容器化部署Prometheus

Posted 2022-12-05 givenchy_yzl

使用kubernetes部署Prometheus

#下载Prometheus包并解压
[root@k8s-master-01 ~]# wget https://github.com/prometheus-operator/kube-prometheus/archive/refs/tags/v0.7.0.tar.gz
[root@k8s-master-01 ~]# tar -xf v0.7.0.tar.gz 

# 安装Prometheus
[root@k8s-master-01 ~]# cd kube-prometheus-0.7.0/manifests/setup
[root@k8s-master-01 setup]# kubectl apply -f ./
[root@k8s-master-01 setup]# cd ..
[root@k8s-master-01 ~/kube-prometheus-0.7.0/manifests]# kubectl apply -f ./

#查看Prometheus的服务
[root@k8s-master-01 ~]# kubectl get svc -n monitoring

# 为Prometheus和grafana创建ingress
[root@k8s-master-01 ingress]# cat > ingress.yaml << EOF
kind: Ingress
apiVersion: networking.k8s.io/v1
metadata:
  name: prometheus
  namespace: monitoring
spec:
  rules:
    - host: "prometheus.test.com"
      http:
        paths:
          - backend:
              service:
                name: prometheus-k8s
                port: 
                  number: 9090
            path: "/"
            pathType: Prefix
---            
kind: Ingress
apiVersion: networking.k8s.io/v1
metadata:
  name: grafana
  namespace: monitoring
spec:
  rules:
    - host: "grafana.test.com"
      http:
        paths:
          - backend:
              service:
                name: grafana
                port:
                  number: 3000
            path: "/"
            pathType: Prefix
EOF

[root@k8s-master-01 ~]# kubectl apply -f ingress/ingress.yaml

[root@k8s-master-01 ~]# kubectl get ingress -n monitoring 

将prometheus.test.com，grafana.test.com加入本地解析
浏览器访问
prometheus.test.com:30080
grafana.test.com:30080

添加数据源后---->+ -----> import----> 搜索框输入官方GUI码
GUI码来源：grafana.com---->grafana---->dashborad---->数据源选择 Prometheus---->搜索kubernetes---->点击模板---->copy id to clipboard
成功：如下图

携带metircs接口的服务
1、jiang

[root@web02 ~]# cat /prometheus_mysql/.my.cnf
host=192.168.13.11
port=mysql的端口
[client]
user=mysql_monitor
password=abc123

Prometheus监控Java
1、修改pom.xml
