Opcache Settings via NCP

[feutl]

Description
The error message The OPcache interned strings buffer is nearly full. in Nextcloud, starting with NC23, was the reason to dig a little deeper into the problem and I found this thread https://help.nextcloud.com/t/nextcloud-23-02-opcache-interned-strings-buffer/134007

As far as I have understood, with NC23 it is capable of giving you recommendations for settings to be changed based on the individual usage of the server. In my case the opcache was full therefore the recommendation was to increase opcache.interned_strings_buffer

This was as not a problem for me to do manually, but this setting should be added to the nc-limits in ncp-web / ncp-cli.

@feutl sorry for asking but how to set the opcache value? I have the exact same "problem". I'm using docker and I see that the path /etc/php/8.1/fpm/conf.d/10-opcache.ini leads me to the target but I really do not want to map the different values of the config with a volume. Seems very dirty to me.

Honestly, I have just changed my opcache.ini as recommended by NC Even did that for the latest upgrade with PHP 8.1, NCP 15 and NC 24.

It would be nice to have that setting inside NCP, but as for now, it needs to be done manually.

@feutl okay I understood but how did you do that 😆

Like I mentioned? Or how?

[feutl]

@saschabrockel I have no docker setup, so I just changed the values in the file according to the recommendations from NC itself. no volumes needed.

Hi, I've also modified /etc/php/8.1/fpm/conf.d/10-opcache.ini with only these: zend_extension=opcache.so opcache.interned_strings_buffer=16 opcache.revalidate_freq=60 opcache.file_cache=/media/DATAcloud/ncdata/data/.opcache; like so: https://github.com/nextcloud/nextcloudpi/pull/1661/files

And enabled these ones directly in /etc/php/8.1/fpm/php.ini opcache.enable=1 opcache.max_accelerated_files=10000 opcache.interned_strings_buffer=16 opcache.memory_consumption=128 opcache.save_comments=1 opcache.revalidate_freq=60

Am i right?

OK, I have migrated to NCP Docker today, and now I am on the same boat. How do I permanently set the opcache for php ?! The php config files are not stored in the mounted volume. I can only find apache and cron there.

For now I changed the /etc/php/8.1/fpm/conf.d/10-opcache.ini file, The new value for my setup to avoid this problem is opcache.interned_strings_buffer=64 after this, I restarted the php service with service php8.1-fpm restart and Nextcloud stopped complaining.

But this is not permanent! @theCalcaholic this would be very important to be integrated into the docker setup, because otherwise the values are not persistent after a docker reboot.
