I don't understand what's wrong with the socket. Every other application including mysqld has MySQL/MariaDB working perfectly with that same socket. It's only failing during upgrades like these.
I've looked through past posts on this forum and tried suggestions, but haven't found a solution yet.

Hello,

Try and put the socket definition under every section of my.cnf file:

Code: 
socket                  = /usr/local/mysql/data/mysql.sock

One of our servers with Debian has this:

Code: 
[mysqld_safe]
port                           = 3306
socket                         = /usr/local/mysql/data/mysql.sock

Seems something is really wrong with your setup. First you had issues with PHP-FPM sockets, and now you have an issue with MySQL. Did you by any chance change recursively permissions on root and/or parent directories?

Code: 
ls -la /usr/local/mysql/data/mysql.sock
ls -lda /usr/local/mysql/data/
ls -lda /usr/local/mysql/
ls -lda /usr/local/
ls -lda /usr/
ls -lda /
?

Try to simlink /etc/my.cnf to /etc/mysql/my.cnf

Does OS in Directadmin license match the version you really run? I mean do you really have a directadmin license for Debian 9?

Do you have a native kernel? Or hardened from a 3rd party?

If nothing helps, you might need to contact a directadmin support for a free help (they might login to your server and check what is wrong)? Or feel free to hire me for this job.
 
What are you running at the moment? MySQL or MariaDB.
Are you still on custombuild 1?

I think I have this issue with MySQL/MariaDB since I upgraded to Debian 8 last year, I used to think the upgrade sworked because the version number gets increased even with failed upgrades. I haven't touched the permission of those directories.
Code: 
~# ls -lda /usr/local/mysql/data/mysql.sock
srwxrwxrwx 1 mysql mysql 0 Jan 12 22:46 /usr/local/mysql/data/mysql.sock

~# ls -lda /usr/local/mysql/data/
drwx--x--x 11 mysql mysql 4096 Jan 12 22:56 /usr/local/mysql/data/

~# ls -lda /usr/local/mysql/

~# ls -lda /usr/local/

I've tried this, but the result is the same.

Click to expand...
Yes, the license is set on Debian 9 64-bit. I even recompiled DirectAdmin to be sure it matches.

zEitEr said:

It runs on the latest native kernel provided by apt-get.
Code: 
~# uname -rv
4.9.0-5-amd64 #1 SMP Debian 4.9.65-3+deb9u2 (2018-01-04)

Good to know, though I hope to learn from this :)

I'm running MariaDB 5.5 on Custombuild2.

Then to update you need to use this:

Code: 
cd /usr/local/directadmin/custombuild
./build set mariadb 5.5
./build set mysql_inst mariadb
./build set mysql_backup yes
./build update
./build mariadb
 
Well permissions look more or less the same as I have here. The difference is only here:

Code: 
drwxr-xr-x 81 mysql mysql 4096 Dec 27 05:08 /usr/local/mysql/data/

MySQL logs do not show errors.

If upgrade fails, I'd try and do a completely new installation of MariaDB on the server. Check https://help.directadmin.com/ for the instructions on how to re-install MySQL/MariaDB.
 
I tried Awd's suggestion to try ./build mariadb instead (I thought it'd just run ./build mysql in the background) and the actual first time it didn't gave the socket error, instead it said to use --force to force an upgrade (which should be the default setting according to the DA documentation). Every other attempt after that, including trying /usr/local/mysql/bin/mysql_upgrade --force --defaults-extra-file=/usr/local/directadmin/conf/my.cnf, gave the socket error again.

Changing the permissions of /usr/local/mysql/data/ to 755 had no effect either.

I'll be trying a new installation of MariaDB later today :)
 
An update about my situation for whoever googles this topic.

Didn't do a new installation, I couldn't afford any downtime due to a new business contract. But the issue solved itself. I didn't upgrade MariaDB for months, I didn't change any related config file. Keeping my Debian installment up-to-date seemed to have done the trick.
 
The problem returned with the latest 5.5.64 update for MariaDB. I changed nothing to my configuration since the successful 5.5.63 update two weeks ago. I did update from Debian 9.8 to Debian 9.9 this week.
