MPM-Event für Apache einrichten

1. Bearbeite die entsprechende Datei via SSH

mcedit /etc/httpd/conf.modules.d/00-mpm.conf

2. Kommentiere folgenden Eintrag durch Setzen einer Raute "#" aus und deaktiviere somit den Modus prefork

LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

3. Aktiviere durch Entfernen der Raute vor diesem Eintrag den Modus "worker"

LoadModule mpm_worker_module modules/mod_mpm_worker.so

4. Ergänze die Folgenden Blöcke im unteren Bereich

<IfModule mpm_worker_module>
        StartServers                    8
        MinSpareThreads                 50
        MaxSpareThreads                 100
        ThreadLimit                     64
        ThreadsPerChild                 64
        MaxRequestWorkers               384
        MaxConnectionsPerChild          10000
        ServerLimit                     6
        GracefulShutdownTimeout         5
</IfModule> 

<IfModule mod_deflate.c>
        <IfModule mod_filter.c>
                # these are known to be safe with MSIE 6
                AddOutputFilterByType DEFLATE text/html text/plain text/xml

                # everything else may cause problems with MSIE 6
                AddOutputFilterByType DEFLATE text/css
                AddOutputFilterByType DEFLATE application/x-javascript application/javascript application/ecmascript
                AddOutputFilterByType DEFLATE application/rss+xml
                AddOutputFilterByType DEFLATE application/xml
        </IfModule>
</IfModule> 

Hinterher sieht die Datei dann so aus
