Apache – How to Display Configuration

The trick is that you need to rename the action and alias too so they are not 'redefinitions', so for my 'www' pool, my vhost config looks like this:

<IfModule mod_fastcgi.c>
    <FilesMatch \.php$>
        SetHandler php-script
    </FilesMatch>
    Action php-script /php5-www.fcgi virtual
    Alias /php5-www.fcgi /var/fastcgi/php5-www.fcgi
    FastCGIExternalServer /var/fastcgi/php5-www.fcgi -socket /var/run/php5-fpm-www.sock
    <Directory "/var/fastcgi">
        Order allow,deny
        <Files "php5-www.fcgi">
            Order deny,allow
            Deny from all
            Allow from env=REDIRECT_STATUS
        </Files>
    </Directory>
</IfModule>

And for SSL on the same pool:

<IfModule mod_fastcgi.c>
    <FilesMatch \.php$>
        SetHandler php-script
    </FilesMatch>
    Action php-script /php5-www-ssl.fcgi virtual
    Alias /php5-www-ssl.fcgi /var/fastcgi/php5-www-ssl.fcgi
    FastCGIExternalServer /var/fastcgi/php5-www-ssl.fcgi -socket /var/run/php5-fpm-www.sock
    <Directory "/var/fastcgi">
        Order allow,deny
        <Files "php5-www-ssl.fcgi">
            Order deny,allow
            Deny from all
            Allow from env=REDIRECT_STATUS
        </Files>
    </Directory>
</IfModule>

So they're using different names, but pointing at the same socket.

You can set mpm_module to false, to explicitly declare the prefork-class with custom parameters afterwards.

class {
  'apache':
    mpm_module      => false,
}
class {
  'apache::mod::prefork':
    startservers    => "5",
    minspareservers => "3",
    maxspareservers => "3",
    serverlimit     => "64",
    maxclients      => "64",
}
