# Redis 部署说明
|
||||
|
||||
## 配置信息
|
||||
|
||||
- **命名空间**: redis
|
||||
- **存储**: 使用 Longhorn 提供 5Gi 持久化存储
|
||||
- **镜像**: redis:7-alpine
|
||||
- **持久化**: 启用 RDB + AOF 双重持久化
|
||||
- **内存限制**: 2GB
|
||||
- **访问地址**: redis.redis.svc.cluster.local:6379
|
||||
|
||||
## 部署方式
|
||||
|
||||
```bash
|
||||
bash deploy.sh
|
||||
```
|
||||
|
||||
## 持久化配置
|
||||
|
||||
### RDB 快照
|
||||
- 900秒内至少1个key变化
|
||||
- 300秒内至少10个key变化
|
||||
- 60秒内至少10000个key变化
|
||||
|
||||
### AOF 日志
|
||||
- 每秒同步一次
|
||||
- 自动重写阈值: 64MB
|
||||
|
||||
## 内存策略
|
||||
|
||||
- 最大内存: 2GB
|
||||
- 淘汰策略: allkeys-lru (所有key的LRU算法)
|
||||
|
||||
## 连接测试
|
||||
|
||||
在集群内部测试连接：
|
||||
|
||||
```bash
|
||||
kubectl run redis-test --rm -it --image=redis:7-alpine -- redis-cli -h redis.redis.svc.cluster.local ping
|
||||
```
|
||||
|
||||
## 备份说明
|
||||
|
||||
Redis 数据存储在 Longhorn 卷上，可以通过 Longhorn UI 创建快照和备份到 S3。
|
||||
|
||||
## 监控
|
||||
|
||||
可以通过以下命令查看 Redis 状态：
|
||||
|
||||
```bash
|
||||
kubectl exec -n redis $(kubectl get pod -n redis -l app=redis -o jsonpath='{.items[0].metadata.name}') -- redis-cli info
|
||||
```

|
||||
## 常用操作
|
||||
|
||||
### 查看日志
|
||||
```bash
|
||||
kubectl logs -n postgresql postgresql-0 -f
|
||||
```
|
||||
|
||||
### 进入数据库

||||
```bash
|
||||
kubectl exec -it -n postgresql postgresql-0 -- psql -U postgres
|
||||
```
|
||||
|
||||
### 创建新数据库
|
||||
```bash
|
||||
kubectl exec -n postgresql postgresql-0 -- psql -U postgres -c "CREATE DATABASE myapp;"
|
||||
```
|
||||
|
||||
### 创建新用户
|
||||
```bash
|
||||
kubectl exec -n postgresql postgresql-0 -- psql -U postgres -c "CREATE USER myuser WITH PASSWORD 'mypassword';"
|
||||
kubectl exec -n postgresql postgresql-0 -- psql -U postgres -c "GRANT ALL PRIVILEGES ON DATABASE myapp TO myuser;"
|
||||
```
|
||||
|
||||
## 备份与恢复
|
||||
|
||||
### 手动备份
|
||||
```bash

||||
kubectl exec -n postgresql postgresql-0 -- pg_dump -U postgres postgres > backup.sql
|
||||
```
|
||||
|
||||
### 恢复备份
|
||||
```bash
|
||||
cat backup.sql | kubectl exec -i -n postgresql postgresql-0 -- psql -U postgres postgres
|
||||
```
|
||||
|
||||
## 监控
|
||||
|
||||
查看数据库状态：
|
||||

|
||||
|
||||

|
||||
|
||||

|
||||
- 🎨 **美观界面**: 渐变背景、卡片式布局、悬停动画
|
||||
- 📱 **响应式设计**: 自适应各种屏幕尺寸
|
||||
- 🚀 **快速访问**: 一键跳转到所有服务
|
||||
|
||||

```
|
||||
|
||||
## 部署方式
|
||||
|
||||
```bash
|
||||
bash deploy.sh
|
||||
```
|
||||
|
||||
## 工作原理
|
||||
|
||||
1. **Generator 容器**:
|
||||
- 从 Caddy ConfigMap 挂载 Caddyfile
|
||||
- Python 脚本解析 Caddyfile，提取所有 `*.u6.net3w.com` 域名
|
||||
- 根据子域名前缀匹配图标和描述
|
||||
- 生成完整的 HTML 页面
|
||||
- 写入共享卷 `/usr/share/nginx/html/index.html`
|
||||
- 每 5 分钟重复一次
|
||||
|
||||
2. **Nginx 容器**:
|
||||
- 从共享卷读取 HTML 文件
|
||||
- 提供 HTTP 服务（端口 80）
|
||||
|
||||
3. **Ingress**:
|
||||
- 将 `dh.u6.net3w.com` 路由到 navigation 服务
|
||||
|
||||
## 服务图标映射

||||

| dh | 🏠 | 服务导航页面 |
|
||||
| test | 🧪 | 测试服务 |
|
||||
| 其他 | 🌐 | K3s 服务 |
|
||||
|
||||
## 添加新服务
|
||||
|
||||
当你在 Caddyfile 中添加新的域名配置时，导航页面会在 5 分钟内自动更新。
|
||||
|
||||
### 自定义图标和描述
|
||||
|
||||
编辑 ConfigMap 中的 `generator.py`，修改以下字典：
|
||||
|
||||
```python
|
||||
SERVICE_ICONS = {
|
||||
'newservice': '🎯', # 添加新服务的图标
|
||||
# ...
|
||||
}
|
||||
|
||||
SERVICE_DESCRIPTIONS = {
|
||||
'newservice': '新服务的描述', # 添加新服务的描述
|
||||
# ...
|
||||
}
|
||||
```
|
||||
|
||||
然后重新部署：
|
||||
|
||||
```bash
|
||||
kubectl apply -f deployment.yaml
|
||||
kubectl rollout restart deployment navigation -n navigation
|
||||
```
|
||||
|
||||
## 手动触发更新
|
||||
|
||||
如果需要立即更新导航页面：
|
||||
|
||||
```bash
|
||||
# 重启 generator 容器
|
||||
kubectl rollout restart deployment navigation -n navigation
|
||||
```
|
||||
|
||||
## 查看日志
|
||||
|
||||
```bash
|
||||
# 查看 generator 日志
|
||||
kubectl logs -n navigation -l app=navigation -c generator -f
|
||||
|
||||
# 查看 nginx 日志
|
||||
kubectl logs -n navigation -l app=navigation -c nginx -f
|
||||
```
|
||||
|
||||
## 自定义样式
|
||||
|
||||
如果需要修改页面样式，编辑 ConfigMap 中的 HTML 模板部分，然后重新部署。
|
||||
|
||||
## 故障排查
|
||||
|
||||
### 页面无法访问
|
||||
|
||||
```bash
|
||||
# 检查 Pod 状态
|
||||
kubectl get pods -n navigation
|
||||
|
||||
# 检查 Ingress
|
||||
kubectl get ingress -n navigation
|
||||
|
||||
# 检查服务
|
||||
kubectl get svc -n navigation
|
||||
```
|
||||
|
||||
### 页面未更新
|
||||
|
||||
```bash
|
||||
# 查看 generator 日志
|
||||
kubectl logs -n navigation -l app=navigation -c generator
|
||||
|
||||
# 检查 Caddy ConfigMap
|
||||
kubectl get configmap caddy-config -n default -o yaml
|
||||
|
||||
# 手动触发更新
|
||||
kubectl rollout restart deployment navigation -n navigation
|
||||
```
|
||||
|
||||
### Caddyfile 无法读取
|
||||
|
||||
确保 navigation 命名空间可以访问 default 命名空间的 ConfigMap：
|
||||
|
||||
```bash
|
||||
# 检查 ConfigMap 挂载
|
||||
kubectl describe pod -n navigation -l app=navigation
|
||||
```
|
||||
|
||||
## 性能优化
|
||||
|
||||
- **更新频率**: 默认 5 分钟，可在 `generator.py` 中修改 `time.sleep(300)`
|
||||
- **缓存**: Nginx 自动缓存静态文件
|
||||
- **资源限制**: 可根据需要添加资源限制
|
||||
|
||||
## 卸载
|
||||
|
||||
```bash
|
||||
kubectl delete namespace navigation
|
||||
```
|
||||
|
||||
## 未来改进
|
||||
|
||||
- [ ] 添加服务健康状态检查
|
||||
- [ ] 支持服务分组
|
||||
- [ ] 添加搜索功能
|
||||
- [ ] 支持深色模式
|
||||
- [ ] 添加访问统计
|
||||

|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
既然你的基础设施已经有了 **PG16、S3、Longhorn 和 Helm**，那么 Redis 的规划应该朝着“标准生产环境”看齐。
|
||||
|
||||
我们将 Redis 放在一个新的分类文件夹下，与基础设施解耦。
|
||||
|
||||
---
|
||||
|
||||
## 1. 目录结构规划
|
||||
|
||||
建议在你的 `k3s` 根目录下创建 `010-中间件`，专门存放这类有状态的服务：
|
||||
|
||||
```text
|
||||
/home/fei/k3s/
|
||||
├── 009-基础设施/
|
||||
│ ├── 002-s3/
|
||||
│ ├── 003-helm/
|
||||
│ └── 004-longhorn/
|
||||
└── 010-中间件/
|
||||
└── 001-redis/
|
||||
├── kustomization.yaml (或 deploy.sh)
|
||||
├── pvc.yaml (声明 Longhorn 存储)
|
||||
├── redis-conf.yaml (配置密码和持久化)
|
||||
└── deployment.yaml (或 statefulset.yaml)
|
||||
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 2. 核心部署方案：StatefulSet vs Deployment
|
||||
|
||||
对于 Redis 独立 Pod：
|
||||
|
||||
* **不要用 Deployment：** 它是为无状态设计的，Pod 名字随机，且多个副本会争抢同一个存储。
|
||||
* **推荐使用 StatefulSet：** 专门用于数据库。Pod 名字固定（如 `redis-0`），且能完美绑定 Longhorn 的磁盘。
|
||||
|
||||
---
|
||||
|
||||
## 3. 关键配置清单 (YAML 逻辑)
|
||||
|
||||
### A. 存储规划 (`pvc.yaml`)
|
||||
|
||||
利用 Longhorn 提供的动态供应，不需要手动创建 PV。
|
||||
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: PersistentVolumeClaim
|
||||
metadata:
|
||||
name: redis-data
|
||||
namespace: middleware
|
||||
spec:
|
||||
accessModes:
|
||||
- ReadWriteOnce
|
||||
storageClassName: longhorn # 指向你刚装好的 Longhorn
|
||||
resources:
|
||||
requests:
|
||||
storage: 5Gi # Redis 主要是内存存储，5G 足够放持久化文件了
|
||||
|
||||
```
|
||||
|
||||
### B. 配置规划 (`redis-conf.yaml`)
|
||||
|
||||
为了安全和持久化，通过 `ConfigMap` 管理配置：
|
||||
|
||||
* **密码：** 必须设置 `requirepass`。
|
||||
* **持久化：** 开启 `appendonly yes` (AOF)，每秒同步一次，保证数据在 Longhorn 上的安全。
|
||||
|
||||
---
|
||||
|
||||
## 4. 性能与资源限制 (Resources)
|
||||
|
||||
在 Kubernetes 中跑 Redis，最忌讳不设限制。如果 Redis 内存泄露，会撑爆整个 K3s 节点。
|
||||
|
||||
* **Memory Limit：** 必须设置。例如给 2GB 内存。
|
||||
* **maxmemory：** Redis 内部配置应略小于 Pod 限制（如 1.5GB），防止被系统 OOM Kill。
|
||||
|
||||
---
|
||||
|
||||
## 5. 进阶：如何监控？
|
||||
|
||||
既然你已经有了这些基础设施，建议 Redis 规划中预留 **Prometheus Exporter** 的位置。
|
||||
|
||||
* 在 Redis Pod 旁边加一个辅助容器（Sidecar），专门把 Redis 的运行状态（命中率、内存占用、连接数）转为监控指标。
|
||||
|
||||
---
|
||||
|
||||
## 6. 你的执行清单 (Action Plan)
|
||||
|
||||
1. **创建命名空间：** `kubectl create ns middleware`。
|
||||
2. **编写 values.yaml：** 虽然可以用原生 YAML，但我建议你继续用 Helm 模式。
|
||||
* 使用 Bitnami 的 Redis Chart：`helm repo add bitnami https://charts.bitnami.com/bitnami`。
|
||||
* 在你的 `001-redis` 文件夹下创建一个 `my-values.yaml`。
|
||||
|
||||
|
||||
3. **关联 Longhorn：** 在 `my-values.yaml` 中设置 `global.storageClass: longhorn`。
|
||||
4. **关联 S3 (可选)：** 如果你想把 Redis 的 RDB 定期传到 S3，可以写一个简单的 `CronJob`。
|
||||
|
||||
**你需要我为你提供一份完整的、可直接在 `001-redis` 文件夹下运行的 `helm install` 命令和对应的 `values.yaml` 配置吗？**
