一、軟件包下載地址
Server包: https://dl.k8s.io/v1.9.6/kubernetes-server-linux-amd64.tar.gz

二、部署master相關組件
1、解壓軟件包

# tar -zxvpf kubernetes-server-linux-amd64.tar.gz 
# cp -r  kubernetes/server/bin/{kube-apiserver,kube-controller-manager,kube-scheduler,kubectl,kube-proxy,kubelet}  /usr/local/sbin/
 

2、生成證書

# cat k8s-csr.json
{
  "CN": "kubernetes",
  "hosts": [
    "127.0.0.1",
    "192.168.115.5",
    "10.254.0.1",
    "kubernetes",
    "kubernetes.default",
    "kubernetes.default.svc",
    "kubernetes.default.svc.cluster",
    "kubernetes.default.svc.cluster.local"
  ],
  "key": {
    "algo": "rsa",
    "size": 2048
  },
  "names": [
    {
      "C": "CN",
      "ST": "FuZhou",
      "L": "FuZhou",
      "O": "k8s",
      "OU": "System"
    }
  ]
}

# cfssl gencert -ca=/etc/ssl/etcd/ca.pem   -ca-key=/etc/ssl/etcd/ca-key.pem   -config=/etc/ssl/etcd/ca-config.json   -profile=kubernetes k8s-csr.json | cfssljson -bare kubernetes

# mkdir /etc/ssl/kubernetes
# mv *.pem /etc/ssl/kubernetes/
 

3、生成token，用於後續node節點加入使用

# head -c 16 /dev/urandom | od -An -t x | tr -d ‘ ‘
3e6916ba861192f279c67d827952ea30

# cat token.csv 
3e6916ba861192f279c67d827952ea30,kubelet-bootstrap,10001,"system:kubelet-bootstrap"

# mv token.csv /etc/kubernetes/

4、配置和啟動api-server

# cat /usr/lib/systemd/system/kube-apiserver.service   
[Unit]
Description=Kubernetes API Server
Documentation=https://github.com/GoogleCloudPlatform/kubernetes
After=network.target

[Service]
ExecStart=/usr/local/sbin/kube-apiserver   --admission-control=NamespaceLifecycle,LimitRanger,ServiceAccount,DefaultStorageClass,ResourceQuota   --advertise-address=192.168.115.5   --bind-address=192.168.115.5   --insecure-bind-address=127.0.0.1   --authorization-mode=RBAC   --runtime-config=rbac.authorization.k8s.io/v1alpha1   --kubelet-https=true --enable-bootstrap-token-auth=true   --token-auth-file=/etc/kubernetes/token.csv   --service-cluster-ip-range=10.254.0.0/16   --service-node-port-range=8400-9000   --tls-cert-file=/etc/ssl/kubernetes/kubernetes.pem   --tls-private-key-file=/etc/ssl/kubernetes/kubernetes-key.pem   --client-ca-file=/etc/ssl/etcd/ca.pem   --service-account-key-file=/etc/ssl/etcd/ca-key.pem   --etcd-cafile=/etc/ssl/etcd/ca.pem   --etcd-certfile=/etc/ssl/kubernetes/kubernetes.pem   --etcd-keyfile=/etc/ssl/kubernetes/kubernetes-key.pem   --etcd-servers=https://192.168.115.5:2379,https://192.168.115.6:2379,https://192.168.115.7:2379   --enable-swagger-ui=true   --allow-privileged=true   --apiserver-count=3   --audit-log-maxage=30   --audit-log-maxbackup=3   --audit-log-maxsize=100   --audit-log-path=/var/lib/audit.log   --event-ttl=1h   --v=2
Restart=on-failure
RestartSec=5
Type=notify
LimitNOFILE=65536

[Install]
WantedBy=multi-user.target

# systemctl daemon-reload
# systemctl start  kube-apiserver
# systemctl status kube-apiserver
 

5、配置和啟動 kube-controller-manager

# cat /usr/lib/systemd/system/kube-controller-manager.service    
[Unit]
Description=Kubernetes Controller Manager
Documentation=https://github.com/GoogleCloudPlatform/kubernetes

[Service]
ExecStart=/usr/local/sbin/kube-controller-manager   --address=127.0.0.1   --master=http://127.0.0.1:8080   --allocate-node-cidrs=true   --service-cluster-ip-range=10.254.0.0/16   --cluster-cidr=172.30.0.0/16   --cluster-name=kubernetes   --cluster-signing-cert-file=/etc/ssl/etcd/ca.pem   --cluster-signing-key-file=/etc/ssl/etcd/ca-key.pem   --service-account-private-key-file=/etc/ssl/etcd/ca-key.pem   --root-ca-file=/etc/ssl/etcd/ca.pem   --leader-elect=true   --v=2
Restart=on-failure
RestartSec=5

[Install]
WantedBy=multi-user.target

# systemctl  daemon-reload
# systemctl  start kube-controller-manager
# systemctl  status kube-controller-manager

6、配置和啟動 kube-scheduler

# cat /usr/lib/systemd/system/kube-scheduler.service 
[Unit]
Description=Kubernetes Scheduler
Documentation=https://github.com/GoogleCloudPlatform/kubernetes

[Service]
ExecStart=/usr/local/sbin/kube-scheduler   --address=127.0.0.1   --master=http://127.0.0.1:8080   --leader-elect=true   --v=2
Restart=on-failure
RestartSec=5

[Install]
WantedBy=multi-user.target

# systemctl daemon-reload
# systemctl start kube-scheduler

7、驗證master所有組件是否運行正常

8、配置所有組件自動啟動

# systemctl enable kube-apiserver
# systemctl enable kube-controller-manager
# systemctl enable kube-scheduler
