AWS Elastic Beanstalk Drupal 8 安装错误：未能创建符号链接“站点/默认/文件”：

【中文标题】AWS Elastic Beanstalk Drupal 8 安装错误：未能创建符号链接“站点/默认/文件”：【英文标题】：AWS Elastic Beanstalk Drupal 8 Install Error: failed to create symbolic link 'sites/default/files': 【发布时间】：2018-07-23 05:12:21 【问题描述】：解决方案更新： 我没有压缩目录，而是选择了目录中的所有文件和文件夹并压缩了它们。然后我将压缩文件夹的权限更改为 777。 另外，在 efs-mount.config 文件中，我将命令更改为：
1chown:
command: "chown webapp:webapp /drupalfiles"
2create:
command: "sudo -u webapp mkdir -p sites/default/files"
3link:
command: "sudo -u webapp ln -s /drupalfiles sites/default/files"
原始问题：我对 AWS 和 Drupal 都很陌生。
我正在尝试按照以下文档在 AWS Elastic Beanstalk 上安装 Drupal 8：
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/php-hadrupal-tutorial.html#php-hadrupal-tutorial-launch
当我进入“启动 Elastic Beanstalk 环境”时，我不断收到此错误，并且我永远无法进入 Drupal 8 安装屏幕。
实例上的命令失败。返回码：1 输出：ln：未能创建符号链接 'sites/default/files'：没有这样的文件或目录。 elastic-beanstalk/.ebextensions/efs-mount.config 中的 container_command 2link 失败。有关更多详细信息，请使用控制台或 EB CLI 检查 /var/log/eb-activity.log。
我已确保此文件夹和所有递归文件夹权限设置为读写。

【问题讨论】：
单实例还是负载均衡？另外，eb 活动日志是什么样的？ 您是否已经设置了 RDS 实例？ 单实例。是的，RDS 已设置完毕。 您可以分享您的efs-mount.config 文件的内容吗？
您能否在config 文件中添加一个额外的步骤，例如：container_commands: 1chown: command: "chown webapp:webapp /drupalfiles" 2create: command: "sudo -u webapp mkdir -p sites/default/files" 3link: command: "sudo -u webapp ln -s /drupalfiles sites/default/files"
【参考方案1】：
使用解决方案更新： 在 efs-mount.config 文件中，我将命令更改为：
1chown:
command: "chown webapp:webapp /drupalfiles"
2create:
command: "sudo -u webapp mkdir -p sites/default/files"
3link:
command: "sudo -u webapp ln -s /drupalfiles sites/default/files"
我使用命令更改了文件夹的权限：
chmod -R 777 /drupal-beanstalk
我没有压缩目录本身，而是选择了目录中的所有文件和文件夹并压缩了它们。我使用以下命令从压缩文件夹中删除了 .MACOSX：
zip -d filename.zip __MACOSX/\*
将此文件夹上传到 AWS Elastic Beanstalk 时，应用程序处于绿色运行状态，并且 URL 打开了 Drupal 安装页面。
