Hi, I installed PHP 7.4 from remi repo. This was an old install and I do not remember how I achieved my current configuration.

There was no problem so far, but recently I encountered my wordpress site unable to open some pages because of mbstring extensions not “installed”

php -m shows these result

but opening able.php with this code:

<?php
 $dom = extension_loaded( 'dom');
 $gd = extension_loaded( 'gd');
 $pdo = extension_loaded( 'pdo');
 $mbstring = extension_loaded( 'mbstring');
 $imagick = extension_loaded( 'imagick');

 echo "mbstring: ", extension_loaded('mbstring') ? 'OK' : 'MISSING', '<br>';
 echo "imagick: ", extension_loaded('imagick') ? 'OK' : 'MISSING', '<br>';
?>

shows

Hello Bogus Drupal, from Tommy the Geek

GD: OK
dom: OK
PDO: OK
zip: OK
mbstring: MISSING
imagick: MISSING

what can I do to enable php74 mbstring and imagick?

If you add to your able.php file the following, what does it output:

echo 'Current PHP version: ' . phpversion();

technicalw · March 15, 2022, 3:09am

update on able.php

<?php
 $dom = extension_loaded( 'dom');
 $gd = extension_loaded( 'gd');
 $pdo = extension_loaded( 'pdo');
 $mbstring = extension_loaded( 'mbstring');
 $imagick = extension_loaded( 'imagick');
 echo '<p>Hello Bogus Drupal, from Tommy the Geek</p>';
 echo "GD: ", extension_loaded('gd') ? 'OK' : 'MISSING', '<br>';
 echo "dom: ", extension_loaded('dom') ? 'OK' : 'MISSING', '<br>';
 echo "PDO: ", extension_loaded('pdo') ? 'OK' : 'MISSING', '<br>';
 echo "zip: ", extension_loaded('zip') ? 'OK' : 'MISSING', '<br>';
 echo "mbstring: ", extension_loaded('mbstring') ? 'OK' : 'MISSING', '<br>';
 echo "imagick: ", extension_loaded('imagick') ? 'OK' : 'MISSING', '<br>';
 echo 'Current PHP version: ' . phpversion();
?>

and the result is:

Hello Bogus Drupal, from Tommy the Geek

GD: OK
dom: OK

zip: OK
mbstring: MISSING
imagick: MISSING

If you’re using PHP FPM mode you would need to restart php74-php-fpm service, otherwise restart Apache/Nginx.

technicalw · March 15, 2022, 8:51am

it is running fcgid, I have restarted both nginx and fpm, same result. Is there a config on php.ini or user.ini that may prevent mbstring and imagick to be enabled?

Ilia · March 15, 2022, 8:58am

Oh, when running PHP in FCGID mode with Nginx you should restart corresponding Nginx PHP FastCGI server service. Check System ⇾ Bootup and Shutdown module.

technicalw · March 15, 2022, 10:17am

wonderful! After restarting the corresponding nginx php fastcgi server, mbstring is now detected. However imagick is still not detected. Did I miss something?

What makes you think it’s not detected? Try creating a small phpinfo.php file calling phpinfo(); function and running. What does it output in regards of imagick?

technicalw · March 16, 2022, 7:25am

phpinfo.php show imagick 1 occurence in this section. No other imagick occurences in phpinfo result.

Perhaps your extension isn’t loaded in /etc/opt/remi/php74/php.d/40-imagick.ini file?

It should have uncommented extension= directive referring the module’s binary, which looks something like this:

; configuration for php imagick module
extension=imagick.so

technicalw · March 17, 2022, 3:10am

it is already uncommented

; Enable imagick extension module
extension = imagick.so

; Documentation: http://php.net/imagick

; Don't check builtime and runtime versions of ImageMagick
imagick.skip_version_check=1

; Fixes a drawing bug with locales that use ',' as float separators.
;imagick.locale_fix=0

; Used to enable the image progress monitor.
;imagick.progress_monitor=0

; multi-thread management

; to allow null images

Please ensure the file actually exists in the correct path, also check the webserver log for any errors.

technicalw · March 17, 2022, 8:53am

Yes, this is the case.
Some logs here:

PHP Startup: Unable to load dynamic library 'imagick.so' (tried: /usr/lib64/php/modules/imagick.so (/usr/lib64/php/modules/imagick.so: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/imagick.so.so (/usr/lib64/php/modules/imagick.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

ls /usr/lib64/php/modules/ does not show imagick.so

How can I create the file?
dnf reinstall php74-php-imagick does not create imagick.so in here.

Ilia · March 17, 2022, 10:53pm

This is not something I can reproduce.

What is the output of:

dnf reinstall php*imag*

Also, how does virtual-server.name - Server Configuration ⇾ PHP Options page look like? Do you have a screenshot?

I must say that it works just fine for me on AlmaLinux with PHP 7.4 from remi.

What have happened to the default PHP 7.2 pre-installed by default?

What is the output of:

dnf list | grep php | grep @

It looks that you have deleted basic default packages.

Did I delete some default packages? As far as I remember, I do not delete any packages, but my memory may not serve me right.

AFAIK, I just try to install redis, varnish, and remi for installing other php version, wpcli and telegraf.
Caching software are not used yet, just installed and let service running without any method from wordpress to interact with those softwares. Telegraf is currently disabled due to influxdb server on another vps not stable enough to receive datas from multiple server.

It seems that all issues in your case are caused by installing mod_php which you shouldn’t do!

Start from removing these packages:

dnf remove php php74

Then restart Nginx and re-check config. Afterwards, go to PHP Options page and change execution mode to FPM.

Thank you! This is solving my issue, and likely issues on other server that I installed all with dnf install php74 which in the end prevent me to use PHP FPM.

PHP mbstring and imagick is now detected.
