Games101作业0(vscode连接VB虚拟机)

作业0

配置环境:

基本配置在pa0中都有,下面介绍使用vscode连接VB虚拟机快捷开发

vscode连接VB虚拟机

1.用户名

可以看到Username为cs18并非为css180

2.密钥

在window主机生成密钥

ssh-keygen #一路回车

3.VB虚拟机配置ssh

• sshd_config配置

cd /etc/ssh/
vim sshd_config 

复制以下粘贴到文末:

其实主要修改为:

PermitRootLogin yes
PubkeyAuthentication yes
AuthorizedKeysFile      .ssh/authorized_keys .ssh/authorized_keys
PasswordAuthentication yes
PermitEmptyPasswords yes

• 放置公钥 到下面文件 没有就新建

~/.ssh/authorized_keys

• 重启ssh服务

sudo service ssh restart

4.虚拟机网卡

按下图设置后保存

查看地址

ifconfig

复制红线地址

在window cmd下测试连接

 ssh cs18@地址

可进入虚拟机则进入下一步

5.vscode连接

输入

 ssh cs18@地址

如果连接不上则进行 vscode ssh配置

Host 地址
  HostName 地址
  User cs18
  Port 22
  IdentityFile "C:\Users\你的用户名\.ssh\id_rsa"

至此配置完成 可以愉快的在windows上写代码了,与实际没有差异,任何跳转\提示功能健全
