The issue you are facing:
NextCloud working fine for years on a Digital Ocean droplet with MySQL running on the same droplet. I’m migrating the MySQL database to a Digital Ocean Managed Database. When I configure NextCloud to use the Managed Database, the database connection times out.
As soon as I set the configuration back to the local MySQL server, it works fine again.
I can access the Managed Database from the droplet’s command line mysql client and from a PHP script using PDO_MYSQL running in another vhost on the same droplet.
I don’t have a lot of experience with DO Managed Databases, but it sure seems like this must be something simple. Got any troubleshooting suggestions?
Thanks!
Is this the first time you’ve seen this error? Yes
Steps to replicate it:
- Starting from my working NextCloud installation.
- Migrate the database:
sudo -u www-data php7.3 occ maintenance:mode --on
mysqldump --no-tablespaces --default-character-set=utf8mb4 -u nextcloud -p'...' nextcloud | mysql -u sbw_nextcloud -p'...' -h db-mysql-...-0.a.db.ondigitalocean.com -P 25060 -D sbw_nextcloud
- Reconfigure as follows:
sudo -u www-data php7.3 occ config:import ~/nextclouddbmanaged.json
Here’s that JSON file:
{
"system": {
"dbname": "sbw_nextcloud",
"dbhost": "db-mysql-...-0.a.db.ondigitalocean.com",
"dbport": "25060",
"dbuser": "sbw_nextcloud",
"dbpassword": "..."
}
}
- Note the web site is unresponsive, and this command (for example) throws an exception:
sudo -u www-data php7.3 occ user:list
Here’s the exception:
Doctrine\DBAL\DBALException: Failed to connect to the database: An exception occurred in driver: SQLSTATE[HY000] [2002] Connection timed out in /.../lib/private/DB/Connection.php:64
I’ve also tried editing config.php directly. Same result: An occ command fails in the same way, and the web site is unresponsive.
After I manually change config.php back to the local MySQL server, all is back to normal.
