1.使用ansible建立一個redis例項

2.部署redis_exporter
docker版部署

docker run -d --name redis_exporter -e REDIS_ADDR="redis://192.168.20.157:6379"  -e REDIS_PASSWORD='Senfffc.yl' -p 9121:9121  oliver006/redis_exporter

二進位制部署

wget https://github.com/oliver006/redis_exporter/releases/download/v1.12.1/redis_exporter-v1.12.1.linux-amd64.tar.gz
 


tar -zxvf   redis_exporter-v1.12.1.linux-amd64.tar.gz

./redis_exporter -redis.addr=192.168.20.157:6379 -redis.password='Senfffc.yl' -web.listen-address=192.168.20.157:9121

注意密碼中有點等特殊字元,需要使用 '' .

三訪問:

5.在k8s上,新建endpoint service servicemonitor

cat redis-monitor.yaml

apiVersion: v1
kind: Endpoints
metadata:
  name: redis
 
-metrics
  namespace: monitoring
  labels:
    k8s-app: redis-metrics
subsets:
- addresses:
    - ip: 192.168.20.157
  ports:
  - name: redis-exporter
    port: 9121
    protocol: TCP
---
apiVersion: v1
kind: Service
metadata:
  name: redis-metrics
  namespace: monitoring
  labels:
    k8s-app: redis-metrics
spec:
  type: ClusterIP
  clusterIP: None
  ports:
  
 
- name: redis-exporter
    port: 9121
    protocol: TCP
---
apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: redis-metrics
  namespace: monitoring
  labels:
    app: redis-metrics
    k8s-app: redis-metrics
    prometheus: kube-prometheus
    release: kube-prometheus
spec:
  endpoints:
  - port: redis-exporter
    interval: 15s
  selector:
    matchLabels:
      k8s-app: redis-metrics
  namespaceSelector:
    matchNames:
    - monitoring

6.k8s執行yaml檔案

kubectl create -f  redis-monitor.yaml

7. granfana配置
