Re: [IBMiOSS] Wrong version of MariaDB is starting

Thanks Kevin,

I did come across Richard's info.  I just can't recall making a bunch of changes to the original scripts in order to launch the executable.

I am going to write my own script to start the new MariaDB server.  I am just mystified as to how the newer instance was ever running yet it had to be since the WP instances were connecting to it...a major "senior moment" I guess....

Pete, the IBM rpms don’t install anything to /usr/local. That’s where Zend used to install (not sure where they do nowadays). Maybe you or someone modified that script on the old box but missed moving that change over? Otherwise I’m not sure how it ever would have worked for you.

You might want to reference Richard Schoen’s guide for the RPM version: https://github.com/richardschoen/howtostuff/blob/master/installmariadbonibmi.md

Subject: [EXTERNAL] Re: [IBMiOSS] Wrong version of MariaDB is starting
OK...it was late last night

It MY bad memory that I was referring to, not bad memory on my IBM
i....sheesh! Context changes everything

I am dealing with a mystery either caused by <bad memory> or a
complete system shutdown and restart....

Here is the issue. I have relocated my IBM i to a new co-lo which
meant it was shut down, traveled across state lines and came up just
fine about 5 days later. It took a while to get all of the firewall
and access established and although the websites hosted on the i are
running, my WordPress sites threw database errors a la "Error
establishing a database connection". I had been starting mariadb from
SSH with this command: /QOpenSys/usr/bin/sh
/usr/local/mariadb/bin/mysql.sh start Which runs just fine. Except
that didn't solve the connection error. So, from SSH I attempted to
log in to Mariadb directly and get "ERROR 2002 (HY000): Can't connect
to local server through socket '/QOpenSys/var/lib/mysql/mysql.sock'
(2)" which is very weird since my SQL tool, Navicat, CAN open the
databases and they appear to be up to date.

So, I checked the DB connections in the WordPress instances and noted
that they were connecting though port 3307. Navicat was connecting
though port 3306. Starting MariaDB with the command above, I see this
in the logs:

2025-05-13 20:53:14 1 [Note] /usr/local/mariadb/bin/mysqld: ready for
connections.
Version: '10.1.21-MariaDB' socket:
'/usr/local/mariadbdata/mariadb.sock' port: 3306 Source distribution

So it seems like all is well, except the port doesn't match what is
configured in the WP instances. It *should* be 3307 and I know I
didn't change it. So I headed over to "Open Source Package
Management" to check to see what was installed. Package manager says
10.6.12-3 is installed, which doesn't match what I see in the logs.
Taking a look at the installed files for the package, I see a
/QOpenSys/var/lib/mariadb/data folder and in that folder are the
folders containing my DB files.

So, finally, the question: Since I only recall using the mysql start
command above, how was the "other" instance of MariaDB running and how
do I find out how to start it? I remember upgrading MariaDB but I
don't recall running any command to start that instance, but I have
slept many nights since that upgrade....
