具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
目前的安装过程中存在以下不足：在系统安装过程中的网络规划方法，是通过DHCP(Dynamic Host Configuration Protocol，动态主机配置协议)的方式来为虚拟机分配IP地址(Internet Protocol Address，互联网协议地址)的。通过这种方式获取到的IP地址是随机性的，导致机柜上的主机节点得到的IP地址不是按照在机柜的顺序连续出现的，这会给后期运维造成困难。有鉴于 此，本申请提出了一种数据中心中主机发现与添加方法，能够节约数据中心的部署时间，且有利于后期运维。
参见图1所示，本申请实施例公开了一种数据中心中主机发现与添加方法，应用于数据中心的管理节点，该方法包括：
步骤S11：扫描待添加计算节点，其中，所述管理节点和所述待添加计算节点上的虚拟化系统或超融合系统为出厂时安装完成的。
在实际实施过程中，所述管理节点需要扫描待添加计算节点，以便发现有哪些可以添加的待添加计算节点，其中，所述管理节点和所述待添加计算节点上的虚拟化系统或超融合系统为设备出厂时便安装完成的，所以不需要在到达用户现场，得到用户网络规划之后才开始进行管理节点和计算节点的虚拟化或超融合系统，所以可以大大节约节点上系统部署的时间，也即，可以节约数据中心的部署时间。
为了所述管理节点在扫描时，可以发现所述待添加计算节点，可以在所述管理节点和所述待添加计算节点上安装主机发现服务。所述待添加计算节点上的主机发现服务处于开启状态，这样当打开所述管理节点上的主机发现服务扫描数据中心中的待添加计算节点时，所述管理节点便可以扫描到所述待添加计算节点。
步骤S12：利用IPv6组播方式向扫描到的所述待添加计算节点发送发现报文，并接收所述待添加计算节点在对所述发现报文校验通过后利用IPv6单播方式发送的发现响应报文。
所述管理节点在扫描到所述待添加计算节点之后，还需要利用IPv6组播方式向扫描到的所述待添加计算节点发送发现报文，并接收所述待添加计算节点在对所述发现报文校验通过后利用IPv6单播方式发送的发现响应报文。由于所述待添加计算节点可能未配置IP地址，其中，所述IP地址为IPv4地址，所以所述管理节点利用IPv6组播方式向所述待添加计算节点发送发现报文，而待添加计算节点利用IPv6单播方式向所述管理节点发送发现响应报文。
所述管理节点在与所述待添加计算节点进行通信的过程中，会使用报文进行通信，其中，报文的格式如下：
Figure PCTCN2022074595-appb-000001
Figure PCTCN2022074595-appb-000002
其中，system字段表示发送报文的节点的虚拟化系统或超融合系统的系统类型，Type表示报文的类型，role表示发送报文的节点的角色，也即，发送报文的节点是管理节点还是计算节点，version表示节点的系统版本，management_ipv4表示发送报文的节点的IP地址，其中，所述IP地址为IPv4地址，netmask表示发送报文的节点的掩码，gateway表示发送报文的节点的网关，management_VLAN表示发送报文的节点的VLAN(Virtual Local Area Network，虚拟局域网)，bmc_ip表示发送报文的节点的BMC(Baseboard Management Controller，基板管理控制器)IP，ex_info表示可扩展的字段。
也即，所述管理节点先利用IPv6组播方式向扫描到的所述待添加计算节点发送发现报文，其中，所述发现报文的格式如上，只是Type字段携带报文类型，即DISCOVERY；role携带发出此报文的角色，即管理节点con；verison携带发出此报文的节点所装系统的版本号；management_ipv4、netmask、gateway、management_VLAN表示发出此报文节点的IPv4地址，掩码、网关、VLAN；bmc_ip是指该节点的带外管理IP，在本报文中为空。ex_info为预留字体，用来预留下将来需要携带的字段，方便此功能的拓展。
所述待添加计算节点在接收到所述发现报文之后，还需要对所述发现报文进行校验，并在对所述发现报文校验通过后，向所述管理节点发送发现响应报文。具体的，所述待添加计算节点在所述发现报文校验通过后会利用IPv6单播方式发送的发现响应报文。其中，发现响应报文包括：System字段携带发出此报文的待添加计算节点系统名称；Type字段携带报文类型，即 ACK_DISCOVERY；role携带发出此报文的角色，即计算节点com；verison携带发出此报文的节点所装系统的版本号；management_ipv4、netmask、gateway、management_VLAN表示发出此报文节点的IPv4地址、掩码、网关、VLAN，因为这几个参数有可能还未配置，所以字段可能为空；bmc_ip是指该计算节点的带外管理IP，ex_info为预留字体，用来预留下将来需要携带的字段，方便此功能的拓展。
也即，待添加计算节点发现开始前，需要用户设置一个网段，用于为没有配置IP地址的待添加计算节点配置IP地址。网段大小可以视待添加计算节点多少而定。参见图2所示，为主机发现流程图。当用户通过管理节点扫描待添加计算节点时。管理节点就开始发送DISCOVERY报文，这个报文是以IPv6组播报文的形式在本网络内发送的。而待添加计算节点上默认是配置有IPv6的本地地址，在网络内所有的待添加计算节点都可以收到这个DISCOVERY报文。
当待添加计算节点收到DISCOVERY报文之后，就开始解析DISCOVERY报文内的信息。这些信息包括管理节点的系统类型、角色、系统版本等。其中有些字段，如management_ipv4，management_VLAN在DISCOVERY报文中是空的，因为在这个阶段，待添加计算节点不需要这些信息。待添加计算节点对管理节点的系统类型、角色、系统版本进行校验，校验的内容包括系统是不是和本待添加计算节点一致，是否是由管理节点发出的、管理节点的版本是否和本计算节点一致。如果校验不通过，则不进行任何动作。如果检验能通过。则开始封装ACK_DISCOVERY报文进行报文回应，并在收到的DISCOVERY报文中取出源地址作为ACK_DISCOVERY报文的目的地址，最后将此报文发送出去。报文中封装的信息主要有待添加计算节点的系统类型、角色、系统版本VLAN，如果所述待添加计算节点已配置IP地址，则ACK_DISCOVERY报文还包括当前使用的IPv4地址及VLAN，ACK_DISCOVERY报文不再以组播形式发送而是以单播的IPv6 UDP(User DatagramProtocol，用户数据报协议)报文形式发送，因为此时待添加计算节点已经知道了管理节点的IPv6的地址。管理节点接收到ACK_DISCOVERY报文之后，将报文中的信息解析出来，内容主要有：待添加计算节点的系统类型、角色、系统版本，还可能包括待添加计算节点的IPv4地址、VLAN。
步骤S13：在所述发现响应报文校验通过，且所述待添加计算节点未配置IP地址时，对各个所述发现响应报文中的BMC IP进行排序，并根据所述BMC IP的顺序为对应的所述待添加计算节点分配IP地址，以便相邻所述BMC IP对应的所述待添加计算节点分配到的所述IP地址是连续的，其中，所述IP地址为IPv4地址。
在所述发现响应报文校验通过时，如果所述待添加计算节点未配置IP地址时，所述管理节点对各个所述发现响应报文中的BMC IP进行排序，并根据所述BMC IP的顺序为对应的所述待添加计算节点分配IP地址，以便相邻所述BMC IP对应的所述待添加计算节点分配到的所述IP地址是连续的，其中，所述IP地址为IPv4地址。
也即，在接收所述待添加计算节点在对所述发现报文校验通过后利用IPv6单播方式发送的发现响应报文之后，还包括：对所述发现响应报文进行解析，以从所述发现响应报文中提取出所述待添加计算节点的系统信息和角色信息，其中，所述系统信息包括系统类型及系统版本；根据所述角色信息判断所述发现响应报文是否为计算节点发送的报文；如果是，则判断所述待添加计算节点的系统类型与所述管理节点的系统类型是否一致；如果是，则判断所述待添加计算节点的系统版本与所述管理节点的系统版本是否一致；如果是，则判定所述发现响应报文校验通过。
在所述发现响应报文校验通过时，还需要判断所述发现响应报文中的IPv4字段和VLAN字段是否为空；如果是，则判定所述发现响应报文对应的待添加计算节点未配置IP地址，否则，判定所述待添加计算节点已配置IP地址。
其中，根据所述BMC IP的顺序为对应的所述待添加计算节点分配IP地址，以便相邻所述BMC IP对应的所述待添加计算节点分配到的所述IP地址是连续的，包括：根据所述BMC IP的顺序为对应的所述待添加计算节点分配IP地址，以便相邻所述BMC IP对应的所述待添加计算节点分配到的所述IP地址是连续的；将所述IP地址、所述IP地址对应的掩码、网关以及VLAN封装成配置报文，并通过IPv6单播方式将所述配置报文发送给对应的所述待添加计算节点；接收所述待添加计算节点发送的配置响应报文，以确定所述待添加计算节点的IP地址配置完成，其中，所述配置响应报文为所述待添加 计算节点在利用所述IP地址、所述IP地址对应的掩码、网关以及VLAN进行网络配置后发送的。
其中，配置报文(OFFER_IP报文)中：System字段携带发出此报文的管理节点系统名称；Type字段携带报文类型，即OFFER_IP；role携带发出此报文的角色，即管理节点con；verison携带发出此报文的节点所装系统的版本号；management_ipv4、netmask、gateway、management_vlan这里不再表示发出此报文节点的IPv4地址，掩码、网关、vlan，而是表示管理节点需要给计算节点配置的IPv4地址，掩码、网关、VLAN；bmc_ip是指该节点的带外管理IP，在本报文中为空，ex_info为预留字体，用来预留下将来需要携带的字段，方便此功能的拓展。在配置响应报文(ACK_OFFER_IP报文)中：System字段携带发出此报文的计算节点系统名称；Type字段携带报文类型，即ACK_OFFER_IP；role携带发出此报文的角色，即计算节点com；verison携带发出此报文的节点所装系统的版本号；management_ipv4、netmask、gateway、management_vlan表示发出此报文节点的IPv4地址，掩码、网关、vlan；bmc_ip是指该计算节点的带外管理IP，ex_info为预留字体，用来预留下将来需要携带的字段，方便此功能的拓展。
也即，参见图3所示，为计算节点配置流程图。管理节点在主机发现过程中，管理节点可以在待添加计算节点反馈的ACK_DISCOVERY报文中，获取到计算节点的相关信息。管理节点对这些信息进行校验，包括待添加计算节点的系统类型、角色、系统版本，校验通过后，判断待添加计算节点是否有配置IP地址，若未配置IP地址，则开始封装配置报文(也即，OFFER_IP报文)，报文内容包括了管理节点的系统类型、系统版本、需要给计算节点配置的IPv4地址、掩码、网关、vlan。给待添加计算节点分配的IP地址顺序是以待添加计算节点的带外IP(bmc_ip)的顺序进行分配，因为一般情况下，待添加计算节点的带外IP在与计算机柜上位置是关联、连续的。从而这样可以保证计算节点的连续性。OFFER_IP报文以IPv6单播UDP报文形式发送，因为在上述待添加计算节点发现的过程中，管理节点已经知道了每个待添加计算节点的IPv6单播地址。
当待添加计算节点收到此报文之后，通过报文的类型可以知道，这是一个配置待添加计算节点的OFFER_IP报文，于是需要从报文中取出IPv4地址， vlan，然后开始进行配置。等配置完成后，就开始组装配置响应报文(也即ACK_OFFER_IP报文)，这个报文用来通信管理节点本待添加计算节点配置已经完成。ACK_OFFER_IP报文中，同样携带有待添加计算节点的系统类型、系统版本、计算节点的IPv4地址、掩码、网关、vlan等信息，与ACK_DISCOVERY报文类似，不同的地方就是这里的IPv4地址、vlan是非空的。此时的待添加计算节点IP信息已经配置好了。
步骤S14：在所述待添加计算节点的IP地址配置完成后，向所述待添加计算节点发送添加报文，并接收所述待添加计算节点在对所述添加报文校验通过时返回的添加响应报文，将所述待添加计算节点添加到所述管理节点管理的数据中心中。
在所述待添加计算节点的IP地址配置完成后，也即，所述管理节点接收到所述配置响应报文之后，表示所述待添加计算节点的IP地址配置完成，所述管理节点便可以向所述添加计算节点发送添加报文，以及接收所述待添加计算节点在对所述添加报文校验通过时返回的添加响应报文，将所述待添加计算节点添加到所述管理节点管理的数据中心中。
其中，所述添加报文(也即JOIN报文)中System字段携带发出此报文的管理节点的系统名称；Type字段携带报文类型，即JOIN；role携带发出此报文的角色，即管理节点con；verison携带发出此报文的管理节点所装系统的版本号；management_ipv4、netmask、gateway、management_vlan这里表示管理节点的IPv4地址，掩码、网关、vlan；bmc_ip是指该管理节点的带外管理IP，在本添加报文中为空，ex_info为预留字体，用来预留下将来需要携带的字段，方便此功能的拓展。
其中，添加响应报文(也即，ACK_JOIN报文)中System字段携带发出此报文的待添加计算节点的系统名称；Type字段携带报文类型，即ACK_JOIN；role携带发出此报文的角色，即计算节点com；verison携带发出此报文的待添加计算节点所装系统的版本号；management_ipv4、netmask、gateway、management_vlan表示发出此报文待添加计算节点的IPv4地址，掩码、网关、vlan；bmc_ip是指该待添加计算节点的带外管理IP，ex_info为预留字体，用来预留下将来需要携带的字段，方便此功能的拓展。
也即，参见图4所示，为主机添加流程图。管理节点进行完前述的发现和待添加计算节点配置两个过程后，已经确认了待添加计算节点检验信息正确，配置信息已经完整。这时就管理节点发出JOIN报文，邀请待添加计算节点加入到数据中心，待添加计算节点收到邀请后，就会开始校验，校验信息包括管理节点的系统类型、角色、系统版本等，再次校验是因为，随时有其他的管理节点会向待添加计算节点发出校验，待添加计算节点需要通过校验信息来确认加入的数据中心与自身版本相匹配；加入数据中心后，待添加计算节点不再回应任何其他管理节点(如果有)的DISCOVERY、OFFER_IP、JOIN报文，待添加计算节点的自动发现服务也会停止运行。管理节点收到待添加计算节点的ACK_JOIN报文后，开始纳管待添加计算节点，控制待添加计算节点提供的资源。
在实际的实时过程中，会存在所述管理节点和所述待添加计算节点不属于同一网络的情况，也即，所述管理节点和所述待添加计算节点之间系统通过路由器进行通信，则所述利用IPv6组播方式向扫描到的所述待添加计算节点发送发现报文的过程中，还包括：如果所述待添加计算节点和所述管理节点不属于同一网络，则利用所述待添加计算节点和所述管理节点之间的路由器的组播中继将所述发现报文发送到所述待添加计算节点。
也即，在所述管理节点和所述待添加计算节点不属于同一网络时，需要打开所述管理节点和所述待添加计算节点之间的路由器的组播中继功能，以便通过所述路由器将所述管理节点通过IPv6组播的报文转发到对应的待添加计算节点。
参见图5所示，为数据中心中的主机发现与添加方法应用环境示意图。其中，图中包括管理节点和计算节点，直接通过交换机与管理节点进行通信的计算节点与管理节点处于同一网络，通过路由器(也即图5中的圆形图形表示路由器)才能与管理节点通信的计算节点与管理节点不属于同一网络，所以需要开启该路由器的组播中继功能，在所述路由器开启组播中继功能之后，便可以进行正常进行前述的各个步骤了。
可见，本申请应用于数据中心的管理节点，扫描待添加计算节点，其中，所述管理节点和所述待添加计算节点上的虚拟化系统或超融合系统为出厂时安装完成的。然后利用IPv6组播方式向扫描到的所述待添加计算节点发送发现 报文，并接收所述待添加计算节点在对所述发现报文校验通过后利用IPv6单播方式发送的发现响应报文。在所述发现响应报文校验通过，且所述待添加计算节点未配置IP地址时，对各个所述发现响应报文中的BMC IP进行排序，并根据所述BMC IP的顺序为对应的所述待添加计算节点分配IP地址，以便相邻所述BMC IP对应的所述待添加计算节点分配到的所述IP地址是连续的，其中，所述IP地址为IPv4地址。接着在所述待添加计算节点的IP地址配置完成后，向所述待添加计算节点发送添加报文，并接收所述待添加计算节点在对所述添加报文校验通过时返回的添加响应报文，将所述待添加计算节点添加到所述管理节点管理的数据中心中。由此可见，本申请中的管理节点和计算节点上的虚拟化系统或超融合系统为出厂时便安装完成的，所以不需要在到达用户现场，得到用户网络规划之后才开始进行管理节点和计算节点的虚拟化或超融合系统部署，所以可以大大节约节点上系统部署的时间，也即，可以节约数据中心的部署时间，管理节点在为待添加计算节点分配IP地址时，先将各个计算节点的BMC IP排序，然后根据BMC IP的顺序为对应的所述待添加计算节点分配IP地址，以便相邻所述BMC IP对应的所述待添加计算节点分配到的所述IP地址是连续的，由于BMC IP表明了计算节点在机柜的顺序，所以可以使得各个相连计算节点分配到的IP地址也是连续的，所以有利于后期运维。
参见图6所示，为管理节点与待添加计算节点的交互图。在数据中心中的主机发现与添加过程中，管理节点上的主机发现服务与待添加计算节点上的主机发现服务之间需要进行三个阶段的交互通信，包括发现、配置及添加三个阶段。在发现阶段，管理节点利用IPv6组播方式向扫描到的所述待添加计算节点发送发现报文(DISCOVERY报文)，并接收所述待添加计算节点在对所述发现报文校验通过后利用IPv6单播方式发送的发现响应报文(ACK_DISCOVERY报文)。在配置阶段，在所述发现响应报文校验通过，且所述待添加计算节点未配置IP地址时，管理节点对各个所述发现响应报文中的BMC IP进行排序，并根据所述BMC IP的顺序为对应的所述待添加计算节点分配IP地址，以便相邻所述BMC IP对应的所述待添加计算节点分配到的所述IP地址是连续的，其中，所述IP地址为IPv4地址，将分配到的IP地址通过配置报文(OFFER_IP报文)发送给对应的待添加计算节点，接收待添加计算节点在IP 地址配置完成后发送的配置响应报文(ACK_OFFER_IP报文)。在添加阶段，管理节点向所述待添加计算节点发送添加报文(JOIN报文)，并接收所述待添加计算节点在对所述添加报文校验通过时返回的添加响应报文(ACK_JOIN报文)，将所述待添加计算节点添加到所述管理节点管理的数据中心中。
参见图7所示，本申请实施例公开了一种具体的数据中心中主机发现与添加方法，应用于数据中心的待添加计算节点，该方法包括：
步骤S21：接收管理节点在扫描到所述待添加计算节点后利用IPv6组播方式发送的发现报文，其中，所述管理节点和所述待添加计算节点上的虚拟化系统或超融合系统为出厂时安装完成的。
管理节点会利用IPv6组播方式向所述扫描到的所述待添加计算节点发送发现报文，相应地，所述待添加计算节点便需要接收所述发现报文，其中，所述管理节点和所述待添加计算节点上的虚拟化系统或超融合系统为出厂时安装完成的，以便节约到达客户现场之后根据客户网络规划再进行虚拟化系统或超融合系统安装所需要消耗的时间。
步骤S22：对所述发现报文进行校验，并在所述发现报文校验通过时，利用IPv6单播方式发送所述发现报文对应的发现响应报文，以便所述管理节点在所述发现响应报文校验通过，且所述待添加计算节点未配置IP地址时，对各个所述发现响应报文中的BMC IP进行排序，并根据所述BMC IP的顺序为对应的所述待添加计算节点分配IP地址，以便相邻所述BMC IP对应的所述待添加计算节点分配到的所述IP地址是连续的，其中，所述IP地址为IPv4地址。
所述待添加计算节点在对所述发现报文进行校验，并在所述发现报文校验通过时，利用IPv6单播方式发送所述发现报文对应的发现响应报文，所述管理节点在接收到所述发现响应报文之后，对所述发现响应报文进行校验，并在所述发现响应报文校验通过，且所述待添加计算节点未配置IP地址时，对各个所述发现响应报文中的BMC IP进行排序，并根据所述BMC IP的顺序为对应的所述待添加计算节点分配IP地址，以便相邻所述BMC IP对应的所述待添加计算节点分配到的所述IP地址是连续的，其中，所述IP地址为IPv4地址。
步骤S23：利用所述IP地址对本地网络进行配置。
相应地，所述待添加计算节点便需要利用所述IP地址对本地网络进行配置， 以便可以由所述管理节点管理以及正常对外提供服务。
步骤S24：接收所述管理节点发送的添加报文，并在所述添加报文校验通过后，向所述管理节点发送添加响应报文，以便所述管理节点在接收到所述添加响应报文后，将所述待添加计算节点添加到所述管理节点管理的数据中心中。
在管理节点确定所述待添加计算节点的IP地址配置完成时，便会向所述待添加计算节点发送添加报文，相应地，所述待添加计算节点便需要接收所述添加报文，并对所述添加报文进行校验，在所述添加报文校验通过后，向所述管理节点发送添加响应报文，以便所述管理节点在接收到所述添加响应报文后，将所述待添加计算节点添加到所述管理节点管理的数据中心中。
由于通信报文有可能会在中途丢失，造成所述待添加计算节点在不同的阶段，收到不匹配的报文时，处理过程发生紊乱，所以在所述待添加计算节点上运行状态机，来保证上述过程能够顺利进行。所以待添加计算节点在接收到报文时，获取本地的状态机的当前状态，其中，所述报文包括所述发现报文、配置报文以及所述添加报文；根据所述状态机的当前状态及预设的状态机状态与响应报文类型之间的对应关系判断是否对接收到的报文进行响应，其中，所述状态机状态包括开始状态、发现状态、配置状态、添加状态及完成状态。其中，预设的状态机状态与响应报文类型之间的对应关系为：待添加计算节点初始状态为开始状态start，此时只处理DISCOVERY报文。待添加计算节点接收到DISCOVERY报文后，状态迁移为发现状态(DISCOVERY状态)，此时只处理OFFER_IP报文或者JOIN报文；待添加计算节点接收到OFFER_IP报文后，状态迁移为配置状态(OFFER_IP状态)，此时只处理JOIN报文；添加状态(JOIN状态)可能由OFFER_IP状态或者DISCOVERY状态迁移而来，分别对应修改计算节点配置信息和不修改配置信息两种情况；JOIN状态需要处理任何状态的消息，也就是即便计算节点在JOIN状态时，需要回应任何类型的报文，但JOIN状态不变，仅刷新定时器；当感知到待添加结算节点已经加入管理中心所管理的数据中心之后，待添加计算节点状态迁移为完成状态finish，不再处理任何报文；DISCOVERY状态、OFFER_IP状态、JOIN状态都有相应定时器，在指定时间内没有进行状态迁移，就会重新回到start初始状态。
