一.集群环境
主机名 | 角色 | 工作负载 |
cloud | 云端 | K8s，docker，cloudcore |
edge | 边缘端 | docker，edgecore |
二.系统配置
2.1网络参数配置
cat >> /etc/hosts << EOF

2.2关闭防火墙并禁用开机启动
systemctl stop firewalld & systemctl disable firewalld
2.3永久禁用SELinux
sed -i 's/SELINUX=permissive/SELINUX=disabled/' /etc/sysconfig/selinux
2.4关闭swap分区
sed -ri 's/.*swap.*/#&/' /etc/fstab
2.6设置主机名
hostnamectl set-hostname edge
reboot
三、安装docker
3.1添加阿里云docker仓库
yum -y install yum-utils
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache
3.2安装docker
yum install docker-ce -y
3.3启动Docker服务并激活开机启动
systemctl start docker & systemctl enable docker
3.4测试docker
docker run hello-world
3.5添加docker国内镜像加速
创建或修改 /etc/docker/daemon.json 文件，修改为如下形式
{
"registry-mirrors": [
"https://registry.docker-cn.com",
"http://hub-mirror.c.163.com",
"https://docker.mirrors.ustc.edu.cn"
]
}
重启docker
systemctl restart docker
四、安装keadm
wget https://github.com/kubeedge/kubeedge/releases/download/v1.5.0/keadm-v1.5.0-linux-amd64.tar.gz
tar zxvf keadm-v1.5.0-linux-amd64.tar.gz
cd keadm-v1.5.0-linux-amd64/keadm/
cp keadm /usr/local/sbin
五、加入cloud节点
keadm join --cloudcore-ipport=云端ip:10000 --kubeedge-version=版本号 --token=获取的token
