背景技术Background technique
随着互联网的发展，各种规模的服务器集群在各类企业、单位、数据中心等大量涌现。出于安全考虑，大部分计算集群都会存在管理节点+登录节点+计算节点的拓扑结构。一般而言，登录节点负责用户登录，上传下载文件，编译工具等，会连接到互联网，以便用户进行相应的操作。计算节点则是与互联网隔离开，在集群内网中进行数据的传输，这样有效的解决了出于各种不安全原因的威胁问题。然而，在这种情况下，计算节点则不能访问互联网，进一步导致某些必须联网的操作不能成功，带来了极大的不变。With the development of the Internet, a large number of server clusters of various sizes have emerged in various enterprises, units, and data centers. For security reasons, most computing clusters have a topology of management nodes + login nodes + computing nodes. Generally speaking, the login node is responsible for user login, uploading and downloading files, compiling tools, etc., and will be connected to the Internet so that users can perform corresponding operations. Computing nodes are isolated from the Internet, and data transmission is carried out in the cluster intranet, which effectively solves the threat problems caused by various insecure reasons. However, in this case, the computing nodes cannot access the Internet, which further leads to the failure of some operations that must be connected to the Internet, which brings about great changes.
目前，当计算节点需要进行互联网访问时，一般是由人工手动去机房连接外网网线，而目前大部分服务器集群都统一在机房或数据中心进行管理，倘若其数量超过10台，进行人工操作会消耗大量的人力资源；同时也会造成时间浪费，降低工作效率。At present, when a computing node needs to access the Internet, it is generally manually connected to the external network cable in the computer room. At present, most server clusters are managed in the computer room or data center. If the number exceeds 10, manual operation will be difficult. It consumes a lot of human resources; at the same time, it will also cause a waste of time and reduce work efficiency.
因此，如何提供一种解决上述问题的技术方案，是本领域技术人员亟待解决的问题。Therefore, how to provide a technical solution to solve the above problems is an urgent problem to be solved by those skilled in the art.

具体的，由于要实现集群内网对外网的访问，主要在于实现计算节点对外网的访问，因此可以先对使用内网的计算节点进行域名解析配置，如配置DNS解析服务器为8.8.8.8。上述计算节点可以对应内网中的各个主机，对各个主机进行域名解析，即将主机的域名映射为相应的IP地址，其中，该IP地址即为上述内网地址。Specifically, since the access to the external network of the cluster internal network is mainly to realize the access of the computing nodes to the external network, it is possible to configure domain name resolution for the computing nodes using the internal network first, such as configuring the DNS resolution server to 8.8.8.8. The above-mentioned computing nodes can correspond to each host in the intranet, and perform domain name resolution on each host, that is, map the domain name of the host to a corresponding IP address, wherein the IP address is the above-mentioned intranet address.
S102：对登录节点进行外网配置；其中，外网配置包括配置内网地址和连接外网接口；S102: Perform external network configuration on the login node; wherein, the external network configuration includes configuring an internal network address and connecting to an external network interface;
具体的，可以对介于计算节点和管理节点中间的登录节点进行外网配置，以便于计算节点对外网进行访问。其中，上述外网配置可以包括为登陆节点配置已获得的内网地址，以及相应的用于进行外网连接的接口。Specifically, an external network configuration may be performed on the login node between the computing node and the management node, so that the computing node can access the external network. Wherein, the above-mentioned external network configuration may include configuring the obtained internal network address for the login node, and the corresponding interface for connecting to the external network.
