安装文本编辑器 VIM

sudo apt install vim -y

编辑sshd_config配置文件

sudo vim /etc/ssh/sshd_config

• 找到 #PermitRootLogin prohibit-password 这行注释，并向下复制一行修改为 PermitRootLogin yes 并取消注释，按esc输入 : 并输入wq回车保存退出。

配置文件修改

保存并退出

查看sshd服务是否起来

sudo systemctl status sshd

使用VS code测试连接

• 输入ssh 服务器用户名@服务器IP地址，按回车输入密码

• 选择一个位置保存SSH配置文件，默认即可

• 输入密码后登录服务器（我这里已经保存过密码了没有弹出输入密码的页面）

以上就已经成功设置好了通过VS code远程登录服务器

免密登录设置

打开管理员: Windows PowerShell

在Windows上生成一个密钥

 ssh-keygen -t rsa -C "[email protected]"

• 按三次回车即可，中途不需要输入任何参数。

PS C:\windows\system32> ssh-keygen -t rsa -C "[email protected]"
Generating public/private rsa key pair.
Enter file in which to save the key (C:\Users\fly/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in C:\Users\fly/.ssh/id_rsa.
Your public key has been saved in C:\Users\fly/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:W1mqJxIx7rKGnb12Nif6/H0TI07vvD1CPrGnsDQm70s [email protected]
The key's randomart image is:
+---[RSA 3072]----+
|                 |
|                 |
|      o     .    |
|     . o   +     |
|      o S +      |
|     . . +  ooo  |
|   o.oo +..Eoooo |
|  . +ooo=oB.=*++ |
|   ...o*o=o=o+Ooo|
+----[SHA256]-----+

把密钥传输到服务器

• 密钥位置 Your public key has been saved in C:\Users\fly/.ssh/id_rsa.pub

• 通过scp把文件传输到服务器，请把“ubuntu”@“43.xxx.xx.xxx”:~ 请把引号的服务器用户名跟IP地址替换为你服务器的信息，输入服务器密码后传输完成。

scp C:\Users\fly/.ssh/id_rsa.pub [email protected]:~
[email protected]'s password:
id_rsa.pub

在服务器上面也生成一个密钥

• 密钥生成跟Windows一样

ssh-keygen -t rsa -C "[email protected]"

ubuntu@VM-20-3-ubuntu:~$ ssh-keygen -t rsa -C "[email protected]"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/ubuntu/.ssh/id_rsa):

+----[SHA256]-----+

• 使用ls 查看密钥位置

ubuntu@VM-20-3-ubuntu:~$ ls
id_rsa.pub

• 把密码使用追加的方式写入authorized_keys 这个配置文件

• 这个文件的位置在cd ~/.ssh/

cat id_rsa.pub >> ~/.ssh/authorized_keys

以上就是就是完整的VS Code通过SSH连接Ubuntu进行远程开发教程。
