在装完cygwin后我们一般将它添加到win7系统环境变量PATH中：

D:cygwinin;D:cygwinusrsbin;

cygwin编译搭建hadoop环境需要安装的软件包：

1.openssh
2.openssl
3.sed
4.zlib
4.tcp_wrappers
5.diffutils
6.vim
7.subversion

右搖管理员身份运行

cygwin输出的中文部分，显示乱码

右键cygwin图标->Option》text

Locale=（选择default会自动变成）C，,Character Set=GBK=> 结果终于可以正常显示中文了：

$ ssh-host-config

*** 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: Privilege separation is set to yes by default since OpenSSH 3.3.

*** Info: However, this requires a non-privileged account called 'sshd'.

*** Info: For more info on privilege separation read /usr/share/doc/openssh/README.privsep.

*** Query: Should privilege separation be used? (yes/no) no

*** 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: [] ntsec

*** 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: You appear to be running Windows XP 64bit, Windows 2003 Server,

*** Info: or later. On these systems, it's not possible to use the LocalSystem

*** Info: account for services that can change the user id without an

*** Info: explicit password (such as passwordless logins [e.g. public key

*** Info: authentication] via sshd).

*** Info: If you want to enable that functionality, it's required to create

*** Info: a new account with special privileges (unless a similar 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: Do you want to use a different name? (yes/no) no（改名字也可以啊）

*** Query: Create new privileged user account '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: Reenter:

*** Info: User 'cyg_server' has been created with password '123456'.

*** 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: Also keep in mind that the user 'cyg_server' needs read permissions

*** Info: on all users' relevant files for the services running as 'cyg_server'.

*** Info: In particular, for the sshd server all users' .ssh/authorized_keys

*** Info: files must have appropriate permissions to allow public key

*** Info: authentication. (Re-)running ssh-user-config for each user will set

*** Info: these permissions correctly. [Similar restrictions apply, for

*** Info: instance, for .rhosts files if the rshd server is running, etc].

*** 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!

竟然报错啊不爽啊

vi /var/log/sshd.log

Privilege separation user sshd does not exist

说要修改/etc/sshd_config 用vi修改会出现键盘不匹配真尼玛

泽哥及时赶到

vi下面有很多命令

cw修改下一个单词

修改UsePrivilegeSeparation sandbox 为UsePrivilegeSeparation no

：wq 保存搞定！

泽哥太给力了

在windows服务管理器中找到sshd 右键启动显示正在启动
