Azure IoT Edge 软件包受制于每个包(usr/share/doc/{package-name}LICENSE 目录)中的许可条款。Azure IoT Edge software packages are subject to the license terms located in each package (usr/share/doc/{package-name} or the LICENSE directory). 请在使用包之前阅读许可条款。Read the license terms prior to using a package. 安装和使用包即表示你接受这些条款。Your installation and use of a package constitutes your acceptance of these terms. 如果不同意许可条款,请勿使用该包。If you do not agree with the license terms, do not use that package.

安装容器引擎Install a container engine

Azure IoT Edge 依赖于 OCI 兼容的容器运行时。Azure IoT Edge relies on an OCI-compatible container runtime. 对于生产方案,建议使用基于 Moby 的引擎。For production scenarios, we recommended that you use the Moby-based engine. Moby 引擎是官方唯一支持用于 Azure IoT Edge 的容器引擎。The Moby engine is the only container engine officially supported with Azure IoT Edge. Docker CE/EE 容器映像与 Moby 运行时兼容。Docker CE/EE container images are compatible with the Moby runtime.

更新设备上的包列表。Update package lists on your device.

sudo apt-get update

安装 Moby 引擎。Install the Moby engine.

sudo apt-get install moby-engine

如果在安装 Moby 容器引擎时出现错误,请验证 Linux 内核的 Moby 兼容性。If you get errors when installing the Moby container engine, verify your Linux kernel for Moby compatibility. 有些嵌入式设备制造商寄送的设备映像包含的自定义 Linux 内核没有确保容器引擎兼容所需的功能。Some embedded device manufacturers ship device images that contain custom Linux kernels without the features required for container engine compatibility. 运行以下命令,该命令使用 Moby 提供的 check-config 脚本来检查内核配置:Run the following command, which uses the check-config script provided by Moby, to check your kernel configuration:

curl -sSL https://raw.githubusercontent.com/moby/moby/master/contrib/check-config.sh -o check-config.sh
chmod +x check-config.sh

在该脚本的输出中,检查 Generally NecessaryNetwork Drivers 下的所有项是否都已启用。In the output of the script, check that all items under Generally Necessary and Network Drivers are enabled. 如果缺少某些功能,请启用它们,方法是通过源重新构建内核,然后选择关联的模块,将其包括在相应的内核 .config 中。同样,如果使用内核配置生成器(例如 defconfigmenuconfig),请找到并启用相应的功能,然后以相应方式重新构建内核。If you are missing features, enable them by rebuilding your kernel from source and selecting the associated modules for inclusion in the appropriate kernel .config. Similarly, if you are using a kernel configuration generator like defconfig or menuconfig, find and enable the respective features and rebuild your kernel accordingly. 部署新修改的内核以后,请再次运行 check-config 脚本,验证是否已成功启用所有必需功能。Once you have deployed your newly modified kernel, run the check-config script again to verify that all the required features were successfully enabled.

安装 IoT Edge 安全守护程序Install the IoT Edge security daemon

IoT Edge 安全守护程序提供和维护 IoT Edge 设备上的安全标准。The IoT Edge security daemon provides and maintains security standards on the IoT Edge device. 守护程序在每次开机时启动,并通过启动 IoT Edge 运行时的其余部分来启动设备。The daemon starts on every boot and bootstraps the device by starting the rest of the IoT Edge runtime.

这些部分中的步骤表示在具有 Internet 连接的设备上安装最新版本的典型过程。The steps in these section represent the typical process to install the latest version on a device that has internet connection. 如果需要安装特定版本(如预发行版)或需要在脱机状态下安装,请按照下一部分中的脱机或特定版本安装步骤进行操作。If you need to install a specific version, like a pre-release version, or need to install while offline, follow the Offline or specific version installation steps in the next section.

更新设备上的包列表。Update package lists on your device.

sudo apt-get update

查看可用的 IoT Edge 版本。Check to see which versions of IoT Edge are available.

apt list -a iotedge

如果要安装最新版本的安全守护程序,请使用以下命令,该命令还会安装最新版本的 libiothsm-std 包:If you want to install the most recent version of the security daemon, use the following command that also installs the latest version of the libiothsm-std package:

sudo apt-get install iotedge

如果要安装特定版本的安全守护程序,请从 apt 列表输出中指定该版本。If you want to install a specific version of the security daemon, specify the version from the apt list output. 还要为 libiothsm-std 包指定同一版本,否则将安装其最新版本。Also specify the same version for the libiothsm-std package, which otherwise would install its latest version. 例如,以下命令将安装最新版本 1.0.8 版本:For example, the following command installs the most recent version of the 1.0.8 release:

sudo apt-get install iotedge=1.0.8* libiothsm-std=1.0.8*

如果你要安装的版本未列出,请按照下一部分中的脱机或特定版本安装步骤进行操作。If the version that you want to install isn't listed, follow the Offline or specific version installation steps in the next section. 此部分说明了如何将 IoT Edge 安全守护程序的任何之前版本或候选发布版本作为目标。That section shows you how to target any previous version of the IoT Edge security daemon, or release candidate versions.

现在容器引擎和 IoT Edge 运行时已安装在设备上,你可开始下一步操作,即向 IoT 中心注册你的设备并使用其云标识和身份验证信息设置设备。Now that the container engine and the IoT Edge runtime are installed on your device, you're ready for the next step, which is to register your device with IoT Hub and set up the device with its cloud identity and authentication information.
