[CloudNative：Kubernetes&高可用叢集.V03] [Applications.CloudNative] [|雲端計算|K8S|叢集搭建-高可用叢集-實現過程介紹/初始化和部署Keepalived/] [部署haproxy和docker等元件/部署master1節點初始化/部署master2和node節點|]

一、所有節點安裝Docker/kubeadm/kubelet(Kubernetes預設CRI容器執行時為Docker因此先安裝Docker

### --- 安裝Docker

[root@k8s-master1 ~]#  wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
[root@k8s-master1 ~]#  wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
[root@k8s-node1 ~]#    wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo

[root@k8s-master1 ~]# yum -y install docker-ce-18.06.1.ce-3.el7
[root@k8s-master2 ~]# yum -y install docker-ce-18.06.1.ce-3.el7
[root@k8s-node1 ~]# yum -y install docker-ce-18.06.1.ce-3.el7

[root@k8s-master1 ~]# systemctl enable docker && systemctl start docker
[root@k8s-master2 ~]# systemctl enable docker && systemctl start docker
[root@k8s-node1 ~]# systemctl enable docker && systemctl start docker

[root@k8s-master1 ~]# docker --version
Docker version 18.06.1-ce, build e68fc7a
 
[root@k8s-master2 ~]# docker --version
Docker version 18.06.1-ce, build e68fc7a

[root@k8s-node1 ~]# docker --version
Docker version 18.06.1-ce, build e68fc7a

[root@k8s-master1 ~]#  cat > /etc/docker/daemon.json << EOF
> {
>   "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"]
> }
> EOF

[root@k8s-master2 ~]#  cat > /etc/docker/daemon.json << EOF
> {
>   "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"]
> }
> EOF

[root@k8s-node1 ~]#  cat > /etc/docker/daemon.json << EOF
> {
>   "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"]
> }
> EOF

[root@k8s-master1 ~]# systemctl restart docker.service
[root@k8s-master2 ~]# systemctl restart docker.service
[root@k8s-node1 ~]# systemctl restart docker

二、新增阿里雲YUM軟體源

### --- 新增阿里雲YUM軟體源

[root@k8s-master1 ~]#  cat > /etc/yum.repos.d/kubernetes.repo << EOF
> [kubernetes]
> name=Kubernetes
> baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
> enabled=1
> gpgcheck=0
> repo_gpgcheck=0
> gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
> EOF

[root@k8s-master2 ~]#  cat > /etc/yum.repos.d/kubernetes.repo << EOF
> [kubernetes]
> name=Kubernetes
> baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
> enabled=1
> gpgcheck=0
> repo_gpgcheck=0

> gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
> EOF
[root@k8s-node1 ~]#  cat > /etc/yum.repos.d/kubernetes.repo << EOF
> [kubernetes]
> name=Kubernetes
> baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
> enabled=1
> gpgcheck=0
> repo_gpgcheck=0
> gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
> EOF

三、安裝kubeadm，kubelet和kubectl（所有節點）

### --- 安裝kubeadm，kubelet和kubectl（所有節點）
~~~     由於版本更新頻繁，這裡指定版本號部署：

[root@k8s-master1 ~]# yum install -y kubelet-1.16.3 kubeadm-1.16.3 kubectl-1.16.3
[root@k8s-master1 ~]# systemctl enable kubelet
[root@k8s-master2 ~]# yum install -y kubelet-1.16.3 kubeadm-1.16.3 kubectl-1.16.3
[root@k8s-master2 ~]# systemctl enable kubelet
[root@k8s-node1 ~]# yum install -y kubelet-1.16.3 kubeadm-1.16.3 kubectl-1.16.3^C
[root@k8s-node1 ~]# systemctl enable kubelet
