/usr/bin/mysqld_safe: No such file or directory

Had and error :

Feb 23 02:26:07 domain /etc/init.d/mysql[1993]: /etc/init.d/mysql: line 114: /usr/bin/mysqld_safe: No such file or directory .

This happened during a mysql database server restart that failed. service mysql start did not work.
Only mysqld --datadir=/var/lib/mysql --user=mysql --socket=/var/run/mysqld/mysqld.sock did.
The mysqld_safe is truly missing in /usr/bin.

What would you recommend to fix this? Will provisioning fix this issue? Or do I need to do a

sudo apt-get purge mysql-server
sudo apt-get update
sudo apt-get install mysql-server

post backing up all? The former would be better I would say, especially if I can keep my databases on the server though I can back them up…

Also post Spectre patches at DO they recommend some changes. Have these been taking into account for the latest Trellis?

That’s pretty weird…

If you’ve backed everything up I’d try removing those packages:

sudo apt-get purge mariadb-client mariadb-server

Then re-provision your server and re-import the DB after. You could give that a try and if it doesn’t work you might have to just do re-create a new server.

That’s mostly just a Ubuntu thing. If you redo a new server you’d have the updates.

I recall I had to re-add the client to do mysql dumps. So perhaps something changed there. When I try to purge these packages I am told they have not been installed. MariaDB is up and running and databases are there.:

mysql -u root
Welcome to the MariaDB monitor.  Commands end with ; or \g.

MariaDB [(none)]> 

so it must have been installed differently. This also causes issues running dpkg while provisioning. I am told to run dpkg --configure -a and get:

I can always wipe the server post backing up all uploads and so on but prefer to see if I can remove this "rogue MariaDB and let Trellis install its own… Trying to figure out how to remove the current now and get around this issue.
