k8s部署zabbix监控系统

zabbix简介

Zabbix 是一种网络监视、管理系统，基于 Server-Client 架构。可用于监视各种网络服务、服务器和网络机器等状态。Zabbix 使用 MySQL、PostgreSQL、SQLite、Oracle 或 IBM DB2 储存资料。Server 端基于 C语言、Web 前端则是基于 PHP 所制作的。Zabbix 可以使用多种方式监视。可以只使用 Simple Check 不需要安装 Client 端，亦可基于 SMTP 或 HTTP 等各种协定做死活监视。在客户端如 UNIX、Windows 中安装 Zabbix Agent 之后，可监视 CPU 负荷、网络使用状况、硬盘容量等各种状态。而就算没有安装 Agent 在监视对象中，Zabbix 也可以经由 SNMP、TCP、ICMP检查，以及利用 IPMI、SSH、telnet 对目标进行监视。另外，Zabbix 包含 XMPP 等各种 Item 警示功能。

zabbix k8s部署

• 部署mysql（采用hostpath做数据持久化）

1.创建pv

vim mysql-pv.yaml

kind: PersistentVolumeapiVersion: v1metadata:  name: mysql-pv-volume  labels:    type: localspec:  storageClassName: manual  capacity:    storage: 20Gi  accessModes:    - ReadWriteOnce  hostPath:    path: "/mnt/data"---apiVersion: v1kind: PersistentVolumeClaimmetadata:  name: mysql-pv-claimspec:  storageClassName: manual  accessModes:    - ReadWriteOnce  resources:    requests:      storage: 20Gi

2.创建mysql配置文件（configMap）

• （猜你喜欢：zabbix监控k8s出现的pod error status的解决方法）

vim mysql-config.yaml

apiVersion: v1kind: ConfigMapmetadata:  name: mysql-configdata:  custom.cnf: |    [mysqld]    default_storage_engine=innodb    skip_external_locking    skip_host_cache    skip_name_resolve    default_authentication_plugin=mysql_native_password

3.创建mysql密码（secret）

[root@k8s-master-01 mysql]# echo -n password|base64cGFzc3dvcmQ=vim mysql-secret.yaml

apiVersion: v1kind: Secretmetadata:  name: mysql-user-pwddata:  mysql-root-pwd: cGFzc3dvcmQ=

4.创建mysql部署文件

vim mysql-deploy.yaml

apiVersion: v1kind: Servicemetadata:  name: mysqlspec:  type: NodePort  ports:  - port: 3306    nodePort: 30006    protocol: TCP    targetPort: 3306   selector:    app: mysql---apiVersion: apps/v1kind: Deploymentmetadata:  name: mysqlspec:  replicas: 1  selector:    matchLabels:      app: mysql  strategy:    type: Recreate  template:    metadata:      labels:        app: mysql    spec:      containers:      - image: mysql        name: mysql        imagePullPolicy: IfNotPresent        env:        - name: MYSQL_ROOT_PASSWORD          valueFrom:            secretKeyRef:              name: mysql-user-pwd              key: mysql-root-pwd        ports:        - containerPort: 3306          name: mysql        volumeMounts:        - name: mysql-config          mountPath: /etc/mysql/conf.d/        - name: mysql-persistent-storage          mountPath: /var/lib/mysql        - name: timezone          mountPath: /etc/localtime      volumes:      - name: mysql-config        configMap:          name: mysql-config      - name: timezone        hostPath:          path: /usr/share/zoneinfo/Asia/Shanghai      - name: mysql-persistent-storage        persistentVolumeClaim:          claimName: mysql-pv-claim

5.使用kubectl命令及以上yaml文件部署mysql

[root@k8s-master-01 mysql]# kubectl apply -f ./      configmap/mysql-config createdservice/mysql createddeployment.apps/mysql createdpersistentvolume/mysql-pv-volume createdpersistentvolumeclaim/mysql-pv-claim createdsecret/mysql-user-pwd created

• 部署zabbix-server

• 部署zabbix-web

vim zabbix-web.yaml

apiVersion: v1kind: Servicemetadata:  name: zabbix-webspec:  type: NodePort  ports:  - port: 80    protocol: TCP    nodePort: 30080    targetPort: 80  selector:    app: zabbix-web---apiVersion: apps/v1kind: Deploymentmetadata:  name: zabbix-webspec:  replicas: 2  selector:    matchLabels:      app: zabbix-web  template:    metadata:      labels:        app: zabbix-web    spec:      containers:      - image: zabbix/zabbix-web-nginx-mysql        name: zabbix-web        imagePullPolicy: IfNotPresent        ports:        - containerPort: 80          name: web          protocol: TCP        env:        - name: DB_SERVER_HOST          value: "mysql"        - name:  ZBX_SERVER_HOST          value: "zabbixserver"        - name: MYSQL_USER          value: "zabbix"        - name: MYSQL_PASSWORD          value: "zabbix"        - name: TZ          value: "Asia/Shanghai"
