DesignHub 公网服务器部署指南

服务器信息：

  • IP: 45.192.99.48
  • 端口: 22
  • 用户名: root
  • 密码: 1blZllMIp7
  • 系统: CentOS Stream 9

快速部署脚本

已创建自动化部署脚本：deploy_to_public_server.sh

执行方式：

cd /Users/lanmu/Desktop/qiangdanxitong
bash deploy_to_public_server.sh

手动部署步骤（如果脚本失败）

第一步：连接服务器

ssh root@45.192.99.48
# 密码: 1blZllMIp7

第二步：安装系统依赖

# 安装基础工具
dnf install -y curl wget git unzip

# 安装 Java 17
dnf install -y java-17-openjdk java-17-openjdk-devel

# 安装 Maven
dnf install -y maven

# 安装 MySQL
dnf install -y mysql-server mysql
systemctl enable mysqld
systemctl start mysqld

# 设置 MySQL root 密码
mysqladmin -u root password "DesignHub@2025_Root"

# 安装 Redis
dnf install -y redis
systemctl enable redis
systemctl start redis

# Nginx 和 Node.js/pnpm 已安装，跳过

第三步：创建目录结构

mkdir -p /opt/designhub/{backend,frontend,logs,uploads}

第四步：配置 MySQL 数据库

mysql -uroot -pDesignHub@2025_Root << 'EOF'
CREATE DATABASE IF NOT EXISTS designhub CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER IF NOT EXISTS 'designhub'@'localhost' IDENTIFIED BY 'DesignHub@2025_DB';
GRANT ALL PRIVILEGES ON designhub.* TO 'designhub'@'localhost';
FLUSH PRIVILEGES;
EOF

第五步：上传代码

方式1：使用 rsync（推荐）

在本地执行：

# 安装 sshpass（Mac）
brew install hudochenkov/sshpass/sshpass

# 上传后端代码
sshpass -p '1blZllMIp7' rsync -avz \
    --exclude='target' --exclude='*.class' \
    -e "ssh -o StrictHostKeyChecking=no" \
    backend/ root@45.192.99.48:/opt/designhub/backend/

# 上传前端代码
sshpass -p '1blZllMIp7' rsync -avz \
    --exclude='node_modules' --exclude='dist' \
    -e "ssh -o StrictHostKeyChecking=no" \
    frontend/ root@45.192.99.48:/opt/designhub/frontend/

# 上传数据库SQL文件（如果有）
sshpass -p '1blZllMIp7' scp -o StrictHostKeyChecking=no \
    database/*.sql root@45.192.99.48:/tmp/

方式2：使用 scp

# 上传整个项目目录
sshpass -p '1blZllMIp7' scp -r \
    -o StrictHostKeyChecking=no \
    backend root@45.192.99.48:/opt/designhub/

sshpass -p '1blZllMIp7' scp -r \
    -o StrictHostKeyChecking=no \
    frontend root@45.192.99.48:/opt/designhub/

第六步：导入数据库（如果需要）

# 在服务器上执行
cd /tmp
mysql -uroot -pDesignHub@2025_Root designhub < create_s3_config.sql
# 导入其他SQL文件...

第七步：配置后端

cd /opt/designhub/backend

# 创建生产环境配置
cat > src/main/resources/application-prod.yml << 'EOF'

  datasource:
    url: jdbc:mysql://localhost:3306/designhub?useUnicode=true&characterEncoding=utf8mb4&useSSL=false&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true

# 构建后端
mvn clean package -DskipTests

# 复制JAR文件
cp target/designhub-backend-1.0.0.jar /opt/designhub/designhub.jar

第八步：配置前端

cd /opt/designhub/frontend

# 创建生产环境配置
cat > .env.production << 'EOF'
VITE_APP_BASE_API=http://45.192.99.48/api
VITE_APP_TITLE=DesignHub
VITE_APP_VERSION=6.0
EOF

# 安装依赖
pnpm install

# 构建
pnpm build

第九步：配置系统服务

# 创建后端服务
cat > /etc/systemd/system/designhub-backend.service << 'EOF'

# 重新加载 systemd
systemctl daemon-reload

# 测试 Nginx 配置
nginx -t

# 重启 Nginx
systemctl restart nginx
systemctl enable nginx

第十步：启动后端服务

# 启动后端服务
systemctl start designhub-backend
systemctl enable designhub-backend

# 查看状态
systemctl status designhub-backend

# 查看日志
tail -f /opt/designhub/logs/application.log

验证部署

检查服务状态

# 检查后端服务
systemctl status designhub-backend

# 检查 MySQL
systemctl status mysqld

# 检查 Redis
systemctl status redis

# 检查 Nginx
systemctl status nginx

测试访问

查看日志

# 后端日志
tail -f /opt/designhub/logs/application.log

# 后端错误日志
tail -f /opt/designhub/logs/backend-error.log

# Nginx 访问日志
tail -f /opt/designhub/logs/nginx-access.log

# Nginx 错误日志
tail -f /opt/designhub/logs/nginx-error.log

常用命令

服务管理

# 重启后端
systemctl restart designhub-backend

# 停止后端
systemctl stop designhub-backend

# 查看后端日志
journalctl -u designhub-backend -f

# 重启 Nginx
systemctl restart nginx

数据库管理

# 连接数据库
mysql -u designhub -pDesignHub@2025_DB designhub

# 备份数据库
mysqldump -u designhub -pDesignHub@2025_DB designhub > backup.sql

# 恢复数据库
mysql -u designhub -pDesignHub@2025_DB designhub < backup.sql

故障排查

后端无法启动

  1. 检查 Java 版本：java -version
  2. 检查 JAR 文件：ls -lh /opt/designhub/designhub.jar
  3. 检查日志：tail -100 /opt/designhub/logs/backend-error.log
  4. 手动运行：cd /opt/designhub && java -jar designhub.jar --spring.profiles.active=prod

数据库连接失败

  1. 检查 MySQL 状态：systemctl status mysqld
  2. 测试连接：mysql -u designhub -pDesignHub@2025_DB designhub
  3. 检查配置文件：cat /opt/designhub/backend/src/main/resources/application-prod.yml

前端无法访问

  1. 检查 Nginx 状态：systemctl status nginx
  2. 检查 Nginx 配置：nginx -t
  3. 检查前端文件：ls -lh /opt/designhub/frontend/dist/
  4. 查看 Nginx 错误日志：tail -100 /opt/designhub/logs/nginx-error.log

注意事项

  1. 安全建议：

    • 修改 MySQL root 密码
    • 修改 Redis 密码
    • 修改 JWT secret
    • 配置防火墙规则

  2. 性能优化：

    • 根据服务器配置调整 JVM 参数（-Xms, -Xmx）
    • 配置 MySQL 连接池大小
    • 配置 Redis 连接池

  3. 备份策略：

    • 定期备份数据库
    • 备份配置文件
    • 备份上传的文件
