[CloudNative：KuberNetes&二進位制部署.V04] [Applications.KuberNetes] [|DevOps|k8s|**3節點**|二進位制1.20||基本元件安裝|——|docker-ce|etcd|kubernetes|git切換分支|]
一、基本元件安裝
### --- docker-ce安裝：Docker安裝 ~~~ # 所有節點安裝Docker-ce 19.03 [root@k8s-master01 ~]# yum install docker-ce-19.03.* -y
### --- 更改docker的啟動引數為systemd
~~~ # 溫馨提示：由於新版kubelet建議使用systemd，所以可以把docker的CgroupDriver改成systemd
[root@k8s-master01 ~]# mkdir /etc/docker
[root@k8s-master01 ~]# cat > /etc/docker/daemon.json <<EOF
{
"exec-opts": ["native.cgroupdriver=systemd"]
}
EOF~~~ # 所有節點設定開機自啟動Docker： [root@k8s-master01 ~]# systemctl daemon-reload && systemctl enable --now docker
二、基本元件安裝：k8s及etcd
### --- 下載k8s及etcd版本包
~~~ # 下載k8s版本包
[root@k8s-master01 ~]# wget https://dl.k8s.io/v1.20.6/kubernetes-server-linux-amd64.tar.gz~~~ # 下載etcd版本包 ~~~ 注：以下操作都在master01執行 ~~~ 注：注意目前版本是1.20.0學員安裝時需要下載最新的1.20.x版本：https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.20.md ~~~ 注：開啟頁面後點擊：CHANGELOG——>找到對應版本——>CHANGELOG-1.20.md——>檢視版本——>選擇：Server binaries——>選擇：kubernetes-server-linux-amd64.tar.gz——>END [root@k8s-master01 ~]# wget https://github.com/etcd-io/etcd/releases/download/v3.4.13/etcd-v3.4.13-linux-amd64.tar.gz
### --- 解壓kubernetes及etcd版本包
~~~ # 解壓kubernetes版本包
[root@k8s-master01 ~]# tar -xf kubernetes-server-linux-amd64.tar.gz --strip-components=3 -C /usr/local/bin kubernetes/server/bin/kube{let,ctl,-apiserver,-controller-manager,-scheduler,-proxy}~~~ # 解壓etcd版本包
[root@k8s-master01 ~]# tar -zxvf etcd-v3.4.13-linux-amd64.tar.gz --strip-components=1 -C /usr/local/bin etcd-v3.4.13-linux-amd64/etcd{,ctl}
etcd-v3.4.13-linux-amd64/etcdctl
etcd-v3.4.13-linux-amd64/etcd### --- 版本檢視
~~~ # 檢視kubernetes版本包
[root@k8s-master01 ~]# kubelet --version
Kubernetes v1.20.6~~~ # 檢視etcd版本包
[root@k8s-master01 ~]# etcdctl version
etcdctl version: 3.4.13
API version: 3.4### --- 將元件傳送到其它部署節點
~~~ # 定義變數
[root@k8s-master01 ~]# MasterNodes='k8s-node01 k8s-node02'
[root@k8s-master01 ~]# WorkNodes='k8s-node01 k8s-node02'~~~ # 將元件傳送到其它節點
[root@k8s-master01 ~]# for NODE in $MasterNodes; do echo $NODE; scp /usr/local/bin/kube{let,ctl,-apiserver,-controller-manager,-scheduler,-proxy} $NODE:/usr/local/bin/; scp /usr/local/bin/etcd* $NODE:/usr/local/bin/; done

kube-proxy 100% 38MB 54.3MB/s 00:00
kubelet 100% 109MB 1.6MB/s 01:06
kube-proxy 三、k8s資源包下載及部署配置
### --- k8s資源包官方地址k8s github : https://github.com/kubernetes/kubernetes/
~~~ # 所有節點建立/opt/cni/bin目錄
[root@k8s-master01 ~]# mkdir -p /opt/cni/bin### --- k8s-master01下下載kubernetes版本包
~~~ # 下載版本包
[root@k8s-master01 ~]# cd /root/ ; git clone https://github.com/dotbalo/k8s-ha-install.git
