Hi there and thanks for reading.

I'm not usually a system admin, more of a software developer, but was given the task of setting up a new Apache server. I've finally diagnosed the environment variable issues, but am getting a "No MPM loaded" error when I try to start Apache. Did I download the wrong version? I don't think the laptop I'm working has multiprocessors.

Apache/2.4.58 (Ubuntu)

Thanks in advance for the help!

You need to load one of the MPMs. mod_mpm_event or mod_mpm_worker or mod_mpm_prefork.

Code:

ls /etc/apache2/mods-available/mpm*

/etc/apache2/mods-available/mpm_event.conf  /etc/apache2/mods-available/mpm_prefork.conf  /etc/apache2/mods-available/mpm_worker.conf
/etc/apache2/mods-available/mpm_event.load  /etc/apache2/mods-available/mpm_prefork.load  /etc/apache2/mods-available/mpm_worker.load


Code:

a2enmod mpm_worker
