windows使用python脚本实现ssh-copy-id免密钥ssh登录linux

1 windows 安装openssh

2 打开cmd,运行命令行 ssh-keygen -t rsa 

3 进入用户名/.ssh文件夹

4 使用ptyhon 同步 公钥 id_rsa.pub至linux服务器

 python ssh-copy-id.py -i :c:/users/{根换自己当前登录用户}/.ssh/id_rsa.pub root@192.168.56.101

5 按提示要求输入linux密码2次就可以完成windows授权,再次使用 ssh root@192.xx.xx.xx 就可以直接登录了

　　ps:如果直接 python ssh-copy-id.py root@192.168.56.101 会提示找不到公钥文件

"""ssh-copy-id for Windows.
Example usage: python ssh-copy-id.py ceilfors@my-remote-machine
This script is dependent on msysgit by default as it requires scp and ssh.
For convenience you can also try that comes http://bliker.github.io/cmder/.
