Summary of the issue you are facing:

I am receiving an error message in my admin page in my NextCloud Instance that says the following:

PHP opcache

The PHP OPcache module is not properly configured. The OPcache buffer is nearly full. To assure that all scripts can be hold in cache, it is recommended to apply “opcache.memory_consumption” to your PHP configuration with a value higher than “256”..

This is a brand new install. I haven’t even used it yet. I only created one document as a test. I don’t understand why I am getting this error. I installed it on my brand new Ugreen Nas 6800 Pro. 64G of memory, 10 core.

I installed it using Portainer. This is the Docker Compose File that I used:

services:
nextcloud-aio-mastercontainer:
image: nextcloud/all-in-one:latest
init: true
restart: always
container_name: nextcloud-aio-mastercontainer
volumes:

  • nextcloud_aio_mastercontainer:/mnt/docker-aio-config
  • /var/run/docker.sock:/var/run/docker.sock:ro
    network_mode: bridge
    ports:
  • 8089:8080
    environment:
  • APACHE_PORT=11000
  • APACHE_IP_BINDING=0.0.0.0
  • NEXTCLOUD_UPLOAD_LIMIT=10G
  • NEXTCLOUD_MEMORY_LIMIT=4096M
  • COLLABORA_SECCOMP_DISABLED=true
  • NEXTCLOUD_ENABLE_DRI_DEVICE=true
  • NEXTCLOUD_MOUNT=/volume2/
  • NEXTCLOUD_DATADIR=/volume2/docker/nextcloudaio/data
  • SKIP_DOMAIN_VALIDATION=true

volumes:
nextcloud_aio_mastercontainer:
name: nextcloud_aio_mastercontainer

The only change that I made to the file is I changed Volume 1 to Volume 2. My Volume 2 is my M.2 SSD. I figured it would be snappier on that.

If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

Tips for increasing the likelihood of a response

  • Use the preformatted text formatting option in the editor for all log entries and configuration output.
  • If screenshots are useful, feel free to include them.
    • If possible, also include key error output in text form so it can be searched for.
  • Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.

Hello, this is my configuration of the OPCACHE module in the php.ini file. And it works without any problems for me.

Please back up your php.ini file and change these values.

opcache.enable=1

opcache.enable_cli=1

opcache.interned_strings_buffer=20

opcache.memory_consumption=128

opcache.max_accelerated_files=10000

opcache.revalidate_freq=1

opcache.save_comments=1

I can’t find the file. It’s a brand new instance that hasn’t been used yest and so I am not worried about backing up anything.

  1. I went to docker and stopped all of the containers
  2. Went into to my shared folders in Docker, opened up the file that says Nextcloud AIO, and opened up every folder that was inside. I found no folder that was titled, php.ini. I had a folder that was labeld, Cache. I opened that folder and there was nothing in it. Blank.

Where can I find that php.ini folder?
