AWS Elastic Beanstalk Drupal 8安装错误：无法创建符号链接'sites / default / files'：

Question

更新解决方案：我没有压缩目录，而是选择目录中的所有文件和文件夹并压缩它们。然后我将zipped文件夹的权限更改为777.此外，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都很新。

我正在尝试按照此文档在AWS Elastic Beanstalk上安装Drupal 8：

https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/php-hadrupal-tutorial.html#php-hadrupal-tutorial-launch

当我开始“启动Elastic Beanstalk环境”时，我不断得到这个错误，我永远无法进入Drupal 8安装屏幕。

命令在实例上失败。返回码：1输出：ln：无法创建符号链接'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。

我已确保将此文件夹和所有递归文件夹权限设置为读取和写入。

Answer 1

更新解决方案： 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"

我使用以下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对其进行了压缩。我使用以下命令从压缩文件夹中删除了.MACOSX：

zip -d filename.zip __MACOSX/\*

将此文件夹上载到AWS Elastic Beanstalk时，该应用程序为绿色健康状况，URL打开了Drupal安装页面。
