This page documents the typical file system structure on an Aegir installation. It is intended to complement a related wiki page on Aegir Architecture. The following paths are based on an Aegir 0.4-x installation and assume that all directories are within the /var/aegir folder.

Platform permissions

Notes |
./* |
aegir:aegir
drwxr-xr-x |
aegir:aegir
-rw-r--r--
|
The webserver has no business writing or moving files in the Drupal codebase. |
| Inside ./sites/example.com: |
drushrc.php |
|
aegir:aegir
-r--------
|
Web server shouldn't be able to read drushrc.php, it's not a component of the Drupal site. |
settings.php |
|
aegir:www-data
-r--r-----
|
Web server can read this file, but otherwise tight control over this file which can contain sensitive information. |
libraries
modules
themes
|
aegir:aegir
drwxrwsr-x
|
aegir:aegir
-rw-r--r--
|
Because of the sticky bit (s) on the parent directory, each child directory will inherit attributes of the parent. The attribute that is consistently inherited is the group. This means that a developer in the "aegir" group can add files which will retain the "aegir" group ownership of the parent directory.
|
files
private
|
aegir:www-data
drwxrws---
|
|
Aegir sets these directories with a sticky bit (s) so that under certain conditions new folders and files will inherit parent permissions. There are only a few cases where this happens though. |
files/*
private/*
|
www-data:www-data
drwxr-sr-x
|
www-data:www-data
-rw-r--r--
|
The permissions shown here are how files and directories created by www-data will look. When verifying a platform, Aegir won't "correct" these files and directories to match the parents.
If you have trouble with permissions/ownership on these directories, you can safely run the following commands (in this case on the files directory):
# chown -R aegir:www-data /path/to/site/files/*
# chmod -R 775 /path/to/site/files/*
