Hexo CI/CD自动化部署：从GitHub Actions到生产环境的完整流水线

前言

在现代软件开发中，持续集成和持续部署(CI/CD)已成为标准实践。对于技术博客而言，自动化部署不仅能提高发布效率，还能确保代码质量和稳定性。本文将详细介绍如何为Hexo博客构建完整的CI/CD流水线。

CI/CD基础概念

1. 核心概念

  • 持续集成(CI): 频繁集成代码变更，自动测试
  • 持续部署(CD): 自动部署通过测试的代码
  • 流水线: 自动化执行的一系列步骤

2. 工作流程

1
代码提交 → 自动测试 → 构建 → 部署 → 监控

GitHub Actions基础配置

1. 创建基础工作流

创建.github/workflows/deploy.yml：

最佳实践总结

1. 工作流设计原则

  • 自动化: 减少人工干预
  • 可重复: 每次构建结果一致
  • 可监控: 实时了解部署状态
  • 可回滚: 快速恢复到稳定版本

2. 安全检查清单

  • 所有依赖已更新到最新版本
  • 敏感信息使用GitHub Secrets
  • 部署前运行完整测试套件
  • 配置健康检查端点
  • 设置监控和告警
