介绍 CTyunOS
天翼云操作系统 CTyunOS 是基于欧拉开源操作系统(openEuler,简称“欧拉”)开发的,欧拉操作系统是华为基于 CentOS 开发的。2019年9月,华为宣布 EulerOS 开源,开源名称为 openEuler(开源欧拉)。EulerOS 支持 AArch64(鲲鹏)处理器、容器虚拟化技术,是一个面向企业级的通用服务器架构平台。华为的鸿蒙是手机手表的操作系统,面向C端。而欧拉是电脑服务器的操作系统,是面向B端。
CTyunOS 操作系统基于 openEuler 20.03 LTS 版本自主研发的。CTyunOS 3 是 CTyunOS 在2023年4月发布的最新版本,上游采用了openEuler社区发布的长期稳定版本 openEuler 22.03 LTS SP1作为基线,针对云计算、云原生场景进行了深度的开发,目前在天翼云上已经可以开通该操作系统的弹性云主机。
