k8s部署zabbix監(jiān)控系統(tǒng)-創(chuàng)新互聯(lián)

zabbix簡(jiǎn)介

目前創(chuàng)新互聯(lián)建站已為上千家的企業(yè)提供了網(wǎng)站建設(shè)、域名、網(wǎng)站空間、網(wǎng)站托管維護(hù)、企業(yè)網(wǎng)站設(shè)計(jì)、莊河網(wǎng)站維護(hù)等服務(wù)，公司將堅(jiān)持客戶導(dǎo)向、應(yīng)用為本的策略，正道將秉承"和諧、參與、激情"的文化，與客戶和合作伙伴齊心協(xié)力一起成長(zhǎng)，共同發(fā)展。

Zabbix 是一種網(wǎng)絡(luò)監(jiān)視、管理系統(tǒng)，基于 Server-Client 架構(gòu)?？捎糜诒O(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?？梢灾皇褂?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.yamlkind: 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）

（猜你喜歡：zabbix監(jiān)控k8s出現(xiàn)的pod error status的解決方法）

vim mysql-config.yamlapiVersion: 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.yamlapiVersion: 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.yamlapiVersion: 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.yamlapiVersion: 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.yamlapiVersion: 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
