apache2 won't start

Pedroski · 09-26-2022, 02:39 AM

I just did a dist upgrade, from Ubuntu 20.04 to 22.04.

Now apache2 won't start, I can't test my own, home-made webpages on my localhost! Could you please give me some tips?

line 146 of apache2.conf is: IncludeOptional mods-enabled/*.load

php is installed and the newest version.

There are some syntax errors in the configuration file. The line numbers in question are given in the error message which you have posted. If the files themselves have not changed, then check to ensure that the relevant Apache2 modules are installed and active.

The utilities apache2ctl configtest and a2enmod or a2query can possibly help.

Thanks!

I ran a2enmod,

Which module(s) do you want to enable (wildcards ok)?
php8.1
Considering dependency mpm_prefork for php8.1:
Considering conflict mpm_event for mpm_prefork:
Considering conflict mpm_worker for mpm_prefork:
Module mpm_prefork already enabled
Considering conflict php5 for php8.1:
Module php8.1 already enabled
pedro@pedro-512ssd:~$

I have a sym link: /etc/apache2/mods-enabled/php8.1.load which links to ../mods-available/php8.1.load and there is:

Quote:

# Conflicts: php5
# Depends: mpm_prefork
LoadModule php_module /usr/lib/apache2/modules/libphp8.1.so

Now I need to tell apache2 to load php8.1.so not php7.4.so, I think！？？！

Where do I tell apache2 that?? Which conf?

Pedroski · 09-26-2022, 04:16 AM

Got it working!

I went to /etc/apache2/mods-enabled and renamed the php7.4.load

Quote:

sudo mv php7.4.load php7.4.load.old

Then I had to set the permissions again: (is there some way to avoid having to do this??)

Quote:

sudo chown -R pedro /var/www/
sudo chgrp -R www-data /var/www/
sudo chmod -R 770 /var/www/
sudo chmod g+s /var/www/

Now my localhost opens, but I need a new version of phpMyAdmin, it won't work with php 8.1
