二  安置kubernetes 1.17.0 2.1 组件

三个节点都需要安置下面三个组件

kubeadm：安置工具，安置后，所有的组件城市以容器的方法运行

kubectl：是一个客户端   

kubelet：运行在node节点，用来启动容器的工具

使用yum安置，使用阿里云的yum源https://developer.aliyun.com/mirror

https://developer.aliyun.com/mirror/kubernetes?spm=a2c6h.13651102.0.0.53322f705Hg6zu

2.2 配置yum源

按照文档，给三台机器配置yum源，安置

cat <<EOF > /etc/yum.repos.d/kubernetes.repo [kubernetes] name=Kubernetes baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/ enabled=1 gpgcheck=1 repo_gpgcheck=1 gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg EOF

目前最新版本是1.17

2.3 安置

[[email protected] ~]# yum install -y kubelet kubeadm kubectl

[[email protected] ~]# yum install -y kubelet kubeadm kubectl

[[email protected] ~]# yum install -y kubelet kubeadm kubectl

[[email protected] ~]# rpm -aq|grep kube

kubeadm-1.17.0-0.x86_64 kubernetes-cni-0.7.5-0.x86_64 kubectl-1.17.0-0.x86_64 kubelet-1.17.0-0.x86_64

[[email protected] ~]#  systemctl enable kubelet && systemctl start kubelet

[[email protected] ~]#  systemctl enable kubelet && systemctl start kubelet

[[email protected] ~]#  systemctl enable kubelet && systemctl start kubelet

2.4 加载内核模块

所有节点操纵
