## Option 1: Docker Compose Deployment (Recommended)

### 1. Install Docker

```bash
# Ubuntu/Debian
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker $USER

# CentOS
sudo yum install -y docker docker-compose
sudo systemctl start docker
sudo systemctl enable docker
```

### 2. Prepare Configuration Files

```bash
# Clone code (or upload code to server)
git clone <your-repo-url> /opt/stock-analyzer
cd /opt/stock-analyzer

# Copy and edit configuration file
cp .env.example .env
vim .env  # Fill in real API Keys and configuration
```

### 3. One-Click Start

```bash
# Build and start
docker-compose -f ./docker/docker-compose.yml up -d

# View logs
docker-compose -f ./docker/docker-compose.yml logs -f

# View running status
docker-compose -f ./docker/docker-compose.yml ps
```

### 4. Common Management Commands

```bash
# Stop services
docker-compose -f ./docker/docker-compose.yml down

# Restart services
docker-compose -f ./docker/docker-compose.yml restart

# Redeploy after code update
git pull
docker-compose -f ./docker/docker-compose.yml build --no-cache
docker-compose -f ./docker/docker-compose.yml up -d

# Enter container for debugging
docker-compose -f ./docker/docker-compose.yml exec stock-analyzer bash

# Manually run analysis once
docker-compose -f ./docker/docker-compose.yml exec stock-analyzer python main.py --no-notify
```

### 5. Data Persistence

Data is automatically saved to host directories:
- `./data/` - Database files
- `./logs/` - Log files
- `./reports/` - Analysis reports

---

## Option 2: Direct Deployment

### 1. Install Python Environment

```bash
# Install Python 3.10+
sudo apt update
sudo apt install -y python3.10 python3.10-venv python3-pip

# Create virtual environment
python3.10 -m venv /opt/stock-analyzer/venv
source /opt/stock-analyzer/venv/bin/activate
```

### 2. Install Dependencies

```bash
cd /opt/stock-analyzer
pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple
```

### 3. Configure Environment Variables

```bash
cp .env.example .env
vim .env  # Fill in configuration
```

### 4. Run

```bash
# Single run
python main.py

# Scheduled task mode (foreground)
python main.py --schedule

# Background run (using nohup)
nohup python main.py --schedule > /dev/null 2>&1 &
```

---

## Option 3: Systemd Service

Create systemd service file for auto-start on boot and auto-restart:

### 1. Create Service File

```bash
sudo vim /etc/systemd/system/stock-analyzer.service
```

Contents:
```ini
[Unit]
Description=AI Stock Analysis System
After=network.target

[Service]
Type=simple
User=root
WorkingDirectory=/opt/stock-analyzer
Environment="PATH=/opt/stock-analyzer/venv/bin"
ExecStart=/opt/stock-analyzer/venv/bin/python main.py --schedule
Restart=always
RestartSec=30

[Install]
WantedBy=multi-user.target
```

### 2. Start Service

```bash
# Reload configuration
sudo systemctl daemon-reload

# Start service
sudo systemctl start stock-analyzer

# Enable auto-start on boot
sudo systemctl enable stock-analyzer

# View status
sudo systemctl status stock-analyzer

# View logs
journalctl -u stock-analyzer -f
```

---

## Proxy Configuration

If server is in mainland China, accessing Gemini API requires proxy:

### Docker Method

Edit `docker-compose.yml`:
```yaml
environment:
  - http_proxy=http://your-proxy:port
  - https_proxy=http://your-proxy:port
```

### Direct Deployment Method

Edit top of `main.py`:
```python
os.environ["http_proxy"] = "http://your-proxy:port"
os.environ["https_proxy"] = "http://your-proxy:port"
```

---

## Monitoring & Maintenance

### View Logs

```bash
# Docker method
docker-compose -f ./docker/docker-compose.yml logs -f --tail=100

# Direct deployment
tail -f /opt/stock-analyzer/logs/stock_analysis_*.log
```

### Health Check

```bash
# Check process
ps aux | grep main.py

# Check recent reports
ls -la /opt/stock-analyzer/reports/
```

### Routine Maintenance

```bash
# Clean old logs (keep 7 days)
find /opt/stock-analyzer/logs -mtime +7 -delete

# Clean old reports (keep 30 days)
find /opt/stock-analyzer/reports -mtime +30 -delete
```

---

## FAQ

### 1. Docker build failed

```bash
# Clear cache and rebuild
docker-compose -f ./docker/docker-compose.yml build --no-cache
```

### 2. API access timeout

Check proxy configuration, ensure server can access Gemini API.

### 3. Database locked

```bash
# Stop service then delete lock file
rm /opt/stock-analyzer/data/*.lock
```

### 4. Insufficient memory

Adjust memory limits in `docker-compose.yml`:
```yaml
deploy:
  resources:
    limits:
      memory: 1G
```

---

## Quick Migration

Migrate from one server to another:

```bash
# Source server: Package
cd /opt/stock-analyzer
tar -czvf stock-analyzer-backup.tar.gz .env data/ logs/ reports/

# Target server: Deploy
mkdir -p /opt/stock-analyzer
cd /opt/stock-analyzer
git clone <your-repo-url> .
tar -xzvf stock-analyzer-backup.tar.gz
docker-compose -f ./docker/docker-compose.yml up -d
```

## Option 4: GitHub Actions Deployment (Serverless)

**The simplest option!** No server needed, leverages GitHub's free compute resources.

### Advantages
- ✅ **Completely free** (2000 minutes/month)
- ✅ **No server needed**
- ✅ **Auto-scheduled execution**
- ✅ **Zero maintenance cost**

### Limitations
- ⚠️ Stateless (fresh environment each run)
- ⚠️ Scheduled timing may have few minutes delay
- ⚠️ Cannot provide HTTP API

### Deployment Steps

#### 1. Create GitHub Repository

```bash
# Initialize git (if not already)
cd /path/to/daily_stock_analysis
git init
git add .
git commit -m "Initial commit"

# Create GitHub repo and push
# After creating new repo on GitHub web:
git remote add origin https://github.com/your-username/daily_stock_analysis.git
git branch -M main
git push -u origin main
```

#### 2. Configure Secrets (Important!)

Go to repo page → **Settings** → **Secrets and variables** → **Actions** → **New repository secret**

Add these Secrets:

> *Note: Configure at least one notification channel, multiple channels supported for simultaneous push

#### 3. Verify Workflow File

Ensure `.github/workflows/daily_analysis.yml` file exists and is committed:

```bash
git add .github/workflows/daily_analysis.yml
git commit -m "Add GitHub Actions workflow"
git push
```

#### 4. Manual Test Run

1. Go to repo page → **Actions** tab
2. Select **"Daily Stock Analysis"** workflow
3. Click **"Run workflow"** button
4. Select run mode:
   - `full` - Full analysis (stocks + market)
   - `market-only` - Market review only
   - `stocks-only` - Stock analysis only
5. Click green **"Run workflow"** button

#### 5. View Execution Logs

- Actions page shows run history
- Click specific run record to view detailed logs
- Analysis reports are saved as Artifacts for 30 days

### Schedule Details

Default configuration: **Monday to Friday, 18:00 Beijing Time** auto-execution

Modify time: Edit cron expression in `.github/workflows/daily_analysis.yml`:

```yaml
schedule:
  - cron: '0 10 * * 1-5'  # UTC time, +8 = Beijing time
```

Common cron examples:
| Expression | Description |
|--------|------|
| `'0 10 * * 1-5'` | Mon-Fri 18:00 (Beijing) |
| `'30 7 * * 1-5'` | Mon-Fri 15:30 (Beijing) |
| `'0 10 * * *'` | Daily 18:00 (Beijing) |
| `'0 2 * * 1-5'` | Mon-Fri 10:00 (Beijing) |

### Modify Watchlist

Method 1: Modify repo Secret `STOCK_LIST`

Method 2: Modify code directly then push:
```bash
# Modify .env.example or set default value in code
git commit -am "Update stock list"
git push
```

### FAQ

**Q: Why isn't the scheduled task running?**
A: GitHub Actions scheduled tasks may have 5-15 minute delays, and only trigger when repo has activity. Long periods without commits may cause workflow to be disabled.

**Q: How to view historical reports?**
A: Actions → Select run record → Artifacts → Download `analysis-reports-xxx`

**Q: Is the free quota enough?**
A: Each run takes about 2-5 minutes, 22 workdays per month = 44-110 minutes, well below the 2000 minute limit.
