问题：Vite开发服务器经常崩溃导致前端无法访问 解决方案： 1. PM2稳定模式（推荐）： - ecosystem.config.js: PM2配置文件 - start_with_pm2.sh: PM2一键启动脚本 - 自动重启崩溃服务，内存限制500MB（前端）/1GB（后端） - 日志管理，所有日志保存到logs目录 2. 保活监控模式（备选）： - keep_alive.sh: 每10秒检测服务状态 - 发现崩溃自动重启前端/后端服务 3. 更新README.md：详细说明三种启动方式及优劣 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
