I then went to attempt to start mysql, as I guess this is a common issue with this, but it just gave a generic error. I went through troubleshooting the mysql.sock file and everything, changing its permissions, but nothing is working. I have rebooted my NAS many times. I eventually tried to restart mysql. In doing so I get:
I can't find anything specific to the QNAP or any general type troubleshooting for this. Everything I find seems to be OSX related.

ERROR! MySQL server PID file could not be found! This might be due to issues with disk space, disk inode usage or innodb corruption which may lead to the error. The issue was with the pid file and the solution was:
3) Create a file with name as mysqld.pid
Done! answered Oct 16, 2017 at 5:35
0 I had the same issue. It turns out I added incorrect variables to the my.cnf file. Once I removed them and restarted mysql started with no issue. answered Aug 9, 2014 at 6:04
Check if your server is full first, thats a common reason (can't create the PID file because you have no space). Run this to check your disk usage..
If you get something like this, you are full..
In that case, you need to start looking for what to delete to make room, or add an additional drive to your server.
