Apache HTTP 服务器远程管理图形界面工具

功能描述:
    本脚本提供基于 Tkinter 的图形用户界面，用于远程管理 Apache HTTP 服务器 (httpd)。
    通过 SSH 连接到远程服务器，实现 Apache 服务的启动、停止、状态查询和日志查看操作，
    为 Web 服务器运维人员提供直观便捷的服务管理工具。

技术实现:
    - 使用 Tkinter 构建桌面图形用户界面
    - 使用 paramiko 库建立 SSH 连接和远程命令执行
    - 采用 systemctl 命令管理 systemd 服务
    - 使用 pack() 布局管理器组织界面元素
    - 通过 ScrolledText 组件显示日志内容

界面组件设计:
    1. 状态标签 - 显示当前服务状态提示文本
    2. 状态文本框 - 显示 "Running" 或 "Not Running" 状态
    3. 状态检查按钮 - 执行 systemctl status httpd 命令
    4. 启动服务按钮 - 执行 systemctl start httpd 命令
    5. 停止服务按钮 - 执行 systemctl stop httpd 命令
    6. 查看日志按钮 - 显示 Apache 访问日志内容
