Flarum encountered a boot error (Doctrine\DBAL\Driver\PDOException)

MikeJones

So I upgraded my flarum server to the latest ubuntu and also upgraded to php 7.4

When I tried to open my flarum after this I got this error:

Flarum encountered a boot error (Doctrine\DBAL\Driver\PDOException)
SQLSTATE[HY000] [2002] No such file or directory
thrown in /var/www/seekadventure.net/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php on line 31

Could mysql not be using my upgraded PHP? If so not sure where to start to fix that.

MikeJones I believe in the past people have resolved that issue by replacing the MySQL server address from localhost to 127.0.0.1 in config.php

MikeJones

clarkwinkelmann If I change the config, do I need to restart something before trying to navigate to the page again?

I tried restarting nginx after the edit but it didnt change anything. Still the same error.

MikeJones the changes to config.php should apply immediately.

I'm not sure what it could be if that's not the database address.

I now have a hunch that mysql may not be running since my server upgraded:

ubuntu@ip-172-31-66-31:~$ service mysql status
mysql.service
     Loaded: masked (Reason: Unit mysql.service is masked.)
     Active: inactive (dead)

I then tried running

sudo /etc/init.d/mysql start
but I get the same status of iactive (dead)

I also just ran netstat -tlnp

and I didnt see mysql running

SO I think I found my issue after some more digging on stack overflow, but still doing some research on how to fix.

I think my php 7.4 is not pointing to the mysql socket. in my php.ini file I saw this:

[Pdo_mysql]
; Default socket name for local MySQL connects.  If empty, uses the built-in
; MySQL defaults.
pdo_mysql.default_socket=

Seems off that pdo_mysql.default_socket= doesnt equal anything....

I will keep you all posted if I find the fix just in case someone else has this issue while upgrading a server.

This is goign to sound really dumb, but I just did a sudo apt install mysql-server and now it seems to be working! Going to run through everything again and see how it goes :-)

It happens went your host MySQL rss2 server is down, mostly is overloaded or completely out of reach. It can be overloaded when there is a backup running (shared hosting accounts)

just ignore the error

I already update the local XAMPP to latest php 8, but get the same error. I believe something need to edit with mysqli, can some one help me?
