### 服务器角色说明

| 服务器 | IP 地址 | 角色 | 部署服务 |
|-------|---------|------|---------|
| Nginx + MPC 服务器 | 192.168.1.100 (公网) | API 网关 + MPC 核心 | Nginx, MPC-System (Go) |
| 后端服务器 | 192.168.1.111 (内网) | 业务微服务 | 所有 NestJS 微服务 + 基础设施 |

### 为什么 MPC-System 部署在 Nginx 服务器上？

**安全隔离原则**: MPC-System 是处理密钥分片的核心安全组件，与业务数据库隔离部署可以：
1. 减少攻击面 - 即使业务服务器被入侵，MPC 密钥分片仍然安全
2. 物理隔离 - 密钥分片和业务数据在不同机器上
3. 独立运维 - MPC 系统可以独立升级和维护

## 2. 服务端口规划

### 2.1 Nginx + MPC 服务器 (192.168.1.100)

| 服务名称 | 端口 | 说明 |
|---------|------|------|
| Nginx | 80, 443 | HTTP/HTTPS 反向代理 |
| MPC-System (Go) | 4000 | TSS 密钥生成、签名服务 |

### 2.2 后端服务器 (192.168.1.111)

| 服务名称 | 端口 | API 前缀 | 说明 |
|---------|------|----------|------|
| Identity Service | 3000 | `/api/v1` | 用户身份、认证、钱包创建 |
| MPC Service (NestJS) | 3001 | `/api/v1` | MPC 中间层，调用 MPC-System |
| Wallet Service | 3002 | `/api/v1` | 钱包余额、交易、充值 |
| Planting Service | 3003 | `/api/v1` | 认种业务 |
| Referral Service | 3004 | `/api/v1` | 推荐关系、分享链接 |
| Reward Service | 3005 | `/api/v1` | 挖矿奖励、收益 |
| Authorization Service | 3006 | `/api/v1` | 权限管理 (内部) |
| Leaderboard Service | 3007 | `/api` | 排行榜 |
| Reporting Service | 3008 | `/api/v1` | 遥测统计、报表 |
| Backup Service | 3009 | - | MPC 备份 (内部服务) |

### 2.3 MPC 调用链路

```
用户请求 → Identity Service (3000) → MPC Service (3001) → MPC-System (192.168.1.100:4000)
                                                                    ↓
                                                              TSS 密钥生成/签名
```

## 3. Nginx 配置文件

### 3.1 目录结构

在 Nginx 服务器上使用 `sites-available` / `sites-enabled` 标准结构：

```
/etc/nginx/
├── nginx.conf                         # 主配置文件
├── sites-available/                   # 可用站点配置
│   └── rwaapi.szaiai.com.conf        # API 网关配置
├── sites-enabled/                     # 已启用站点 (软链接)
│   └── rwaapi.szaiai.com.conf → ../sites-available/rwaapi.szaiai.com.conf
└── snippets/                          # 可复用配置片段
    ├── proxy-params.conf             # 代理参数
    ├── cors-params.conf              # CORS 跨域配置
    └── ssl-params.conf               # SSL 安全参数

/etc/letsencrypt/live/rwaapi.szaiai.com/   # Let's Encrypt SSL 证书 (自动管理)
├── fullchain.pem                          # 完整证书链
├── privkey.pem                            # 私钥
├── cert.pem                               # 服务器证书
└── chain.pem                              # 中间证书
```

**使用 `sites-available/sites-enabled` 的优势：**
- 快速启用/禁用站点：`ln -s` / `rm` 软链接
- 保留配置历史，方便回滚
- 多站点管理更清晰

### 3.2 主配置文件 `/etc/nginx/nginx.conf`

```nginx
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

events {
    worker_connections 1024;
    use epoll;
    multi_accept on;
}

http {
    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    log_format main '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for" '
                    'rt=$request_time uct="$upstream_connect_time" '
                    'uht="$upstream_header_time" urt="$upstream_response_time"';

    access_log /var/log/nginx/access.log main;

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    client_max_body_size 10m;

    # Gzip 压缩
    gzip on;
    gzip_vary on;
    gzip_proxied any;
    gzip_comp_level 6;
    gzip_types text/plain text/css text/xml application/json application/javascript
               application/xml application/xml+rss text/javascript;

    # 限流配置
    limit_req_zone $binary_remote_addr zone=api_limit:10m rate=10r/s;
    limit_conn_zone $binary_remote_addr zone=conn_limit:10m;

    # 加载已启用的站点配置
    include /etc/nginx/sites-enabled/*.conf;
}
```

### 3.3 代理参数配置 `/etc/nginx/snippets/proxy-params.conf`

```nginx
proxy_http_version 1.1;
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_set_header Connection "";

proxy_connect_timeout 60s;
proxy_send_timeout 60s;
proxy_read_timeout 60s;

proxy_buffering on;
proxy_buffer_size 4k;
proxy_buffers 8 4k;
proxy_busy_buffers_size 8k;
```

### 3.4 CORS 配置 `/etc/nginx/snippets/cors-params.conf`

```nginx
# CORS 预检请求处理
if ($request_method = 'OPTIONS') {
    add_header 'Access-Control-Allow-Origin' '*' always;
    add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS' always;
    add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization' always;
    add_header 'Access-Control-Max-Age' 1728000;
    add_header 'Content-Type' 'text/plain; charset=utf-8';
    add_header 'Content-Length' 0;
    return 204;
}

# CORS 响应头
add_header 'Access-Control-Allow-Origin' '*' always;
add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS' always;
add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization' always;
add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range' always;
```

### 3.5 SSL 安全参数 `/etc/nginx/snippets/ssl-params.conf`

```nginx
# SSL 会话配置
ssl_session_timeout 1d;
ssl_session_cache shared:SSL:50m;
ssl_session_tickets off;

# 现代 SSL 协议配置
ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384;
ssl_prefer_server_ciphers off;

# HSTS
add_header Strict-Transport-Security "max-age=63072000" always;
```

### 3.6 API 网关配置 `/etc/nginx/sites-available/rwaapi.szaiai.com.conf`

### 4.4 部署步骤

```bash
# ============================================
# 步骤 1: 克隆代码
# ============================================
cd /home/ceshi
git clone https://github.com/your-org/rwadurian.git
cd rwadurian/backend/mpc-system

# ============================================
# 步骤 2: 安装依赖
# ============================================
# 需要 root 权限
sudo bash scripts/deploy.sh install

# 脚本将自动安装:
# - Go 1.21 (从 go.dev 下载，使用 goproxy.cn 加速)
# - PostgreSQL 15
# - Redis 7
# - RabbitMQ 3

# ============================================
# 步骤 3: 配置环境变量
# ============================================
sudo vim /opt/mpc-system/config/mpc.env
```

**mpc.env 配置文件内容:**

```bash
# MPC-System 环境配置
# 请修改以下值为生产环境的安全密码

# 环境标识
ENVIRONMENT=production

# PostgreSQL 数据库
POSTGRES_USER=mpc_user
POSTGRES_PASSWORD=your_secure_postgres_password_here
MPC_DATABASE_HOST=localhost
MPC_DATABASE_PORT=5432
MPC_DATABASE_USER=mpc_user
MPC_DATABASE_PASSWORD=your_secure_postgres_password_here
MPC_DATABASE_DBNAME=mpc_system
MPC_DATABASE_SSLMODE=disable

# Redis 缓存 (留空表示不需要密码)
REDIS_PASSWORD=
MPC_REDIS_HOST=localhost
MPC_REDIS_PORT=6379
MPC_REDIS_PASSWORD=

# RabbitMQ 消息队列
RABBITMQ_USER=mpc_user
RABBITMQ_PASSWORD=your_secure_rabbitmq_password_here
MPC_RABBITMQ_HOST=localhost
MPC_RABBITMQ_PORT=5672
MPC_RABBITMQ_USER=mpc_user
MPC_RABBITMQ_PASSWORD=your_secure_rabbitmq_password_here

# JWT 配置 (至少 32 字符)
JWT_SECRET_KEY=your_super_secure_jwt_secret_key_at_least_32_characters
MPC_JWT_SECRET_KEY=your_super_secure_jwt_secret_key_at_least_32_characters
MPC_JWT_ISSUER=mpc-system

# 主加密密钥 (64 位十六进制 = 256 位密钥，用于加密密钥分片)
CRYPTO_MASTER_KEY=your_64_hex_characters_master_key_here
MPC_CRYPTO_MASTER_KEY=your_64_hex_characters_master_key_here

# API 认证密钥 (与 mpc-service 配置的 MPC_API_KEY 一致)
MPC_API_KEY=your_very_secure_api_key_at_least_32_characters

# 允许访问的 IP 地址 (后端服务器)
ALLOWED_IPS=192.168.1.111

# 服务配置
MPC_SERVER_ENVIRONMENT=production
MPC_SERVER_HTTP_PORT=8080
MPC_SERVER_GRPC_PORT=50051

# 内部服务地址
SESSION_COORDINATOR_ADDR=localhost:50051
MESSAGE_ROUTER_ADDR=localhost:50052
```

```bash
# ============================================
# 步骤 4: 编译并配置服务
# ============================================
sudo bash scripts/deploy.sh build

# 此步骤会:
# - 编译所有 Go 服务到 /opt/mpc-system/bin/
# - 创建 systemd 服务文件
# - 配置 PostgreSQL 数据库和用户
# - 配置 Redis
# - 配置 RabbitMQ 用户
# - 运行数据库迁移

# ============================================
# 步骤 5: 启动服务
# ============================================
sudo bash scripts/deploy.sh start

# ============================================
# 步骤 6: 验证部署
# ============================================
# 查看服务状态
sudo bash scripts/deploy.sh status

# 健康检查
curl http://localhost:8080/health

# 查看日志
sudo bash scripts/deploy.sh logs mpc-account
```

### 4.5 配置 Nginx 反向代理 (端口 4000)

为了保持与 Docker 部署相同的端口映射 (4000 → 8080)，配置 Nginx:

```bash
# 创建 MPC 代理配置
cat > /etc/nginx/conf.d/mpc-proxy.conf << 'EOF'
# MPC-System 内部代理
# 将外部端口 4000 代理到内部 8080

server {
    listen 4000;
    server_name localhost;

    location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_http_version 1.1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        # 仅允许后端服务器访问
        allow 192.168.1.111;
        deny all;
    }
}
EOF

# 测试并重载 Nginx
nginx -t && nginx -s reload
```

或者直接使用 iptables 端口转发:

```bash
# 端口转发: 4000 → 8080
iptables -t nat -A PREROUTING -p tcp --dport 4000 -j REDIRECT --to-port 8080
iptables -t nat -A OUTPUT -p tcp --dport 4000 -j REDIRECT --to-port 8080

# 保存规则
iptables-save > /etc/iptables/rules.v4
```

### 4.6 服务端口说明

| 服务 | 端口 | 说明 |
|------|------|------|
| mpc-account | 8080 (→ 4000) | 对外 API 入口，供 mpc-service 调用 |
| mpc-session-coordinator | 50051 | 会话协调 gRPC (内部) |
| mpc-message-router | 50052 | 消息路由 gRPC (内部) |
| mpc-server-party-1/2/3 | 8081-8083 | TSS 参与方 HTTP (内部) |
| PostgreSQL | 5432 | 数据库 (内部) |
| Redis | 6379 | 缓存 (内部) |
| RabbitMQ | 5672 | 消息队列 (内部) |

> **注意**: 生产环境仅对外暴露端口 4000 (通过 Nginx 或 iptables 代理到 8080)

### 4.7 MPC-System API 端点

Account Service (端口 4000/8080) 对外提供以下 API:

| 端点 | 方法 | 说明 |
|------|------|------|
| `/health` | GET | 健康检查 |
| `/api/v1/account/create` | POST | 创建 MPC 账户 (触发密钥生成) |
| `/api/v1/account/sign` | POST | 请求签名 |
| `/api/v1/account/recovery` | POST | 账户恢复 |

### 4.8 防火墙配置

```bash
# 只允许后端服务器 (192.168.1.111) 访问 MPC-System 端口 4000/8080
iptables -A INPUT -p tcp --dport 4000 -s 192.168.1.111 -j ACCEPT
iptables -A INPUT -p tcp --dport 4000 -j DROP
iptables -A INPUT -p tcp --dport 8080 -s 192.168.1.111 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP

# 保存规则
iptables-save > /etc/iptables/rules.v4
```

### 4.9 运维命令

```bash
cd /home/ceshi/rwadurian/backend/mpc-system

# 查看服务状态
sudo bash scripts/deploy.sh status

# 或使用 systemctl
systemctl status mpc-account
systemctl status mpc-session-coordinator
systemctl status mpc-message-router
systemctl status mpc-server-party-1
systemctl status mpc-server-party-2
systemctl status mpc-server-party-3

# 查看日志
sudo bash scripts/deploy.sh logs mpc-account
# 或
journalctl -u mpc-account -f
tail -f /opt/mpc-system/logs/mpc-account.log

# 重启单个服务
systemctl restart mpc-account

# 重启所有 MPC 服务
sudo bash scripts/deploy.sh restart

# 停止所有 MPC 服务
sudo bash scripts/deploy.sh stop

# 启动所有 MPC 服务
sudo bash scripts/deploy.sh start

# 重新编译 (代码更新后)
cd /home/ceshi/rwadurian/backend/mpc-system
git pull
sudo bash scripts/deploy.sh build
sudo bash scripts/deploy.sh restart
```

### 4.10 目录结构

安装后的目录结构:

```
/opt/mpc-system/
├── bin/                    # 编译后的可执行文件
│   ├── account-service
│   ├── session-coordinator
│   ├── message-router
│   └── server-party
├── config/
│   └── mpc.env             # 环境配置文件
├── data/                   # 数据目录

│   └── 001_init_schema.up.sql
└── pids/                   # PID 文件目录
```

### 4.11 故障排查

```bash
# 检查服务是否在运行
sudo bash scripts/deploy.sh status

# 检查端口是否监听
ss -tlnp | grep -E '8080|50051|50052'

# 检查 PostgreSQL 连接
sudo -u postgres psql -c "SELECT 1;"

# 检查 Redis 连接
redis-cli ping

# 检查 RabbitMQ 连接
rabbitmqctl status

# 查看服务错误日志
tail -100 /opt/mpc-system/logs/mpc-account.error.log

# 手动启动服务调试
sudo -u mpc /opt/mpc-system/bin/account-service
```

### 5.2 数据库初始化脚本

在 192.168.1.111 服务器上创建 `/opt/rwadurian/scripts/init-databases.sql`:

```sql
-- 创建所有微服务数据库
CREATE DATABASE rwa_identity;
CREATE DATABASE rwa_mpc;
CREATE DATABASE rwa_wallet;
CREATE DATABASE rwa_planting;
CREATE DATABASE rwa_referral;
CREATE DATABASE rwa_reward;
CREATE DATABASE rwa_authorization;
CREATE DATABASE rwa_leaderboard;
CREATE DATABASE rwa_reporting;
CREATE DATABASE rwa_backup;
```

### 5.3 环境变量文件

在 192.168.1.111 服务器上创建 `/opt/rwadurian/.env`:

```bash
# Database
DB_PASSWORD=your_secure_database_password_here

# JWT (所有服务共享)
JWT_SECRET=your_super_secure_jwt_secret_at_least_32_characters

# Redis
REDIS_PASSWORD=your_secure_redis_password

# Service JWT (服务间通信)
SERVICE_JWT_SECRET=your_service_jwt_secret_for_internal_calls

# Wallet Encryption
WALLET_ENCRYPTION_SALT=your_wallet_encryption_salt
```

## 6. 部署步骤

### 6.1 Nginx + MPC 服务器 (192.168.1.100) 配置

```bash
# ============================================
# 步骤 1: 安装 Nginx 和 Let's Encrypt
# ============================================
apt update && apt install -y nginx certbot python3-certbot-nginx

# ============================================
# 步骤 2: 创建目录结构
# ============================================
mkdir -p /etc/nginx/sites-available
mkdir -p /etc/nginx/sites-enabled
mkdir -p /etc/nginx/snippets

# ============================================
# 步骤 3: 获取 SSL 证书 (必须在配置 HTTPS 站点之前)
# ============================================
# 重要：在全新系统上，必须先获取证书，否则 Nginx 配置引用证书路径会报错

# 方式 A: 使用 standalone 模式 (推荐用于首次部署)
# 临时停止 Nginx (如果正在运行)
systemctl stop nginx
# 获取证书
certbot certonly --standalone -d rwaapi.szaiai.com
# 证书保存位置:
#   /etc/letsencrypt/live/rwaapi.szaiai.com/fullchain.pem  (完整证书链)
#   /etc/letsencrypt/live/rwaapi.szaiai.com/privkey.pem    (私钥)

# 方式 B: 使用 webroot 模式 (需要先配置 HTTP 站点)
# 1. 先配置一个简单的 HTTP 站点 (不含 SSL)
# 2. certbot certonly --webroot -w /var/www/html -d rwaapi.szaiai.com

# ============================================
# 步骤 4: 复制 Nginx 配置文件
# ============================================
# 将上面的配置文件复制到对应目录:
# - nginx.conf → /etc/nginx/nginx.conf
# - proxy-params.conf → /etc/nginx/snippets/proxy-params.conf
# - cors-params.conf → /etc/nginx/snippets/cors-params.conf
# - ssl-params.conf → /etc/nginx/snippets/ssl-params.conf
# - rwaapi.szaiai.com.conf → /etc/nginx/sites-available/rwaapi.szaiai.com.conf

# ============================================
# 步骤 5: 启用站点
# ============================================
# 禁用默认站点 (如果存在)
rm -f /etc/nginx/sites-enabled/default

# 创建软链接启用站点
ln -s /etc/nginx/sites-available/rwaapi.szaiai.com.conf /etc/nginx/sites-enabled/

# ============================================
# 步骤 6: 测试并启动 Nginx
# ============================================
# 测试配置 (此时证书已存在，不会报错)
nginx -t

# 启动 Nginx
systemctl start nginx
systemctl enable nginx

# ============================================
# 步骤 7: 配置证书自动续期
# ============================================
# Let's Encrypt 证书有效期 90 天，certbot 已自动配置 systemd timer
# 验证自动续期任务:
systemctl list-timers | grep certbot

# 手动测试续期 (不会实际续期，只是测试流程):
certbot renew --dry-run

# ============================================
# 站点管理命令 (日常运维)
# ============================================
# 禁用站点: rm /etc/nginx/sites-enabled/rwaapi.szaiai.com.conf && nginx -s reload
# 启用站点: ln -s /etc/nginx/sites-available/rwaapi.szaiai.com.conf /etc/nginx/sites-enabled/ && nginx -s reload
# 重新加载: nginx -s reload
# 查看状态: systemctl status nginx
```
