Description

一种服务器启动方法与装置
本申请要求于2019年11月29日提交中国专利局、申请号为201911206519.4、发明名称为“一种服务器启动方法与装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及交换机领域，更具体地，特别是指一种服务器启动方法与装置。
背景技术
近年来，随着大数据及云计算等业务的发展，服务器逐渐普及到各行各业。BIOS(基本输入输出系统)与BMC(基板管理控制器)都是服务器上最重要的底层软件之一。BMC的软件使用嵌入式Linux系统，硬件为ARM控制器，BMC负责监控管理服务器系统，BIOS负责初始化服务器硬件，引导服务器进入到OS(操作系统)环境中供客户使用。
服务器上电后，BIOS与BMC同时启动，由于BIOS需要将检测到的服务器信息发送给BMC，所以BIOS开始执行时，会发送self test(自检测试)命令给BMC判断BMC是否已经自检启动完成，此时BIOS会添加一个延时等待时间，一般是5分钟。然而由于BMC挂死时挂死的阶段不一致，导致发送self test的底层函数返回时间不一致，造成等待的延时时间远大于5分钟。这导致由于BMC异常，BIOS等待BMC的响应时间不可控，不是明确的等待5分钟就可以启动，使得启动体验非常差。由于BMC挂死后需要通过BIOS引导OS，进入OS后重新更新BMC的固件程序修复挂死的BMC，因此不明确的引导时间会导致客服修复BMC的处理效率非常低，影响操作作业与客户的感受。
针对现有技术中BMC响应不可控影响服务器启动慢、处理效率低的问题，目前尚无有效的解决方案。
发明内容
有鉴于此，本发明实施例的目的在于提出一种服务器启动方法与装置，能够在可预期的时间内启动操作系统以执行工作或修复BMC，提高工作效率。
基于上述目的，本发明实施例的第一方面提供了一种服务器启动方法，包括由BIOS执行以下步骤：

响应于监听到BMC控制信号指示BMC自检完成，而判定BMC成功启动并立即开始引导服务器的操作系统启动；
响应于监听到跳线控制信号持续指示等待BMC状态判断并且BMC控制信号持续指示BMC自检未完成达到预定时间长度，而判定BMC挂死并立即开始引导服务器的操作系统启动；
响应于操作系统正常启动并且BMC挂死，而使用操作系统刷新BMC的固件以修正BMC的挂死。
在一些实施方式中，跳线控制信号由人工控制；方法还包括：响应于人工判断BMC挂死而使用人工手段将跳线控制信号置为高电平以指示跳过BMC状态判断。
在一些实施方式中，BMC控制信号由BMC输入；方法还包括：响应于BMC自检完成而使用BMC的底层返回函数将BMC控制信号置为高电平以指示BMC自检完成。
在一些实施方式中，跳线控制信号的默认状态为指示等待BMC状态判断的低电平；BMC控制信号的默认状态为指示BMC自检未完成的低电平。
在一些实施方式中，判定BMC挂死并立即开始引导服务器的操作系统启动还包括：中断与BMC的通信连接直到操作系统启动完成。
本发明实施例的第二方面提供了一种服务器启动装置，包括：
处理器；和
存储器，存储有处理器可运行的程序代码，程序代码在被运行时由 BIOS执行以下步骤：

在一些实施方式中，判定BMC挂死并立即开始引导服务器的操作系统启动还包括：中断与BMC的通信连接直到操作系统启动完成。
本发明具有以下有益技术效果：本发明实施例提供的服务器启动方法与装置，通过在接收到服务器的启动信号后，持续监听来自主板的跳线控制信号和BMC控制信号；响应于监听到跳线控制信号指示跳过BMC状态判断，而判定BMC挂死并立即开始引导服务器的操作系统启动；响应于监听到BMC控制信号指示BMC自检完成，而判定BMC成功启动并立即开始引导服务器的操作系统启动；响应于监听到跳线控制信号持续指示等待BMC状态判断并且BMC控制信号持续指示BMC自检未完成达到预定 时间长度，而判定BMC挂死并立即开始引导服务器的操作系统启动；响应于操作系统正常启动并且BMC挂死，而使用操作系统刷新BMC的固件以修正BMC的挂死的技术方案，能够在可预期的时间内启动操作系统以执行工作或修复BMC，提高工作效率。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明提供的服务器启动方法的流程示意图。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白，以下结合具体实施例，并参照附图，对本发明实施例进一步详细说明。
需要说明的是，本发明实施例中所有使用“第一”和“第二”的表述均是为了区分两个相同名称非相同的实体或者非相同的参量，可见“第一”“第二”仅为了表述的方便，不应理解为对本发明实施例的限定，后续实施例对此不再一一说明。
基于上述目的，本发明实施例的第一个方面，提出了一种能够在可预期的时间内启动操作系统的服务器启动方法一个实施例。图1示出的是本发明提供的服务器启动方法的流程示意图。
所述服务器启动方法，如图1所示，包括由BIOS执行以下步骤：
步骤S101：在接收到服务器的启动信号后，持续监听来自主板的跳线控制信号和BMC控制信号；
步骤S103：响应于监听到跳线控制信号指示跳过BMC状态判断，而判定BMC挂死并立即开始引导服务器的操作系统启动；
步骤S105：响应于监听到BMC控制信号指示BMC自检完成，而判 定BMC成功启动并立即开始引导服务器的操作系统启动；
步骤S107：响应于监听到跳线控制信号持续指示等待BMC状态判断并且BMC控制信号持续指示BMC自检未完成达到预定时间长度，而判定BMC挂死并立即开始引导服务器的操作系统启动；
步骤S109：响应于操作系统正常启动并且BMC挂死，而使用操作系统刷新BMC的固件以修正BMC的挂死。
本发明通过使用跳线控制信号和BMC控制信号将BIOS判断BMC状态的逻辑进行了根本上的优化，当BMC异常挂死后，客户可以使用跳线主动跳过判断BMC状态的逻辑；也可以不使用跳线的方式，通过判断BMC状态的电平，完成在等待固定时间后进入OS，完成BMC挂死后的修复措施。此方案解决了现有方案等待时间不确定，等待时间长的问题，对于修正BMC挂死的异常问题处理效率提升非常大。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，可以通过计算机程序来指令相关硬件来完成，所述的程序可存储于一计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。其中，所述的存储介质可为磁碟、光盘、只读存储记忆体(ROM)或随机存储记忆体(RAM)等。所述计算机程序的实施例，可以达到与之对应的前述任意方法实施例相同或者相类似的效果。
在一些实施方式中，跳线控制信号由人工控制；方法还包括：响应于人工判断BMC挂死而使用人工手段将跳线控制信号置为高电平以指示跳过BMC状态判断。
在一些实施方式中，BMC控制信号由BMC输入；方法还包括：响应于BMC自检完成而使用BMC的底层返回函数将BMC控制信号置为高电平以指示BMC自检完成。
在一些实施方式中，跳线控制信号的默认状态为指示等待BMC状态判断的低电平；BMC控制信号的默认状态为指示BMC自检未完成的低电平。
在一些实施方式中，判定BMC挂死并立即开始引导服务器的操作系统启动还包括：中断与BMC的通信连接直到操作系统启动完成。
根据本发明实施例公开的方法还可以被实现为由CPU(中央处理器) 执行的计算机程序，该计算机程序可以存储在计算机可读存储介质中。在该计算机程序被CPU执行时，执行本发明实施例公开的方法中限定的上述功能。上述方法步骤以及系统单元也可以利用控制器以及用于存储使得控制器实现上述步骤或单元功能的计算机程序的计算机可读存储介质实现。
下面根据具体实施例来进一步阐述本发明的具体实施方式。
首先从主板输出两个信号A与B到BIOS。信号A由主板jumper(跳线)输入，信号B由BMC输入，两个信号均默认低电平。
信号 低电平(默认) 高电平
A(跳线控制) 等待BMC状态判断 跳过BMC状态判断
B(BMC控制) BMC状态异常 BMC状态正常
BIOS开机后优先获取信号A的状态。当人工判断BMC已经挂死后，操作jumper将A信号设置为高电平。BIOS若读取A信号为高电平，则跳过BMC状态判断机制，继续往后执行，完成后面的引导OS过程。BIOS若读取A信号为默认低电平，则判断BMC状态，BIOS开始启动后，设置一定时间(例如5分钟)的循环程序，读取判断信号B的电平状态。
B信号默认低电平。当BMC自检成功后，设置信号B为高电平，表明BMC状态正常。在5分钟的循环读取过程中，若信号B为高电平，则跳出循环继续完成后面的引导OS过程，若读取信号B电平一直保持为低电平，则在5分钟循环等待后关掉与BMC的通信机制，继续完成后面的引导OS过程。进入OS后若有需要可以重新刷新BMC固件，修正BMC挂死的故障。
从上述实施例可以看出，本发明实施例提供的服务器启动方法，通过在接收到服务器的启动信号后，持续监听来自主板的跳线控制信号和BMC控制信号；响应于监听到跳线控制信号指示跳过BMC状态判断，而判定BMC挂死并立即开始引导服务器的操作系统启动；响应于监听到BMC控制信号指示BMC自检完成，而判定BMC成功启动并立即开始引导服务器的操作系统启动；响应于监听到跳线控制信号持续指示等待BMC状态判断并且BMC控制信号持续指示BMC自检未完成达到预定时 间长度，而判定BMC挂死并立即开始引导服务器的操作系统启动；响应于操作系统正常启动并且BMC挂死，而使用操作系统刷新BMC的固件以修正BMC的挂死的技术方案，能够在可预期的时间内启动操作系统以执行工作或修复BMC，提高工作效率。
需要特别指出的是，上述服务器启动方法的各个实施例中的各个步骤均可以相互交叉、替换、增加、删减，因此，这些合理的排列组合变换之于服务器启动方法也应当属于本发明的保护范围，并且不应将本发明的保护范围局限在所述实施例之上。
基于上述目的，本发明实施例的第二个方面，提出了一种能够在可预期的时间内启动操作系统的服务器启动装置的一个实施例。服务器启动装置包括：
