Database Connection Error after Craft setup #6047

Closed michielkempen closed 4 years ago

michielkempen commented 4 years ago

Description

For the past 5 hours, I have been trying to set up a new Craft CMS application, but I keep running into the same Database Connection Error.

My setup is as follows:

Once the PHP container is started, I run the following command to configure Craft:

root@117529a33f7f:/var/www/html# ./craft setup

Generating a security key ... done (Fny5j3e6SeeqBXxz_uZlBkgSDPPN8oP-)

As you can see in the console logs, everything goes well. Craft is able to connect to my database and create all the necessary tables.

However, as soon as the configuration process has finished, whatever I do; visit the dashboard, run a console command, etc. I always get the Database Connection Error shown below.

root@117529a33f7f:/var/www/html# ./craft
Exception 'craft\errors\DbConnectException' with message 'Craft CMS can’t connect to the database with the credentials in config/db.php.'

I tried every single solution that I could think of, but I cannot figure out why Craft is not able to reach the database. In my opinion, it doesn't even make sense, as Craft uses exactly the same credentials as during the installation only seconds ago when everything went well.

Does anyone have an idea what I could be missing here?

@michielkempen Can you try deleting your storage/runtime/cache folder?

michielkempen commented 4 years ago

Thank you very much for the response, @brandonkelly. This solves the problem! 🙏🏼

After so many hours of debugging, I was literally starting to go crazy.

But this is an issue with the framework, right? I don't think I came across any official resource stating that you should remove your cache folder after the installation process.

Nope, it’s a bug that’s already been fixed for the next release (coming tomorrow) – ec201448b318fd32f00d3e31adb8cb9d89b4ea63. Sorry you got bit by it! There was no GitHub issue at the time, so I’ll point the release note to this one.

Craft 3.4.19 is out now with that fix.
