linux离线安装docker并启动

bash 复制代码

# 查看压缩包内容（确认包含 docker/dockerd 等二进制文件）
tar -tzf docker-24.0.6.tgz
sudo cp /docker/* /usr/local/bin/

验证是否复制成功

bash 复制代码

# 验证二进制文件是否复制成功
ls -l /usr/local/bin/docker*  # 应看到 docker、dockerd、docker-proxy 等文件

配置docker所需的文件，其中ip地址和路径使用自己的

bash 复制代码

sudo vim /etc/systemd/system/docker.service

bash 复制代码

创建这些东西

bash 复制代码

# 创建 Docker 数据目录（默认 /var/lib/docker，可自定义）
sudo mkdir -p /var/lib/docker
sudo mkdir -p /run/containerd

设置权限

bash 复制代码

# 赋予二进制文件执行权限	
sudo chmod +x /usr/local/bin/docker* /usr/local/bin/containerd* /usr/local/bin/runc

chmod 777 /etc/systemd/system/docker.service

准备启动

bash 复制代码

# 重新加载 systemd 配置
sudo systemctl daemon-reload

# 启动 containerd（先确保依赖正常）
sudo systemctl start containerd

# 启动 Docker
sudo systemctl start docker

# 检查 Docker 状态
sudo systemctl status docker
