GitHub链接

https://github.com/prometheus-operator/kube-prometheus

根据自己的k8s版本选择对应的版本

# git设置代理
git config --global http.proxy IP地址:端口# 1.27对应的版本为release-0.13
git clone -b release-0.13 https://github.com/prometheus-operator/kube-prometheus.gitcd kube-prometheus/

修改镜像地址

kubectl apply --server-side -f manifests/setup
kubectl wait \--for condition=Established \--all CustomResourceDefinition \--namespace=monitoring
kubectl apply -f manifests/

# 查看是否全部运行

对Etcd集群进行监控（云原生监控）

Etcd的Metrics接口需要https协议访问

# 先获取证书文件目录
grep -E "key-file|cert-file" /etc/kubernetes/manifests/etcd.yamlcurl -s --cert /etc/kubernetes/pki/etcd/server.crt --key /etc/kubernetes/pki/etcd/server.key https://IP地址:2379/metrics -k | tail -1

创建Etcd Service

vim etcd-svc.yaml

apiVersion: v1
kind: Service
metadata:labels:app: etcd-promname: etcd-promnamespace: kube-system
spec:ports:- name: https-metricsport: 2379protocol: TCPtargetPort: 2379selector: # 添加标签选择器component: etcd # 容器etcd的标签type: ClusterIP

ports:- name: https-metricsport: 2379protocol: TCP
endpoints:- addresses:- "YOUR_ETCD_IP01" # Etcd集群的IP地址- "YOUR_ETCD_IP02"- "YOUR_ETCD_IP03"

kubectl apply -f etcd-svc.yaml
kubectl get svc -n kube-system etcd-prom#通过curl测试访问
curl -s --cert /etc/kubernetes/pki/etcd/server.crt --key /etc/kubernetes/pki/etcd/server.key https://CLUSTER-IP:2379/metrics -k | tail -1

创建Etcd证书的Secret

# 创建Etcd证书的Secret
kubectl create secret generic etcd-ssl --from-file=/etc/kubernetes/pki/etcd/ca.crt --from-file=/etc/kubernetes/pki/etcd/server.crt --from-file=/etc/kubernetes/pki/etcd/server.key -n monitoring# 将证书挂载到容器里
kubectl edit prometheus k8s -n monitoring

# 检查是否挂载成功
kubectl exec -n monitoring prometheus-k8s-0 -c prometheus -- ls /etc/prometheus/secrets/etcd-ssl/

创建Etcd ServiceMonitor

vim servicemonitor.yaml

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:name: etcdnamespace: monitoringlabels:app: etcd
spec:jobLabel: k8s-appendpoints:- interval: 30sport: https-metrics  # 这个port对应 Service.spec.ports.namescheme: httpstlsConfig:caFile: /etc/prometheus/secrets/etcd-ssl/ca.crt #证书路径certFile: /etc/prometheus/secrets/etcd-ssl/server.crtkeyFile: /etc/prometheus/secrets/etcd-ssl/server.keyinsecureSkipVerify: true  # 关闭证书校验selector:matchLabels:app: etcd-prom  # 跟Service的lables保持一致namespaceSelector:matchNames:- kube-system

kubectl create -f servicemonitor.yaml

kubectl get svc,pod

创建用户和权限

kubectl exec -it mysqlpod名称 -- bash

CREATE USER 'exporter'@'%' IDENTIFIED BY 'exporter';
