配置环境变量
在“我的电脑”上点击右键，选择菜单中的“属性"，点击属性对话框上的高级页签，点击”环境变量"按钮，在系统变量列表里双击“Path”变量，在变量值后输入安装的Cygwin的bin目录，例如：D:\hadoop\cygwin64\bin
安装sshd服务
双击桌面上的Cygwin图标，启动Cygwin，执行ssh-host-config -y命令
ps：cgywin ssh-host-config -y命令 报错处理 原因 权限不足无法设置密码，在这里我*处为我设置的密码
方法 右键以管理员身份打开获取权限

$ ssh-host-config -y
*** Info: Generating missing SSH host keys
*** Query: Overwrite existing /etc/ssh_config file? (yes/no) yes
*** Info: Creating default /etc/ssh_config file
*** Query: Overwrite existing /etc/sshd_config file? (yes/no) yes
*** Info: Creating default /etc/sshd_config file
*** Info: StrictModes is set to \'yes\' by default.
*** Info: This is the recommended setting, but it requires that the POSIX
*** Info: permissions of the user\'s home directory, the user\'s .ssh
*** Info: directory, and the user\'s ssh key files are tight so that
*** Info: only the user has write permissions.
*** Info: On the other hand, StrictModes don\'t work well with default
*** Info: Windows permissions of a home directory mounted with the
*** Info: \'noacl\' option, and they don\'t work at all if the home
*** Info: directory is on a FAT or FAT32 partition.
*** Query: Should StrictModes be used? (yes/no) yes
*** Info: Privilege separation is set to \'sandbox\' by default since
*** Info: OpenSSH 6.1. This is unsupported by Cygwin and has to be set
*** Info: to \'yes\' or \'no\'.
*** Info: However, using privilege separation requires a non-privileged account
*** Info: called \'sshd\'.
*** Info: For more info on privilege separation read /usr/share/doc/openssh/README.privsep.
*** Query: Should privilege separation be used? (yes/no) yes
*** Info: Note that creating a new user requires that the current account have
*** Info: Administrator privileges. Should this script attempt to create a
*** Query: new local account \'sshd\'? (yes/no) yes
*** Info: Updating /etc/sshd_config file
*** Query: Do you want to install sshd as a service?
*** Query: (Say "no" if it is already installed as a service) (yes/no) yes
*** Query: Enter the value of CYGWIN for the daemon: []
*** Info: On Windows Server 2003, Windows Vista, and above, the
*** Info: SYSTEM account cannot setuid to other users -- a capability
*** Info: sshd requires. You need to have or to create a privileged
*** Info: account. This script will help you do so.
*** Info: It\'s not possible to use the LocalSystem account for services
*** Info: that can change the user id without an explicit password
*** Info: (such as passwordless logins [e.g. public key authentication]
*** Info: via sshd) when having to create the user token from scratch.
*** Info: For more information on this requirement, see
*** Info: https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-nopasswd1
*** Info: If you want to enable that functionality, it\'s required to create
*** Info: a new account with special privileges (unless such an account
*** Info: already exists). This account is then used to run these special
*** Info: servers.
*** Info: Note that creating a new user requires that the current account
*** Info: have Administrator privileges itself.
*** Info: No privileged account could be found.
*** Info: This script plans to use \'cyg_server\'.
*** Info: \'cyg_server\' will only be used by registered services.
*** Query: Create new privileged user account \'DESKTOP-JFLT9DK\cyg_server\' (Cygwin name: \'cyg_server\')? (yes/no) yes
*** Info: Please enter a password for new user cyg_server. Please be sure
*** Info: that this password matches the password rules given on your system.
*** Info: Entering no password will exit the configuration.
*** Query: Please enter the password:
*** Query: Please enter the password:
*** Query: Reenter:
*** Info: User \'cyg_server\' has been created with password \'*\'.
*** Info: If you change the password, please remember also to change the
*** Info: password for the installed services which use (or will soon use)
*** Info: the \'cyg_server\' account.
*** Info: The sshd service has been installed under the \'cyg_server\'
*** Info: account. To start the service now, call `net start sshd\' or
*** Info: `cygrunsrv -S sshd\'. Otherwise, it will start automatically
*** Info: after the next reboot.
*** Info: Host configuration finished. Have fun!
最后结果 Have fun！
