zabbix簡介
Zabbix 是一種網絡監視、管理系統，基於 Server-Client 架構。可用於監視各種網絡服務、服務器和網絡機器等狀態。Zabbix 使用 MySQL、PostgreSQL、SQLite、Oracle 或 IBM DB2 儲存資料。Server 端基於 C語言、Web 前端則是基於 PHP 所製作的。Zabbix 可以使用多種方式監視。可以只使用 Simple Check 不需要安裝 Client 端，亦可基於 SMTP 或 HTTP 等各種協定做死活監視。在客戶端如 UNIX、Windows 中安裝 Zabbix Agent 之後，可監視 CPU 負荷、網絡使用狀況、硬盤容量等各種狀態。而就算沒有安裝 Agent 在監視對象中，Zabbix 也可以經由 SNMP、TCP、ICMP檢查，以及利用 IPMI、SSH、telnet 對目標進行監視。另外，Zabbix 包含 XMPP 等各種 Item 警示功能。

實時繪圖
實驗環境

mysql版本8.0.19（官方鏡像）
zabbix k8s部署
部署mysql（採用hostpath做數據持久化）
1.創建pv
vim mysql-pv.yaml
kind: PersistentVolume apiVersion: v1 metadata: name: mysql-pv-volume labels: type: local spec: storageClassName: manual capacity: storage: 20Gi accessModes: - ReadWriteOnce hostPath: path: "/mnt/data" --- apiVersion: v1 kind: PersistentVolumeClaim metadata: name: mysql-pv-claim spec: storageClassName: manual accessModes: - ReadWriteOnce resources: requests: storage: 20Gi
2.創建mysql配置文件（configMap）
vim mysql-config.yaml
apiVersion: v1 kind: ConfigMap metadata: name: mysql-config data: custom.cnf: | [mysqld] default_storage_engine=innodb skip_external_locking skip_host_cache skip_name_resolve default_authentication_plugin=mysql_native_password
3.創建mysql密碼（secret）
[root@k8s-master-01 mysql]# echo -n password|base64 cGFzc3dvcmQ= vim mysql-secret.yaml
apiVersion: v1 kind: Secret metadata: name: mysql-user-pwd data: mysql-root-pwd: cGFzc3dvcmQ=
4.創建mysql部署文件
vim mysql-deploy.yaml
apiVersion: v1 kind: Service metadata: name: mysql spec: type: NodePort ports: - port: 3306 nodePort: 30006 protocol: TCP targetPort: 3306 selector: app: mysql --- apiVersion: apps/v1 kind: Deployment metadata: name: mysql spec: 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 created service/mysql created deployment.apps/mysql created persistentvolume/mysql-pv-volume created persistentvolumeclaim/mysql-pv-claim created secret/mysql-user-pwd created
部署zabbix-server
vim zabbix-server-deploy.yaml
apiVersion: v1 kind: Service metadata: name: zabbixserver spec: type: NodePort ports: - port: 10051 nodePort: 30051 protocol: TCP targetPort: 10051 selector: app: zabbix-server --- apiVersion: apps/v1 kind: Deployment metadata: name: zabbix-server spec: replicas: 1 selector: matchLabels: app: zabbix-server template: metadata: labels: app: zabbix-server spec: containers: - name: zabbix-server image: zabbix/zabbix-server-mysql imagePullPolicy: IfNotPresent ports: - containerPort: 10051 name: server protocol: TCP readinessProbe: tcpSocket: port: server initialDelaySeconds: 5 periodSeconds: 10 livenessProbe: tcpSocket: port: server initialDelaySeconds: 15 periodSeconds: 20 env: - name: DB_SERVER_HOST value: "mysql" - name: MYSQL_USER value: "zabbix" - name: MYSQL_PASSWORD value: "zabbix" - name: MYSQL_DATABASE value: "zabbix" - name: ZBX_CACHESIZE value: "1024M" - name: ZBX_TRENDCACHESIZE value: "1024M" - name: ZBX_HISTORYCACHESIZE value: "2048M" - name: ZBX_HISTORYINDEXCACHESIZE value: "1024M" - name: ZBX_STARTTRAPPERS value: "5" - name: ZBX_STARTPREPROCESSORS value: "10" - name: ZBX_STARTDBSYNCERS value: "10" - name: DB_SERVER_PORT value: "3306" - name: zabbix-agent image: zabbix/zabbix-agent imagePullPolicy: Always ports: - containerPort: 10050 name: zabbix-agent env: - name: ZBX_HOSTNAME value: "Zabbix server" - name: ZBX_SERVER_HOST value: "127.0.0.1" - name: ZBX_PASSIVE_ALLOW value: "true" - name: ZBX_STARTAGENTS value: "3" - name: ZBX_TIMEOUT value: "10" securityContext: privileged: true
部署zabbix-web
vim zabbix-web.yaml
apiVersion: v1 kind: Service metadata: name: zabbix-web spec: type: NodePort ports: - port: 80 protocol: TCP nodePort: 30080 targetPort: 80 selector: app: zabbix-web --- apiVersion: apps/v1 kind: Deployment metadata: name: zabbix-web spec: 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"
使用kubectl命令及以上yaml文件部署
[root@k8s-master-01 zabbix]# kubectl apply -f ./ service/zabbixserver created deployment.apps/zabbix-server created service/zabbix-web created deployment.apps/zabbix-web created
