1、创建一个脚本文件setup-elk.sh

#!/bin/bash# =================================================================
# ELK Stack 自动化部署脚本 (for Docker Compose)
#
# 功能:
# 1. 创建标准的项目目录结构。
# 2. 自动生成 docker-compose.yml, filebeat.yml, logstash.conf。
# 3. 提供清晰的后续操作指引。
#
# 使用方法:
# 1. chmod +x setup-elk.sh
# 2. ./setup-elk.sh
# =================================================================# 定义颜色常量，让输出更美观
