安装依赖工具​

bash复制sudo apt update
sudo apt install -y ca-certificates curl gnupg lsb-release

---

​步骤 3：添加 Docker 官方 GPG 密钥​

bash复制sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

---

​步骤 4：添加 Docker APT 源​

根据你的系统版本选择对应的源（以下以 Ubuntu 为例）：

bash复制echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

如果是 Debian，将 ubuntu替换为 debian：

bash复制echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

---

​步骤 5：安装 Docker 最新版​

bash复制sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

有时操作系统能安装的nginx版本存在漏洞，需要安装最新稳定版本，可用如下方法：

# 把源加入 /etc/apt/sources.list
deb http://nginx.org/packages/mainline/debian bookworm nginx
# 导入gpg key
curl -fsSL https://nginx.org/keys/nginx_signing.key | gpg --dearmor -o /etc/apt/trusted.gpg.d/nginx.gpg
# 更新源及更新nginx
apt update
apt install nginx
