Error! MariaDB is not running

Troubleshooting
1

Error! MariaDB is not running on your system - database list could not be retrieved.

MariaDB error messageThe full MariaDB error message was : DBI connect failed : Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (111) ?

Failed to start database : Redirecting to /bin/systemctl start mariadb.service Job for mariadb.service failed because the control process exited with error code. See “systemctl status mariadb.service” and “journalctl -xe” for details.

And what do systemctl status mariadb.service and journalctl -xe say about this?
Use preformatted text for the console output.

Any specific reason to ignore the troubleshooting template @dub ?

At least it would give some information on your system.

This is not a DietPi system?

7

i use webmin

8

Looks like another instance of mariaDB is already running?
I already found similiar threads in the official webmin forum:
https://forum.virtualmin.com/t/error-mariadb-is-not-running-on-your-system-database-list-could-not-be-retrieved/115395

This doesn’t answer my quest in any sense.

We are within a DietPi forum supporting DietPi operating system. We don’t maintain Webmin. It’s just an app you can install on our system.

From what I see, you are running CentOS 7.9, which seems to be outdated and going out of support shortly End dates are coming for CentOS Stream 8 and CentOS Linux 7 – Blog.CentOS.org

Same for kernel version 3.10, which is as well years old.

Next one MariaDB 5.5.68. Current version is 11.3

Anyway you can reboot your system and check database logs

journalctl -u mariadb
