(I’ve tried adding those parameters in /usr/share/nextcloud/.user.ini with the same result)

Add lines to /usr/share/nextcloud/config/config.php :

'memcache.local' => '\OC\Memcache\APCu',

The issue I am facing:

I get the following warnings:

No memory cache has been configured. To enhance your performance please configure a memcache if available. Further information can be found in our documentation.
The PHP Opcache is not properly configured.

The output of my Nextcloud log in Admin > Logging:

Please could you help me?

Thanks in advance!

So basically you have two seperate errors:

OPCache settings are not applied.
APCu is not active for Nextcloud

1. OPCache

I am no php_fpm user, but by chance I was just dealing with this:

Inside php-fpm.d/www.conf you need to set these values similar to the others with php_value/php_admin_value. I guess php_admin_value would work for all of them, for some of them it is necessary: http://php.net/manual/en/opcache.configuration.php (the ones with PHP_INI_SYSTEM) =>

php_value[opcache.enable] = 1
php_admin_value[opcache.enable_cli] = 1
php_admin_value[opcache.interned_strings_buffer] = 8
php_admin_value[opcache.max_accelerated_files] = 10000
php_admin_value[opcache.memory_consumption] = 128
php_admin_value[opcache.save_comments] = 1
php_value[opcache.revalidate_freq] = 1

should work.

Otherwise inside .user.ini you can just set the values listet as PHP_INI_ALL (link above). There they need to be set without this php_value stuff.

The traditional way would still be to set the values inside your php.ini/php.d configuration files, in this case preferred the sub file that will be only used, of the opcache module is active: /etc/opt/rh/rh-php56/php.d/XX-opcache.ini (seems to be the location in your case?)

2. APCu

I am little confused that in your case apache and php config files seem to be in one place? I am not sure which one is used in which case etc. But actually as php apcu module is active, apc.enabled=1 should be set as default: http://php.net/manual/en/apc.configuration.php
You could try to set it inside www.conf via php_admin_value[apc.enabled] = 1 as well.

Otherwise my config.php looks like this:
'memcache.local' => '\\OC\\Memcache\\APCu',
But the double backslash was set automatically and single should also work, if I remember well.
