Apache2 does not start anymore after a2enmod php7

GregorMartinFehrenbach · August 1, 2023, 4:19pm

PHP code does not become executed on html files. If it’s in a PHP file, that will be offered for download but not executed.
Following several posts t tried
a2enmod php7.

But then apach2 does not start anymore.

gwain:~ # a2enmod php7
gwain:~ # service apache2 restart
Job for apache2.service failed because the control process exited with error code.
See "systemctl  status apache2.service" and "journalctl  -xe" for details.

If I disable php7 then apache2 starts again

gwain:~ # a2dismod php7
gwain:~ # service apache2 restart
gwain:~ #

And what shows


systemctl status apache2.service

and


journalctl -xe

We are not sitting behind you (so far).

The answer inbold is fron a bot isn’t it?
Great!

Then why is my PHP module not threadsve?

It is from the standard distribution!

However, it was in the wrong directory.

So i created a symlink,

gwain:~ # ls -l /usr/lib64/apache2-prefork/mod_php7.so
lrwxrwxrwx 1 root root 30 Aug  1 17:31 /usr/lib64/apache2-prefork/mod_php7.so -> /usr/lib64/apache2/mod_php7.so

GregorMartinFehrenbach · August 2, 2023, 5:45am

This is where yast installs it

Kieltux · August 2, 2023, 4:50pm

What it is in /etc/sysconfig/apache2 configured for mpm?

APACHE_MPM="prefork"

or something else?

GregorMartinFehrenbach · August 3, 2023, 1:06pm

gwain:~ # grep APACHE_MPM /etc/sysconfig/apache2
APACHE_MPM=“”

Kieltux · August 3, 2023, 6:20pm

Change

APACHE_MPM=“”

into

APACHE_MPM="prefork"

then restart apache2.

GregorMartinFehrenbach · August 21, 2023, 3:32pm

Sorry, I was on vacation.

I’ve done that but nothing has changed.

GregorMartinFehrenbach · August 21, 2023, 3:38pm

For my early attempts I still have the ling to th PHP7 library in the apache2-prefork directory.
Should I remove that?

GregorMartinFehrenbach · August 21, 2023, 3:45pm

At least PHP documents do open in the Browser now instead of being downloaded.
But still no execution of PHP code.

GregorMartinFehrenbach · September 11, 2023, 9:24am

@Kieltux Any additional hints? As there is still no execution of PHP code

hcvv · September 11, 2023, 10:00am

Please, you seem to use openSUSE15.2. Support stopped on it 2021-12-31. Which means that probably nobody here will will use that anymore and thus can not look in any configuration files or other to compare with what you have with any guarantee of success (and their memory may also be vague of what were the details two to three years ago).

I wonder. You simply start with describing your problem in post #1 above as if you just started using Apache on your 15.2 system. You do not describe that it was already used for a few years before it stopped doing what you expect.

When it is indeed the case that you started this anew on an old 15.2, why not did you first upgrade (or install a fresh) Leap 15.5?
OTOH, when this was running already on your 15.2, why did you not describe what was done/changed before it stopped functioning?

BTW, in both cases, my advice would be to install openSUSE Leap 15.5 and try again. Either it would function from the start, or you can at least ask here to people who use the same as you do.

GregorMartinFehrenbach · September 11, 2023, 2:00pm

Can I upgrade directly to 15.5 or do I have to do all intermediate steps?

hui · September 11, 2023, 3:01pm

Read:
https://en.opensuse.org/SDB:System_upgrade

Do not skip a release when upgrading! Example: do not upgrade from 15.1 to 15.4. Instead, from 15.1 upgrade to 15.2, then to 15.3, and only then from 15.3 upgrade to 15.4.

hcvv · September 11, 2023, 3:24pm

A new install of 15.5 keeping (or reloading) user data maybe quicker.
Applications might also support upgrading their configuration files and data(-bases) only step by step. Thus users must be prepared to remove their desktop (or other programs) configurations and let them become created new by those applications.
