neither prefork nor worker settings are found in /etc/apache2/apache2.conf - why?

I've just installed Apache 2.4.7 (Ubuntu) on my Ubuntu 14.04 LTS system and can't see neither prefork nor worker settings in the /etc/apache2/apache2.conf. They are also not defined for default virtual host. Should I set them myself in apache2.conf like this?

<IfModule mpm_prefork_module>
    StartServers 2
    MinSpareServers 2
    MaxSpareServers 5
    MaxClients 200 #must be customized
    ServerLimit 200 #must be customized
    MaxRequestsPerChild 100
</IfModule>

    Ubuntu 14 organizes all the module-specific configs in separate files under /etc/apache2/mods-available/, so the MPM prefork stuff is now located in /etc/apache2/mods-available/mpm_prefork.conf

  2. Have you looked for these settings within /etc/apache2/conf.d/? It's likely that these settings are kept in separate included files to aid with packaging.

    Yes, you can place them in apache2.conf (though do look for them in other files in conf.d/ as mentioned above).

    Your MaxRequestsPerChild seems very low - this can be in the thousands.

    If you are running mod_php your MaxClients should be lowered significantly, unless you have many gigs of RAM.
