# 机器人 B 端开机自启说明
|
||||
# Robot B-Side Boot Chain
|
||||
|
||||
这个目录是给机器人端做开机自启用的。
|
||||
This directory contains the robot-side boot and recovery scripts.
|
||||
|
||||
你看到这里多了不少脚本和 `systemd` 单元,不是为了让你手工一条条执行,而是为了把开机流程拆开管理:
|
||||
|
||||
1. 固定启动顺序
|
||||
2. 某一步失败时可单独重试
|
||||
3. 所有动作统一写到一个本地日志文件
|
||||
4. 后面如果要把“固定延时 30 秒”换成“等待机器人原有自检完成”,只改最前面的闸门即可
|
||||
|
||||
所以平时真正需要人工执行的,通常只有这两步:
|
||||
Normal usage is:
|
||||
|
||||
```bash
|
||||
sudo bash scripts/boot/install-systemd.sh
|
||||
sudo systemctl start blitz-robot.target
|
||||
```
|
||||
|
||||
以后机器人重启时,就不需要你再手工执行这些脚本了。
|
||||
After installation, `blitz-robot.target` is enabled and will start automatically on reboot.
|
||||
|
||||
## 启动顺序
|
||||
To stop the chain now and disable boot-time autostart for future reboots:
|
||||
|
||||
当前开机链路如下:
|
||||
```bash
|
||||
sudo bash scripts/boot/disable-systemd.sh
|
||||
```
|
||||
|
||||
## Current Startup Order
|
||||
|
||||
The current cold-start chain is:
|
||||
|
||||
1. `blitz-boot-gate.service`
|
||||
2. `blitz-5g-dial.service`
|
||||
3. `blitz-time-sync.service`
|
||||
4. `blitz-ros-receiver.service`
|
||||
5. `blitz-b-side-omnid.service`
|
||||
3. `blitz-ros-receiver.service`
|
||||
4. `blitz-b-side-omnid.service`
|
||||
5. `blitz-watchdog.service`
|
||||
|
||||
对应业务顺序就是:
|
||||
There is no longer any automatic time-sync step in the boot chain.
|
||||
|
||||
1. 先固定等待 30 秒,给机器人原有自检/自启程序让路
|
||||
2. 运行 5G 自动拨号
|
||||
3. 运行时钟同步
|
||||
4. 启动 `start-ros-receiver.sh`
|
||||
5. 启动 `start-b-side-omnid.sh`
|
||||
## What Each Script Does
|
||||
|
||||
## 日志文件
|
||||
- `robot-boot.env`: default boot configuration
|
||||
- `robot-boot.env.local`: machine-local overrides
|
||||
- `common.sh`: shared env loading, logging, and helper functions
|
||||
- `boot-gate.sh`: fixed startup delay gate
|
||||
- `5g-dial.sh`: brings up the 5G modem path and verifies routing
|
||||
- `start-ros-receiver-service.sh`: boot wrapper for ROS receiver
|
||||
- `wait-for-unix-socket.sh`: waits for the ROS receiver unix socket
|
||||
- `start-b-side-omnid-service.sh`: boot wrapper for `b_side_omnid`
|
||||
- `blitz-watchdog.sh`: runtime health watchdog and recovery orchestrator
|
||||
- `blitz-fault-inject.sh`: fault injection entrypoint
|
||||
- `install-systemd.sh`: installs systemd units into `/etc/systemd/system`
|
||||
- `disable-systemd.sh`: stops the boot chain and disables autostart
|
||||
|
||||
所有关键操作都会统一写到这个本地文件:
|
||||
## Important Configuration
|
||||
|
||||
```text
|
||||
/var/log/blitz-robot/startup.log
|
||||
```
|
||||
|
||||
每一行日志格式如下:
|
||||
|
||||
```text
|
||||
timestamp | step | action | result | details | exit_code
|
||||
```
|
||||
|
||||
日志里会记录:
|
||||
|
||||
- 做了什么
|
||||
- 实际执行了什么命令
|
||||
- 前置检查是否通过
|
||||
- 成功还是失败
|
||||
- 失败原因
|
||||
- 退出码
|
||||
- 是否发生了重试
|
||||
|
||||
## 这些文件分别是干什么的
|
||||
|
||||
- `robot-boot.env`:开机自启默认配置
|
||||
- `robot-boot.env.local`:本机覆盖配置,建议把你自己的配置写这里
|
||||
- `common.sh`:公共环境加载和统一日志函数
|
||||
- `boot-gate.sh`:启动闸门,当前逻辑是固定等待 30 秒
|
||||
- `5g-dial.sh`:等待 5G 串口出现,执行 `rndis_dial.py`,删除 5G 默认路由并补齐目标主机路由,然后检查路由是否真的起来
|
||||
- `time-sync.sh`:把 `chrony` 指向白名单服务器 IP 和端口,并执行一次同步
|
||||
- `start-ros-receiver-service.sh`:开机版 ROS receiver 启动包装
|
||||
- `wait-for-unix-socket.sh`:等待 ROS receiver 建好本地 unix socket
|
||||
- `start-b-side-omnid-service.sh`:开机版 `b_side_omnid` 启动包装
|
||||
- `install-systemd.sh`:把 `systemd` 单元安装到 `/etc/systemd/system`
|
||||
- `systemd/*.service.in`、`systemd/*.target.in`:`systemd` 模板文件
|
||||
|
||||
## 前置条件
|
||||
|
||||
你前面说过,除了时钟同步以外,其他程序环境都应该已经配好了。按这个前提,这里只强调必须确认的前置条件。
|
||||
|
||||
### 1. 机器人侧必须已有的条件
|
||||
|
||||
默认认为下面这些已经具备:
|
||||
|
||||
- 系统是 Ubuntu,且使用 `systemd`
|
||||
- `OmniSocketGo` 仓库已经放在机器人上
|
||||
- `scripts/dev/start-ros-receiver.sh` 原本就能正常启动
|
||||
- `scripts/dev/start-b-side-omnid.sh` 原本就能正常启动
|
||||
- `bin/b_side_omnid` 已经提前编译好
|
||||
- 5G 拨号脚本存在:`/home/nvidia/5g-test/5G/rndis_dial.py`
|
||||
- 5G 串口设备是:`/dev/ttyUSB7`
|
||||
|
||||
注意:
|
||||
|
||||
- 开机模式下不会自动编译 `b_side_omnid`
|
||||
- 如果 `bin/b_side_omnid` 不存在,服务会直接报错并写日志
|
||||
|
||||
### 2. 时钟同步需要的前置安装
|
||||
|
||||
时钟同步这一步依赖 `chrony`。
|
||||
|
||||
如果机器人侧没有安装,请先安装:
|
||||
|
||||
```bash
|
||||
sudo apt update
|
||||
sudo apt install -y chrony
|
||||
```
|
||||
|
||||
安装后建议确认:
|
||||
|
||||
```bash
|
||||
systemctl status chrony
|
||||
chronyc tracking
|
||||
```
|
||||
|
||||
### 3. 云服务器侧需要的前置条件
|
||||
|
||||
因为你的 5G 是白名单网络,所以时钟同步不能依赖公网域名或默认 NTP 池,必须只用你的白名单云服务器 IP。
|
||||
|
||||
云服务器侧需要满足:
|
||||
|
||||
- 服务器上运行 `chronyd`
|
||||
- 安全组 / 防火墙放通你实际使用的 UDP 端口
|
||||
- 机器人能访问这台服务器的 IP
|
||||
|
||||
如果云服务器还没有安装 `chrony`,可以参考:
|
||||
|
||||
```bash
|
||||
sudo apt update
|
||||
sudo apt install -y chrony
|
||||
sudo systemctl enable chrony
|
||||
sudo systemctl restart chrony
|
||||
```
|
||||
|
||||
如果你不能使用标准的 `123/udp`,完全可以改成你自己的端口,例如 `10910/udp`。
|
||||
|
||||
例如云服务器 /etc/chrony/chrony.conf 里改成监听 10910::
|
||||
|
||||
```conf
|
||||
port 10910
|
||||
allow 0/0
|
||||
```
|
||||
|
||||
然后重启:
|
||||
|
||||
```bash
|
||||
sudo systemctl restart chrony
|
||||
```
|
||||
|
||||
机器人端则在 `robot-boot.env.local` 里配置:
|
||||
|
||||
```bash
|
||||
BLITZ_TIME_SERVER_IP="你的云服务器IP"
|
||||
BLITZ_TIME_SERVER_PORT="10910"
|
||||
```
|
||||
|
||||
这样 `time-sync.sh` 会自动生成:
|
||||
|
||||
```conf
|
||||
server 你的云服务器IP port 10910 iburst
|
||||
```
|
||||
|
||||
注意:这里必须是你自己可控的 `chronyd` 服务端。公网标准 NTP 服务通常只监听 `123/udp`,不能要求它们改到 `10910`。
|
||||
|
||||
## 需要改哪些配置
|
||||
|
||||
不要直接改 `robot-boot.env`,更推荐新建:
|
||||
Most machine-specific overrides should go into:
|
||||
|
||||
```text
|
||||
scripts/boot/robot-boot.env.local
|
||||
```
|
||||
|
||||
常见要改的是这些:
|
||||
Typical settings:
|
||||
|
||||
```bash
|
||||
BLITZ_BOOT_DELAY_SEC="30"
|
||||
BLITZ_LOG_FILE="/var/log/blitz-robot/startup.log"
|
||||
BLITZ_RUNTIME_DIR="/run/blitz-robot"
|
||||
|
||||
BLITZ_5G_DIAL_DIR="/home/nvidia/5g-test/5G"
|
||||
BLITZ_5G_SERIAL_PORT="/dev/ttyUSB7"
|
||||
BLITZ_5G_DIAL_DIR="${OMNISOCKETGO_ROOT}/scripts/boot"
|
||||
BLITZ_5G_SERIAL_PORT="/dev/ttyUSB2"
|
||||
BLITZ_5G_INTERFACE=""
|
||||
BLITZ_5G_MODEM_SUBNET="192.168.224.0/22"
|
||||
BLITZ_5G_GATEWAY="192.168.225.1"
|
||||
BLITZ_5G_REMOVE_DEFAULT_ROUTE="1"
|
||||
BLITZ_5G_ROUTE_TARGETS="106.55.173.235"
|
||||
BLITZ_5G_INFO_JSON="${OMNISOCKETGO_ROOT}/scripts/boot/modem_network_info.json"
|
||||
|
||||
BLITZ_TIME_SERVER_IP="你的白名单云服务器IP"
|
||||
BLITZ_TIME_SERVER_PORT="10910"
|
||||
BLITZ_TIME_SERVER_IP="81.70.156.140"
|
||||
|
||||
BLITZ_ROS_USER="nvidia"
|
||||
BLITZ_ROS_SOCKET_WAIT_SEC="20"
|
||||
BLITZ_WATCHDOG_INTERVAL_SEC="5"
|
||||
BLITZ_HEALTH_STALE_SEC="15"
|
||||
BLITZ_OMNID_THREAD_HEARTBEAT_TIMEOUT_SEC="15"
|
||||
BLITZ_NETWORK_FAIL_THRESHOLD="3"
|
||||
BLITZ_NETWORK_RECOVERY_COOLDOWN_SEC="30"
|
||||
BLITZ_WATCHDOG_ALLOW_FAULT_INJECTION="0"
|
||||
```
|
||||
|
||||
如果 `BLITZ_TIME_SERVER_IP` 留空,脚本会自动回退到 `ROBOT_SIDE_OMNISOCKET_SERVER_ADDR` 的 IP 部分。
|
||||
`BLITZ_TIME_SERVER_IP` is still used, but only as the 5G route/ping health-check target. It is no longer used for automatic clock synchronization.
|
||||
|
||||
当 `BLITZ_5G_REMOVE_DEFAULT_ROUTE="1"` 时,脚本会在 5G 拨号完成后删除该接口上的默认路由,避免整机默认出口切到 5G。此时 `BLITZ_TIME_SERVER_IP` 和 `BLITZ_5G_ROUTE_TARGETS` 中的目标 IP 会显式走 5G,其它流量继续走有线或 Wi-Fi 的默认路由。
|
||||
If `BLITZ_TIME_SERVER_IP` is left empty, the scripts fall back to the host part of `ROBOT_SIDE_OMNISOCKET_SERVER_ADDR`.
|
||||
|
||||
## 如何安装和使用
|
||||
## Install Or Upgrade
|
||||
|
||||
下面假设你当前目录就在 `OmniSocketGo` 仓库根目录。
|
||||
|
||||
### 第一步:准备本机配置
|
||||
|
||||
建议先创建:
|
||||
|
||||
```bash
|
||||
cp scripts/boot/robot-boot.env scripts/boot/robot-boot.env.local
|
||||
```
|
||||
|
||||
然后编辑:
|
||||
|
||||
```bash
|
||||
vim scripts/boot/robot-boot.env.local
|
||||
```
|
||||
|
||||
至少确认这几个值是对的:
|
||||
|
||||
- `BLITZ_5G_DIAL_DIR`
|
||||
- `BLITZ_5G_SERIAL_PORT`
|
||||
- `BLITZ_TIME_SERVER_IP`
|
||||
- `BLITZ_TIME_SERVER_PORT`
|
||||
- `BLITZ_ROS_USER`
|
||||
|
||||
### 第二步:安装 systemd 单元
|
||||
|
||||
执行:
|
||||
Run:
|
||||
|
||||
```bash
|
||||
sudo bash scripts/boot/install-systemd.sh
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl restart blitz-robot.target
|
||||
```
|
||||
|
||||
这个安装脚本会做这些事情:
|
||||
`install-systemd.sh` will also remove any old `blitz-time-sync.service` unit left over from earlier versions.
|
||||
|
||||
1. 创建日志目录和日志文件
|
||||
2. 渲染 `systemd` 模板
|
||||
3. 把 unit 文件复制到 `/etc/systemd/system`
|
||||
4. 执行 `systemctl daemon-reload`
|
||||
5. 执行 `systemctl enable blitz-robot.target`
|
||||
## Disable Autostart
|
||||
|
||||
### 第三步:立刻启动一次
|
||||
|
||||
执行:
|
||||
To stop the currently running services and disable autostart for future reboots:
|
||||
|
||||
```bash
|
||||
sudo bash scripts/boot/disable-systemd.sh
|
||||
```
|
||||
|
||||
To re-enable later:
|
||||
|
||||
```bash
|
||||
sudo bash scripts/boot/install-systemd.sh
|
||||
sudo systemctl start blitz-robot.target
|
||||
```
|
||||
|
||||
### 第四步:以后重启自动生效
|
||||
## Logs
|
||||
|
||||
因为安装脚本已经做了 `enable`,所以后续机器人重启时会自动拉起,不需要你再手工执行。
|
||||
|
||||
如果想手工确认,也可以执行:
|
||||
|
||||
```bash
|
||||
sudo systemctl enable blitz-robot.target
|
||||
```
|
||||
|
||||
## 如何查看是否正常
|
||||
|
||||
### 看总日志文件
|
||||
|
||||
最直接:
|
||||
|
||||
```bash
|
||||
tail -f /var/log/blitz-robot/startup.log
|
||||
```
|
||||
|
||||
### 看各个服务状态
|
||||
|
||||
```bash
|
||||
systemctl status blitz-robot.target
|
||||
systemctl status blitz-boot-gate.service
|
||||
systemctl status blitz-5g-dial.service
|
||||
systemctl status blitz-time-sync.service
|
||||
systemctl status blitz-ros-receiver.service
|
||||
systemctl status blitz-b-side-omnid.service
|
||||
```
|
||||
|
||||
### 看 journal
|
||||
|
||||
```bash
|
||||
journalctl -u blitz-robot.target -u blitz-boot-gate.service -u blitz-5g-dial.service \
|
||||
-u blitz-time-sync.service -u blitz-ros-receiver.service \
|
||||
-u blitz-b-side-omnid.service -f
|
||||
```
|
||||
|
||||
## 当前时钟同步会做什么
|
||||
|
||||
`time-sync.sh` 当前逻辑是:
|
||||
|
||||
1. 读取 `BLITZ_TIME_SERVER_IP`
|
||||
2. 读取 `BLITZ_TIME_SERVER_PORT`
|
||||
3. 修改 `/etc/chrony/chrony.conf`
|
||||
4. 注释掉原有的 `pool` 和 `server` 项
|
||||
5. 保留一个备份文件:`/etc/chrony/chrony.conf.blitz-bak`
|
||||
6. 写入:
|
||||
All boot-chain and watchdog logs are appended to:
|
||||
|
||||
```text
|
||||
/etc/chrony/sources.d/blitz-robot.sources
|
||||
/var/log/blitz-robot/startup.log
|
||||
```
|
||||
|
||||
7. 生成类似下面这一行:
|
||||
|
||||
```conf
|
||||
server 你的云服务器IP port 10910 iburst
|
||||
```
|
||||
|
||||
8. 重启 `chrony`
|
||||
9. 执行 `chronyc burst`
|
||||
10. 执行 `chronyc waitsync`
|
||||
|
||||
注意:
|
||||
|
||||
- 如果同步超时,会记日志为 `soft_fail`
|
||||
- 但不会阻塞后面的 ROS 和 `b_side_omnid` 启动
|
||||
|
||||
## 常见问题
|
||||
|
||||
### 1. 为什么会突然多出这么多脚本?
|
||||
|
||||
因为把开机流程拆成了多个稳定的小步骤:
|
||||
|
||||
- 更容易排查哪一步失败
|
||||
- 更容易让 `systemd` 自动重启
|
||||
- 更容易记录完整日志
|
||||
- 后续更容易替换“30 秒延时”为真正的机器人 ready 条件
|
||||
|
||||
你平时不需要手工逐个执行这些脚本。
|
||||
|
||||
### 2. 我是不是要手工跑 `5g-dial.sh`、`time-sync.sh`、`start-ros-receiver-service.sh`?
|
||||
|
||||
正常情况下不用。
|
||||
|
||||
你只需要:
|
||||
Follow the log live:
|
||||
|
||||
```bash
|
||||
sudo bash scripts/boot/install-systemd.sh
|
||||
sudo systemctl start blitz-robot.target
|
||||
sudo tail -f /var/log/blitz-robot/startup.log
|
||||
```
|
||||
|
||||
### 3. 如果时钟同步失败怎么办?
|
||||
|
||||
先看:
|
||||
Check service state:
|
||||
|
||||
```bash
|
||||
tail -f /var/log/blitz-robot/startup.log
|
||||
systemctl status blitz-time-sync.service
|
||||
chronyc sources -v
|
||||
chronyc tracking
|
||||
sudo systemctl status blitz-robot.target
|
||||
sudo systemctl status blitz-5g-dial.service
|
||||
sudo systemctl status blitz-ros-receiver.service
|
||||
sudo systemctl status blitz-b-side-omnid.service
|
||||
sudo systemctl status blitz-watchdog.service
|
||||
```
|
||||
|
||||
优先检查:
|
||||
|
||||
- `BLITZ_TIME_SERVER_IP` 是否填对
|
||||
- `BLITZ_TIME_SERVER_PORT` 是否填对
|
||||
- 云服务器是否真的跑了 `chronyd`
|
||||
- 云服务器防火墙 / 安全组是否放通你配置的 UDP 端口,例如 `10910`
|
||||
- 5G 白名单是否确实允许访问这个服务器 IP
|
||||
|
||||
### 4. 如果 ROS receiver 没起来怎么办?
|
||||
|
||||
先看:
|
||||
Check systemd journal:
|
||||
|
||||
```bash
|
||||
systemctl status blitz-ros-receiver.service
|
||||
tail -f /var/log/blitz-robot/startup.log
|
||||
sudo journalctl -u blitz-robot.target -u blitz-5g-dial.service \
|
||||
-u blitz-ros-receiver.service -u blitz-b-side-omnid.service \
|
||||
-u blitz-watchdog.service -f
|
||||
```
|
||||
|
||||
再检查:
|
||||
## Runtime Status Files
|
||||
|
||||
- `/opt/ros/${ROS_DISTRO}/setup.bash` 是否存在
|
||||
- `${ROS_CONTROL_PY_DIR}/install/setup.bash` 是否存在
|
||||
- `ROBOT_RECEIVER_LOCAL_SOCKET_PATH` 对应的 socket 是否出现
|
||||
The runtime status directory is:
|
||||
|
||||
### 5. 如果 b_side_omnid 没起来怎么办?
|
||||
```text
|
||||
/run/blitz-robot
|
||||
```
|
||||
|
||||
先看:
|
||||
Key files:
|
||||
|
||||
- `b-side-omnid.status.json`
|
||||
- `ros-receiver.status.json`
|
||||
- `watchdog.status.json`
|
||||
|
||||
Pretty-print them:
|
||||
|
||||
```bash
|
||||
systemctl status blitz-b-side-omnid.service
|
||||
tail -f /var/log/blitz-robot/startup.log
|
||||
sudo python3 -m json.tool /run/blitz-robot/watchdog.status.json
|
||||
sudo python3 -m json.tool /run/blitz-robot/b-side-omnid.status.json
|
||||
sudo python3 -m json.tool /run/blitz-robot/ros-receiver.status.json
|
||||
```
|
||||
|
||||
再检查:
|
||||
## Fault Injection
|
||||
|
||||
- `bin/b_side_omnid` 是否已经提前编译好
|
||||
- 摄像头设备是否存在
|
||||
- `robot-remote.env` / `robot-boot.env.local` 里的地址配置是否正确
|
||||
Available test commands:
|
||||
|
||||
```bash
|
||||
sudo bash scripts/boot/blitz-fault-inject.sh bside-crash
|
||||
sudo bash scripts/boot/blitz-fault-inject.sh bside-process-freeze
|
||||
sudo bash scripts/boot/blitz-fault-inject.sh bside-video-thread-stall
|
||||
sudo bash scripts/boot/blitz-fault-inject.sh bside-control-thread-stall
|
||||
sudo bash scripts/boot/blitz-fault-inject.sh ros-crash
|
||||
sudo bash scripts/boot/blitz-fault-inject.sh ros-freeze
|
||||
```
|
||||
|
||||
For synthetic network fault injection, first enable it in `robot-boot.env.local`:
|
||||
|
||||
```bash
|
||||
BLITZ_WATCHDOG_ALLOW_FAULT_INJECTION="1"
|
||||
```
|
||||
|
||||
Then restart watchdog and inject:
|
||||
|
||||
```bash
|
||||
sudo systemctl restart blitz-watchdog.service
|
||||
sudo bash scripts/boot/blitz-fault-inject.sh network-down on
|
||||
sudo bash scripts/boot/blitz-fault-inject.sh network-down off
|
||||
```
|
||||
|
||||
## Recovery Behavior Summary
|
||||
|
||||
- If `b_side_omnid` dies or its status file goes stale, watchdog first tries a targeted `b_side` restart.
|
||||
- If ROS receiver dies, loses its socket, or its heartbeat goes stale, watchdog performs an ordered full restart:
|
||||
- stop `b_side`
|
||||
- restart ROS receiver
|
||||
- wait for unix socket
|
||||
- start `b_side`
|
||||
- If network checks fail repeatedly, watchdog stops `b_side`, runs `5g-dial.sh`, waits for route recovery, and then restores services.
|
||||
- Camera disappearance is logged as degraded state. Reappearance triggers a `b_side` restart after the device is stable.
|
||||
|
||||
## Notes
|
||||
|
||||
- `time-sync.sh` and `blitz-time-sync.service` are intentionally removed from the automatic boot path.
|
||||
- `b_side_omnid` must already be built before boot-time startup.
|
||||
- `bin/b_side_omnid` missing, ROS env missing, or modem script missing will all show up in `startup.log`.
