Answer 1

I had exactly the same problem. To solve it, I just sourced /etc/environment inside /etc/apache2/envvars.

The content of /etc/environment:

export MY_PROJECT_PATH=/var/www/my-project
export MY_PROJECT_ENV=production
export MY_PROJECT_MAIL=support@my-project.com

The content of /etc/apache2/envvars:

# Load all the system environment variables.
. /etc/environment

Now, I'm able to use these variables in the Apache Virtual Host config files and in PHP.

Here's an example of an Apache virtual host:

  ServerName my-project.com
  ServerAlias www.my-project.com
  ServerAdmin ${MY_PROJECT_MAIL}
  UseCanonicalName On

  DocumentRoot ${MY_PROJECT_PATH}/www

  # Error log.
  ErrorLog ${APACHE_LOG_DIR}/my-project.com_error.log
  LogLevel warn

  # Access log.
  
    LogFormat "%h %l %u %t \"%m %>U%q\" %>s %b %D" clean_url_log_format
    CustomLog ${APACHE_LOG_DIR}/my-project.com_access.log clean_url_log_format
  

  # DocumentRoot directory
  
    # Disable .htaccess rules completely, for better performance.
    AllowOverride None
    Options FollowSymLinks Includes
    Order deny,allow
    Allow from All

    Include ${MY_PROJECT_PATH}/config/apache/inc.mime-types.conf
    Include ${MY_PROJECT_PATH}/config/apache/inc.cache-control.conf

    # Rewrite rules.
    
      RewriteEngine on
      RewriteBase /

      # Include all the common rewrite rules (for http and https).
      Include ${MY_PROJECT_PATH}/config/apache/inc.rewriterules-shared.conf
    
  

And this is an example of how to access them with PHP:
