How to fix MySQL not running on AWS Bitnami Wordpress problem? - mysql

I had disk storage issue on my AWS EC2 instance. To solve this problem, I wanted to increase the volume in my EC2 instance. To do so, I had to stop my instance. When I start it again, MySQL was not going back to live.
What I assume is that either I had lost some certain files or the settings has been changed after I stopped the instance. But I could not figure that out from the log file.

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.

Issue with MySql installation on Windows 10

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 :)
Here is my error log:

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! :)

MySQL server erroring

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
