一、openEuler操作系统介绍
openEuler是一款开源、免费的操作系统,由openEuler社区运作。当前openEuler内核源于Linux,支持鲲鹏及其它多种处理器,能够充分释放计算芯片的潜能,是由全球开源贡献者构建的高效、稳定、安全的开源操作系统,适用于数据库、大数据、云计算、人工智能等应用场景。
openEuler的前身是运行在华为公司通用服务器上的操作系统EulerOS。EulerOS是一款基于Linux内核(目前是基于Linux4.19版本的内核)的开源操作系统,支持X86和ARM等多种处理器架构,伴随着华为公司鲲鹏芯片的研发,EulerOS 理所当然地成为与鲲鹏芯片配套的软件基础设施。2019年底,EulerOS被正式推送至开源社区,更名为openEuler。openEuler也是一个创新的平台,鼓励任何人在该平台上提出新想法、开拓新思路、实践新方案。所有个人开发者、企业和商业组织都可以使用。
二、openEuler操作系统使用
GUI:图形用户界面。用户界面的所有元素图形化,主要使用鼠标作为输入工具,使用按钮、菜单、对话框等进行交互,追求易用。
CLI:命令行界面。用户界面字符化,使用键盘作为输 入工具,输入命令、选项、参数执行程序,追求高效。
openEuler 20.03 LTS版本暂无图形界面。
Linux主要有两种登录方式,本地登录和远程登录。本地登录类似类似于打开自己电脑或者服务器直接接显示器的方式,一个典型的Linux系统将运行六个虚拟控制台,可以通过Ctrl+Alt+F[1-6]在六个虚拟控制台之间进行切换。默认情况下openEuler支持远程登录,可以通过putty、xshell等工具远程登录到openEuler。
三、openEuler登录使用
