I'm trying to change where mysql uses for temporary tables. I have a drive mounted at /media/E, and I've created a directory owned by root with permissions drwxrwxrwxt at /media/E/tmp.
I have changed tmpdir in /etc/mysql/mysql.conf.d/mysqld.cnf to point to this directory.
I then restart mysql like so:
username#grey:/media/E/tmp$ sudo service mysql restart
Yielding the following error:
Job for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.
Here is the result of systemctl status mysql.service:

MySQL is armored by AppArmor, which does not allow writing freely to /media/E/tmp. To remedy the situation, you can edit the /etc/apparmor.d/abstractions/user-tmp and add the /media/E/tmp there appropriately; for me the extra lines
owner /media/E/tmp/** rwkl,
/media/E/tmp/ rw,

I have 4 containers using mgt-commerce/mgt-development-environment-7.2. Basically everything runs well until I cannot access the control panel. It returns 500.
After checking the services, logs, etc, it seems like mysql is unable to start. Here is the error log captured in /var/log/mysql/error.log during starting mysql service using sudo service mysql start.

Is there anyone using this image ever getting this kind of error?
Update
It seems like mysql doesn't have the access to a particular file(s) or directory(ies), but I'm not sure which file(s) or directory(ies) . Here is the permission of mysql data directory:
clp#magento2dev:/$ ls -la /var/lib | grep mysql

Can You explain what happened?
I can't start in xampp
What configuration should I change ?
I already change /var/lib/mysql/ to chmod 777

You must check rights on your filesystem :
The innodb_system data file 'ibdata1' must be writable
The folder containing ibdata1 seems to not be writable by mysql user.
I have the same problem and the file ibdata1 is indeed writable -rw-rw--w-.
The full path of this file is at /usr/local/var/mysql/ibdata1.
But it doen't help if I make the file writable by all -- I get the same error.
Stumbled upon an answer by remove *.err and it did it for me! Hope it helps you.
I have tried everything from every forum, still no love. Deleted temp files, even a totally clean re-install.
Even created a new user on my Mac.... same issue.
Here's the MySQL log file:

Run the code in terminal and restart MAMP server.
I did look up the web for a solution such as this very relevant post on SO, to no avail.
Here is the steps that I installed mysql for win 10 and attempts to start it:
downloaded mysql 5.7.18 zip file and unzip it into my app folder;
open "cmd" as admin and run "mysqld --install", it shows "Service successfully installed."
run "net start mysql", it shows:
The MySQL service is starting.
The MySQL service could not be started.
The service did not report an error.
More help is available by typing NET HELPMSG 3534.
Run "mysqld.exe --console", it chunked out lines of messages like below:

In MySQL installation root folder (suppose it is c:\mysql), create a text file, say mypass.txt and copy this line to it:
ALTER USER 'root'#'localhost' IDENTIFIED BY '<yourpassword>';
The run
mysqld --initialize
mysqld --init-file=c:/mysql/mypass.txt
And if you want to run MySQL as a Windows Service:
mysqld --install MySQLXY --defaults-file="c:/mysql/my.ini"
I've a MySQL server which I'm writing to about every 10 minutes. It seems to work fine then when I go back to it a few hours later it has crashed.

This is a database I'm running from Python/Django, not that I think that should make any difference. I do not know what is going wrong but if I reboot the server it starts up and works fine. Could you help please.
I increased the size of the server and it has been working fine. I'll live with it
