openEuler（https://openeuler.org/zh/）是什么呢？按照官方的说法：“openEuler是一个开源、免费的Linux发行版平台，将通过开放的社区形式与全球的开发者共同构建一个开放、多元和架构包容的软件生态体系。”
按照尝新的步骤，查看文档、快速入门、下载安装、尝试使用、安装软件，来试一下这个东西。
1、查看文档
主页在openEuler（https://openeuler.org/zh/）。
- 源码：https://gitee.com/openeuler
- 安装：https://openeuler.org/zh/docs/20.03_LTS/docs/Releasenotes/release_notes.html

总体上看，文档应该刚刚开始，玩的人还比较少。
2、快速入门
进入主页（https://openeuler.org/zh/），点击快速入门，然后：
3、下载安装
下载下来，试一试。官方网站的链接如下：
- openEuler 20.03 LTS All Releases>>
- The openEuler 20.03 LTS version is a standard release version that meets open scenario requirements, which has a lifecycle of four years.
- Download ISO:Link
- Lifecycle:Link
- Submit issues:Link
3.1 最新的20.03版本下载链接如下（镜像比较大！）：
- Index of /openEuler-20.03-LTS/ISO/x86_64/

| openEuler-20.03-LTS-x86_64-dvd.iso.sha256sum | 101 B | 2020-Mar-26 14:49 |
3.2 已经有arm64的版本如下（也比较大）：
- Index of /openEuler-20.03-LTS/ISO/aarch64/
| File Name ↓ | File Size ↓ | Date ↓ |
|---|---|---|
| Parent directory/ | - | - |
| openEuler-20.03-LTS-aarch64-dvd.iso | 4.3 GiB | 2020-Mar-26 14:46 |
| openEuler-20.03-LTS-aarch64-dvd.iso.sha256sum | 102 B | 2020-Mar-26 14:48 |
| openEuler-20.03-LTS-debuginfo-aarch64-dvd.iso | 10.9 GiB | 2020-Mar-26 14:48 |
| openEuler-20.03-LTS-debuginfo-aarch64-dvd.iso.s..> | 112 B | 2020-Mar-26 14:48 |

| openEuler-20.03-LTS-everything-aarch64-dvd.iso...> | 113 B | 2020-Mar-26 14:49 |
3.3 快速下载ISO for X64版本：
wget -c https://repo.openeuler.org/openEuler-20.03-LTS/ISO/x86_64/openEuler-20.03-LTS-everything-x86_64-dvd.iso 因为比较大，我使用-c参数来支持断点续传。刚开始速度比较快，然后很快降速，下载需要比较长的时间。
4、尝试使用
下一步使用virtualbox来进行试验，虽然上面的文档只有在Windows下的案例，但使用MacOS和Linux应该也是一样。我使用MacOS下的VirtualBox来进行测试。创建虚拟机、然后安装。
5、安装软件
然后是登录进去，安装新的软件源，更新系统。
