My YunoHost server
Hardware: Rented VPS (OVH)
YunoHost version: 3.6.4.6
I have access to my server : Through SSH and webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : yes, I added a local shared folder to Nextcloud in order to share music to an Airsonic instance
Description of my issue
When I try to upload certain files to my Nextcloud instance (for example, ones with emoji), the upload fails due to lack of support for the encoding. Browsing around I found out that the server must be manually configured to support UTF8mb4 specifically, and Nextcloud’s website has a list of steps to follow in order to configure MySQL to support 4-byte UTF8. However, since Yunohost is the one managing the databases, I cannot actually log into MySQL. Trying to run the application as root or admin outputs an error message stating that the user doesn’t have permissions:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
The next best thing I found was this post on the forum which recommended adding a few parameters to the my.cnf
configuration file, which didn’t work either. When running mysql
the error message was now as follows:
mysql: unknown variable 'innodb_large_prefix=ON'
And when attempting to run the Nextcloud occ
script as recommended on the link above, the error message is:
$ sudo -u nextcloud php occ db:convert-mysql-charset
The database is not properly setup to use the charset utf8mb4.
For more information please read the documentation at https://docs.nextcloud.com/server/15/go.php?to=admin-mysql-utf8mb4
So then, what would be the proper way to enable UTF8mb4 on my server? Does it require manually logging in as whatever user was assigned as the MySQL administrator and if so, how do I obtain the auto-generated password?
