/usr/sbin/apache2 flags=(complain,attach_disconnected) {
# This profile is completely permissive.
# It is designed to target specific applications using mod_apparmor,
# hats, and the apache2.d directory.
#
# In order to enable this profile, you must:
#
# 0- Stop apache:
# sudo service apache2 stop
#
# 1- Enable the profile:
# sudo aa-enforce /etc/apparmor.d/usr.sbin.apache2
#
# 2- Load the mpm_prefork and mod_apparmor modules:
# sudo a2dismod <other non-prefork mpm>
# sudo a2enmod mpm_prefork
# sudo a2enmod apparmor
# sudo service apache2 restart
#
# 3- Place an appropriate profile containing the desired hat in the
# /etc/apparmor.d/apache2.d directory. Such profiles must include
# the "apache2-common" abstraction:
#
# ^example.com flags=(complain) {
# #include <abstractions/apache2-common>
# /var/www/html/ r,
# /var/www/html/** r,
# /var/log/apache2/*.log w,
# }
#
# 4- Use the "AADefaultHatName" apache configuration option to specify a
# hat to be used for a given apache virtualhost or "AAHatName" for
# a given apache directory or location directive:
#
# <VirtualHost example.com:80>
# <IfModule mod_apparmor.c>
# AADefaultHatName example.com
# </IfModule>
# ...
# </VirtualHost>
#
#
# There is an example profile for phpsysinfo included in the
# apparmor-profiles package. To try it:
#
# 1- Install the phpsysinfo and the apparmor-profiles packages:
# sudo apt-get install phpsysinfo apparmor-profiles
#
# 2- Enable the main apache2 profile
# sudo aa-enforce /etc/apparmor.d/usr.sbin.apache2
#
# 3- Configure apache with the following (or similar):
# Alias /phpsysinfo /usr/share/phpsysinfo
# <Location /phpsysinfo>
# <IfModule mod_apparmor.c>
# AAHatName phpsysinfo
# </IfModule>
#
# # adjust as necessary:
# Options None
# Require local
# Require ip 192.168.0.0/16
# </Location>
#
#include <abstractions/base>
#include <abstractions/nameservice>
# Send signals to all hats.
