+部署脚本会自动配置SSL证书自动续期任务：
+
+```bash
+# 部署脚本会自动添加以下cron任务
+0 0,12 * * * certbot renew --quiet --post-hook 'docker restart novalon-nginx'
+```
+
+**手动配置自动续期**（如果需要）:
+
 ```bash
 # 添加cron任务
-0 0,12 * * * certbot renew --quiet
+(crontab -l 2>/dev/null; echo "0 0,12 * * * certbot renew --quiet --post-hook 'docker restart novalon-nginx'") | crontab -
+
+# 验证cron任务
+crontab -l
+
+# 手动测试续期
+certbot renew --dry-run
 ```
 
+**自动续期说明**:
+- 每天凌晨0点和中午12点自动检查证书续期
+- 证书到期前30天内才会实际续期
+- 续期成功后自动重启nginx容器以加载新证书
+- 续期过程静默执行，不产生输出
+- 续期失败时不会影响现有证书使用
