#!/bin/bash
#
# 脚本名称: update_acme_cert.sh
# 功能: 自动检测并更新 ACME SSL 证书
# 功能: 自动检测并更新 ACME SSL 证书（增强版）
# 作者: Assistant
# 日期: 2026-03-03
# 日期: 2026-03-23
# 用法:
# sudo ./update_acme_cert.sh
#
# 交互式输入：
# - 域名 (例如: example.com)
#
# 新增增强功能:
# 1. 自动安装/升级 acme.sh（如未安装）
# 2. 自动备份旧证书配置
# 3. nginx 配置冲突智能清理
# 4. 域名可达性自动检测
# 5. 证书更新失败自动重试（最多3次，指数退避）
# 6. 多维度最终验证（HTTPS访问、HTTP跳转、SSL证书）
# 7. 详细的诊断建议和排查步骤
#
# 前提条件:
# - 需要 root 权限运行
# - 需要安装 nginx
# - 需要开放 80 和 443 端口
# - 域名需正确解析到本服务器
#
# sudo chmod +x update_acme_cert.sh
