前置條件
安裝好k8s集群（幾個(gè)節(jié)點(diǎn)都可以，本人為了方便實(shí)驗(yàn)k8s集群只有一個(gè)master節(jié)點(diǎn)），注意prometheus是部署在k8s集群內(nèi)部的，不同于傳統(tǒng)監(jiān)控分為監(jiān)控端和被控端。

二、部署yaml各個(gè)組件
kubectl命令tab補(bǔ)全
[root@k8s-master ~]# yum install -y bash-completion
[root@k8s-master ~]# source <(kubectl completion bash)
2.1 node-exporter.yaml
[root@k8s-master k8s-prometheus-grafana-master]# kubectl apply -f node-exporter.yaml
daemonset.apps/node-exporter created
service/node-exporter created
#因?yàn)橹挥幸粋€(gè)節(jié)點(diǎn)，這里如果有多個(gè)節(jié)點(diǎn)，節(jié)點(diǎn)數(shù)=node-exporterPod數(shù)
[root@k8s-master k8s-prometheus-grafana-master]# kubectl get pod -A | grep node-exporter
kube-system node-exporter-kpdxh 0/1 ContainerCreating 0 28s
[root@k8s-master k8s-prometheus-grafana-master]# kubectl get daemonset -A | grep exporter

[root@k8s-master k8s-prometheus-grafana-master]# kubectl get service -A | grep exporter
kube-system node-exporter NodePort 10.96.73.86 <none> 9100:31672/TCP 2m59s
2.2 Prometheus
[root@k8s-master prometheus]# pwd
/opt/k8s-prometheus-grafana-master/prometheus
[root@k8s-master prometheus]# ls
configmap.yaml prometheus.deploy.yml prometheus.svc.yml rbac-setup.yaml按照順序?rbac-setup.yaml?configmap.yaml?prometheus.deploy.yml?prometheus.svc.yml ，yaml、yml文件沒區(qū)別，不用在意。
[root@k8s-master prometheus]# kubectl apply -f rbac-setup.yaml
clusterrole.rbac.authorization.k8s.io/prometheus created
serviceaccount/prometheus created
clusterrolebinding.rbac.authorization.k8s.io/prometheus created
[root@k8s-master prometheus]# kubectl apply -f configmap.yaml
configmap/prometheus-config created
[root@k8s-master prometheus]# kubectl apply -f prometheus.deploy.yml
deployment.apps/prometheus created
[root@k8s-master prometheus]# kubectl apply -f prometheus.svc.yml
service/prometheus created2.3 grafana
[root@k8s-master grafana]# pwd
/opt/k8s-prometheus-grafana-master/grafana
[root@k8s-master grafana]# ls
grafana-deploy.yaml grafana-ing.yaml grafana-svc.yaml按照順序安裝?grafana-deploy.yaml?grafana-svc.yaml?grafana-ing.yaml
[root@k8s-master grafana]# kubectl apply -f grafana-deploy.yaml
deployment.apps/grafana-core created
[root@k8s-master grafana]# kubectl apply -f grafana-svc.yaml
service/grafana created
[root@k8s-master grafana]# kubectl apply -f grafana-ing.yaml
ingress.extensions/grafana created檢查三個(gè)pod（node-exporter可能有多個(gè)）
[root@k8s-master grafana]# kubectl get pod -A | grep node-exporter
kube-system node-exporter-kpdxh 1/1 Running 0 13m
[root@k8s-master grafana]# kubectl get pod -A | grep prometheus
kube-system prometheus-7486bf7f4b-xb4t8 1/1 Running 0 6m21s
[root@k8s-master grafana]# kubectl get pod -A | grep grafana
kube-system grafana-core-664b68875b-fhjvt 1/1 Running 0 2m18s
檢查服務(wù)service，三個(gè)svc類型均為NodePort
[root@k8s-master grafana]# kubectl get svc -A
NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
default kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 7h17m

kube-system prometheus NodePort 10.111.178.83 <none> 9090:30003/TCP 7m57s
2.4訪問(wèn)測(cè)試
curl訪問(wèn)測(cè)試?
[root@k8s-master grafana]# curl 127.0.0.1:31672
<html lang="en">
......
#node-exporter收集到的數(shù)據(jù)
[root@k8s-master grafana]# curl 127.0.0.1:31672/metrics

?訪問(wèn)11.0.1.12:31672/metrics，node-exporter收集到的數(shù)據(jù)
?訪問(wèn)11.0.1.12:30003/graph
選擇 "status"--"targets"
三、grafana初始化
訪問(wèn)11.0.1.12:31748/login
賬號(hào)密碼都是admin
3.1加載數(shù)據(jù)源
監(jiān)聽地址 10.111.178.83:9090，prometheus的service地址，重啟后grafana數(shù)據(jù)源地址可能會(huì)改變導(dǎo)致grafana連接不上prometheus且，注意檢測(cè)數(shù)據(jù)源地址。在左側(cè)configuration--data source可編輯數(shù)據(jù)源。
[root@k8s-master grafana]# kubectl get svc -A | grep prometheus
kube-system prometheus NodePort 10.111.178.83 <none> 9090:30003/TCP 40m
3.2導(dǎo)入模板
模板編號(hào)315
選擇數(shù)據(jù)源prometheus
?完成監(jiān)控
四、helm方式部署
