Linux Aegir:调用hook drush_db_pre_provision_backup后，无法从mysqldump生成数据库备份

我在Debian服务器Jessie with（Aegir3、Drush 7.1.0、provision 7.x-3.4、hostmaster 7.x-3.4）上手动安装了Aegir软件包，除了备份功能外，一切都很顺利，下面是我所做的：

我激活了托管站点备份管理器模块，以自动备份我的网站

*********我无法在/var/aegir中安装aegir（因为我没有该服务器上其他目录的权限），但它安装了/production/my_aegir_user，该用户拥有所有aegir权限用户********

使用Aegir安装新站点后，当备份任务运行时，它会失败，并显示以下日志：

****my aegir root is not /var/aegir, but it is at /production/my_aegir_user

主要错误似乎是：

fopen（/production/my_aegir_user/platforms/template uni to/sites/www.mydomain.com/database.sql）： 无法打开流：权限被拒绝mysql。php:227

然而，可能还有其他原因。找到它的最佳方法是在调试模式下运行任务

例如，作为“aegir”用户：

drush @example.org provision-backup --debug

PS：我偶然发现这个问题，因为我遇到了类似的问题。您可能会有更好的机会获得回复（并将您的问题标记为“aegir”）。

嗨，bgm，谢谢您的回答，我会核实并让您知道。他们一直在关闭该网站上的aegir问题，因为它们不是特定于Drupal的（奇怪的是）。所以我认为这是目前最好的网站。
