k8s外安裝mysql

配置MySQL Exporter採集MySQL監控資料

建立yaml檔案：vim mysql-exporter.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mysql-exporter
  namespace: monitoring
spec:
  replicas: 1
  selector:
    matchLabels:
      k8s-app: mysql-exporter
  template:
    metadata:
      labels:
        k8s-app: mysql-exporter
    spec:
      containers:
      - name: mysql-exporter
        image: registry.cn-chengdu.aliyuncs.com/qzcsbj/mysqld-exporter:v0.12.1
        env:
         - name: DATA_SOURCE_NAME
           value: "root:123456@(192.168.117.160:3306)/"
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 9104
---
apiVersion: v1
kind: Service
metadata:
  name: mysql-exporter
  namespace: monitoring
  labels:
    k8s-app: mysql-exporter
spec:
  type: ClusterIP
  selector:
    k8s-app: mysql-exporter
  ports:
  - name: mysql-exporter-api
    port: 9104
    protocol: TCP

建立exporter：kubectl create -f mysql-exporter.yaml

檢視資源：kubectl get -f mysql-exporter.yaml

檢視pod：kubectl get po -n monitoring |grep mysql-exporter

檢視svc：kubectl get svc -n monitoring |grep mysql-exporter

檢視是否獲取到監控資料：curl 10.109.182.129:9104/metrics | grep max_connections

prometheus中檢視資料

檢視prometheus的svc：kubectl get svc -n monitoring | grep prometheus

請求：http://192.168.117.161:30576

target中，prometheus自動發現了mysql

config中，自動生成了配置檔案

查詢資料：max_connections（要手動輸入，不能複製貼上）

mysql_global_variables_max_connections

grafana中檢視資料

檢視grafana的svc：kubectl get svc -n monitoring | grep grafana

請求：http://192.168.117.161:31239/

匯入模板：https://grafana.com/grafana/dashboards/7362

然後選擇資料來源

效果
