在一个实施例中，如图3所示，提供了一种文件分发方法，本实施例以该方法应用于如图1所示的电子设备为例进行说明。该方法包括：
操作302，获取文件信息，文件信息中包含文件标识和下载地址，文件标识与下载地 址之间存在映射关系。
其中，文件标识用于唯一标识文件。文件标识可以由数字、字母、文字、符号中至少一种组成。文件标识具体可以是文件名称或者文件MD5值等不限于此。文件MDS值是通过MD5信息摘要算法(Message-Digest Algorithm)计算得到的。下载地址可以是节点标识或者URL(Uniform Resource Locator,统一资源定位符)。节点标识用于唯一地标识服务节点。节点标识具体可以是节点的MAC(Media Access Control，媒体访问控制)地址、节点的IP(Internet Protocol，互联网协议)地址等不限于此。文件标识和下载地址之间的映射关系用于表示某个下载地址所对应的节点包含文件。或者，文件标识和下载地址之间的映射关系用于表示某个文件标识所对应的文件在哪些下载地址所对应的节点内保存。
具体地，本申请应用于文件分发***的文件分发场景中。电子设备获取存储的文件信息，文件信息中包含文件标识和下载地址，文件标识与下载地址之间存在映射关系。文件信息中还可以包含是否分发成功、分发的时间、分发的服务器集群标识中至少一种。
操作304，获取待部署文件标识以及对应的待部署节点标识。
其中，待部署文件标识是指待部署文件所对应的标识。待部署节点标识是指待部署节点所对应的标识。待部署文件标识和待部署节点标识的数量均不限。
具体地，终端获取选取的或输入的待部署文件标识以及对应的待部署节点标识。电子设备从终端获取该待部署文件标识以及对应的待部署节点标识。例如，待部署文件标识为“文件A”对应的待部署节点标识为“节点Z、节点Y和节点X”。待部署文件标识和对应的待部署节点标识用于表示哪些节点需要部署哪些待部署文件。
操作306，根据映射关系确定与待部署文件标识相对应的目标下载地址。
其中，目标下载地址所对应的目标节点包含该待部署文件标识所对应的待部署文件。
具体地，电子设备根据文件标识和节点标识之间的映射关系，确定包含待部署文件标识的目标节点的目标下载地址。例如，映射关系中包含“文件A”对应的节点标识仅有“节点P”，“文件B”对应的节点标识为“节点M和节点N”，待部署文件标识为“文件A”，那么根据映射关系，确定与待部署文件标识“文件A”相对应的目标下载地址仅有“节点P”。
操作308，向待部署节点标识所对应的待部署节点发送携带有待部署文件标识和目标下载地址的第一文件部署指令，第一文件部署指令用于指示待部署节点根据待部署文件标识以及目标下载地址部署对应的待部署文件。
其中，部署也可以称为安装，部署对应的待部署文件可以是指安装待部署文件所对应的程序包。例如程序包可为二进制程序包，比如java的jar包。
具体地，电子设备向待部署节点标识所对应的待部署节点发送携带有待部署文件标识和目标下载地址的第一文件部署指令。即该第一文件部署指令中可包括待部署文件标识和目标下载地址。第一文件部署指令还可以包含其他数据，例如源文件下载地址等。待部署节点接收到该文件部署指令后，从目标下载地址所对应的目标节点中获取并部署待部署节点标识对应的待部署文件。例如，电子设备向待部署节点发送携带有待部署文件标识“文件A”和目标下载地址“节点P”的文件部署指令，则待部署节点从节点P中获取文件A并部署。
本实施例中，若目标下载地址为至少两个，待部署节点从任意一个目标下载地址所对应的目标节点中获取并部署待部署节点标识对应的待部署文件。
本申请实施例中的文件分发方法，获取文件信息，文件信息中包含文件标识与节点标识，文件标识与下载地址之间存在映射关系，获取待部署文件标识以及对应的待部署节点标识，根据映射关系确定与待部署文件标识相对应的目标下载地址，向待部署节点标识所对应的待部署节点发送携带有待部署文件标识和目标下载地址的第一文件部署指令，该第一文件部署指令用于指示待部署节点根据待部署文件标识以及目标下载地址部署对应的 待部署文件，则待部署节点每次不一定只从文件存储服务器中获取待部署文件，减少了文件存储服务器的服务资源占用，并且单一的文件存储服务器由于服务资源例如内存、网络带宽等的限制，可同时服务的对象有限，采用本申请实施例中的方法能够提高***的可扩展性；并且若文件存储服务器出现故障，也能正常部署待部署文件。
在一个实施例中，根据映射关系确定与待部署文件标识相对应的目标下载地址，包括：从映射关系中选取与待部署文件标识对应的候选下载地址；从候选下载地址中确定与待部署节点之间传输距离在预设距离范围内的目标节点所对应的目标下载地址，其中，待部署节点标识与待部署节点相对应。
其中，候选下载地址所对应的候选节点即为包含待部署文件的候选节点所对应的标识。预设距离范围是指在一定距离范围内的，预设距离范围可预先设置。电子设备可预先设置哪些节点之间的传输距离在预设范围内。
具体地，电子设备从映射关系中选取与待部署文件标识对应的候选下载地址，从候选下载地址中确定与待部署节点之间传输距离在预设距离范围内的目标节点所对应的目标下载地址。例如，待部署文件标识对应的候选下载地址包括位于中国的节点、位于日本的节点和位于美国的节点。那么，位于中国的节点和位于日本的节点之间的传输距离可设为在预设范围内。
本实施例中的文件分发方法，从映射关系中选取与待部署文件标识对应的候选下载地址，从候选下载地址中确定与待部署节点之间传输距离在预设距离范围内的目标节点所对应的目标下载地址，待部署节点标识与待部署节点相对应，由于与待部署节点之间的传输距离在预设距离范围内的目标节点，在进行数据传输时的信号较好、传输速度较快，因此，可以提高文件分发的效率，也提高文件部署效率。
在一个实施例中，从候选下载地址中确定与待部署节点之间传输距离在预设距离范围内的目标节点所对应的目标下载地址，包括：从候选下载地址中获取与待部署节点位于同一服务器集群的节点所对应的参考下载地址，将参考下载地址作为目标下载地址。
其中，同一服务器集群即同一机房。且同一服务器集群之间的通信通过局域网进行通信。与待部署节点之间传输距离在预设距离范围内的目标节点包括与待部署节点位于同一服务器集群的节点。且位于同一服务器集群的参考节点可视为与待部署节点之间传输距离最小。
具体地，电子设备从候选下载地址中获取与待部署节点位于同一服务器集群的节点所对应的参考下载地址，将参考下载地址作为目标下载地址。
本实施例中的文件分发方法，从候选下载地址中获取与待部署节点位于同一服务器集群的节点所对应的参考下载地址，作为目标下载地址，能够得到包含待部署文件的且与待部署节点之间距离较近的目标节点所对应的标识，提高文件分发效率，也提高了文件部署效率。
在一个实施例中，将参考下载地址作为目标下载地址，包括：检测每个参考下载地址所对应的待部署文件标识的文件时间戳；将文件时间戳在预设时间范围内的参考下载地址作为目标下载地址。
具体地，文件时间戳可用于表示该待部署文件的创建时间、或者该部署文件的分发时间等。电子设备检测每个参考下载地址所对应的待部署文件标识的文件时间戳，将文件时间戳在预设时间范围内的参考下载地址作为目标下载地址。预设时间范围内可以是指在某个预设时长范围内，例如10天内。预设时间范围内还可以是指该待部署文件标识的文件时间戳，是否在该参考下载地址所对应的最新的预设数量个文件时间戳中。例如，该待部署文件标识的文件时间戳是否在该参考下载地址所对应的最新的5个文件时间戳中。
本实施例中的文件分发方法，检测每个参考下载地址所对应的待部署文件标识的文件时间戳，将文件时间戳在预设时间范围内的参考下载地址作为目标下载地址，由于若待部 署文件标识对应的文件时间戳太久远，对应的该待部署文件可能已经不在参考节点中，即参考节点删除了该待部署文件，因此将文件时间戳在预设时间范围内的参考下载地址作为目标下载地址，能够得到真正包含待部署文件的目标节点，提高待部署节点成功获取待部署文件的概率。
在一个实施例中，该文件分发方法还包括：若未获取到文件时间戳在预设时间范围内的参考下载地址，从候选下载地址中，确定与待部署节点之间传输距离在预设距离范围内、且除与待部署节点位于同一服务器集群外的目标节点所对应的目标下载地址。
具体地，若未获取到文件时间戳在预设时间范围内的参考下载地址，从与待部署节点标识所对应的候选下载地址中，确定与待部署节点之间传输距离在预设距离范围内、且除与待部署节点位于同一服务器集群之外的目标节点所对应的目标下载地址。例如，电子设备从候选下载地址中获取与待部署节点位于同一服务器集群的节点所对应的参考下载地址A，而A节点中的该待部署文件标识对应的文件时间戳未在预设时间范围内，即A节点中的该待部署文件可能过期。那么电子设备可从候选下载地址中，确定与待部署节点位于相邻服务器集群的目标节点所对应的目标下载地址。
本实施例中的文件分发方法，若未获取到文件时间戳在预设时间范围内的参考下载地址，从候选下载地址中，确定与待部署节点之间传输距离在预设距离范围内、且除与待部署节点位于同一服务器集群外的目标节点所对应的目标下载地址，能够提高获取到待部署文件的概率。
在一个实施例中，向待部署节点标识所对应的待部署节点发送携带有待部署文件标识和目标下载地址的第一文件部署指令，包括：
向待部署节点标识所对应的待部署节点发送携带有待部署文件标识、目标下载地址和源文件下载地址的第一待部署指令，第一待部署指令还用于若待部署节点从目标下载地址所对应的目标节点下载待部署文件失败，根据源文件下载地址部署待部署文件。
其中，源文件下载地址可以是指用于存储文件的文件存储服务器的IP地址，或者是URL(Uniform Resource Locator,统一资源定位符)地址等。
具体地，待部署节点从目标节点下载待部署文件失败的情况可以是传输通路受阻、待部署文件损坏等不限于此。电子设备向待部署节点标识所对应的待部署节点发送携带有待部署文件标识、目标下载地址和源文件下载地址的第一待部署指令。第一待部署指令还用于若待部署节点无法从目标下载地址对应的目标节点成功下载待部署文件，从源文件下载地址下载该待部署文件并部署该待部署文件。
本实施例中的文件分发方法，向待部署节点标识所对应的待部署节点发送携带有待部署文件标识、目标下载地址和源文件下载地址的第一待部署指令，第一待部署指令还用于若待部署节点从目标节点下载待部署文件失败，根据源文件下载地址部署待部署文件，即待部署节点优先通过目标节点部署文件，能够提供另一种下载待部署文件的机制，保证待部署节点成功部署待部署文件。
在一个实施例中，该文件分发方法还包括：若无法从文件信息中获取到与待部署节点标识相对应的目标下载地址，向待部署节点标识对应的待部署节点发送携带有源文件下载地址的第二文件部署指令，该第二文件部署指令用于指示待部署节点根据源文件下载地址部署待部署文件。
具体地，若电子设备无法从文件信息中获取到与待部署节点标识相对应的目标下载地址，向待部署节点标识对应的待部署节点发送携带有源文件下载地址的第二文件部署指令。待部署节点可从该源文件下载地址获取待部署文件并部署该待部署文件。即该待部署文件标识对应的待部署文件还未被任意节点部署。
例如，电子设备从终端获取待部署文件标识以及对应的待部署节点标识。那么从文件信息中获取与第一个待部署节点标识相对应的目标下载地址时，由于可能还没有其他节点 部署了该待部署文件，则电子设备无法从文件信息中获取到与待部署节点标识对应的目标下载地址。因此电子设备向待部署节点标识对应的待部署节点发送源文件下载地址，以使待部署节点从源文件下载地址下载待部署文件。
本实施例中的文件分发方法，若无法从文件信息中获取到与待部署节点标识相对应的目标下载地址，向待部署节点发送携带有源文件下载地址的第二文件部署指令，第二文件部署指令用于指示待部署节点根据源文件下载地址部署待部署文件，由于可能还没有其他节点部署了该待部署文件，则电子设备无法从文件信息中获取到与待部署节点标识对应的目标下载地址，因此提供另一种下载待部署文件的机制，保证待部署节点成功部署待部署文件。
在一个实施例中，在向待部署节点标识所对应的待部署节点发送携带有待部署文件标识和目标下载地址的第一文件部署指令之后，该文件分发方法还包括：接收待部署节点返回的与待部署文件所对应的下载结果；响应于下载结果为下载成功，将待部署文件标识所对应的待部署节点标识更新为可用状态，以使待部署节点中的待部署文件能被下载。
其中，下载结果即待部署节点是否能从目标节点中成功获取到待部署文件。即下载结果包括下载成功或下载失败。
具体地，待部署节点从目标节点下载待部署文件，并生成下载结果，向电子设备发送该下载结果。电子设备接收待部署节点返回的与待部署文件所对应的下载结果。响应于下载结果为下载成功，电子设备将待部署文件标识所对应的待部署节点标识，更新为可用状态，以使待部署节点中的该待部署文件能够被下载。例如，待部署文件标识对应的节点标识A为不可用状态。待部署节点返回A文件下载成功，响应于下载结果为下载成功，电子设备将待部署文件标识所对应的节点标识A更新为可用状态，那么其他节点即可从该待部署节点下载该待部署文件。
本实施例中的文件分发方法，接收待部署节点返回的与待部署文件所对应的下载结果，响应于下载结果为下载成功，将待部署文件标识所对应的待部署节点标识更新为可用状态，以使待部署节点中的待部署文件能被下载，增加了下载该待部署文件的途径。
在一个实施例中，如图4所示，为一个实施例中预下载的流程示意图，在获取文件信息之前，该文件分发方法还包括：
步骤402，获取终端发送的预下载节点标识和对应的待部署文件标识，向预下载节点标识对应的预下载节点发送携带有待部署文件标识和源文件下载地址的预下载指令，预下载指令用于指示预下载节点标识对应的预下载节点从源文件下载地址获取待部署文件标识所对应的待部署文件，预下载节点标识是待部署节点标识中的至少一个。
向待部署节点标识所对应的待部署节点发送携带有待部署文件标识和目标下载地址的第一文件部署指令，第一文件部署指令用于指示待部署节点根据待部署文件标识以及目标下载地址部署对应的待部署文件，包括：
步骤404，向预下载节点发送携带有待部署文件标识和目标下载地址的第一文件部署指令，第一文件部署指令用于指示预下载节点部署对应的待部署文件，并且若预下载节点无法部署待部署文件，根据待部署文件标识以及目标下载地址部署对应的待部署文件。
其中，预下载节点标识是待部署节点标识中的至少一个。预下载是指在部署之前提前下载文件。预下载指令则用于在获取文件信息之前使待部署节点下载该待部署文件。
具体地，在进行文件部署之前，可提前下载待部署文件。终端获取预下载节点标识以及对应的待部署文件标识，向电子设备发送预下载节点标识以及对应的待部署文件标识。电子设备接收终端发送的预下载节点和对应的待部署文件标识，向预下载节点标识对应的预下载节点发送携带有待部署文件标识和源文件下载地址的预下载指令。那么在进行文件部署时，电子设备依旧向预下载节点发送携带有待部署文件标识和目标下载地址的第一文件部署指令。
本实施例中的文件分发方法，向预下载节点发送携带有待部署文件标识和源文件下载地址的预下载指令，预下载指令用于指示预下载节点从源文件下载地址获取待部署文件，且若接收到第一文件部署指令，部署待部署文件，若无法部署该待部署文件，根据待部署文件标识以及目标下载地址部署对应的待部署文件，能够快速部署文件。
在一个实施例中，一种文件分发方法，包括：
步骤a1，获取终端发送的预下载节点标识和对应的待部署文件标识，向预下载节点标识所对应的预下载节点发送携带有待部署文件标识和源文件下载地址的预下载指令，预下载指令用于指示预下载节点标识对应的预下载节点从源文件下载地址获取待部署文件标识所对应的待部署文件，预下载节点标识是待部署节点标识中的至少一个。
步骤a2，获取文件信息，文件信息中包含文件标识与下载地址，文件标识与下载地址之间存在映射关系。
步骤a3，获取待部署文件标识以及对应的待部署节点标识。
步骤a4，从映射关系中选取与待部署文件标识对应的候选下载地址。
步骤a5，从候选下载地址中获取与待部署节点位于同一服务器集群的节点所对应的参考下载地址。
步骤a6，检测每个参考下载地址所对应的待部署文件标识的文件时间戳。
步骤a7，将文件时间戳在预设时间范围内的参考下载地址作为目标下载地址，其中，待部署节点标识与待部署节点相对应。
步骤a8，若未获取到文件时间戳在预设时间范围内的参考下载地址，从候选下载地址中，确定与待部署节点之间传输距离在预设距离范围内、且除与待部署节点位于同一服务器集群之外的目标节点所对应的目标下载地址。
步骤a9，向预下载节点发送携带有待部署文件标识和目标下载地址的第一文件部署指令，第一文件部署指令用于指示预下载节点部署对应的待部署文件，并且若预下载节点无法部署待部署文件，根据待部署文件标识以及目标下载地址部署对应的待部署文件。
步骤a10，若无法从文件信息中获取到与待部署节点标识相对应的目标下载地址，向待部署节点标识对应的待部署节点发送携带有源文件下载地址的第二文件部署指令，第二文件部署指令用于指示待部署节点根据源文件下载地址部署待部署文件。
本申请实施例中的文件分发方法，获取文件信息，文件信息中包含文件标识与下载地址之间的映射关系，获取待部署文件标识以及对应的待部署节点标识，根据映射关系确定与待部署文件标识相对应的目标下载地址，向待部署节点标识所对应的待部署节点发送携带有待部署文件标识和目标下载地址的第一文件部署指令，该第一文件部署指令用于指示待部署节点根据待部署文件标识以及目标下载地址部署对应的待部署文件，则待部署节点每次不一定只从文件存储服务器中获取待部署文件，减少了存储文件的服务器的服务资源占用，并且单一的文件存储服务器由于服务资源例如内存、网络带宽等的限制，可同时服务的对象有限，采用本申请实施例中的方法能够提高***的可扩展性；并且若某一存储文件的服务器出现故障，也能正常部署待部署文件。
在一个实施例中，如图5所示，为一个实施例中文件分发方法的架构示意图，包括发布***(即文件分发服务器)、机房A(即服务器集群A)、机房B(即服务器集群B)和机房C(即服务器集群C)。发布***中可记录文件分布元数据(即文件信息)，根据文件信息确定目标下载地址。机房A中包括a节点502和b节点504，机房B中包括c节点508和d节点510，机房C中包括e节点512和f节点514。发布***可向a节点、b节点、c节点、d节点、e节点和f节点中至少一个节点发布部署任务。而a节点、b节点、c节点、d节点、e节点和f节点根据待部署文件标识以及目标下载地址部署对应的待部署文件。图中的箭头仅做示意。
传统的发布架构，每次发布都要从源文件服务器下载文件，源文件服务器很容易受机房位置和宽带等因素影响，下载效率低下。
1、部署应用前，首先发布***将本次发布信息记录下来，然后发布***通过已经记录的元数据，根据同机房优先、其次相邻机房的算法(即传输距离在预设距离范围内)，计算出一个最优(优先同机房，其次相邻机房)的发布文件下载地址(即目标下载地址)。如果存在最优的发布文件下载地址，发布***将源文件下载地址和最优的发布文件下载地址传递给待部署节点。
2、应用部署时，待部署节点优先通过最优的发布文件下载地址下载，如果下载失败，从源文件下载地址下载，从而保证待部署文件的可用性。
3、文件部署结束后，部署节点将下载结果通知给发布***，发布***将本次记录的文件位置修改为可用，这样就实现了待部署节点间的文件共享下载。
4、发布前针对机房(服务器集群)进行预下载(数据预热)，整体提升首次分发效率。
本申请的技术方案，在传统资源的环境下建立起节点间的文件共享体系，突破部署(尤其是海外部署)的下载瓶颈，提升部署效率。同时，通过源文件下载地址，保证了下载的可靠性。更不用单独维护文件分发服务集群，将发布和文件下载加速完美结合在一起。通过记录文件的下载去向、计算和配置，共享节点间的文件，整合发布***，不需要额外的资源申请和占用，一方面提升部署效率，解决因为宽带限制带来的下载瓶颈，同时，即使加速过程失败，通过源文件下载地址进行下载，保证了其可用性，风险可控。
应该理解的是，虽然图3和图4的流程图中的各个操作按照箭头的指示依次显示，但是这些操作并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些操作的执行并没有严格的顺序限制，这些操作可以以其它的顺序执行。而且，图3和图4中的至少一部分操作可以包括多个子操作或者多个阶段，这些子操作或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子操作或者阶段的执行顺序也不必然是依次进行，而是可以与其它操作或者其它操作的子操作或者阶段的至少一部分轮流或者交替地执行。

在一个实施例中，确定模块606用于从映射关系中选取与待部署文件标识对应的候选下载地址；从候选下载地址中确定与待部署节点之间传输距离在预设距离范围内的目标节点所对应的目标下载地址，其中，待部署节点标识与待部署节点相对应。
本实施例中的文件分发装置，从映射关系中选取与待部署文件标识对应的候选下载地址，从候选下载地址中确定与待部署节点之间传输距离在预设距离范围内的目标节点所对应的目标下载地址，待部署节点标识与待部署节点相对应，由于与待部署节点之间的传输距离在预设距离范围内的目标节点，在进行数据传输时的信号较好、传输速度较快，因此，可以提高文件分发的效率，也提高文件部署效率。
在一个实施例中，确定模块606用于从候选下载地址中获取与待部署节点位于同一服务器集群的节点所对应的参考下载地址，将参考下载地址作为目标下载地址。
本实施例中的文件分发装置，从候选下载地址中获取与待部署节点位于同一服务器集群的节点所对应的参考下载地址，作为目标下载地址，能够得到包含待部署文件的且与待部署节点之间距离较近的目标节点所对应的标识，提高文件分发效率，也提高了文件部署效率。
在一个实施例中，确定模块606用于检测每个参考下载地址所对应的待部署文件标识的文件时间戳；将文件时间戳在预设时间范围内的参考下载地址作为目标下载地址。
本实施例中的文件分发装置，检测每个参考下载地址所对应的待部署文件标识的文件时间戳，将文件时间戳在预设时间范围内的参考下载地址作为目标下载地址，由于若待部署文件标识对应的文件时间戳太久远，对应的该待部署文件可能已经不在参考节点中，即参考节点删除了该待部署文件，因此将文件时间戳在预设时间范围内的参考下载地址作为目标下载地址，能够得到真正包含待部署文件的目标节点，提高待部署节点成功获取待部署文件的概率。
在一个实施例中，确定模块606还用于若未获取到文件时间戳在预设时间范围内的参考下载地址，从候选下载地址中，确定与待部署节点之间传输距离在预设距离范围内、且除与待部署节点位于同一服务器集群外的目标节点所对应的目标下载地址。

在一个实施例中，文件分发装置还包括更新模块，更新模块用于接收待部署节点返回的与待部署文件所对应的下载结果；响应于下载结果为下载成功，将待部署文件标识所对应的待部署节点标识更新为可用状态，以使待部署节点中的待部署文件能被下载。
