cd ~\.ssh\
没有就创建 C:\Users\用户名\.ssh\

notepad.exe .\config
或者
notepad.exe C:\ProgramData\ssh\ssh_config

config格式：

Host 主机名
    HostName IP/domain
    User username
    Port 22

SSH Key

  • 配置本地密钥，已有请忽略

生成密钥
ssh-keygen -t rsa
type .\id_rsa.pub
复制结果

首先ssh -P post username@IP/domain
sudo apt-get/yum install openssh-server
sudo vi /etc/ssh/sshd_config
取消注释（搜索指定行）禁用密码登录，启用密钥登录
sed -i "s/PasswordAuthentication yes/PasswordAuthentication no/g" /etc/ssh/sshd_config
sed -i "s/#PasswordAuthentication yes/PasswordAuthentication no/g" /etc/ssh/sshd_config
echo "" >> /etc/ssh/sshd_config
echo "AllowUsers root" >> /etc/ssh/sshd_config
sed -i "s/#PermitRootLogin yes/PermitRootLogin prohibit-password/g" /etc/ssh/sshd_config
mkdir ~/.ssh && chmod -R 750 ~/.ssh
vi ~/.ssh/authorized_keys
i
把 type .\id_rsa.pub 的结果粘贴进去
:wq
sudo systemctl enable sshd
sudo systemctl restart sshd
接着你就可以 ssh 主机名链接了
