DB failing on reprovision #2

The DB breaks when trying to reprovision with MariaDB.

My system:

  • OSX Catalina 10.15.4
  • Vagrant 2.2.7
  • VirtualBox 6.1.4 r136177 (Qt5.6.3)
  • No other current vagrants

Steps to reproduce:

$ git clone --recursive https://github.com/Chassis/Chassis test
$ cd test
$ mkdir -p content/{themes,plugins}

Add the MariaDB extension to the vanilla config.yaml:

extensions:
  - chassis/mariadb

Create the vagrant:

$ vagrant up

The vagrant is created and works without issue. However, when I attempt to reprovision, the DB setup breaks:

The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.

The DB is now inaccessible and doesn't work:

$ vagrant ssh
-- SSH into vagrant ---
vagrant@vagrant:~$ mysql -uwordpress -pvagrantpassword wordpress
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

However, I can get the DB working again by manually reinstalling MariaDB:

vagrant@vagrant:~$ sudo apt -y install mariadb-server

This breaks as soon as I reprovision again, necessitating another cycle of manually running sudo apt -y install mariadb-server.

@banderon Thanks so much for reporting this. I haven't tested this extension much since I created it so I'll have a look now and see if I can replicate and make a fix for it!

I started having a look into this issue yesterday and it turns out that none of the class I was trying to inherit in here: https://github.com/Chassis/MariaDB/blob/master/modules/mariadb/manifests/init.pp#L29-L46 was being used at all so I need to reimplement that or handle it in a different way so that the mysql socket is opened correctly and I might also need to pass in some innodb specific settings. I should be able to dig into that again in the next day or two.

I just spent a few hours trying to get a fix for this but I'm still stuck unfortunately. On an initial provision if I SSH into the box and run sudo find / -type s the socket we need has been created. /run/mysqld/mysqld.sock when we reprovision that socket isn't recreated. I think that when sudo apt -y install mariadb-server runs it purges all the existing sockets and sets them up again. I can't work out why the Puppet MySQL class that has MariaDB doesn't do this.
