ssh免密登陆 -- win10连接虚拟机linux

方法

1. 分别在win10和Linux上生成密钥:

ssh-keygen -t rsa

win10的路径: C:\Users\用户名\.ssh\
Linux的路径: /root/.ssh

2. 将win10的公钥id_rsa.pub传输到Linux路径下并更名为authorized_keys

# 在win10的终端,下面的IP换成自己虚拟机的IP
 cd  C:\Users\MengC\.ssh>
 scp .\id_rsa.pub [email protected]:/root/.ssh/authorized_keys

源代码

1. Linux

[root@rac1 ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
# 直接三个回车得到一个类似这样的图

使用

利用windows terminal远程连接虚拟机

打开软件 -> 打开设置 -> 添加新的配置文件 -> 新建空配置文件
