2. 下载 prometheus 包

# 拉包
$ helm pull prometheus-community/prometheus

$ ll
total 88
drwxr-xr-x 2 root   root    4096 Jul 16 03:12 ./
drwxrwxr-x 9 ubuntu ubuntu  4096 Jul 16 03:10 ../
-rw-r--r-- 1 root   root   80137 Jul 16 03:12 prometheus-27.16.0.tgz

# 解包
$ tar -zxvf prometheus-27.16.0.tgz 

###修改存储，需修改2处
vim values.yaml

## Prometheus server data Persistent Volume Storage Class
    ## If defined, storageClassName: <storageClass>
    ## If set to "-", storageClassName: "", which disables dynamic provisioning
    ## If undefined (the default) or set to null, no storageClassName spec is
    ##   set, choosing the default provisioner.  (gp2 on AWS, standard on
    ##   GKE, AWS & OpenStack)
    ##
    storageClass: "managed-nfs-storage"  ###修改为自己的动态存储名称

    ## Subdirectory of Prometheus server data Persistent Volume to mount
    ## Useful if the volume's root directory is not empty
    ##
    subPath: ""


vim charts/alertmanager/values.yaml 

persistence:
  enabled: true
  ## Persistent Volume Storage Class

2. 安装 grafana

$  helm install grafana grafana/grafana -n grafana --create-namespace
NAME: grafana
LAST DEPLOYED: Tue Jun  3 13:51:47 2025
NAMESPACE: grafana
STATUS: deployed
REVISION: 1
NOTES:
1. Get your 'admin' user password by running:

   kubectl get secret --namespace grafana grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo


2. The Grafana server can be accessed via port 80 on the following DNS name from within your cluster:

   grafana.grafana.svc.cluster.local

   Get the Grafana URL to visit by running these commands in the same shell:
     export POD_NAME=$(kubectl get pods --namespace grafana -l "app.kubernetes.io/name=grafana,app.kubernetes.io/instance=grafana" -o jsonpath="{.items[0].metadata.name}")
     kubectl --namespace grafana port-forward $POD_NAME 3000

3. Login with the password from step 1 and the username: admin
