linux - Aegir:调用 hook drush_db_pre_provision_backup 后无法从 mysqldump 生成数据库备份

Question

我在 Debian 服务器 Jessie 上手动安装了 Aegir 包(Aegir3，Drush 7.1.0，provision 7.x-3.4，hostmaster 7.x-3.4)，一切都很顺利，除了备份功能，这就是我完成了:

我激活了托管站点备份管理器模块来自动备份我的网站。

*********我无法在/var/aegir 中安装 aegir(因为我对该服务器上的其他目录没有权限)，但它安装了/production/my_aegir_user，其中包含所有 aegir特权用户*********

使用 Aegir 安装新站点后，当备份任务运行时，它失败并显示以下日志:

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

Answer 1

主要错误似乎是:

fopen(/production/my_aegir_user/platforms/template-uni-to/sites/www.mydomain.com/database.sql): failed to open stream: Permission denied mysql.php:227

但是，可能还有其他原因。找到它的最佳方法是在 Debug模式下运行任务。

例如，作为“aegir”用户:

drush @example.org provision-backup --debug

PS:我偶然发现了这个问题，因为我遇到了类似的问题。您可能有更好的机会在 https://drupal.stackexchange.com/ 上获得回复(并用“aegir”标记您的问题)。
