- API文档: http://localhost:8080/doc.html

## 🧪 测试环境部署

### 1. 服务器准备
```bash
# 登录测试服务器
ssh user@test-server

# 创建项目目录
mkdir -p /opt/jiebanke
cd /opt/jiebanke
```

### 2. 部署脚本
```bash
#!/bin/bash
# deploy-test.sh

# 拉取最新代码
git pull origin develop

# 构建项目
cd backend-java
./build-services.sh

# 重启服务
docker-compose down
docker-compose up -d
```

### 3. 环境配置

# 服务器初始化
apt update && apt upgrade -y
apt install -y openjdk-17-jdk maven docker docker-compose
```

### 2. 数据库部署
```bash
# 安装MySQL
apt install -y mysql-server

# 安全配置
mysql_secure_installation

# 创建生产数据库
mysql -u root -p -e "CREATE DATABASE jiebanke CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;"

# 导入数据
mysql -u root -p jiebanke < scripts/init-database.sql
```

### 3. 应用部署
```bash
# 创建部署用户
adduser deploy
usermod -aG docker deploy

# 项目目录
mkdir -p /home/deploy/jiebanke
chown deploy:deploy /home/deploy/jiebanke
```

### 4. 自动化部署脚本

APP_DIR="/home/deploy/jiebanke"
BRANCH="main"

echo "🚀 开始部署 $APP_NAME..."

# 拉取代码
echo "📦 拉取最新代码..."
cd $APP_DIR
git fetch origin
git checkout $BRANCH
git reset --hard origin/$BRANCH

# 构建项目
echo "🔧 构建项目..."
cd backend-java
./build-services.sh

# 停止当前服务
echo "⏹️ 停止当前服务..."
docker-compose down

# 启动新服务
echo "▶️ 启动新服务..."
docker-compose up -d

echo "✅ 部署完成!"
echo "🌐 Eureka Dashboard: http://your-domain.com:8761"
echo "🌐 API Gateway: http://your-domain.com:8080"
```

### 5. Nginx 配置
```nginx
# /etc/nginx/sites-available/jiebanke
server {
    listen 80;
    server_name your-domain.com;
    
    # 反向代理到API网关
    location / {
        proxy_pass http://localhost:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}
```

### 6. SSL证书配置
```bash
# 安装Certbot
apt install -y certbot python3-certbot-nginx

# 获取SSL证书
certbot --nginx -d your-domain.com

# 自动续期
certbot renew --dry-run
```

## 📊 监控与日志

        - containerPort: 8761
---
apiVersion: v1
kind: Service
metadata:
  name: eureka-service
spec:
  selector:
    app: eureka
  ports:
  - port: 8761
    targetPort: 8761
  type: ClusterIP
```

## 🚨 故障排除

### 常见问题

1. **端口占用**
```bash
# 查找占用端口的进程
lsof -i :8080

# 杀死进程
kill -9 <PID>
```

2. **权限问题**
```bash
# 修改文件权限
chown -R deploy:deploy /home/deploy/jiebanke
chmod -R 755 /home/deploy/jiebanke
```

3. **数据库连接失败**
```bash
# 检查MySQL服务
systemctl status mysql

# 检查防火墙
ufw status
```

4. **Docker容器问题**
```bash
# 查看容器状态
docker-compose ps

# 查看容器日志
docker-compose logs <service-name>

# 重新构建容器
docker-compose build --no-cache
```

### 日志分析
```bash
# 查看错误日志
docker-compose logs -f --tail 100

# 查看特定服务日志
docker-compose logs -f user-service

# 数据库日志
tail -f /var/log/mysql/error.log
```

## 🎯 性能优化建议

### JVM调优
```bash
# 在Dockerfile中设置JVM参数
ENV JAVA_OPTS="-Xms512m -Xmx2g -XX:+UseG1GC -XX:MaxGCPauseMillis=200"
```

### 数据库连接池优化
```yaml
# 在application.yml中配置
spring:
  datasource:
    hikari:
      maximum-pool-size: 20
      minimum-idle: 5
      connection-timeout: 30000
      idle-timeout: 600000
      max-lifetime: 1800000
```

### Redis连接池优化
```yaml
# 在application.yml中配置
spring:
  redis:
    lettuce:
      pool:
        max-active: 20
        max-idle: 10
        min-idle: 5
        max-wait: 2000ms
```

### 负载均衡优化
```yaml
# 在application.yml中配置
ribbon:
  ConnectTimeout: 3000
  ReadTimeout: 10000
  MaxAutoRetriesNextServer: 1
  MaxAutoRetries: 0
```
