关于python:SSH免密登陆Win登陆linux

在本地运行 git bash(windows)

ssh-keygen -t rsa -C "xxx@qq.com"

一路回车

Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:/k7eBzEwIUHIjhq09GBEkoRMLKKbCV4XzyhHJ3ffsj0 vansenb@foxmail.com
The key's randomart image is:
+---[RSA 3072]----+
|%O   o o+...     |
|O+. .++o oo      |

查看密钥文件

cat ~/.ssh/id_rsa.pub

从 ssh-rsa 开始，直到集体标识完结，全副复制

登陆到服务器 (linux)，将公钥写入文件

cd ~/.ssh && vim authorized_keys

应用 vim 编辑器关上文件后按 i 键进入编辑模式，应用键盘快捷键 Ctr V 粘贴方才复制的公钥字符串。接着按 ESC 键进入 vim 编辑器的命令行模式，输出 :wq 并回车。
