OpenSSH的安装及运行

使用powershell安装openSSH

以管理员身份运行powershell，运行以下指令：

 Get-WindowsCapability -Online | Where-Object Name -like 'OpenSSH*'

已安装的服务输出 "Installed"，未安装输出"NotPresent"，如下：

根据需要安装的组件运行以下命令：

# Install the OpenSSH Client
Add-WindowsCapability -Online -Name OpenSSH.Client~~~~0.0.1.0

# Install the OpenSSH Server
Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0

如安装成功，控制台将输出以下内容：

Path          :
Online        : True
RestartNeeded : False

重启电脑添加服务，启动并配置OpenSSH服务

管理员身份运行powershell，然后运行以下命令启动sshd service：

# Start the sshd service
Start-Service sshd

# OPTIONAL but recommended:
Set-Service -Name sshd -StartupType 'Automatic'

# Confirm the Firewall rule is configured. It should be created automatically by setup. Run the following to verify
if (!(Get-NetFirewallRule -Name "OpenSSH-Server-In-TCP" -ErrorAction SilentlyContinue | Select-Object Name, Enabled)) {
    Write-Output "Firewall Rule 'OpenSSH-Server-In-TCP' does not exist, creating it..."
    New-NetFirewallRule -Name 'OpenSSH-Server-In-TCP' -DisplayName 'OpenSSH Server (sshd)' -Enabled True -Direction Inbound -Protocol TCP -Action Allow -LocalPort 22
} else {
    Write-Output "Firewall rule 'OpenSSH-Server-In-TCP' has been created and exists."
}

客户机登录测试（此部分运行在客户机），此部分过于简单，不做详细演示

ssh username@ip
#输入密码

在服务器上部署rsa密钥

客户机生成密钥（此部分运行在客户机）

ssh-keygen -t rsa
#一路enter

此时客户机目录 ~/.ssh下将生成id_rsa和id_rsa.pub，将id_rsa.pub改名为administrators_authorized_keys，粘贴至服务器的C:\ProgramData\ssh目录

修改服务器的ssh配置文件

#目录C:\ProgramData\ssh\sshd_config

内容如下

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.

#AddressFamily any

# The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2

# For this to work you will also need host keys in %programData%/ssh/ssh_known_hosts

Match Group administrators
       AuthorizedKeysFile __PROGRAMDATA__/ssh/administrators_authorized_keys

管理员身份运行powershell，提升文件administrators_authorized_keys权限

icacls.exe "C:\ProgramData\ssh\administrators_authorized_keys" /inheritance:r /grant "Administrators:F" /grant "SYSTEM:F"

客户机以rsa连接服务器

ssh -i ~\.ssh\id_rsa username@ip

windows下开启ssh服务
