|
||||
|
||||
## 1. 功能
|
||||
|
||||
### OLED
|
||||
|
||||
配套 OLED 按卖家原生参数锁定为：
|
||||
|
||||
- SSD1306
|
||||

|
||||
## v3.5.0 System Health
|
||||
|
||||
主页左右两栏都是固定位置、左对齐。数据默认每秒刷新。
|
||||
### 1. 供电与降频健康
|
||||
|
||||
有告警时，OLED 会在 HOME 与所有当前告警之间轮播；默认每页停留10秒。
|
||||
|
||||
### 风扇
|
||||
|
||||
默认：
|
||||
|
||||
```text
|
||||
< 50°C OFF
|
||||
50~53°C L1
|
||||
53~56°C L2
|
||||
56~59°C L3
|
||||
59~62°C L4
|
||||
>= 62°C MAX
|
||||
```
|
||||
|
||||
带降档回差，避免临界温度反复升降档。
|
||||
|
||||
### RGB 告警
|
||||
|
||||
正常状态 RGB 完全熄灭。
|
||||
|
||||
颜色表示“什么对象出问题”：
|
||||
|
||||
```text
|
||||
CPU 黄
|
||||
温度 红
|
||||
内存 紫
|
||||
磁盘 橙
|
||||
网络 蓝
|
||||
服务/进程 青
|
||||
```
|
||||
|
||||
所有告警都使用闪烁；闪烁速度表示严重程度：
|
||||
|
||||
```text
|
||||
Warning 慢
|
||||
Critical 中
|
||||
Emergency 快
|
||||
```
|
||||
|
||||
亮度可配置，默认10%，适合暗环境。
|
||||
|
||||
### Dark Mode
|
||||
|
||||
默认关闭 Raspberry Pi 自身：
|
||||
|
||||
- PWR LED
|
||||
- ACT LED
|
||||
|
||||
散热板 D1/D8 黄色硬件状态灯和独立电源模块绿色灯不属于已确认的软件控制接口，本程序不操作。
|
||||
|
||||
---
|
||||
|
||||
## 2. 全新 Raspberry Pi OS 安装
|
||||
|
||||
### 第一步：启用 I²C
|
||||
周期读取：
|
||||
|
||||
```bash
|
||||
sudo raspi-config
|
||||
vcgencmd get_throttled
|
||||
```
|
||||
|
||||
进入：
|
||||
区分：
|
||||
|
||||
- 当前欠压：立即 `POWER LOW / UNDERVOLT` 告警
|
||||
- 当前 CPU throttled / frequency capped：立即告警
|
||||
- 本次启动历史上曾欠压/降频：只写一次历史事件日志，不持续 RGB 告警
|
||||
- 状态恢复：写 `RECOVERED` 类事件
|
||||
|
||||
注意：这里检测的是 **Pi 的供电质量**，不是 UPS 电池百分比。
|
||||
|
||||
### 2. 文件系统健康
|
||||
|
||||
检测根文件系统 `/` 是否被内核切成只读。如果出现只读状态，产生严重告警：
|
||||
|
||||
```text
|
||||
Interface Options
|
||||
→ I2C
|
||||
→ Enable
|
||||
FILESYSTEM RO
|
||||
ROOT READ ONLY
|
||||
CHECK STORAGE
|
||||
```
|
||||
|
||||
然后：
|
||||
### 3. 本机诊断信息
|
||||
|
||||
内部维护：
|
||||
|
||||
- uptime
|
||||
- load average
|
||||
- CPU 当前频率
|
||||
- 当前/历史 throttled flags
|
||||
- 当前主网络接口 / IP
|
||||
- 根文件系统只读状态
|
||||
- sensor / network / service / health 最近成功时间
|
||||
- 主循环异常计数
|
||||
- I²C相关异常计数基础字段
|
||||
|
||||
### 4. DisplayController、OLED 与 RGB
|
||||
|
||||
每个当前故障都是 DisplayController 中的一个 active request，包含稳定 ID、priority、severity、OLED 显示数据、首次发现时间、最后变化时间和元数据。监控只提交或清除 request，同一轮采样作为一个原子批次，全部更新后只仲裁一次。DisplayController 始终只选一个最高优先级 owner；同一 ID 更新原请求而不重复入队，恢复时删除请求，同优先级新 request 排队而不抢占，owner 恢复后按 priority、first_seen、ID 重新仲裁。OLED 在主页和全部当前告警页之间轮播，告警页右上角显示 `当前页/告警总数`，新 owner 会立即抢占一次 OLED。告警页显示时 RGB 同步表达该页对象；回到主页时 RGB 保持最高优先级 active owner，全部恢复后才 OFF。历史 power flags 只进入 diagnose 和一次性 Journal 记录。
|
||||
|
||||
### 5. RGB 正常状态与告警引擎
|
||||
|
||||
没有 active alert 时，RGB 默认全灭。`[led] normal_mode` 可改为自定义颜色常亮/闪烁，或 MCU 已确认的流水、呼吸、跑马、彩虹和炫彩效果。常亮与闪烁使用 0..255 的自定义 R/G/B；内置流水/呼吸使用 MCU 固定的红、绿、蓝、黄、紫、青、白七色和慢/中/快三档速度，跑马/彩虹/炫彩由 MCU 自行配色。内置效果只在模式切换时按 speed → color → effect 的实机校准顺序写一次寄存器，不循环刷 I²C。
|
||||
|
||||
任何 active alert 都会立即抢占正常效果。RGB 告警模式由当前 OLED 告警页决定；OLED 位于主页时则使用最高优先级 active owner。颜色表示故障对象：CPU负载、频率、throttling、温度与散热相关为红色，供电/欠压为橙色，内存为紫色，存储为白色，网络/Wi-Fi 为蓝色，服务/进程为青色。频率表示严重等级：默认 Warning 为1500ms亮/1500ms灭，Critical 为750ms亮/750ms灭，Emergency 为300ms亮/300ms灭。`[led]` 可分别配置六类对象的 R/G/B 值，以及三个严重等级的亮灯和灭灯时长，非法颜色值会限制到0..255，间隔最小为50ms。每次点亮使用 v3.2.0 已验证的完整 selector/R/G/B 写入顺序，只在亮/灭边沿写 MCU，不做高频软件 PWM。相邻页面 RGB mode 相同时不关闭、不重启节奏。动画不写循环日志，owner 变化记录 `DISPLAY_OWNER`，实际模式变化才记录 `RGB_MODE`。
|
||||
|
||||
### 6. 结构化事件日志
|
||||
|
||||
日志继续交给 systemd journal，不额外制造长期 `.log` 文件。
|
||||
|
||||
只在 **状态发生变化** 时记录关键事件，避免每秒刷屏。例如：
|
||||
|
||||
```text
|
||||
level=INFO event=START version=3.6.0
|
||||
level=INFO event=NET_SWITCH old_if=eth0 new_if=wlan0 ...
|
||||
level=WARN event=NETWORK_DOWN ...
|
||||
level=INFO event=NETWORK_RECOVERED ...
|
||||
level=WARN event=WATCH_DOWN name=AWESUN ...
|
||||
level=INFO event=WATCH_RECOVERED name=AWESUN ...
|
||||
level=WARN event=POWER_LOW raw=0x1
|
||||
level=INFO event=POWER_RECOVERED raw=0x0
|
||||
level=WARN event=ALERT_ACTIVE alert=TEMP_HIGH ...
|
||||
level=INFO event=ALERT_RECOVERED ...
|
||||
```
|
||||
|
||||
实时查看：
|
||||
|
||||
```bash
|
||||
sudo reboot
|
||||
journalctl -u pigway-pi-control -f
|
||||
```
|
||||
|
||||
### 第二步：解压本安装包
|
||||
|
||||
进入解压后的目录：
|
||||
只看本次启动：
|
||||
|
||||
```bash
|
||||
cd pigway-pi-control-v3.2.0
|
||||
journalctl -u pigway-pi-control -b --no-pager
|
||||
```
|
||||
|
||||
### 第三步：安装
|
||||
搜索某类事件：
|
||||
|
||||
```bash
|
||||
journalctl -u pigway-pi-control --no-pager | grep 'event=POWER'
|
||||
```
|
||||
|
||||
### 7. 诊断命令
|
||||
|
||||
```bash
|
||||
sudo /usr/local/sbin/pigway-pi-control --diagnose
|
||||
```
|
||||
|
||||
输出 Agent 版本、系统 uptime、配置路径、load、CPU 频率、根文件系统、全部当前/历史 power 位、主网络接口、完整 IP 和 Internet 状态，以及所有 service/process watch 状态。
|
||||
|
||||
诊断使用与运行时相同的配置和检查函数；仅以 I²C receive-byte 读取探测 MCU 0x0D / OLED 0x3C，失败显示 MISSING/ERROR，不初始化或写入风扇、RGB、OLED。独立诊断进程无法获取正在运行的服务的内存计数，故 loop_errors / i2c_errors 明确标记 UNAVAILABLE；服务退出的 STOP 事件包含该次运行计数。
|
||||
|
||||
RGB 保留卖家 MCU 0x0D 寄存器协议。实机校准确认静态自定义颜色配合低频亮灭最稳定；每次点亮完整写入 selector/R/G/B，寄存器间隔默认10ms。旧版 `brightness`、呼吸周期和颜色选项可以继续留在用户配置中，但频闪引擎会忽略它们。
|
||||
|
||||
### 8. 关机收尾
|
||||
|
||||
收到 systemd SIGTERM / 系统关机时：
|
||||
|
||||
1. 写 STOP 日志
|
||||
2. RGB OFF
|
||||
3. 风扇 OFF
|
||||
4. OLED 清屏并 Display OFF
|
||||
5. 关闭 I²C handle
|
||||
|
||||
Pi 红色 PWR 灯关机后恢复硬件默认亮起的行为不强行修改，可作为“系统已关机但 UPS 仍供电”的直观提示。
|
||||
|
||||
## v3.6.0 API 与 Web
|
||||
|
||||
安装后访问：
|
||||
|
||||
```text
|
||||
http://树莓派IP:6001/
|
||||
```
|
||||
|
||||
Web 与 JSON API 由独立的 `pigway-pi-control-api.service` 提供。API 服务不访问 I²C；硬件 Agent 每秒原子更新 `/run/pigway-pi-control/status.json`，API 只读取该快照。默认监听地址和端口可在 `[api]` 中修改：
|
||||
|
||||
```ini
|
||||
[api]
|
||||
bind = 0.0.0.0
|
||||
port = 6001
|
||||
log_limit = 200
|
||||
```
|
||||
|
||||
只读接口：
|
||||
|
||||
```text
|
||||
GET /api/v1/health
|
||||
GET /api/v1/status
|
||||
GET /api/v1/logs?limit=200
|
||||
GET /api/v1/config
|
||||
GET /api/v1/services
|
||||
```
|
||||
|
||||
配置写入接口：
|
||||
|
||||
```text
|
||||
PUT /api/v1/config
|
||||
Authorization: Bearer <token>
|
||||
Content-Type: application/json
|
||||
|
||||
{"updates":{"led":{"service_b":"96"},"api":{"port":"6001"}}}
|
||||
```
|
||||
|
||||
服务监控页面会列出本机 systemd 服务，并标识“已监控/未监控”。添加、编辑或删除监控使用 `PUT /api/v1/services`；启动或停止服务使用 `PUT /api/v1/services/control`，两者均要求 Bearer Token。SSH、向日葵、Tailscale 和 PIGWay 自身服务不能从 Web 停止，以免中断远程管理或控制进程。监控备注保存在配置文件的 `[service_notes]`，不会参与硬件 Agent 的监控判断。
|
||||
|
||||
读取 token：
|
||||
|
||||
```bash
|
||||
sudo cat /etc/pigway-pi-control-api.token
|
||||
```
|
||||
|
||||
配置更新仅允许 `[services]`、`[processes]`、`[alerts]`、`[fan]`、`[led]`、`[timing]`、`[dark_mode]`、`[display]` 和 `[api]`。每次写入先生成时间戳备份，再原地更新目标键并重启硬件 Agent；修改 `[api]` 时 API 服务也会自动重启。
|
||||
|
||||
## 用户配置
|
||||
|
||||
正式配置只有一个：
|
||||
|
||||
```text
|
||||
/etc/pigway-pi-control.conf
|
||||
```
|
||||
|
||||
编辑：
|
||||
|
||||
```bash
|
||||
sudo nano /etc/pigway-pi-control.conf
|
||||
sudo systemctl restart pigway-pi-control
|
||||
```
|
||||
|
||||
配置文件内已经写明每项用途、单位和修改方式。
|
||||
|
||||
## 安装 / 升级测试分支

安装器会：
|
||||
|
||||
1. 检查 `/dev/i2c-1`
|
||||
2. 等待 APT/DPKG 锁
|
||||
3. 安装必要的小型系统依赖
|
||||
4. 检查 I²C 总线
|
||||
5. 自动停止并禁用卖家旧 `temp-control.service`
|

7. 安装用户配置
|
||||
8. 安装 systemd 服务并开机自启
|
||||
9. 执行安装后自检
|
||||
- 安装必要依赖
|
||||
- 检查 I²C，并在安装前检测 `/dev/i2c-1` 是否被其他 OLED/LED 控制进程占用
|
||||
- 发现冲突时列出进程并退出，由用户决定如何处理；安装器不会停止、禁用或杀死其他服务
|
||||
- 确认需要多个进程共用 I²C 时，可用 `sudo ./install.sh --force-i2c-conflict` 强制继续；冲突进程仍由用户自行管理
|
||||
- 安装字体、程序、配置和 systemd unit
|
||||
- 完整保留用户现有配置（包括所有 section、用户值和注释），仅补入缺失的 `[led]` 和 `[api]` 选项，已有用户值优先
|
||||
- 生成只读 root token，安装 API/Web 文件
|
||||
- 启动硬件 Agent 与 API/Web 服务
|
||||
- 执行版本、OLED、UI、P0健康监控和诊断入口自检

安装成功后查看：
|
||||
## 常用命令
|
||||
|
||||
```bash
|
||||
systemctl status pigway-pi-control --no-pager -l
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 3. 安装后的文件在哪里
|
||||
|
||||
### 用户应该修改
|
||||
|
||||
只有：
|
||||
|
||||
```text
|
||||
/etc/pigway-pi-control.conf
|
||||
```
|
||||
|
||||
编辑：
|
||||
|
||||
```bash
|
||||
sudo nano /etc/pigway-pi-control.conf
|
||||
```
|
||||
|
||||
保存后：
|
||||
|
||||
```bash
|
||||
sudo systemctl restart pigway-pi-control
|
||||
```
|
||||
|
||||
### 用户通常不要修改
|
||||
|
||||
程序：
|
||||
|
||||
```text
|
||||
/usr/local/sbin/pigway-pi-control
|
||||
```
|
||||
|
||||
systemd：
|
||||
|
||||
```text
|
||||
/etc/systemd/system/pigway-pi-control.service
|
||||
```
|
||||
|
||||
这些由安装包维护。
|
||||
|
||||
因此安装成功后，解压出来的 `pigway-pi-control-v3.2.0/` 文件夹可以删除。
|
||||
|
||||
建议把 ZIP 保存到 Mac / NAS，供以后重装。
|
||||
|
||||
---
|
||||
|
||||
## 4. 用户可以自定义什么
|
||||
|
||||
全部集中在：
|
||||
|
||||
```text
|
||||
/etc/pigway-pi-control.conf
|
||||
```
|
||||
|
||||
其中包括：
|
||||
|
||||
- 数据采样周期
|
||||
- OLED刷新周期
|
||||
- 告警页面停留时间
|
||||
- 网络检查周期
|
||||
- 服务检查周期
|
||||
- 风扇温度曲线
|
||||
- 风扇降档回差
|
||||
- CPU告警阈值和持续时间
|
||||
- 内存告警阈值和持续时间
|
||||
- 温度普通/严重告警
|
||||
- 磁盘普通/严重告警
|
||||
- RGB亮度
|
||||
- Warning/Critical/Emergency 闪烁周期
|
||||
- Pi PWR/ACT灯
|
||||
- 要监控的systemd服务
|
||||
- 要监控的普通进程
|
||||
|
||||
**每个参数在配置文件中都已经写有详细中文注释。**
|
||||
|
||||
---
|
||||
|
||||
## 5. 增加一个服务监控
|
||||
|
||||
编辑：
|
||||
|
||||
```bash
|
||||
sudo nano /etc/pigway-pi-control.conf
|
||||
```
|
||||
|
||||
找到：
|
||||
|
||||
```ini
|
||||
[services]
|
||||
SSH = ssh.service
|
||||
AWESUN = runawesun.service
|
||||
```
|
||||
|
||||
例如安装了 Tailscale：
|
||||
|
||||
```ini
|
||||
TAILSCALE = tailscaled.service
|
||||
```
|
||||
|
||||
保存后：
|
||||
|
||||
```bash
|
||||
sudo systemctl restart pigway-pi-control
|
||||
```
|
||||
|
||||
先确认服务真实名称：
|
||||
|
||||
```bash
|
||||
systemctl status tailscaled.service
|
||||
```
|
||||
|
||||
暂时不想监控，行首加 `#`：
|
||||
|
||||
```ini
|
||||
# TAILSCALE = tailscaled.service
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 6. 监控没有 systemd service 的程序
|
||||
|
||||
配置：
|
||||
|
||||
```ini
|
||||
[processes]
|
||||
MYAPP = /opt/myapp/server
|
||||
```
|
||||
|
||||
先测试：
|
||||
|
||||
```bash
|
||||
pgrep -af '/opt/myapp/server'
|
||||
```
|

## 7. 常用维护
|
||||
|
||||
状态：
|
||||
|
||||
```bash
|
||||
systemctl status pigway-pi-control --no-pager -l
|
||||
```
|
||||
|
||||
日志：
|
||||
|
||||
```bash
|
||||
journalctl -u pigway-pi-control-api -f
|
||||
journalctl -u pigway-pi-control -f
|
||||
```
|
||||
|
||||
重启：
|
||||
|
||||
```bash
|
||||
sudo systemctl restart pigway-pi-control
|
||||
sudo systemctl restart pigway-pi-control-api
|
||||
sudo /usr/local/sbin/pigway-pi-control --diagnose
|
||||
```
|
||||
|
||||
停止：
|
||||
## 版本路线
|
||||
|
||||
```bash
|
||||
sudo systemctl stop pigway-pi-control
|
||||
```
|
||||
|
||||
启动：
|
||||
|
||||
```bash
|
||||
sudo systemctl start pigway-pi-control
|
||||
```
|
||||
|
||||
查看配置：
|
||||
|
||||
```bash
|
||||
cat /etc/pigway-pi-control.conf
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 8. 升级
|
||||
|
||||
新版安装包直接：
|
||||
|
||||
```bash
|
||||
sudo ./install.sh
|
||||
```
|
||||
|
||||
安装器会保留用户已有的 `[services]` 和 `[processes]` 监控列表，并备份旧配置。
|
||||
|
||||
升级后检查：
|
||||
|
||||
```bash
|
||||
systemctl status pigway-pi-control --no-pager -l
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 9. 卸载
|
||||
|
||||
在安装包目录执行：
|
||||
|
||||
```bash
|
||||
sudo ./uninstall.sh
|
||||
```
|
||||
|
||||
卸载程序默认保留：
|
||||
|
||||
```text
|
||||
/etc/pigway-pi-control.conf
|
||||
```
|
||||
|
||||
避免误删用户自定义配置。
|
||||
|
||||
确认以后不再使用时可手工删除：
|
||||
|
||||
```bash
|
||||
sudo rm /etc/pigway-pi-control.conf
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 10. 重装树莓派时最短流程
|
||||
|
||||
以后即使完全忘记之前怎么安装，只需要：
|
||||
|
||||
```text
|
||||
1. 安装 Raspberry Pi OS
|
||||
2. raspi-config 开启 I²C
|
||||
3. 重启
|
||||
4. 解压本 ZIP
|
||||
5. cd pigway-pi-control-v3.2.0
|
||||
6. sudo ./install.sh
|
||||
```
|
||||
|
||||
完成。
|
||||
|
||||
## v3.2.0 网络状态增强
|
||||
|
||||
主页显示当前 Linux 默认路由接口：Wi-Fi 为 `WIF -52`（RSSI），有线为 `ETH 1G`（链路速率）。双网同时连接时跟随内核默认路由，IP 与该接口保持一致。新增 Wi-Fi 弱信号持续告警。
|
||||
- v3.2.0：主网络接口 / Wi-Fi RSSI / ETH速率 / 双网切换
|
||||
- v3.5.0：System Health、显示仲裁与可配置 RGB 告警
|
||||
- **v3.6.0：轻量状态/日志/配置 API 与同源 Web 管理界面**
