1. SSH禁用密码登录，修改端口

    # 复制公钥到服务器
vi ~/.ssh/authorized_keys
# 修改sshd配置文件
Port 1234
PermitRootLogin prohibit-password
PubkeyAuthentication yes
PasswordAuthentication no
ChallengeResponseAuthentication no
# 重启ssh服务
systemctl restart ssh
service ssh restart

  2. 同步Git公钥

    # 生成SSH密钥对
ssh-keygen -t rsa -b 4096 -C "****@gmail.com"
# 将SSH公钥添加到Git服务
cat ~/.ssh/id_rsa.pub

  3. 安装Docker

    Debian install docker
