## 一:环境准备
#### 1.kubernetes集群正常
```shell
[root@master ~]# kubectl get node
NAME STATUS ROLES AGE VERSION
master Ready control-plane,master 36d v1.23.1
node-1 Ready <none> 36d v1.23.1
node-2 Ready <none> 36d v1.23.1
node-3 Ready <none> 36d v1.23.1
```
#### 2.harbor仓库正常

## 二Prometheus部署
#### 1.node-exporter部署
node-exporter可以采集机器物理机、虚拟机、云主机等的监控指标数据能够采集到的指标包括CPU, 内存,磁盘,网络,文件数等信息
创建监控namespace
```shell
[root@master ~]# kubectl create ns monitor-sa
```
创建node-export.yaml
```shell
[root@master ~]# vim node-export.yaml
apiVersion: apps/v1
kind: DaemonSet # 可以保证k8s集群的每个节点都运行完全一样的pod
metadata:
name: node-exporter
namespace: monitor-sa
labels:
name: node-exporter
spec:
selector:
matchLabels:
name: node-exporter
template:
metadata:
labels:
name: node-exporter
spec:
hostPID: true
hostIPC: true
hostNetwork: true
containers:
- name: node-exporter
image: prom/node-exporter:v0.16.0
#image: 10.0.0.230/xingdian/node-exporter:v0.16.0
ports:
- containerPort: 9100
resources:
requests:
cpu: 0.15 # 这个容器运行至少需要0.15核cpu
securityContext:
privileged: true # 开启特权模式
args:
- --path.procfs
- /host/proc
- --path.sysfs
- /host/sys
- --collector.filesystem.ignored-mount-points
- '"^/(sys|proc|dev|host|etc)($|/)"'
volumeMounts:
- name: dev
mountPath: /host/dev
- name: proc
mountPath: /host/proc
- name: sys
mountPath: /host/sys
- name: rootfs
mountPath: /rootfs
tolerations:
- key: "node-role.kubernetes.io/master"
operator: "Exists"
effect: "NoSchedule"
volumes:
- name: proc
hostPath:
path: /proc
- name: dev
hostPath:
path: /dev
- name: sys
hostPath:
path: /sys
- name: rootfs
hostPath:
path: /
```
注意:
hostNetwork、hostIPC、hostPID都为True时表示这个Pod里的所有容器会直接使用宿主机的网络直接与宿主机进行IPC进程间通信通信可以看到宿主机里正在运行的所有进程。加入了hostNetwork:true会直接将我们的宿主机的9100端口映射出来从而不需要创建service 在我们的宿主机上就会有一个9100的端口
创建:
```shell
[root@master ~]# kubectl apply -f node-export.yaml
```
查看node-exporter是否部署成功
```shell
[root@master ~]# kubectl get pods -n monitor-sa -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
node-exporter-2cbrg 1/1 Running 0 34m 10.0.0.220 master <none> <none>
node-exporter-7rrbh 1/1 Running 0 34m 10.0.0.222 node-2 <none> <none>
node-exporter-96v29 1/1 Running 0 34m 10.0.0.221 node-1 <none> <none>
node-exporter-bf2j8 1/1 Running 0 34m 10.0.0.223 node-3 <none> <none>
```
注意:
node-export默认的监听端口是9100可以看到当前主机获取到的所有监控数据
```shell

#### 2.Prometheus安装
创建sa账号对sa做rbac授权
```shell
# 创建一个sa账号monitor
[root@master ~]# kubectl create serviceaccount monitor -n monitor-sa
# 把sa账号monitor通过clusterrolebing绑定到clusterrole上
[root@master ~]# kubectl create clusterrolebinding monitor-clusterrolebinding -n monitor-sa --clusterrole=cluster-admin --serviceaccount=monitor-sa:monitor
```
创建prometheus数据存储目录
```shell
# 将prometheus调度到node-1节点
[root@node-1 ~]# mkdir /data && chmod 777 /data
```
创建一个configmap存储卷用来存放prometheus配置信息
```shell
[root@master ~]# vim prometheus-cfg.yaml

创建:
```shell
[root@master ~]# kubectl apply -f prometheus-deploy.yaml

查看:
```shell
[root@master ~]# kubectl get pods -o wide -n monitor-sa

prometheus-server-59cb5d648-bxwrb 1/1 Running 0 14m 10.244.2.100 node-1 <none> <none>
```
#### 3.prometheus pod创建service
```shell
[root@master ~]# cat prometheus-svc.yaml
apiVersion: v1
kind: Service
metadata:
name: prometheus
namespace: monitor-sa
labels:
app: prometheus
spec:
type: NodePort
ports:

```
创建:
```shell
[root@master ~]# kubectl apply -f prometheus-svc.yaml
service/prometheus created
```
查看service在物理机映射的端口
```shell
[root@master ~]# kubectl get svc -n monitor-sa

#### 5.Prometheus热加载
```shell
# 为了每次修改配置文件可以热加载prometheus也就是不停止prometheus就可以使配置生效想要使配置生效可用如下热加载命令
[root@master ~]# kubectl get pods -n monitor-sa -o wide -l app=prometheus
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
prometheus-server-689fb8cdbc-kcsw2 1/1 Running 0 5m39s 10.244.36.70 k8s-node1 <none> <none>
# 想要使配置生效可用如下命令热加载:
[root@master ~]# curl -X POST http://10.244.36.70:9090/-/reload
# 查看log
[root@master ~]# kubectl logs -n monitor-sa prometheus-server-689fb8cdbc-kcsw2
```
注意:
```shell
# 热加载速度比较慢可以暴力重启prometheus如修改上面的prometheus-cfg.yaml文件之后可执行如下强制删除
[root@master ~]# kubectl delete -f prometheus-cfg.yaml
[root@master ~]# kubectl delete -f prometheus-deploy.yaml
# 然后再通过apply更新
[root@master ~]# kubectl apply -f prometheus-cfg.yaml
[root@master ~]# kubectl apply -f prometheus-deploy.yaml
#注意:线上最好热加载,暴力删除可能造成监控数据的丢失
```
## 三Grafana的部署
#### 1.Grafana介绍
Grafana是一个跨平台的开源的度量分析和可视化工具可以将采集的数据可视化的展示并及时通知给告警接收方
它主要有以下六大特点:
1展示方式快速灵活的客户端图表面板插件有许多不同方式的可视化指标和日志官方库中具有丰富的仪表盘插件比如热图、折线图、图表等多种展示方式
2数据源GraphiteInfluxDBOpenTSDBPrometheusElasticsearchCloudWatch和KairosDB等
3通知提醒以可视方式定义最重要指标的警报规则Grafana将不断计算并发送通知在数据达到阈值时通过Slack、PagerDuty等获得通知
4混合展示在同一图表中混合使用不同的数据源可以基于每个查询指定数据源甚至自定义数据源
5注释使用来自不同数据源的丰富事件注释图表将鼠标悬停在事件上会显示完整的事件元数据和标记
#### 2.Grafana安装
