一、Prometheus监控部署

1、下载部署文件

# 使用此链接下载后解压即可
wget https://github.com/prometheus-operator/kube-prometheus/archive/refs/heads/release-0.13.zip

2、根据k8s集群版本获取不同的kube-prometheus版本部署

https://github.com/prometheus-operator/kube-prometheus/tree/release-0.13

3、解压下载好的文件

unzip kube-prometheus-release-0.13.zip
kube-prometheus-release-0.13 # 解压后得到一个目录

4、在执行create前需要修改以下三个文件内容

prometheus-service.yaml
alertmanager-service.yaml
grafana-service.yaml

4.1、需要在service文件中添加type类型为NodePort

cat prometheus-service.yaml 
apiVersion: v1
kind: Service
metadata:labels:app.kubernetes.io/component: prometheusapp.kubernetes.io/instance: k8sapp.kubernetes.io/name: prometheusapp.kubernetes.io/part-of: kube-prometheusapp.kubernetes.io/version: 2.46.0name: prometheus-k8snamespace: monitoring
spec:type: NodePort  # 添加此行即可，grafana和alertmanager修改方式相同ports:- name: webport: 9090targetPort: web- name: reloader-webport: 8080targetPort: reloader-webselector:app.kubernetes.io/component: prometheusapp.kubernetes.io/instance: k8sapp.kubernetes.io/name: prometheusapp.kubernetes.io/part-of: kube-prometheussessionAffinity: ClientIP

5、进入kube-prometheus-release-0.13 目录

# 进入到 /root/kube-prometheus-release-0.13/manifests/setup 此目录执行创建命令
cd /root/kube-prometheus-release-0.13/manifests/setup # 此目录会创建自定义资源类型
kubectl create -f .  # 使用.表示执行此目录下的所有文件
cd /root/kube-prometheus-release-0.13/manifests #此目录是创建prometheus和grafana的主要yaml文件目录
kubectl create -f .  # 使用.表示执行此目录下的所有文件

6、查看pod运行状态

# 出现下面内容说明pod正常运行
kubectl get pod -n monitoring
NAME                                   READY   STATUS    RESTARTS      AGE
alertmanager-main-0                    2/2     Running   0             41m
alertmanager-main-1                    2/2     Running   0             41m
alertmanager-main-2                    2/2     Running   0             41m
blackbox-exporter-6cfc4bffb6-wp2wm     3/3     Running   0             41m
grafana-748964b847-w4hht               1/1     Running   0             41m
kube-state-metrics-6b4d48dcb4-2cfmm    3/3     Running   0             41m

node-exporter-zth9n                    2/2     Running   0             59m
prometheus-adapter-79c588b474-njqtv    1/1     Running   0             43m
prometheus-adapter-79c588b474-r6z49    1/1     Running   0             43m
prometheus-k8s-0                       2/2     Running   0             42m
prometheus-k8s-1                       2/2     Running   0             42m
prometheus-operator-68f6c79f9d-m8wqq   2/2     Running   0             44m

7、查看svc信息

kubectl get svc -n monitoring
NAME                    TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)                         AGE
alertmanager-main       ClusterIP   10.101.105.4    <none>        9093/TCP,8080/TCP               66m
alertmanager-operated   ClusterIP   None            <none>        9093/TCP,9094/TCP,9094/UDP      64m
blackbox-exporter       ClusterIP   10.101.98.31    <none>        9115/TCP,19115/TCP              66m

kube-state-metrics      ClusterIP   None            <none>        8443/TCP,9443/TCP               66m
node-exporter           ClusterIP   None            <none>        9100/TCP                        66m
prometheus-adapter      ClusterIP   10.109.49.125   <none>        443/TCP                         66m
prometheus-k8s          NodePort    10.98.19.241    <none>        9090:32326/TCP,8080:30435/TCP   66m
prometheus-operated     ClusterIP   None            <none>        9090/TCP                        64m

8、至此kube-prometheus监控部署完成
9、使用NodePort方式登录prometheus控制台查看监控节点是否正常

说明：里面都为up说明监控正常
10、使用grafana图形化展示
10.1、grafana初始账号密码为 admin/admin
10.2、添加数据源（此处数据源为prometheus）


10.3、选择数据源为prometheus

10.4、填写数据源名称和地址

10.5、填写完下拉进行测试

11、添加模版


12、grafana图形化展示如下
模板编号 15661

模板编号1860
