARM servers, and the method comprises the following steps: a pre-boot execution environment is built in the process of powering on the current ARM server, so that the pre-boot execution environment is used to guide the installation of the operating system of the ARM server; the installation process of the operating system of the ARM server guided by the pre-boot execution environment is monitored, and it is judged whether the installation process is abnormal; when the installation process is abnormal, a target network card in the basic input / output system is determined, and the target network card is used to guide the pre-boot execution environment, so that the operating system of the ARM server is installed. Through the technical scheme, the ARM server can maintain an efficient and stable running state when using virtualization operation, and help the development of the domestic ARM CPU platform server service and the domestic cause.

The application discloses a pre-start execution environment starting method, a computer device and related products, and relates to the technical field of computers. The method comprises the following steps: monitoring a timeout event of a monitoring timer and a network reply message event when a first network driver is triggered to unload a target by a second network driver loading and the first network driver has sent a network release message in the target unloading process; triggering the first network driver to resend the network release message when the timeout event is monitored and the network reply message event is not monitored; and forcibly terminating a target event polling operation and transferring network control from the first network driver to the second network driver when the resending frequency exceeds a preset retransmission threshold, so that the second network driver takes over and continues to execute a starting process based on its own network protocol stack. The technical problem of deadlock in the pre-start execution environment starting process in the related art is solved, and the technical effect of improving the starting reliability of the pre-start execution environment is achieved.

The present embodiments relate to a secure boot partition for a cloud computing device of a cloud computing system. The computing device of the cloud computing system can transmit a first request for a pre-boot execution environment executable from a smart network interface card (SmartNIC). The computing device can receive the pre-boot environment executable from the SmartNIC and verify the pre-boot execution environment executable. The computing device can execute the pre-boot execution environment executable. Executing the pre-boot execution environment executable can include transmitting a second request secure boot metadata from the SmartNIC and receiving the secure boot metadata. Executing the pre-boot execution environment executable can further include mounting a boot partition, loading a boot loader obtained from the boot partition, verifying the boot loader based at least in part on the secure boot metadata, and executing the boot loader in response to verifying the boot loader.
