编写完成后，用以下命令保存并退出vim编辑器

# 退出vim
:wq!

2.编写启动文件

在目录/etc/systemd/system/下，用以下命令编写启动文件cloudcore.service

# 编写启动文件
vim /etc/systemd/system/cloudcore.service

启动文件内容如下

[Unit]
Description=cloudcore.service
[Service]
Type=simple
ExecStart=/usr/local/bin/cloudcore        # cloudcore二进制文件所处位置
Restart=always        # 重启策略
RestartSec=10        # 重启时间
[Install]
WantedBy=multi-user.target

编写好后，用以下命令退出并保存启动文件

# 退出并保存vim
:wq!

3.编译CloudCore

进入kubeedge项目所在文件夹

# 进入kubeedge目录
cd $GOPATH/src/shangqi-kubeedge

编译CloudCore

# 编译CloudCore
make all WHAT=cloudcore

将编译好的文件发送到指定目录下

# 发送二进制文件
cp _output/local/bin/cloudcore /usr/local/bin

4.二进制启动CloudCore

启动CloudCore

# 启动CloudCore
systemctl start cloudcore

可以通过如下命令检查CloudCore是否启动成功

# 检查CloudCore是否启动成功
systemctl status cloudcore

二、部署边端

1.安装证书

将证书放置在指定目录下

cp register.crt /etc/kubeedge/certs/
cp register.key /etc/kubeedge/certs/
cp server.crt /etc/kubeedge/certs/
cp server.key /etc/kubeedge/certs/

2.配置文件

在边缘端环境下，在目录/etc/kubeedge/config/下有文件edgecore.yaml

# 命令进入edgecore.yaml文件，如果没有vim工具，可以使用vi
vim /etc/kubeedge/config/edgecore.yaml

edgecore.yaml配置如下，其中，第35行的token可以由cloud端获取，使用命令kubectl get secret -nkubeedge tokensecret -o=jsonpath=’{.data.tokendata}’ | base64 -d

# 其中较为重要的配置项都已加上注释
