systemctl daemon-reload

systemctl start CloudCore

将KubeEdge云组件设置为开机自启动，命令如下：

#systemctl enable CloudCore

（2）安装KubeEdge的边缘组件

1）编译KubeEdge的边缘组件源码。

下载KubeEdge源码，命令如下：

#git clone GitHub.com/KubeEdge/Ku… KubeEdge

在编译之前确保gcc已经安装，命令如下：

#gcc --version

通过编译源码获得KubeEdge的边缘组件，命令如下：

#cd KubeEdge

#make all WHAT=EdgeCore

编译成功之后，会在./edge下生成可执行文件EdgeCore，将其复制到/usr/bin下即可。

2）从KubeEdge的云组件节点复制Certificates，命令如下：

#scp -r /etc/KubeEdge root@{KubeEdge edge节点IP}:/etc/KubeEdge

3）在KubeEdge的云组件节点为边缘节点创建node对象资源，命令如下：

#kubectl create -f KubeEdge/build/node.json

node.json具体内容如下所示。

{ "kind": "Node", "apiVersion": "v1", "metadata": { "name": "edge-node", "labels": { "name": "edge-node", "node-role.Kubernetes.io/edge": "" } }}

4)生成和设置KubeEdge边缘组件的配置文件。

使用EdgeCore可以生成最小化配置文件和默认配置文件。

创建配置文件目录，命令如下：

#mkdir -p /etc/KubeEdge/config/

生成最小化配置文件，命令如下：

#EdgeCore –minconfig > /etc/KubeEdge/config/EdgeCore.yaml

生成默认配置文件，命令如下：

EdgeCore –defaultconfig > /etc/KubeEdge/config/EdgeCore.yaml

执行上述命令后，会在/etc/KubeEdge/config下生成EdgeCore.yaml文件。下面对执行EdgeCore生成的默认配置文件EdgeCore.yaml进行说明，具体如下所示。
