I have installed MariaDB locally on my Mac using Homebrew. Everything works fine until I restart my computer. After a computer restart I cannot access my local database server anymore. The files in /opt/homebrew/var/mysql/are still there, but something seems to be broken and I have no idea what. The only solution I could find is to completely re-install MariaDB and set up all databases again which is obviously highly annoying.
Does anyone have any clues on the reason for this break? I did think about stopping MariaDB before shutting down the computer, but I forget that everytime. Also, it hasn’t always been this way. It’s a fairly recent behaviour.
[EDIT 1]
Here’s the error message when connecting to MySQL after a computer restart:
mysql -u root -p
Enter password:
ERROR 2002 (HY000): Can't connect to local server through socket '/tmp/mysql.sock'
[EDIT 2]
I now tested to stop MariaDB before shutting down the computer – and the problem even occurred immediately after restarting MariaDB, before shutting down the computer. nabim sademba’s comments (thank you!) actually led me to the following output after rebooting the computer – even brew services start mariadb apparently does not start it:
% brew services list
Name Status User File
httpd started myusername ~/Library/LaunchAgents/homebrew.mxcl.httpd.plist
mariadb none root
php started myusername ~/Library/LaunchAgents/homebrew.mxcl.php.plist
php@7.4 none

php@8.1 none
php@8.2 none
% brew services start mariadb
==> Successfully started `mariadb` (label: homebrew.mxcl.mariadb)

And here’s /opt/homebrew/etc/my.cnf (after the failed restart of MariaDB)
#
# This group is read both by the client and the server
# use it for options that affect everything
#
[client-server]
#
# include *.cnf from the config directory

!includedir /opt/homebrew/etc/my.cnf.d

And here’s some log data from /opt/homebrew/var/mysql/mycomputer.local.err with error messages about InnoDB (read in a different post to check that)

The current version of MariaDB delivered by homebrew has a bug which corrupts the database on shutdown. It seems there is already a new version available, but not in homebrew yet.
