# Helm部署Nightingale
|
||
|
||
## 介绍
|
||
|
||
**Nightingale 是一个开源的监控工具，主要用于监控和分析电子病历系统（EMR）中的数据**。
|
||
|
||
## 开始部署
|
||
|
||
[官方文档](https://flashcat.cloud/docs/)
|
||
|
||
[项目仓库](https://github.com/ccfos/nightingale)
|
||
|
||
[Helm仓库地址](https://github.com/flashcatcloud/n9e-helm/tree/master)
|
||
|
||
1. 克隆 Helm 仓库
|
||
|
||
```bash
|
||
git clone https://github.com/flashcatcloud/n9e-helm.git
|
||
```
|
||
|
||
2. 编写 values.yaml
|
||
|
||
```bash
|
||
vi n9e-values.yaml
|
||
```
|
||
|
||
内容如下
|
||
|
||
```yaml
|
||
expose:
|
||
type: clusterIP # 使用 clusterIP
|
||
|
||
externalURL: https://填写域名 # 改为自己的外部服务访问地址
|
||
|
||
# 指定存储卷, 不指定则需要集群内存在默认的存储卷
|
||
persistence:
|
||
enabled: true
|
||
persistentVolumeClaim:
|
||
database:
|
||
storageClass: ""
|
||
redis:
|
||
storageClass: ""
|
||
prometheus:
|
||
storageClass: ""
|
||
|
||
categraf:
|
||
internal:
|
||
docker_socket: unix:///var/run/docker.sock # 如果您的kubernetes运行时是容器或其他，则清空此变量。
|
||
|
||
n9e:
|
||
internal:
|
||
image:
|
||
repository: flashcatcloud/nightingale
|
||
tag: latest # 使用最新版镜像
|
||
```
|
||
|
||
3. 部署
|
||
|
||
```bash
|
||
helm install nightingale ./n9e-helm -n monitor -f n9e-values.yaml --create-namespace
|
||
```
|
||
|
||
4. 创建 Nginx 证书 secret
|
||
|
||
> cert为.pem和.crt文件都可以
|
||
|
||
```bash
|
||
kubectl create secret tls n9e-tls --key nginx.key --cert nginx.pem -n monitor
|
||
```
|
||
|
||
5. 编写 ingress 文件
|
||
|
||
```bash
|
||
vi n9e-ingress.yaml
|
||
```
|
||
|
||
内容如下
|
||
|
||
```yaml
|
||
apiVersion: networking.k8s.io/v1
|
||
kind: Ingress
|
||
metadata:
|
||
name: n9e-ingress
|
||
namespace: monitor
|
||
spec:
|
||
ingressClassName: nginx
|
||
rules:
|
||
- host: # 域名
|
||
http:
|
||
paths:
|
||
- pathType: Prefix
|
||
backend:
|
||
service:
|
||
name: nightingale-center
|
||
port:
|
||
number: 80
|
||
path: /
|
||
tls:
|
||
- hosts:
|
||
- # 域名
|
||
secretName: n9e-tls
|
||
```
|
||
|
||
6. 部署 ingress
|
||
|
||
```bash
|
||
kubectl apply -f n9e-ingress.yaml
|
||
```
|
||
|
||
7. 访问验证
|
||
|
||
- 访问地址：https://hello.n9e.info
|
||
- 账户密码：root/root.2020
|
||
|
||
## 卸载
|
||
|
||
1. 删除 ingress
|
||
|
||
```bash
|
||
kubectl delete -f n9e-ingress.yaml
|
||
```
|
||
|
||
2. 卸载 nightingale
|
||
|
||
```bash
|
||
helm uninstall nightingale -n monitor
|
||
```
|
||
|
||
3. 删除 secret
|
||
|
||
```bash
|
||
kubectl delete secret n9e-tls -n monitor
|
||
```
|
||
|
||
4. 删除命名空间
|
||
|
||
```bash
|
||
kubectl delete namespace monitor
|
||
```
|
||
|
||
# 开始使用
|
||
|
||
添加自带的 prometheus 数据源
|
||
|
||
登录系统后点击 > 系统配置 > 数据源 > 添加
|
||
|
||
- 数据源名称
|
||
|
||
```bash
|
||
nightingale-prometheus
|
||
```
|
||
|
||
- URL
|
||
|
||
```bash
|
||
http://nightingale-prometheus:9090
|
||
```

# 如何配置外部数据库
|
||
|
||
## 使用外部数据库
|
||
|
||
> 仅为示例
|
||
|
||
更改 values.yaml 内 database 配置
|
||
|
||
```bash
|
||
vi n9e-values.yaml
|
||
```
|
||
|
||
内容如下
|
||
|
||
```yml
|
||
database:
|
||
type: external # 改为 external
|
||
external:
|
||
host: "192.168.1.10"
|
||
port: "3306"
|
||
name: "n9e_v6"
|
||
username: "root"
|
||
password: "root"
|
||
sslmode: "disable"
|
||
```
|
||
|
||
## 配置外部 Reids 启动
|
||
|
||
> 指定 Reids 运行模式为独立模式或哨兵模式
|
||
>
|
||
> 仅为示例
|
||
|
||
更改 values.yaml 内 redis 配置
|
||
|
||
```bash
|
||
vi n9e-values.yaml
|
||
```
|
||
|
||
内容如下
|
||
|
||
```yml
|
||
redis:
|
||
type: external
|
||
external:
|
||
addr: "192.168.1.10:6379"
|
||
sentinelMasterSet: ""
|
||
password: ""
|
||
mode: "standalone" # standalone/sentinel
|
||
```
|
||
|
||
# 问题记录
|
||
|
||
- 部署后 prometheus 无法抓取 n9e 监控目标
|
||
|
||
原因是因为：
|
||
|
||
1. prometheus 配置 svc 地址错误
|
||
2. helm 模版格式错误
|
||
|
||
解决方法：
