Vscode Code远程连接的免密登录

打开cmd，输入如下，期间的要求连按三次回车即可。

ssh-keygen -t rsa

结果如下：

Generating public/private rsa key pair.
Enter file in which to save the key (C:Users***/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in C:Users***/.ssh/id_rsa.
Your public key has been saved in C:Users***/.ssh/id_rsa.pub.
The key fingerprint is:
*************************************************************
The key's randomart image is:
+---[RSA 3072]----+

一般在目录C:Users***.ssh生成公钥和私钥，公钥是id_rsa.pub，私钥是id_rsa，打开公钥，复制里面的内容。

在服务器上找到.ssh目录，如果没有，则输入如下命令来生成

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

进入.ssh目录，生成一个authorized_keys文件，将local的公钥复制进去

vim authorized_keys //复制内容，保存退出

加入一行

IdentityFile "C:Users***.sshid_rsa"

重新进行远程连接，无需再输入密码。
