I have installed mpm_itk using

apt-get install apache2-mpm-itk

But after installing, when I try to enable using

a2enmod mpm_itk 

it says module is not found

At first I was using apache2.4.10, I tried to shift to 2.4.7 but same problem. I am on ubuntu 14.04

Help on how to solve.

  • By any chance do you have mpm_prefork mod installed ?

If mpm_prefork installed then it may cause issues while enabling mpm_itk.

So disable mpm_prefork and then try enabling or try reinstalling mpm_itk.

# a2dismod mpm_prefork
# a2enmod mpm_itk

EDIT: Installation

sudo apt-get install libapache2-mpm-itk

Then try

a2enmod mpm_itk

You have choose proper package to install it seems , observe the below log

Setting up libapache2-mpm-itk (2.4.7-04-1) ...
apache2_invoke: Enable module mpm_itk
root@openstackm1:~# a2enmod mpm_itk
Considering dependency mpm_prefork for mpm_itk:
Considering conflict mpm_event for mpm_prefork:
Considering conflict mpm_worker for mpm_prefork:
Module mpm_prefork already enabled
Module mpm_itk already enabled
  • it didn't work, the apache2 failed to restart, it says: AH00534: apache2: Configuration error: No MPM loaded . It seems mpm_itk is not part of default distribution, when i install manually, it cannot be found in the /etc/apache2/sites-available directory. I don't know where does it go. That is why it kept saying: cannot find module Jan 3, 2017 at 13:50
  • give us complete activity logs. It will help us understanding the issue. Thank you.

  • The problem is not mpm_prefork. The issue is that after installing mpm_itk it goes somewhere else and not in: /etc/apache2/sites-available so no matter how i try to enable it with: a2enmod mpm_itk it never gets found. Now i where did it go after installation. Any idea please! @Ten-Coin Jan 3, 2017 at 13:55
  • This is the output i get this time when i try to edit the installation: 0 upgraded, 0 newly installed, 0 to remove and 72 not upgraded. @Ten-Coin Jan 3, 2017 at 14:03
  • And the problem proceeds Jan 3, 2017 at 14:03
