Apache 2 MPM Event with PHP-FPM, FCGID and SUEXEC on Debian Jessie

The goal of this setup is having a high-performance state-of-the-art deployment of Apache and PHP while being compatible with legacy applications.

  • Apache Event MPM engine handles requests asynchronously, instead of using a dedicated thread or process per request.

  • PHP-FPM is a FastCGI process manager included in modern versions of PHP. Compared to FCGID it provides better process management features and enables the OPCache to be shared between workers.

  • FCGID and SuEXEC are used for legacy apps that need older versions of PHP (i.e. PHP 5.2 or PHP 4)

  1. Install the machinery
    apt-get update
    apt-get install apache2-mpm-event php5-fpm libapache2-mod-fcgid apache2-suexec-custom php5-cgi
    

TODO libapache2-mod-auth-pam is no longer part of the debian distribution,

replace with libapache2-mod-authnz-external pwauth

  1. Enable some convinient Apache modules

    a2enmod suexec
    a2enmod ssl
    #a2enmod auth_pam
    a2enmod proxy_fcgi
    
  2. Configure suexec-custom

    sed -i "s#/var/www#/home#" /etc/apache2/suexec/www-data
    sed -i "s#public_html#webapps#" /etc/apache2/suexec/www-data
    
  3. Create logs directory for virtualhosts

    mkdir -p /var/log/apache2/virtual/
    chown -R www-data:www-data /var/log/apache2
    
  4. Restart Apache

    service apache2 restart
    
  • ExecCGI

    <Directory /home/*/webapps/>
        Options +ExecCGI
    </Directory>
    
  • Permissions <Directory /home/*/webapps> Require all granted

TODO pool per website or pool per user? memory consumption

events.mechanism = epoll

TODO multiple master processes, opcache is held in master, and reload/restart affects all pools
