k8s部署zabbix監(jiān)控系統(tǒng)

zabbix簡(jiǎn)介

十多年的噶爾網(wǎng)站建設(shè)經(jīng)驗(yàn)，針對(duì)設(shè)計(jì)、前端、開發(fā)、售后、文案、推廣等六對(duì)一服務(wù)，響應(yīng)快，48小時(shí)及時(shí)工作處理。全網(wǎng)營(yíng)銷推廣的優(yōu)勢(shì)是能夠根據(jù)用戶設(shè)備顯示端的尺寸不同，自動(dòng)調(diào)整噶爾建站的顯示方式，使網(wǎng)站能夠適用不同顯示終端，在瀏覽器中調(diào)整網(wǎng)站的寬度，無(wú)論在任何一種瀏覽器上瀏覽網(wǎng)站，都能展現(xiàn)優(yōu)雅布局與設(shè)計(jì)，從而大程度地提升瀏覽體驗(yàn)。成都創(chuàng)新互聯(lián)從事“噶爾網(wǎng)站設(shè)計(jì)”,“噶爾網(wǎng)站推廣”以來(lái)，每個(gè)客戶項(xiàng)目都認(rèn)真落實(shí)執(zhí)行。

       Zabbix 是一種網(wǎng)絡(luò)監(jiān)視、管理系統(tǒng)，基于 Server-Client 架構(gòu)。可用于監(jiān)視各種網(wǎng)絡(luò)服務(wù)、服務(wù)器和網(wǎng)絡(luò)機(jī)器等狀態(tài)。Zabbix 使用 MySQL、PostgreSQL、SQLite、Oracle 或 IBM DB2 儲(chǔ)存資料。Server 端基于 C語(yǔ)言、Web 前端則是基于 PHP 所制作的。Zabbix 可以使用多種方式監(jiān)視。可以只使用 Simple Check 不需要安裝 Client 端，亦可基于 SMTP 或 HTTP 等各種協(xié)定做死活監(jiān)視。在客戶端如 UNIX、Windows 中安裝 Zabbix Agent 之后，可監(jiān)視 CPU 負(fù)荷、網(wǎng)絡(luò)使用狀況、硬盤容量等各種狀態(tài)。而就算沒(méi)有安裝 Agent 在監(jiān)視對(duì)象中，Zabbix 也可以經(jīng)由 SNMP、TCP、ICMP檢查，以及利用 IPMI、SSH、telnet 對(duì)目標(biāo)進(jìn)行監(jiān)視。另外，Zabbix 包含 XMPP 等各種 Item 警示功能。

zabbix k8s部署

  • 部署mysql（采用hostpath做數(shù)據(jù)持久化）

      1.創(chuàng)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(chuàng)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(chuàng)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(chuàng)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
