Description
本申请要求在2021年9月17日提交中国专利局、申请号为202111090305.2、发明名称为“一种部件独立升级的方法、系统、设备和介质”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。
本申请涉及服务器领域，更具体地，特别是指一种部件独立升级的方法、系统、设备和存储介质。
服务器、存储领域通常机型众多，有两路、四路、八路等不同服务器形态，系统中的可升级固件的部件较多，例如PSU(Power Supply Unit，电源)、网卡、RAID(Redundant Array of Independent Disks，独立硬盘冗余阵列)卡、CPLD(Complex Programmable Logic Device，复杂可编程逻辑器件)等，另外，新型外部设备层出不穷，例如GPU(Graphics Processing Unit，图形处理器)、非易失性内存等，通常BMC(Baseboard Management Controller，基板管理控制器)作为服务器监控管理核心负责可升级部件的固件升级，用户通过远程访问BMC，将待升级部件的固件上传到BMC，BMC通过I2C、JTAG等接口将固件升级到指定部件。
面对BMC要兼容众多款型号部件的升级，业界通用做法有两种：
一是将每个部件的不同升级代码写在BMC中，这种做法的缺点是如果新引入一个型号的部件(例如原本仅支持两个型号的电源，产品量产后又要兼容一款新型号电源)，那么由于BMC中固化的代码中没有该型号的固件升级代码，所以需要BMC重新开发并兼容该型号固件升级代码，并要先将BMC升级到支持新型号部件的版本才能进行新部件的升级；
二是将部件升级代码以lib(库文件)包的形式固化下来，随固件将升级代码上传到BMC中，BMC升级程序引用lib包的升级函数进行固件升级，该方案受限于BMC原有升级程序，必须实现升级程序规定的升级接口函数，开发灵活性和维护便利性较差。
发明内容
有鉴于此，本申请实施例的目的在于提出一种部件独立升级的方法、系统、计算机设备及计算机可读存储介质，本申请通过独立的可执行程序进行镜像文件读取、刷新，不依赖于BMC的其他进程，实现独立升级程序单独上传、执行，避免了BMC代码的改动。

图4为本申请提供的部件独立升级的计算机存储介质的实施例的示意图。
为使本申请的目的、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，对本申请实施例进一步详细说明。
需要说明的是，本申请实施例中所有使用“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，不应理解为对本申请实施例的限定，后续实施例对此不再一一说明。
本申请实施例的第一个方面，提出了一种部件独立升级的方法的实施 例。图1示出的是本申请提供的部件独立升级的方法的实施例的示意图。如图1所示，本申请实施例包括如下步骤：
S1、将指定部件升级程序、配置文件、指定部件待升级镜像和数字签名写入指定部件的升级文件中；
S2、创建检测进程以检测是否接收到升级文件，响应于接收到升级文件，创建升级进程以启动所述升级文件中的指定部件升级程序；
S3、读取所述配置文件并执行所述指定部件升级程序以检测所述指定部件是否满足升级条件；以及
S4、响应于所述指定部件满足升级条件，对所述指定部件待升级镜像进行升级并将所述指定部件待升级镜像刷新到所述指定部件。
将指定部件升级程序、配置文件、指定部件待升级镜像和数字签名写入所述指定部件的升级文件中。
本申请实施例中通过升级文件来对指定部件进行升级，升级文件包括指定部件升级程序、配置文件、指定部件待升级镜像和数字签名四个部分。指定部件升级程序是可执行程序，上传到BMC后将在BMC的嵌入式Linux操作系统下运行，作为一个独立的进程启动升级流程；配置文件用于存储升级程序所需要的参数配置，为了提高升级程序的适用范围，需要将配置信息抽象出来形成配置文件，如物理通道、通道编号、设备地址、待升级镜像适用的设备型号、升级约束条件；指定部件待升级镜像是待升级部件所用的固件镜像文件，升级程序最终将待升级镜像刷新到指定部件；数字签名用于确保升级文件的完整性和安全性，避免非法用户传入恶意的可执行文件。
创建检测进程以检测是否接收到升级文件，响应于接收到升级文件，创建升级进程以启动所述升级文件中的指定部件升级程序。
在一些实施方式中，所述创建升级进程以启动所述升级文件中的指定部件升级程序包括：对所述数字签名进行完整性校验，并判断所述数字签名是否通过所述完整性校验；以及响应于所述数字签名通过所述完整性校 验，创建升级进程。
检测进程用于检测升级文件，引导升级文件中的指定部件升级程序自动执行、以独立APP的形式运行在BMC的OS(操作系统)下(BMC的操作系统是Linux操作系统)。检测进程不断检测是否有升级文件，检测到升级文件后，对升级文件进行数字签名校验，如果校验通过则说明镜像完整，否则镜像不完整。如果升级文件完整，检测进程将按照升级文件格式将指定部件升级程序读取出来，并启动一个进程执行这个指定部件升级程序，这个指定部件升级程序是独立的可执行程序，单独占一个进程，检测进程在这里只是起到了让指定部件升级程序运行起来的目的，该程序运行起来以后就和检测进程是两个完全独立的进程。升级进程独立启动后将具有高度的灵活性，可以对指定部件的访问进行灵活访问，而不依赖于BMC其他正在运行的程序，对比以lib形式，存在升级代码具有高度的开发灵活性，并且独立运行而不影响其他程序运行，增加了运行可靠性。
读取所述配置文件并执行所述指定部件升级程序以检测所述指定部件是否满足升级条件。配置文件用于存储升级程序所需要的参数配置，为了提高指定部件升级程序的适用范围，需要将配置信息抽象出来形成配置文件，如物理通道、通道编号、设备地址、待升级镜像适用的设备型号、升级约束条件；例如升级PSU，要抽象出BMC的Bus通道号、PSU的I2C Slave(从)地址、待升级镜像适用的电源型号、升级约束条件是停止PSU信息访问进程，这样不同的服务器将适用同一套升级程序和不同的配置文件来做到程序的复用。
在一些实施方式中，所述读取所述配置文件并执行所述指定部件升级程序以检测所述指定部件是否满足升级条件包括：从所述配置文件中获取所述指定部件的硬件信息和约束条件，并访问相应的物理通道以获取对应部件的型号；以及将所述型号与所述硬件信息中的型号进行对比以确定所述部件是否为所述指定部件。
在一些实施方式中，所述读取所述配置文件并执行所述指定部件升级程序以检测所述指定部件是否满足升级条件还包括：响应于所述部件为所 述指定部件，获取所述部件的状态信息，判断所述状态信息是否满足所述配置文件中的约束条件；以及响应于所述状态信息满足所述配置文件中的约束条件，确定所述指定部件满足升级条件。
响应于所述指定部件满足升级条件，对所述指定部件待升级镜像进行升级并将所述指定部件待升级镜像刷新到所述指定部件。
在一些实施方式中，所述对所述指定部件待升级镜像进行升级并将所述指定部件待升级镜像刷新到所述指定部件包括：执行所述约束条件以对所述指定部件待升级镜像进行升级，并响应于所述指定部件待升级镜像升级完成，将所述约束条件进行恢复。
在一些实施方式中，所述对所述指定部件待升级镜像进行升级并将所述指定部件待升级镜像刷新到所述指定部件还包括：从所述指定部件待升级镜像中获取升级代码APP程序，并利用所述升级代码APP程序将所述指定部件的固件代码刷写到相应部件的闪存中。
指定部件升级程序是针对指定部件开发的升级代码，如果新加入一款部件，例如PSU，开发人基于电源支持的升级方案开发升级代码，如通过I2C访问PSU进行PSU的Flash升级，该程序要包含：
(1)读取配置文件，明确待升级设备的硬件信息、约束条件，如PSU升级中明确BMC I2C Bus通道号、所要升级电源的I2C Slave地址；如约束条件是停止PSU监控进程需要先停止相应进程，升级结束前再进行约束条件的恢复，即将PSU监控进程重新启动。
(2)目标部件的检测，即访问相应的物理通道检测是否为待升级部件，将配置文件中标记的待升级镜像所支持的型号与当前型号做比对，对比不通过停止升级程序；
(3)可升级状态检测，即检测待升级部件是否具备升级条件，如部件是否健康；
(4)升级指定部件，即读取升级文件中的待升级镜像，按照指定部件的升级说明进行升级。
升级过程记录，升级进度、升级状态记录到指定状态文件。升级结束后升级进程将自动退出。升级程序必须经过适用于BMC嵌入式系统能启动的可执行程序，要通过指定的交叉编译工具来编译得到的可执行程序。
在一些实施方式中，方法还包括：基于所述指定部件升级程序按照预设格式记录升级过程、升级进度和升级结果，并提供解析接口以展示记录的内容。升级状态文件用于记录升级过程、升级进度、升级结果，用于查看升级状态，升级程序按照固定的格式(如Json文件格式)记录文件，BMC提供解析接口给客户展示当前的升级状态。
