OTRS Appliance 4.0.8 - MPM model not ready

[Eric26]

Hello,

I was using OTRS Appliance 4.0.3 and, after the upgrade to version 4.0.8, the services center shows me MPM Model in red color with this message : OTRS requires apache to be run with the 'prefork' MPM model.

I tryed to enable prefork model instead of worker with a2enmod and a2dismod in Shell but mods can't be found. Searching mdm* on all appliance does not find anything.

Is MPM model important for OTRS work ?
If yes, could someone help me to solve this issue, please?

Regards,
Eric

I strongly recommend to move away from the OTRS Appliance. You'll find a lot of post in the forum where it's describe as a test platform. By moving away from it you will also be able to upgrade to the latest patchlevel or major release of OTRS.

Back to your question: I'm not sure if the Apache mpm module is included, what's the output of

Code: Select all

apache2 -l

and

Code: Select all

apache2 -t -D DUMP_MODULES

Thanks for quick reply.

I know OTRS Appliance is no more supported over 4.0.8 but my company used it for a long time with many customizations. So it's hard it to change to the latest non-appliance version. We'll change this... one day

Any way, here is the output of apache2 -l :

Compiled in modules:
core.c
mod_log_config.c
worker.c
http_core.c
mod_so.c

apache -t -D DUMP_MODULES returns an error:

bad user name ${APACHE_RUN_USER}

So I used apachectl -M instead it returns:

Syntax OK

Looking in /etc/apache2/mods-available/ there is no prefork module displayed.
