ERROR 2002 (HY000): Can't connect to local server through socket '/var/lib/mysql/mysql.sock' (2)

I am using a licensed DirectAdmin with AlmaLinux and encountered an error when rebuilding mariadb:

```
ERROR 2002 (HY000): Can't connect to local server through socket '/var/lib/mysql/mysql.sock' (2)
```

Here are the commands that I ran:

```
cd /usr/local/directadmin/custombuild
./build update
./build set mysql_backup yes
./build set "mariadb" 10.3
./build set mysql_inst "mariadb"
./build "mariadb"

```

Hello,

Downgrading MariaDB is not supported. The only reliable way to downgrade is to restore from a full backup made before upgrading, and start the old version of MariaDB.

Downgrading between Major Versions of MariaDB

Downgrading MariaDB is not supported.

You might reinstall MariaDB 10.6, or recover your installation of 10.3 from backups.

I did an upgrade to 10.6. But doesn't seem to work. Please support me


cd /usr/local/directadmin/custombuild
./build update
./build set mariadb 10.6
./build set mysql_inst mariadb
./build set mysql_backup yes
./build mariadb

You might use official docs for it: https://docs.directadmin.com/other-...adb-mysql/general.html#how-to-reinstall-mysql

There is no sense to copy-paste all the instructions.
