如何在部署后脚本中将更改目录设置为Amazon Elastick Beanstack上PHP应用程序所在的目录

Question

我为Amazon Elastick Beanstack上现有的PHP应用程序创建了部署后脚本。 该脚本已在远程计算机上正确启动，但是当前目录可能不是应用程序所在的目录。

如何更改路径以获取PHP应用程序在Amazon Elastick Beanstack实例上的安装位置？

EBextension文件：

commands:
  create_post_dir:
    command: "mkdir /opt/elasticbeanstalk/hooks/appdeploy/post"
    ignoreErrors: true
files:
  "/opt/elasticbeanstalk/hooks/appdeploy/post/99_change_access_rights.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/usr/bin/env bash
      # cd $EB_CONFIG_APP_CURRENT
      chmod 777 wp-content/plugins/wp-scss/cache
      chmod 777 wp-content/themes/XXXX/css

您需要指定完整路径：
... chmod 777 /var/app/current/wp-content/plugins/wp-scss/cache ...
