vscode ssh 免密登录

1. 需要关闭密码；好像密码登录会优先于rsa
2. 要开启RSA，以及授权authorized_keys文件?

# 本地电脑VS Code安装插件 Remote Development
# 在本地电脑.ssh目录下生成公钥(id_rsa.pub)和私钥(id_rsa)
cd ~/.ssh
ssh-keygen
# 生成公钥和私钥，添加公钥authorized_keys，并复制到服务器上
cat id_rsa.pub >> authorized_keys
ls  # =>查看确保生成功authorized_keys
scp authorized_keys name@server_ip:/home/name/.ssh
# 在服务器上更改私钥权限。打开SSH配置文件，禁用密码登陆(选项)。最后重启ssh服务
cd /home/name/.ssh
sudo chmod 600 authorized_keys
sudo chmod 700 ~/.ssh

sudo nano /etc/ssh/sshd_config
"RSAAuthentication yes
 PubkeyAuthentication yes
 PasswordAuthentication no"

service sshd restart
# 最后修改本机电脑配置ssh文件 vscode的ssh配置那里把密钥文件也一起写上
Host name
  HostName ip
  User username
  IdentityFile /path/.ssh/id_rsa
Host 169.254.xxx.xxx
? HostName 169.254.xxx.xxx
? User zhr
? IdentityFile c:/Users/xxxx/.ssh/id_rsa # 注意这里windows的写法
? ForwardX11 yes
? ForwardX11Trusted yes
? ForwardAgent yes
# 若提示“ Permissions 0644 for ‘/xx/.ssh/id_rsa.pub’ are too open”，使用以下指令更改私钥权限
chmod 0600 ~/.ssh/id_rsa
# 若提示“Enter passphrase for key”，执行下面代码
ssh-add -K ~/.ssh/id_rsa

# permission denied (publickey)
sudo nano /etc/ssh/sshd_config
"RSAAuthentication yes # 这个忘记写了
 PubkeyAuthentication yes
 PasswordAuthentication no"
 # 还添加了
 AuthenticationFile .ssh/authorized_keys_pc # 最后才通过了
