kubernetes 环境装置Nacos集群

1.nfs服务器配置

#所有k8s节点执行yum install -y nfs-utilsmkdir -p /usr/local/nacos/nfs-sharemkdir -p /usr/local/nacos/mysql-slavemkdir -p /usr/local/nacos/mysql-masterchmod a+rw /usr/local/nacos#增加nacos、mysql-master 、mysql-slave 长久化文件夹vi /etc/exports/usr/local/nacos/mysql-master  *(insecure,rw,async,no_root_squash)/usr/local/nacos/mysql-slave  *(insecure,rw,async,no_root_squash)/usr/local/nacos/nfs-share  *(insecure,rw,async,no_root_squash)systemctl restart rpcbind.servicesystemctl restart nfs-server.serviceshowmount -e kipnode1

2.部署nfs

下载nacos k8s部署代码

git clone https://github.com/nacos-group/nacos-k8s.git

创立nacos 命名空间

kubectl create namespace nacos

创立角色

cd nacos-k8sNS=$(kubectl config get-contexts|grep -e "^\*" |awk '{print $5}')NAMESPACE=${NS:-nacos}sed -i'' "s/namespace:.*/namespace: $NAMESPACE/g" ./deploy/nfs/rbac.yamlkubectl create -f deploy/nfs/rbac.yaml

创立 ServiceAccount 和部署 NFS-Client Provisioner

批改deployment.yaml

apiVersion: v1kind: ServiceAccountmetadata:  name: nfs-client-provisioner---kind: DeploymentapiVersion: extensions/v1beta1metadata:  name: nfs-client-provisionerspec:  replicas: 1  strategy:    type: Recreate  template:    metadata:      labels:        app: nfs-client-provisioner    spec:      serviceAccount: nfs-client-provisioner      containers:      - name: nfs-client-provisioner        image: quay.io/external_storage/nfs-client-provisioner:latest        volumeMounts:        - name: nfs-client-root          mountPath: /persistentvolumes        env:        - name: PROVISIONER_NAME          value: fuseim.pri/ifs        - name: NFS_SERVER          value: kipnode1        - name: NFS_PATH          value: /usr/local/nacos/nfs-share      volumes:      - name: nfs-client-root        nfs:          server: kipnode1          path: /usr/local/nacos/nfs-share
kubectl create -f deploy/nfs/deployment.yaml -n nacos

创立 NFS StorageClass

kubectl create -f deploy/nfs/class.yaml -n nacos

验证NFS部署胜利

kubectl get pod -l app=nfs-client-provisioner -n nacos

3.部署数据库

部署主库

批改 mysql-master-nfs.yaml nfs地位

apiVersion: v1kind: ReplicationControllermetadata:  name: mysql-master  labels:    name: mysql-masterspec:  replicas: 1  selector:    name: mysql-master  template:    metadata:      labels:        name: mysql-master    spec:      containers:      - name: master        image: nacos/nacos-mysql-master:latest        ports:        - containerPort: 3306        volumeMounts:        - name: mysql-master-data          mountPath: /var/lib/mysql        env:        - name: MYSQL_ROOT_PASSWORD          value: "root"        - name: MYSQL_DATABASE          value: "nacos_devtest"        - name: MYSQL_USER          value: "nacos"        - name: MYSQL_PASSWORD          value: "nacos"        - name: MYSQL_REPLICATION_USER          value: 'nacos_ru'        - name: MYSQL_REPLICATION_PASSWORD          value: 'nacos_ru'      volumes:      - name: mysql-master-data        nfs:          server: kipnode1          path: /usr/local/nacos/mysql-master---apiVersion: v1kind: Servicemetadata:  name: mysql-master  labels:    name: mysql-masterspec:  ports:  - port: 3306    targetPort: 3306  selector:    name: mysql-master
kubectl create -f deploy/mysql/mysql-master-nfs.yaml -n nacos

部署从库

批改 mysql-slave-nfs.yaml nfs地位

apiVersion: v1kind: ReplicationControllermetadata:  name: mysql-slave  labels:    name: mysql-slavespec:  replicas: 1  selector:    name: mysql-slave  template:    metadata:      labels:        name: mysql-slave    spec:      containers:      - name: slave        image: nacos/nacos-mysql-slave:latest        ports:        - containerPort: 3306        volumeMounts:        - name: mysql-slave-data          mountPath: /var/lib/mysql        env:        - name: MYSQL_ROOT_PASSWORD          value: "root"        - name: MYSQL_REPLICATION_USER          value: 'nacos_ru'        - name: MYSQL_REPLICATION_PASSWORD          value: 'nacos_ru'      volumes:      - name: mysql-slave-data        nfs:          server: kipnode1          path: /usr/local/nacos/mysql-slave---apiVersion: v1kind: Servicemetadata:  name: mysql-slave  labels:    name: mysql-slavespec:  ports:  - port: 3306    targetPort: 3306  selector:    name: mysql-slave
kubectl create -f deploy/mysql/mysql-slave-nfs.yaml -n nacos

4.部署Nacos

批改deploy/nacos/nacos-pvc-nfs.yaml 和数据库配置文件保持一致即可

data:  mysql.master.db.name: "主库名称"  mysql.master.port: "主库端口"  mysql.slave.port: "从库端口"  mysql.master.user: "主库用户名"  mysql.master.password: "主库明码"
kubectl create -f deploy/nacos/nacos-pvc-nfs.yaml -n nacos

应用kubectl scale 对Nacos动静扩容

kubectl scale sts nacos --replicas=3 -n nacos

5.创立ingress

vi ingress/nacos-ingress.yaml

---# 创立Ingress，定义拜访规定 apiVersion: extensions/v1beta1 kind: Ingressmetadata:  name: nacos-headlessspec:  rules:  - host: demo.nacos.com    http:      paths:      - path: /        backend:          serviceName: nacos-headless          servicePort: 8848 
kubectl create -f nacos-ingress.yaml -n nacos
