2.检查node节点状态

[root@k8s-master ~]# kubectl get nodes -owideNAME         STATUS   ROLES                  AGE     VERSION   INTERNAL-IP     EXTERNAL-IP   OS-IMAGE                KERNEL-VERSION          CONTAINER-RUNTIMEk8s-master   Ready    control-plane,master   2d16h   v1.23.1   192.168.3.201   <none>        CentOS Linux 7 (Core)   3.10.0-957.el7.x86_64   containerd://1.6.6k8s-node01   Ready    <none>                 2d16h   v1.23.1   192.168.3.202   <none>        CentOS Linux 7 (Core)   3.10.0-957.el7.x86_64   containerd://1.6.6k8s-node02   Ready    <none>                 2d16h   v1.23.1   192.168.3.203   <none>        CentOS Linux 7 (Core)   3.10.0-957.el7.x86_64   containerd://1.6.6


二、配置nfs共享存储

1.安装nfs

yum install -y nfs-utils


2.创建共享目录

mkdir -p /nfs/data


3.配置共享目录

echo "/nfs/data/ *(insecure,rw,sync,no_root_squash)" > /etc/exports


4.启动相关服务

    systemctl enable rpcbindsystemctl enable nfs-serversystemctl start rpcbind


    5.使配置生效

    exportfs -r


    6.查看nfs

    [root@k8s-master ~]# exportfs/nfs/data       <world>


    7.其他节点检查nfs共享

      [root@k8s-node01 ~]#  showmount -e 192.168.3.201Export list for 192.168.3.201:/nfs/data *


      三、安装zabbix-mysql

      1.编写zabbix-mysql的yaml文件

        [root@k8s-master zabbix]# cat zabbix_mysql.yaml ---apiVersion: v1kind: PersistentVolumemetadata:  name: zabbixdb-pvspec:  capacity:   #创建存储的大小    storage: 10Gi  volumeMode: Filesystem  #存储的类型  accessModes:    - ReadWriteOnce  persistentVolumeReclaimPolicy: Recycle  nfs:    path: /nfs/data/zabbix    server: 192.168.3.201  mountOptions:    - hard    - nfsvers=4.1---apiVersion: v1kind: PersistentVolumeClaimmetadata:  name: zabbixdb-pvc  namespace: zabbixspec:  accessModes:    - ReadWriteOnce  volumeMode: Filesystem   #存储类型 ，块存储Block  resources:    requests:      storage: 8Gi---apiVersion: apps/v1kind: Deploymentmetadata:  labels:    app: zabbixdb  name: zabbixdb  namespace: zabbixspec:  replicas: 1  selector:    matchLabels:      app: zabbixdb  strategy: {}  template:    metadata:      labels:        app: zabbixdb    spec:      volumes:      - name: zabbixdb-data        persistentVolumeClaim:          claimName: zabbixdb-pvc      containers:      - image: mysql:8.0        name: mysql        ports:        - name: mysql          containerPort: 3306          protocol: TCP        volumeMounts:        - name: zabbixdb-data          mountPath: /var/lib/mysql        env:        - name: MYSQL_DATABASE          value: 'zabbix'        - name: MYSQL_USER          value: 'zabbix'        - name: MYSQL_PASSWORD          value: 'zabbix'        - name: MYSQL_ROOT_PASSWORD          value: 'zabbix'        resources:           requests:             cpu: 0.1             memory: 128Mi          limits:             cpu: 0.3             memory:  512Mi---

        2.创建命名空间

          [root@k8s-master zabbix]# kubectl create namespace zabbixnamespace/zabbix created


          3.创建zabbix数据库

            kubectl apply -f zabbix_mysql.yaml


            4.检查pod状态

              [root@k8s-master zabbix]# kubectl get pods -n zabbix NAME                        READY   STATUS    RESTARTS   AGEzabbixdb-69b7cd8dff-jnpjd   1/1     Running   0          11m


              四、检查zabbix数据库的service域名

              1.运行测试pod

              [root@k8s-master ~]# kubectl run busybox --image=busybox:1.28 -- sleep 3600pod/busybox created


              2.进入busybox的pod

              [root@k8s-master ~]# kubectl exec -it busybox -- /bin/sh/ #


              3.查看域名解析

                [root@k8s-master ~]# kubectl exec -it busybox -- /bin/sh/ # nslookup zabbixdb.zabbix.svc.cluster.localServer:    10.96.0.10Address 1: 10.96.0.10 kube-dns.kube-system.svc.cluster.local

Name:      zabbixdb.zabbix.svc.cluster.localAddress 1: 10.96.1.99 zabbixdb.zabbix.svc.cluster.local/ #


                五、安装zabbix-server

                [root@k8s-master zabbix]# cat zabbix_server.yaml apiVersion: apps/v1kind: Deploymentmetadata:  creationTimestamp: null  labels:    app: zabbix-server  name: zabbix-server  namespace: zabbixspec:  replicas: 1  selector:    matchLabels:      app: zabbix-server  strategy: {}  template:    metadata:      creationTimestamp: null      labels:        app: zabbix-server    spec:      volumes:      - name: zabbix-scripts        hostPath:          path: /usr/lib/zabbix/      - name: zabbix-file        hostPath:          path: /var/lib/zabbix       nodeSelector:        zabbix-server: "true"      hostNetwork: true      containers:      - image: zabbix/zabbix-server-mysql:6.0-ubuntu-latest        name: zabbix-server-mysql        env:        - name: DB_SERVER_HOST          value:  10.96.1.99        - name: MYSQL_USER          value: zabbix        - name: MYSQL_PASSWORD          value: zabbix        resources: {}status: {}


                2.给node02节点打上标签

                [root@k8s-master zabbix]# kubectl label nodes k8s-node02  zabbix-server=truenode/k8s-node02 labeled


                3.安装zabbix-server
