# Installation Preparations
This section describes the compatibility of the hardware and software and the related configurations and preparations required for the installation.
+
+## Obtaining the Installation Source
+
+Obtain the openEuler release package and verification file before the installation.
+
+Perform the following operations to obtain the openEuler release package:
+
+1. Log in to the [openEuler Community](https://openeuler.org) website.
+2. Click **Download**.
+3. Click the link provided after **Download ISO**. The download list is displayed.
+4. Click **openEuler-20.03-LTS**. The openEuler 20.03 LTS version download list is displayed.
+5. Click **ISO**. The ISO download list is displayed.
+ - **aarch64**: ISO image file of the AArch64 architecture
+ - **x86\_64**: ISO image file of the x86\_64 architecture
+ - **source**: ISO image file of the openEuler source code
+
+6. Select the openEuler release package and verification file to be downloaded based on the architecture of the environment to be installed.
+ - If the AArch64 architecture is used:
+ 1. Click **aarch64**.
+ 2. Click **openEuler-20.03-LTS-aarch64-dvd.iso** to download the openEuler release package to the local host.
+ 3. Click **openEuler-20.03-LTS-aarch64-dvd.iso.sha256sum** to download the openEuler verification file to the local host.
+
+ - If the x86\_64 architecture is used:
+ 1. Click **x86\_64**.
+ 2. Click **openEuler-20.03-LTS-x86\_64-dvd.iso** to download the openEuler release package to the local host.
+ 3. Click **openEuler-20.03-LTS-x86\_64-dvd.iso.sha256sum** to download the openEuler verification file to the local host.
+
+## Release Package Integrity Check
+
+> **NOTE:**
+>This section describes how to verify the integrity of the release package in the AArch64 architecture. The procedure for verifying the integrity of the release package in the x86\_64 architecture is the same.
+
+### Introduction
+
+To prevent the software package from being incompletely downloaded due to network or storage device faults during transmission, you need to verify the integrity of the software package after obtaining it. Only the software packages that pass the verification can be installed.
+
+Compare the verification value recorded in the verification file with the .iso file verification value calculated manually to check whether the software package passes the verification. If the verification values are consistent, the .iso file is not damaged. If they are inconsistent, you can confirm that the file is damaged and you need to obtain the file again.
+
+### Prerequisites
+
+Before verifying the integrity of the release package, you need to prepare the following files:
+
+ISO file: **openEuler-20.03-LTS-aarch64-dvd.iso**
+
+Verification file: **openEuler-20.03-LTS-aarch64-dvd.iso.sha256sum**
+
+### Procedure
+
+To verify the file integrity, perform the following operations:
+
+1. Obtain the verification value in the verification file. Run the following command:
+
+ ```
+ #cat openEuler-20.03-LTS-aarch64-dvd.iso.sha256sum
+ ```
+
+2. Calculate the SHA256 verification value of the file. Run the following command:
+
+ ```
+ #sha256sum openEuler-20.03-LTS-aarch64-dvd.iso
+ ```
+
+ After the command is run, the verification value is displayed.
+
+3. Check whether the values calculated in step 1 and step 2 are consistent.
+
+ If the verification values are consistent, the .iso file is not damaged. If they are inconsistent, you can confirm that the file is damaged and you need to obtain the file again.
+
+## Installation Requirements for PMs
+
+To install the openEuler OS on a PM, the PM must meet the following hardware compatibility and minimum hardware requirements.
+
+### Hardware Compatibility
+
+You need to take hardware compatibility into account during openEuler installation. [Table 1](#table14948632047) describes the types of supported servers.
+
+> **NOTE:**
+>
+>- TaiShan 200 servers are backed by Huawei Kunpeng 920 processors.
+>- Currently, only Huawei TaiShan and FusionServer Pro servers are supported. More servers from other vendors will be supported in the future.

The hard disk supports IDE, SATA, SAS interfaces.
+
+
+
+
+
+## Installation Requirements for VMs
+
+To install the openEuler OS on a VM, the VM must meet the following hardware compatibility and minimum hardware requirements.
+
+### Virtualization Platform Compatibility
+
+When installing openEuler, pay attention to the compatibility of the virtualization platform. Currently, the following virtualization platforms are supported:
+
+- A virtualization platform created by the virtualization components \(openEuler as the host OS and QEMU and KVM provided in the release package\) of openEuler
+- x86 virtualization platform of Huawei public cloud
+
+### Minimum Virtualization Space
+
+[Table 3](#tff48b99c9bf24b84bb602c53229e2541) lists the minimum virtualization space required by openEuler.

介绍安装前需要考虑软硬件兼容性状况，以及相关的配置和准备工作。
+## 获取安装源
+
+在安装开始前，您需要获取openEuler的发布包和校验文件。
+
+请按以下步骤获取openEuler的发布包和校验文件：
+
+1. 登录[openEuler社区](https://openeuler.org)网站。
+2. 单击“下载”。
+3. 单击“获取ISO：”后面的“Link”，显示版本列表。
+4. 单击“openEuler-20.03-LTS”，进入openEuler 20.03 LTS版本下载列表。
+5. 单击“ISO”，进入ISO下载列表。
+ - aarch64：AArch64架构的ISO。
+ - x86\_64：x86\_64架构的ISO。
+ - source：openEuler源码ISO。
+
+6. 根据实际待安装环境的架构选择需要下载的openEuler的发布包和校验文件。
+ - 若为AArch64架构。
+ 1. 单击“aarch64”。
+ 2. 单击“openEuler-20.03-LTS-aarch64-dvd.iso”，将openEuler发布包下载到本地。
+ 3. 单击“openEuler-20.03-LTS-aarch64-dvd.iso.sha256sum”，将openEuler校验文件下载到本地。
+
+ - 若为x86\_64架构。
+ 1. 单击“x86\_64”。
+ 2. 单击“openEuler-20.03-LTS-x86\_64-dvd.iso”，将openEuler发布包下载到本地。
+ 3. 单击“openEuler-20.03-LTS-x86\_64-dvd.iso.sha256sum”，将openEuler校验文件下载到本地。
+
+## 发布包完整性校验
+
+> **说明：**
+>本章节以AArch64架构的发布包完整性校验为例，x86\_64架构的发布包完整性校验的操作方法相同。
+
+### 简介
+
+为了防止软件包在传输过程中由于网络原因或者存储设备原因出现下载不完整的问题，在获取到软件包后，需要对软件包的完整性进行校验，通过了校验的软件包才能部署。
+
+这里通过对比校验文件中记录的校验值和手动方式计算的iso文件校验值，判断软件包是否完成。若两个值相同，说明iso文件完整，否则，iso完整性被破坏，请重新获取iso发布包。
+
+### 前提条件
+
+在校验发布包完整性之前，需要准备如下文件：
+
+iso文件：openEuler-20.03-LTS-aarch64-dvd.iso
+
+校验文件：openEuler-20.03-LTS-aarch64-dvd.iso.sha256sum
+
+### 操作指导
+
+文件完整性校验操作步骤如下：
+
+1. 获取校验文件中的校验值。执行命令如下：
+
+ ```
+ #cat openEuler-20.03-LTS-aarch64-dvd.iso.sha256sum
+ ```
+
+2. 计算文件的sha256校验值。执行命令如下：
+
+ ```
+ #sha256sum openEuler-20.03-LTS-aarch64-dvd.iso
+ ```
+
+ 命令执行完成后，输出校验值。
+
+3. 对比步骤1和步骤2计算的校验值是否一致。
+
+ 如果校验值一致说明iso文件完整性没有破坏，如果校验值不一致则可以确认文件完整性已被破坏，需要重新获取。
+
+## 物理机的安装要求
+
+若需要在物理机环境上安装openEuler操作系统，则物理机需要满足如下的硬件兼容性和最小硬件要求。
+
+### 硬件兼容支持

- **图 7** 安装概览
-
- 1. 选择“软件选择”，设置“软件选择”配置项。
-
- 用户需要根据实际的业务需求，在左侧选择一个“最小安装”，在右侧选择安装环境的附加选项，如[图8](#fig1133717611109)所示。
-
- **图 8** 软件选择
-
- > **说明：**
- >- 在最小安装的环境下，并非安装源中所有的包都会安装。如果用户需要使用的包未安装，可将安装源挂载到本地制作repo源，通过DNF工具单独安装。
- >- 选择“虚拟化主机”时会默认安装虚拟化组件qemu、libvirt、edk2，且可在附件选项处选择是否安装ovs等组件。
-
- 设置完成后，请单击左上角“完成”返回“安装概览”页面。
-
- 2. 选择“安装位置”，设置“安装位置”配置项。
-
- 在安装位置页面中，您可以选择计算机中的本地可用存储设备，也可以通过单击“添加磁盘”，添加指定的附加设备或者网络设备。您还需要进行存储配置以便对系统分区。您可以手动配置分区，也可以选择让安装程序自动分区。如果是在未使用过的存储设备中执行全新安装，或者不需要保留该存储设备中任何数据，建议选择“自动”进行自动分区。如[图9](#fig153381468101)所示。
-
- > **须知：**
- >在选择您需要安装的设备时，建议不要选择NVMe SSD存储介质作为操作系统的安装磁盘。
-
- **图 9** 安装目标位置
-
- > **说明：**
- >- 在进行分区时，出于系统性能和安全的考虑，建议您划分如下单独分区：/boot、/var、/var/log 、/var/log/audit、/home、/tmp。
- >- 系统如果配置了swap分区，当系统的物理内存不够用时，会使用swap分区。虽然 swap分区可以增大物理内存大小的限制，但是如果由于内存不足使用到swap分区，会增加系统的响应时间，性能变差。因此在物理内存充足或者性能敏感的系统中，不建议配置swap分区。
- >- 如果需要拆分逻辑卷组则需要选择“自定义”进行手动分区，并在“手动分区”界面单击“卷组”区域中的“修改”按钮重新配置卷组。
-
- 设置完成后，请单击左上角“完成”返回“安装概览”页面。
-
- 3. 设置其他配置项，其他配置项可以使用默认配置。
-
-3. 单击“开始安装”进行系统安装，如[图10](#fig1717019357392)所示。

-
-4. 设置root密码。
-
- 单击“root密码”，弹出设置密码界面如[图11](#zh-cn_topic_0186390266_zh-cn_topic_0122145909_fig1323165793018)所示，输入密码并再次输入密码进行确认。
-
- > **说明：**
- >root密码需要在安装软件包的同时进行配置，如果不配置该密码则无法完成安装。root账户是用来执行关键系统管理任务，不建议您在日常工作及系统访问时使用root账户。
-
- 用户设置的root密码需要满足如下密码复杂度要求，否则会导致密码设置或用户创建失败。
-
- - 口令长度至少8个字符。
- - 口令至少包含大写字母、小写字母、数字和特殊字符中的任意3种。
- - 口令不能和账号一样。
- - 口令不能使用字典词汇。
- - 查询字典
-
- 在已装好的openEuler环境中，可以通过如下命令导出字典库文件dictionary.txt，用户可以查询密码是否在该字典中。
-
- ```
- cracklib-unpacker /usr/share/cracklib/pw_dict > dictionary.txt
- ```
-
- - 修改字典
- - 修改上面导出的字典文件，执行如下命令更新系统字典库。
-
- ```
- create-cracklib-dict dictionary.txt
- ```
-
- - 在原字典库基础上新增其他字典内容custom.txt。
-
- ```
- create-cracklib-dict dictionary.txt custom.txt
- ```

-5. 创建用户。
-
- 单击“创建用户”，弹出创建用户的界面如[图12](#zh-cn_topic_0186390266_zh-cn_topic_0122145909_fig1237715313319)所示。输入用户名，并设置密码，其中密码复杂度要求与root密码复杂度要求一致。另外您还可以通过“高级”选项设置用户主目录、用户组等，如[图13](#zh-cn_topic_0186390266_zh-cn_topic_0122145909_fig128716531312)所示。
