Linux高性能计算集群SSH安全远程登录的研究

Research on SSH Secure Remote Login of Linux High Performance Computing Cluster

高性能计算集群是当前较为先进的计算体系,高性能计算的快速发展已为其他科学技术的发展提供了越来越广的支撑,其安全性显得非常重要。SSH(Secure Shell)作为一种通用的、基于软件的安全访问远程服务器的网络协议,已广泛应用于Linux高性能计算集群,本文以甘肃省计算中心高性能计算集群为实验对象,以OpenSSH为例,介绍了SSH的工作原理,OpenSSH的安装和配置,以及远程登录管理服务器,对于利用SSH远程管理服务器具有一定的指导意义。

High performance computing clusters are currently more advanced computing systems. The rapid development of highperformance computing has provided more and more support for the development of other science and technology,and its security is very important. SSH (Secure Shell) is a general-purpose,software-based network protocol for securely accessing remote servers. It has been widely used in Linux high performance computing clusters. This article takes the high performance computing cluster of Gansu Computing Center as the experimental object. Taking OpenSSH as an example,it introduces the working principle of SSH,the installation and configuration of OpenSSH,and the remote login management server,which have certain guiding significance for remotely managing servers by SSH.
