└───────────────────────────────────────────────────────┘
二、服务器选型建议
| 项目 | 推荐配置 | 说明 |
|---|---|---|
| 机型 | 2C4G (标准型 SA2/S5) | Playwright 采集吃内存,2G 可能 OOM |
| 系统 | Ubuntu 22.04 LTS | Playwright 兼容性最好 |
| 磁盘 | 50GB SSD | SQLite + 视频 + 日志 |
| 带宽 | 5Mbps+ | 视频文件传输 |
| 安全组 | 开放 80/443 | SSH 用密钥登录,不开放 22 到公网 |
三、服务器初始化
3.1 SSH 连接
ssh ubuntu@<服务器公网IP>
3.2 安装系统依赖
sudo apt update && sudo apt upgrade -y
# 基础工具
sudo apt install -y build-essential git curl wget unzip
# Node.js 20.x
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo bash -
sudo apt install -y nodejs
# Python 3.11+
sudo apt install -y python3 python3-venv python3-pip python3-dev
# Nginx
sudo apt install -y nginx
# Playwright 系统依赖
sudo apt install -y libnss3 libatk1.0-0 libatk-bridge2.0-0 \
libcups2 libdrm2 libxkbcommon0 libxcomposite1 libxdamage1 \
libxrandr2 libgbm1 libpango-1.0-0 libcairo2 libasound2 \
libxshmfence1 libxfixes3
# Certbot (HTTPS)
sudo apt install -y certbot python3-certbot-nginx
3.3 创建部署目录
sudo mkdir -p /opt/cibank
sudo chown ubuntu:ubuntu /opt/cibank
四、代码部署
4.1 克隆代码
cd /opt/cibank
git clone https://git.all8ai.top/freedak/CIBank.git .
4.2 前端构建
cd /opt/cibank
npm install
npm run build
# 生成 dist/ 目录
4.3 后端配置
cd /opt/cibank/backend
# 创建虚拟环境
python3 -m venv venv
source venv/bin/activate
# 安装 Python 依赖
pip install -r requirements.txt
# 安装 Playwright Chromium
playwright install chromium
# 安装 gunicorn
pip install gunicorn
# 配置环境变量
cp .env.example .env
编辑 .env:
# 必填
DASHSCOPE_API_KEY=sk-xxxxxxxxxxxxxxxxxxxxxxxx
# 生产环境修改
FLASK_SECRET_KEY=$(openssl rand -hex 32)
PORT=8788
# 采集参数(按需调整)
CRAWL_ARTICLE_PAUSE=2.0
CRAWL_LIST_PAUSE=1.5
CRAWL_MAX_SCROLLS=15
CRAWL_LOOKBACK_DAYS=7
# ASR 配置(服务器端如不需要视频号转写可留空)
FFMPEG_PATH=/usr/bin/ffmpeg
FFPROBE_PATH=/usr/bin/ffprobe
# FUNASR_PATH 可以不配,视频号转写在本地完成
4.4 初始化数据库
cd /opt/cibank/backend
source venv/bin/activate
python3 -c "from app import ensure_schema; ensure_schema()"
4.5 迁移本地数据(可选)
如果本地已有数据,从 Mac 同步到服务器:
# 在本地 Mac 执行
scp backend/data/cibank.db ubuntu@<服务器IP>:/opt/cibank/backend/data/
scp -r backend/data/audio ubuntu@<服务器IP>:/opt/cibank/backend/data/
五、进程管理 (systemd)
5.1 后端 API 服务
创建 /etc/systemd/system/cibank-api.service:
sudo tee /etc/systemd/system/cibank-api.service > /dev/null << 'EOF'
[Unit]
Description=CIBank API Server (gunicorn)
After=network.target
[Service]
Type=exec
User=ubuntu
WorkingDirectory=/opt/cibank/backend
EnvironmentFile=/opt/cibank/backend/.env
ExecStart=/opt/cibank/backend/venv/bin/gunicorn \
-w 2 \
-b 127.0.0.1:8788 \
--timeout 300 \
--access-logfile /opt/cibank/backend/data/logs/gunicorn-access.log \
--error-logfile /opt/cibank/backend/data/logs/gunicorn-error.log \
app:app
Restart=always
RestartSec=5
[Install]
WantedBy=multi-user.target
EOF
5.2 每日流水线服务
创建 /etc/systemd/system/cibank-pipeline.service:
sudo tee /etc/systemd/system/cibank-pipeline.service > /dev/null << 'EOF'
[Unit]
Description=CIBank Daily Pipeline
After=network.target
[Service]
Type=oneshot
User=ubuntu
WorkingDirectory=/opt/cibank/backend
EnvironmentFile=/opt/cibank/backend/.env
ExecStart=/opt/cibank/backend/venv/bin/python3 /opt/cibank/backend/daily_pipeline.py daily
StandardOutput=append:/opt/cibank/backend/data/logs/pipeline.log
StandardError=append:/opt/cibank/backend/data/logs/pipeline-error.log
EOF
创建定时器 /etc/systemd/system/cibank-pipeline.timer:
sudo tee /etc/systemd/system/cibank-pipeline.timer > /dev/null << 'EOF'
[Unit]
Description=Run CIBank Daily Pipeline at 02:00
[Timer]
OnCalendar=*-*-* 02:00:00
Persistent=true
[Install]
WantedBy=timers.target
EOF
5.3 启动所有服务
# 创建日志目录
mkdir -p /opt/cibank/backend/data/logs
# 加载 systemd 配置
sudo systemctl daemon-reload
# 启动后端 API
sudo systemctl enable cibank-api
sudo systemctl start cibank-api
# 启动定时任务
sudo systemctl enable cibank-pipeline.timer
sudo systemctl start cibank-pipeline.timer
# 验证状态
sudo systemctl status cibank-api
sudo systemctl status cibank-pipeline.timer
六、Nginx 配置
6.1 创建站点配置
将 cibank.example.com 替换为你的实际域名:
sudo tee /etc/nginx/sites-available/cibank > /dev/null << 'EOF'
server {
listen 80;
server_name cibank.example.com;
# 前端静态文件
root /opt/cibank/dist;
index index.html;
# SPA 路由回退
location / {
try_files $uri $uri/ /index.html;
}
# API 反向代理
location /api/ {
proxy_pass http://127.0.0.1:8788;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_read_timeout 300s;
proxy_buffering off;
}
# 视频文件代理(大文件超时设长)
location /api/video/ {
proxy_pass http://127.0.0.1:8788;
proxy_set_header Host $host;
proxy_read_timeout 600s;
proxy_buffering on;
}
# 静态资源缓存
location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff2?)$ {
expires 30d;
add_header Cache-Control "public, immutable";
}
# 安全头
add_header X-Frame-Options "SAMEORIGIN";
add_header X-Content-Type-Options "nosniff";
}
EOF
6.2 启用站点
sudo ln -sf /etc/nginx/sites-available/cibank /etc/nginx/sites-enabled/
sudo rm -f /etc/nginx/sites-enabled/default
sudo nginx -t
sudo systemctl reload nginx
6.3 配置 HTTPS
# 申请 Let's Encrypt 证书(自动修改 Nginx 配置)
sudo certbot --nginx -d cibank.example.com
# 自动续期(certbot 默认已配置 systemd timer)
sudo systemctl status certbot.timer
七、视频号本地采集 + 同步方案
7.1 本地 Mac 采集流程(不变)
# 1. 启动 wx_channels_download
sudo networksetup -setv6off Wi-Fi
sudo <工具路径>/wx_video_download
# 2. 下载并自动转写
cd /Users/freedak/Documents/AIDashboard/CIBank/backend
python3 video_downloader.py
7.2 数据同步脚本
在本地 Mac 创建 sync_to_server.sh:
#!/bin/bash
# 将本地采集的视频号数据同步到服务器
# 用法: ./sync_to_server.sh
SERVER="ubuntu@cibank.example.com"
REMOTE_DIR="/opt/cibank/backend"
LOCAL_DIR="$(cd "$(dirname "$0")" && pwd)"
echo "=== 同步数据库到服务器 ==="
# 使用 rsync 增量同步数据库
rsync -avz --progress \
"$LOCAL_DIR/data/cibank.db" \
"$SERVER:$REMOTE_DIR/data/"
echo "=== 同步视频文件到服务器 ==="
rsync -avz --progress \
"$LOCAL_DIR/data/audio/" \
"$SERVER:$REMOTE_DIR/data/audio/"
echo "=== 同步完成 ==="
ssh "$SERVER" "systemctl restart cibank-api"
echo "后端服务已重启"
7.3 本地 3 天自动清理
在本地 Mac 创建 cleanup_local.sh:
#!/bin/bash
# 清理 3 天前的视频和音频文件
# 用法: ./cleanup_local.sh
AUDIO_DIR="$(cd "$(dirname "$0")" && pwd)/data/audio"
VIDEO_DIR="<你的视频下载目录>"
echo "=== 清理 3 天前的音频文件 ==="
find "$AUDIO_DIR" -type f -name "*.mp3" -mtime +3 -delete
find "$AUDIO_DIR" -type f -name "*.wav" -mtime +3 -delete
echo "=== 清理 3 天前的视频文件 ==="
find "$VIDEO_DIR" -type f \( -name "*.mp4" -o -name "*.flv" \) -mtime +3 -delete
echo "=== 清理完成 ==="
7.4 本地定时任务 (launchd)
创建 com.cibank.sync-and-cleanup.plist:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.cibank.sync-and-cleanup</string>
<key>ProgramArguments</key>
<array>
<string>/bin/bash</string>
<string>/Users/freedak/Documents/AIDashboard/CIBank/backend/sync_to_server.sh</string>
</array>
<key>StartCalendarInterval</key>
<dict>
<key>Hour</key>
<integer>3</integer>
<key>Minute</key>
<integer>0</integer>
</dict>
<key>StandardOutPath</key>
<string>/tmp/cibank-sync.log</string>
<key>StandardErrorPath</key>
<string>/tmp/cibank-sync-error.log</string>
</dict>
</plist>
安装定时任务:
cp com.cibank.sync-and-cleanup.plist ~/Library/LaunchAgents/
launchctl load ~/Library/LaunchAgents/com.cibank.sync-and-cleanup.plist
八、防火墙与安全
8.1 腾讯云安全组
| 端口 | 协议 | 来源 | 说明 |
|---|---|---|---|
| 443 | TCP | 0.0.0.0/0 | HTTPS |
| 80 | TCP | 0.0.0.0/0 | HTTP (certbot 验证 + 跳转) |
| 22 | TCP | 你的 IP only | SSH |
8.2 服务器防火墙
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow 22/tcp
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw enable
8.3 SSH 密钥登录
# 禁用密码登录
sudo sed -i 's/PasswordAuthentication yes/PasswordAuthentication no/' /etc/ssh/sshd_config
sudo systemctl restart sshd
九、日常运维
9.1 查看服务状态
# 后端 API
sudo systemctl status cibank-api
# 定时任务
sudo systemctl status cibank-pipeline.timer
sudo systemctl list-timers cibank-pipeline.timer
# Nginx
sudo systemctl status nginx
# 手动触发每日流水线
sudo systemctl start cibank-pipeline.service
9.2 查看日志
# API 日志
tail -f /opt/cibank/backend/data/logs/gunicorn-access.log
tail -f /opt/cibank/backend/data/logs/gunicorn-error.log
# 流水线日志
tail -f /opt/cibank/backend/data/logs/pipeline.log
# Nginx 日志
sudo tail -f /var/log/nginx/access.log
sudo tail -f /var/log/nginx/error.log
9.3 更新代码
cd /opt/cibank
git pull
# 前端重新构建
npm install && npm run build
# 后端依赖更新(如有变化)
cd backend
source venv/bin/activate
pip install -r requirements.txt
# 重启服务
sudo systemctl restart cibank-api
9.4 数据库备份
# 手动备份
sqlite3 /opt/cibank/backend/data/cibank.db ".backup /opt/cibank/backend/data/backups/cibank-$(date +%Y%m%d).db"
# 自动备份(cron)
crontab -e
# 添加:0 1 * * * sqlite3 /opt/cibank/backend/data/cibank.db ".backup /opt/cibank/backend/data/backups/cibank-$(date +\%Y\%m\%d).db"
