1. 生产环境硬件配置

1.1 GPU硬件选型

FaceFusion重度依赖GPU进行AI推理，合理的GPU配置至关重要：

GPU型号	显存容量	推荐场景	并发处理能力
NVIDIA RTX 4090	24GB	中小规模生产	3-5路并发
NVIDIA A100	40/80GB	大规模生产	8-12路并发
NVIDIA H100	80GB	超大规模生产	15-20路并发

1.2 CPU与内存配置

1.3 执行提供者配置

FaceFusion支持多种执行提供者（Execution Providers），生产环境推荐配置：

[execution]
execution_providers = CUDA, TensorRT, CPU
execution_thread_count = 4
execution_queue_count = 8

2. 容器化部署方案

2.1 Docker镜像构建

创建生产级Dockerfile：

FROM nvidia/cuda:12.2.0-runtime-ubuntu22.04

# 设置基础环境
ENV DEBIAN_FRONTEND=noninteractive
RUN apt-get update && apt-get install -y \
    python3.10 \
    python3-pip \
    ffmpeg \
    libsm6 \
    libxext6 \
    && rm -rf /var/lib/apt/lists/*

# 安装Python依赖
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

# 复制应用代码
COPY . /app
WORKDIR /app

# 设置环境变量
ENV PYTHONPATH=/app
ENV NVIDIA_VISIBLE_DEVICES=all
ENV NVIDIA_DRIVER_CAPABILITIES=compute,utility

# 启动命令
CMD ["python", "facefusion.py", "run"]

2.2 Kubernetes部署配置

创建Kubernetes部署清单：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: facefusion
  namespace: production
spec:
  replicas: 3
  selector:
    matchLabels:
      app: facefusion
  template:
    metadata:
      labels:
        app: facefusion
    spec:
      containers:
      - name: facefusion
        image: registry.example.com/facefusion:1.0.0
        resources:
          limits:
            nvidia.com/gpu: 1
            memory: "16Gi"
            cpu: "4"
          requests:
            memory: "8Gi"
            cpu: "2"
        env:
        - name: EXECUTION_PROVIDERS
          value: "CUDA,TensorRT"
        - name: EXECUTION_THREAD_COUNT
          value: "4"
        ports:
        - containerPort: 7860
        volumeMounts:
        - name: models
          mountPath: /app/models
        - name: temp
          mountPath: /tmp
      volumes:
      - name: models
        persistentVolumeClaim:
          claimName: models-pvc
      - name: temp
        emptyDir: {}
      tolerations:
      - key: nvidia.com/gpu
        operator: Exists
        effect: NoSchedule
---
apiVersion: v1
kind: Service
metadata:
  name: facefusion-service
  namespace: production
spec:
  selector:
    app: facefusion
  ports:
  - port: 7860
    targetPort: 7860
  type: LoadBalancer

3. 性能优化策略

3.1 内存管理配置

[memory]
video_memory_strategy = strict
system_memory_limit = 8

[frame_extraction]
temp_frame_format = jpg
keep_temp = false

3.2 模型缓存优化

实现模型预加载和缓存机制：

# 模型预加载脚本
import facefusion.inference_manager as inference_manager

def preload_models():
    models_to_preload = [
        'face_detector',
        'face_landmarker', 
        'face_swapper',
        'face_enhancer'
    ]
    
    for model in models_to_preload:
        inference_manager.get_inference_pool(model, ['default'], {})
        print(f"Preloaded model: {model}")

if __name__ == "__main__":
    preload_models()

3.3 批处理优化

利用FaceFusion的批处理功能提升吞吐量：

# 批量处理命令
python facefusion.py batch-run \
  --source-path /data/source \
  --target-path /data/target \
  --output-path /data/output \
  --processors face_swapper,face_enhancer \
  --execution-thread-count 8

4. 监控与告警体系

4.1 监控指标采集

关键监控指标配置：

# Prometheus监控配置
- job_name: 'facefusion'
  static_configs:
  - targets: ['facefusion-service:7860']
  metrics_path: '/metrics'
  scrape_interval: 15s

# 关键性能指标
metrics:
  - name: gpu_utilization
    help: GPU utilization percentage
    type: gauge
    
  - name: inference_latency  
    help: Model inference latency in milliseconds
    type: histogram
    
  - name: processing_throughput
    help: Frames processed per second
    type: counter
    
  - name: memory_usage
    help: Memory usage in megabytes
    type: gauge

4.2 告警规则配置

groups:
- name: facefusion-alerts
  rules:
  - alert: HighGPUUsage
    expr: gpu_utilization > 90
    for: 5m
    labels:
      severity: warning
    annotations:
      summary: "High GPU utilization detected"
      
  - alert: HighInferenceLatency
    expr: histogram_quantile(0.95, inference_latency) > 1000
    for: 2m
    labels:
      severity: critical
    annotations:
      summary: "High inference latency detected"
      
  - alert: MemoryLeakDetected
    expr: increase(memory_usage[1h]) > 1024
    for: 30m
    labels:
      severity: warning

5. 高可用与灾备方案

5.1 多节点集群部署

mermaid

5.2 数据备份策略

#!/bin/bash
# 备份脚本
BACKUP_DIR="/backup/facefusion"
TIMESTAMP=$(date +%Y%m%d_%H%M%S)

# 备份配置文件
tar -czf $BACKUP_DIR/config_$TIMESTAMP.tar.gz /app/facefusion.ini

# 备份模型文件
rsync -av --delete /app/models/ $BACKUP_DIR/models/

# 备份日志文件
find /var/log/facefusion -name "*.log" -mtime -7 -exec tar -czf $BACKUP_DIR/logs_$TIMESTAMP.tar.gz {} +

# 清理旧备份
find $BACKUP_DIR -name "*.tar.gz" -mtime +30 -delete

6. 安全与合规

6.1 网络安全配置

# 网络策略配置
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: facefusion-network-policy
  namespace: production
spec:
  podSelector:
    matchLabels:
      app: facefusion
  policyTypes:
  - Ingress
  - Egress
  ingress:
  - from:
    - namespaceSelector:
        matchLabels:
          name: ingress-nginx
    ports:
    - protocol: TCP
      port: 7860
  egress:
  - to:
    - ipBlock:
        cidr: 10.0.0.0/8
    ports:
    - protocol: TCP
      port: 443
    - protocol: TCP
      port: 80

6.2 数据保护措施

[paths]
temp_path = /secure/temp
jobs_path = /secure/jobs

[patterns]
source_pattern = *.jpg,*.png,*.mp4
target_pattern = *.jpg,*.png,*.mp4
output_pattern = *.jpg,*.png,*.mp4

[misc]
log_level = INFO
halt_on_error = true

7. 运维自动化

7.1 自动化部署流水线

mermaid

7.2 自动化运维脚本

#!/usr/bin/env python3
# 自动化运维工具
import subprocess
import json
import requests
from datetime import datetime

class FaceFusionOperator:
    def __init__(self, api_url):
        self.api_url = api_url
        
    def health_check(self):
        """健康检查"""
        try:
            response = requests.get(f"{self.api_url}/health", timeout=10)
            return response.status_code == 200
        except:
            return False
            
    def get_metrics(self):
        """获取性能指标"""
        try:
            response = requests.get(f"{self.api_url}/metrics", timeout=5)
            return response.json()
        except:
            return {}
            
    def restart_service(self):
        """重启服务"""
        subprocess.run(["systemctl", "restart", "facefusion"], check=True)
        
    def cleanup_temp_files(self):
        """清理临时文件"""
        subprocess.run(["find", "/tmp", "-name", "facefusion_*", 
                       "-mtime", "+1", "-delete"], check=False)

8. 故障排查与恢复

8.1 常见故障处理

故障现象	可能原因	解决方案
GPU内存不足	并发过高/模型太大	调整execution_thread_count
推理速度慢	GPU驱动问题	更新NVIDIA驱动
视频处理失败	编码器不支持	检查FFmpeg配置
模型加载失败	网络问题	检查模型下载配置

8.2 日志分析指南

# 实时日志监控
tail -f /var/log/facefusion/app.log | grep -E "(ERROR|WARN)"

# 错误统计
grep "ERROR" /var/log/facefusion/app.log | awk '{print $4}' | sort | uniq -c | sort -nr

# 性能分析
grep "inference_time" /var/log/facefusion/perf.log | awk '{print $NF}' | sort -n | tail -10
