1. 首先，将index.html文件上传到AWS Elastic Beanstalk。
2. 在AWS Elastic Beanstalk控制台上创建一个新的环境，选择“Web服务器环境”并使用“Single Instance”选项。
3. 通过 Elastic Beanstalk 控制台或者 AWS CLI 安装 Apache web 服务器。
4. 编辑 Apache 配置文件 /etc/httpd/conf/httpd.conf , 将DocumentRoot 修改为 index.html所在的路径。
5. 重启 Apache 服务器并访问网站，确保已通过“http://<您的 Elastic Beanstalk 网址>/index.html”访问。
