PHP Startup: Unable to load dynamic library 'redis.so'

[SPDTeam]

Hi all

I recently was trying out Redis and after the experiment I uninstalled it. Or so I thought.

I've just noticed several errors being recorded at the Account (website) level, in the error_log file.

PHP Warning:  PHP Startup: Unable to load dynamic library 'redis.so' (tried: /opt/cpanel/ea-php74/root/usr/lib64/php/modules/redis.so (/opt/cpanel/ea-php74/root/usr/lib64/php/modules/redis.so: cannot open shared object file: No such file or directory), /opt/cpanel/ea-php74/root/usr/lib64/php/modules/redis.so.so (/opt/cpanel/ea-php74/root/usr/lib64/php/modules/redis.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

I've checked for references to Redis in the PHP.ini (WHM >> MultiPHP INI Editor) but cannot see anything specific to Redis.

I've missed a step somewhere.

Any suggestions?

Hey there! Can you try running the following command to see if that shows you an entry for Redis directly in the configuration?

grep -R redis /opt/cpanel/ea-php74/root/etc/php.ini

If not, you may want to try a more general search of those areas with something like this:

[CODE]grep -Ri redis /opt/cpanel/ea-php*/root/etc/php.ini

[/CODE]

Thanks, PRex

I eventually found the culprit.

It was in

/opt/cpanel/ea-php74/root/etc/php.d/redis.ini

line: extension=redis.so.

For now, I've commented the line out. Hopefully, that will stop the errors.

What would be the safe way to uninstall Redis and the EasyApache4 PHP extension? Assuming I don't just remove the redis.ini...

I'm glad that command helped to track it down.

Since Redis isn't something we support on our end, we don't have a recommended install or uninstall option. You may have seen this thread where this was discussed:

Recommended way to install redis on WHM (CentOS 7)

What is the recommended way to install redis? Is it yum install php-pecl-redis as I can see here: phpredis/phpredis [I can also see a pecl-redis package at WHM > Software > Module Installers > PHP PECL > redis search > redis (5.2.2) ] Or something like this as I can see here: How To Install...

forums.cpanel.net

but none of those steps use cPanel tools as it's all done through the Yum and RPM system.

Thanks, will do.
