Some solutions to errors on a Synology NAS installation of Nextcloud

Some solutions to various issues which occur when updating/installing a standard installation of Nextcloud on a Synology NAS. All entered in an ssh terminal after issuing sudo -i:

To update missing indexes enter this command, substituting your php.id in place of my semi-hidden one:

sudo -u http /usr/local/bin/php70 -c /var/packages/WebStation/etc/php_profile/9f1e642a-0d20-4664-8934-cxxxxxxxxxe/conf.d/user_settings.ini -f /volume1/web/nextcloud/occ db:add-missing-indices

sudo -u http /usr/local/bin/php70 -c /var/packages/WebStation/etc/php_profile/9f1e642a-0d20-4664-8934-cxxxxxxxxxee/conf.d/user_settings.ini -f /volume1/web/nextcloud/occ db:convert-filecache-bigint

The php profile id is unique to each installation

To update Strict-Transport-Security:

echo ‘add_header Strict-Transport-Security “max-age=31536000; includeSubDomains” always;’ > /etc/nginx/conf.d/http.hsts.conf

To update caching:

edit /volume1/web/nextcloud/config/config.php and add:
'memcache.local' => '\OC\Memcache\APCu',

To solve ocs and ocm provider errors:

ln -s /var/services/web/nextcloud/ocm-provider/ /var/services/web
ln -s /var/services/web/nextcloud/ocs-provider/ /var/services/web

The last solution took me hours and hours to solve, but was so simple! I had been trying to link using /volume1/web but for some reason it required the ‘real’ location of /var/services/web

Hope this helps someone!

Great information.

The line to be added to update cacheing contains smart quotes and will give a server error when cut/pasted. The correct content is:

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

To get the right php profile I use a /usr/local/bin/occ script as follows:

#!/bin/sh
cd /var/services/web/nextcloud
sudo -u http \
  /usr/local/bin/php70 -c /usr/syno/etc/packages/WebStation/php_profile/94dd65f5-1908-4982-bb5c-df064638a869/conf.d/user_settings.ini \
  occ ${1+"$@"}

I also have a spksrc branch to build a nextcloud package for easy install.

Thank you sciurius. I have edited my post to correct the smart quotes in case someone doesn’t read this thread any further.

What is a spksrc branch?

spksrc is the build environment of the Synology Community, where community packages are built.

This seems to cause problems when nginx is restarted.
“DSM cannot start up normally because it ran into a problem. Please contact the Synology support team for help.”

I run Nextcloud as a virtual host in WebStation. Checking HSTS in the config works.

I’ve not had this problem - since I incorporated this fix I have restarted nginx manually several times for various reasons and have rebooted my DS a few times too. Not once has it complained. I installed NextCloud directly, no virtual host or anything like that. If you copied and pasted the fix double check that the correct quotes have survived me posting and you copying - I know this has caused problems in the past.

Lol! Just re-red the thread and it was you who commented about the quotes in another fix. Maybe it’s the issue for this one too.

Tried again, and this time it works. :face_with_raised_eyebrow:
Probably a typo.

What happens: normally nginx runs as

/usr/bin/nginx -g "pid /run/nginx.pid; daemon on; master_process on;"

With an error in /etc/nginx/conf.d/http.hsts.conf this becomes:

/usr/bin/nginx -c /etc.defaults/nginx/nginx.conf.default -g "pid /run/nginx.pid; daemon on; master_process on;"

Don’t know why, but now we know… :grin:

Hello

I am new to the matter. How can I find out the php.id? maybe others have the same question.
