Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In view of the foregoing, a first aspect of the embodiments of the present invention provides an embodiment of a server startup method. As shown in fig. 1, it includes the following steps:
s10, after detecting that a server is powered on and started up, a substrate management controller runs a watchdog timing program and sets first appointed time based on the watchdog timing program;
s20, in the first appointed time, the baseboard management controller detects whether first safety starting information sent by a basic input and output system is received;
s30, responding to the fact that the baseboard management controller receives the first safety starting information in the first appointed time, closing the watchdog timing program, and sending confirmation information to the basic input and output system;
and S40, after receiving the confirmation information, the basic input and output system calls a boot loader to boot the server operating system to start.
Specifically, after the server is powered on, the BMC detects that the server is powered on and started, runs a watchdog timing program, and sets an appointed time through the watchdog timing program. In a predetermined time, the BIOS (Basic Input Output System) sends predetermined secure boot information to the BMC through an IPMI (Intelligent Platform Management Interface) protocol. If the BMC confirms that the safe starting information sent by the BIOS is received within the appointed time, the watchdog program is closed and fed back to the BIOS confirmation information through the IPMI protocol, and the BIOS calls a boot loader Bootloader to normally start the boot operating system after receiving the BMC confirmation information. When the Bootloader loads a system kernel, operating a corresponding GPIO register according to convention, after detecting the change of the GPIO register, the BMC runs a watchdog timing program, and sets another convention time through the watchdog timing program. And in the appointed time, the built-in service of the operating system sends the safety starting information to the BMC through the IPMI protocol. And after confirming that the safe starting information of the operating system is received, the BMC closes the watchdog timing program.
By the scheme, the server is safely started, and compared with the existing safe starting method, the method is safer, does not occupy hardware resources, and ensures safe and reliable operation of the server.
In some embodiments, invoking the boot loader to boot the server operating system to boot comprises:
calling the bootstrap loader to load an operating system kernel and operating a corresponding GPIO pin to change a level signal output by the GPIO pin;
responding to the fact that the substrate management controller detects that level signals output by GPIO pins corresponding to the boot loader are changed, running the watchdog program, and setting second appointed time based on the watchdog timer program;
in the second appointed time, the baseboard management controller detects whether second safety starting information sent by built-in services of an operating system is received;
and in response to the substrate management controller receiving the second secure start information within the second appointed time, closing the watchdog timer to start the operating system.
In a specific embodiment, the secure boot of the server is implemented by the following scheme.
The secure startup of the server is completed through GPIO (General-purpose input/output) pin detection, a watchdog program, an IPMI protocol and the like. After the machine is powered on, the BMC detects the level signal change of the corresponding GPIO pin and runs a watchdog program. Within a given time, the BIOS needs to send secure boot information to the BMC via IPMI protocol. If the BMC does not feed the dog in time, namely the BMC does not receive the information sent by the BIOS, the BMC directly operates the GPIO or shuts down through the CPLD. If the BIOS sends corresponding information to the BMC through the IPMI protocol within the appointed time, the BMC closes the watchdog program and sends confirmation information to the BIOS through the IPMI protocol, and the BIOS starts normally after receiving the confirmation information of the BMC, finds the Bootloader and guides the operating system. If the BMC does not reply to the BIOS confirmation message, the BIOS cannot further boot the system. When the system is normally started, the Bootloader loads a system kernel, a GPIO signal corresponding to appointed operation is operated, and the BMC runs a watchdog program after detecting that the GPIO signal changes. And in appointed time, the built-in service of the operating system sends the safety starting information to the BMC through the IPMI protocol. And after confirming that the safe start of the operating system is received, the BMC closes the watchdog timing program. Otherwise, the BMC directly operates the GPIO or the CPLD to shut down.
By the scheme, the server is safely started, hardware resources are not occupied, interaction between the basic input and output system and the substrate management controller, interaction between the boot loader and the substrate management controller are increased by utilizing the IPMI protocol, operation that the substrate management controller needs to be unplugged to start the server is prevented, and compared with the existing safe starting method, the method is safer, and safe and reliable operation of the server is guaranteed.
In some embodiments, the method further comprises:
and in response to the fact that the substrate management controller does not receive the second safety starting information within the second appointed time, controlling a corresponding GPIO pin or a complex programmable logic device to enable the server to be shut down.
In some embodiments, the method further comprises:
and in response to the fact that the substrate management controller does not receive the first safety starting information within the first appointed time, controlling a corresponding GPIO pin or a complex programmable logic device to enable the server to be shut down.

and in the first appointed time, the basic input and output system sends first safety starting information to the substrate management controller through an IPMI protocol, and the substrate management controller detects whether the first safety starting information sent by the basic input and output system is received.
In some embodiments, sending acknowledgement information to the basic input output system comprises:
