PowerShell一般是指Windows PowerShell，它是一种跨平台的任务自动化解决方案，由命令行shell、脚本语言和配置管理框架组成。本文将介绍下如何在Debian服务器上安装PowerShell。

Debian服务器安装PowerShell有多种方法，例如在GitHub官网的PowerShell页面下载适合Debian服务器的相关安装包，然后进行安装；为了简化安装和更新，我们也可以登录到Debian服务器，然后通过包存储库安装PowerShell，Debian将APT（包工具）用作包管理器。

1、通过包存储库在Debian 11上安装PowerShell

# Install system components
sudo apt update && sudo apt install -y curl gnupg apt-transport-https

# Import the public repository GPG keys
curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add –

# Register the Microsoft Product feed
sudo sh -c ‘echo “deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-debian-bullseye-prod bullseye main” > /etc/apt/sources.list.d/microsoft.list’

# Install PowerShell
sudo apt update && sudo apt install -y powershell

# Start PowerShell
pwsh

2、通过包存储库在Debian 10上安装PowerShell

# Download the Microsoft repository GPG keys
wget https://packages.microsoft.com/config/debian/10/packages-microsoft-prod.deb

# Register the Microsoft repository GPG keys
sudo dpkg -i packages-microsoft-prod.deb

# Update the list of products
sudo apt-get update

# Install PowerShell
sudo apt-get install -y powershell

# Start PowerShell
pwsh

3、通过包存储库在Debian 9上安装PowerShell

# Install system components
sudo apt-get update
sudo apt-get install -y curl gnupg apt-transport-https

# Import the public repository GPG keys
curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add –

# Register the Microsoft Product feed
sudo sh -c ‘echo “deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-debian-stretch-prod stretch main” > /etc/apt/sources.list.d/microsoft.list’

# Update the list of products
sudo apt-get update

# Install PowerShell
sudo apt-get install -y powershell

# Start PowerShell
pwsh

我们以超级用户身份注册Microsoft存储库后，可以通过sudo apt-get install powershell命令更新PowerShell。
