====== 🔧 DV IT Infrastructure Platform - 故障排查指南 ======

**更新日期**: 2025年1月  
**项目**: DV IT Infrastructure Platform  
**基于**: 生产环境实际故障排查经验

===== 🎯 故障排查概述 =====

==== 排查原则 ====
  * **系统性排查**: 从网络→容器→服务→应用逐层排查
  * **日志优先**: 优先查看容器和服务日志
  * **配置验证**: 检查配置文件和环境变量
  * **网络隔离**: 验证Docker网络和Traefik路由

==== 常用命令 ====
<code bash>
# 查看所有容器状态
docker ps -a

# 查看容器日志
docker logs <container_name>

# 查看网络
docker network ls
docker network inspect <network_name>

# 查看Traefik路由
docker logs traefik

# 检查端口
netstat -tlnp | grep :80
netstat -tlnp | grep :443
</code>
