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.

I have no mysql instances running. Any help here will be appreciated. Thanks
Turns out the problem was with my filesystem. That's why MAMP PRO did not work. A friend helped me set up my laptop at the beginning and we chose the Apple File System (APFS) which is case-insensitive. Then I created a partition of the disk and formatted it to have Mac OS Extended (Case-sensitive, Journaled). That's when everything worked.

I have tried to apply various solutions including this - MySQL Fatal error: Can't open and lock privilege tables: Incorrect file format 'user'
Unfortunately, I am not able to access Mysql and therefore unable to follow the solution. $ sudo mysqld --skip-grant-tables does not allow me to access it.
UPDATE: Solved! Here is my solution:
Todays systems are often running on a disk which is formatted in GPT. This is because Windows 10 needs such a partition to be installed. The problem is that MySql cant deal with this partition style and so it crashes. Here is my workaround:
Create a virtual disk: manual here
Format this VHD with MBR
Install MySql custom on your new VHD (dont forget to create a user
for DB)
This should be it! :)
I try to install MySql on my Dell XPS 13 9360 with Windows 10. When it comes to starting the server as a service, the service cannot start. As so far this problem is widely known and there are many attempts to solve this issue. Unfortunately non of these work for me. Here is what I tried:
insert innodb_flush_method=normal into my.ini
change service to register at local account
check firewall for port rules
So my question: Does anybody experience the same issue and knows a way to get it running? You would help me really so much :)

Found the solution:
Todays systems are often running on a disk which is formatted in GPT. This is because Windows 10 needs such a partition to be installed. The problem is that MySql cant deal with this partition style and so it crashes. Here is my workaround:
Create a virtual disk: manual here
Format this VHD with MBR
Install MySql custom on your new VHD (dont forget to create a user for DB)
This should be it! :)
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.
From error.log I have

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
