ice con art get install cas replicat yum 火墻

1、關閉CentOS自帶的防火墻服務： systemctl disable firewalld systemctl stop firewalld 2、安裝etcd和Kubernetes軟件(會自動安裝docker軟件)： yum install -y etcd kubernates 3、修改配置文件： a、docker配置文件/etc/sysconfig/docker，其中OPTIONS的內容設置為 OPTIONS=‘--selinux-enabled=false b、Kubernetes apiserver配置文件/etc/kubernetes/apiserver，把--admission-control參數中的ServiceAccount刪除。 4、按順序啟動各個服務： systemctl start etcd systemctl start docker systemctl start kube-apiserver systemctl start kube-controller-manager systemctl start kube-scheduler systemctl start kubelet systemctl start kube-proxy 5、下載鏡像 docker pull kubeguide/guestbook-redis-slave docker pull kubeguide/guestbook-php-frontend docker pull kubeguide/redis-master 6、 先定義RC來創建pod,然後定義與之關聯的service。 為redis-master服務新建一個名為redis-master-controller.yaml的RC定義文件,內容為: apiVersion: v1 kind: ReplicationController metadata: name: redis-master labels: name: redis-master spec: replicas: 1 selector: name: redis-master template: metadata: labels: name: redis-master spec: containers: - name: master image: kubeguide/redis-master ports: - containerPort: 6379 新建好文件之後執行如下命令: kuberctl create -f redis-master-controller.yaml 刪除：將create換為delete即可。 查看剛剛新建的redis-master： kuberctl get rc 檢查pod信息: kuberctl get pods 7、下面新建與上面建的pod相關聯的service,service對應的文件redis-master-service.yaml,內容如下: apiVersion: v1 kind: Service metadata: name: redis-master labels: name: redis-master spec: ports: - port: 6379 targetPort: 6379 selector: name: redis-master 創建service： kubectl create -f redis-master-service.yaml 查看新建的service: kubectl get services 8、 redis-salve Pod和服務 步驟和redis-master的一樣。 新建文件redis-salve-controller.yaml，內容如下: apiVersion: v1 kind: ReplicationController metadata: name: redis-slave labels: name: redis-slave spec: replicas: 2 selector: name: redis-slave template: metadata: labels: name: redis-slave spec: containers: - name: slave image: kubeguide/guestbook-redis-slave env: - name: GET_HOSTS_FROM value: env ports: - containerPort: 6379 運行kubectl create命令: kubectl create -f redis-salve-controller.yaml 查看RC: kubectl get rc 查看pod: kubectl get pods 9、配置文件redis-salve-service.yaml內容如下: apiVersion: v1 kind: Service metadata: name: redis-slave labels: name: redis-slave spec: ports: - port: 6379 selector: name: redis-slave 創建service： kubectl create -f redis-slave-service.yaml 檢查service： kubectl get services; 10、 創建frontend Pod和服務 文件frontend-controller.yaml內容如下: apiVersion: v1 kind: ReplicationController metadata: name: frontend labels: name: frontend spec: replicas: 3 selector: name: frontend template: metadata: labels: name: frontend spec: containers: - name: frontend image: kubeguide/guestbook-php-frontend env: - name: GET_HOSTS_FROM value: env ports: - containerPort: 80 執行命令kubectl create： kubectl create -f frontend-controller.yaml 檢查RC: kunectl get rc 檢查pod: kubectl get pods 11、文件frontend-service.yaml內容如下: apiVersion: v1 kind: Service metadata: name: frontend labels: name: frontend spec: type: NodePort ports: - port: 80 nodePort: 30001 selector: name: frontend 創建服務: kubectl create -f frontend-service.yaml 檢查service： kubectl get services; 12、 訪問網站 如我的虛擬機IP為192.168.153.46 則瀏覽器訪問: 192.168.153.46:30001
