I installed MySQL Server 5.6, but soon after I had to install XAMPP.
When I try to start MySQL it just hangs at...
Attempting to start MySQL app...
The errors in the logs are as follows...

I tried stopping the MySQL56 service in services, but still it didnt work
I also tried changing ports in my.ini to 3307, but still no luck
I have obviously restarted everything after these changes but it just stays hanging on the attempt to start
Uninstall both and reinstall XAMPP with MySQL included. Many times these installs will run as administrators and then you won't have rights to modify them if it sees you as a different user.
You could also try right clicking on the icon to start XAMPP and choose "Run as Administrator" before uninstall / reinstall and see if that solves it.

I am trying to run MySql on my Virtual Machine. However, I encountered the following error and thus MySql cannot start up. I am new to MySql. Your help is really appreciated! Here is the message from the error log:

IF you read in carefully, first line enlightens the problem and the second line advises solution for it.
run mysql_upgrade to fix it.
Seems, you didn't set path of your ibdata1 or you removed ibdata1 file. Please check my.cnf and set below parameter in my.cnf.
innodb_data_home_dir (path of innodb)
innodb_data_file_path (for example: ibdata1:10M:autoextend)
Note: If it's new setup then also enable innodb_file_per_table
One of our servers was the subject of a ransomware attack from a group of international Hackers. So we’ve re-grouped and started over and the only unaffected data we had was the ibdata1 file stored in mysql program data folder.
We would like to restore that data on the new instance so that we carry forward our operations but after trying to run the new installation of mysql it the service stops with error 1067. It suggests to delete all files created by InnoDB: all ibdata files and all ib_logfile files. If I do that the service will run but I can’t do it because I need to access the data in this particular data file. I’ve also added these two lines in my .cnf file
innodb_force_recovery=6
innodb_fast_shutdown=0
That hasn’t worked. So I deleted just the log files and it created new log files along with it came this error

It appears there is a check point somewhere in the log files that is necessary for the data file to be read properly by the mysql service. Maybe I need to specify the log file size in the my.ini config file. But I don’t know how to go about it.
Any help will really come in handy here.
In your my.ini (or my.cnf) file, add (or replace) the following line:
innodb_log_file_size = 1024M
See https://dev.mysql.com/doc/refman/5.6/en/innodb-parameters.html#sysvar_innodb_log_file_size for details.
I was in the middle of developing my site and both apache and mysql were running normally until suddenly, the database failed to connect. I checked my XAMPP control panel and MySQL had stopped running. I searched for a solution here and some other similar questions on SO but i haven't been able to find a solution that works for me. Here is the contents of mysql_error.log file:

What i have tried until now:
i have changed to port address for from 3306 to 3307, 3310. Didn't work.
i deleted ibdata1 file. Although the file reappeared back in its place after i attempted to restart MySQL. (I learnt later that i would lose my tables if ibdata1 is missing. i don't want that.)
Why did MySQL suddenly run into problems and and how to start MySQL without losing my tables?
There are several reason MySql keeps shutting down unexpectedly.
I am assuming that you have not installed multiple mysql server versions in the same machine.
Stop Mysql service from xampp control panel or stop it manually from services.msc and quit the xampp control panel.
Delete these two log files (ib_logfile0 and ib_logfile1) from xampp/mysql/ directory. (Note: I am not sure about the exact path of log files, check in all the folders of xampp/mysql/ directory)
Restart Mysql service manually from services.msc
open xampp control panel, you should see mysql is running.
I also see your innodb_buffer_pool_size is very low.
Increase the buffer_pool_size to about 50-60% of your RAM. For example, If you have 2GB ram, then set buffer_pool_size= 1GB
run this query in mysql.
set innodb_buffer_pool_size=1073741824;
or
set global innodb_buffer_pool_size=1073741824;
restart mysql server.
I have installed MySQL Workbench on my computer that is using port 3306.
I installed Xampp apache server. When I start the services this error appears:
Problem detected!
Port 3306 in use by ""C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqld" --defaults- ile="C:\ProgramData\MySQL\MySQL Server 5.6\my.ini" MySQL56"! MySQL WILL NOT start without the configured ports free!
You need to uninstall/disable/reconfigure the blocking application or reconfigure MySQL and the Control Panel to listen on a different port
I changed the mysql port for xampp in the following way:
Stop the xampp server, if it is already running.
Edit the value to "port" in xampp/mysql/bin/my.ini
Code:
Password = your_password
port = 3306 ---> 3307
socket = "/ xampp / mysql / mysql.sock"
and here also
Code:
The MySQL server
[ mysqld ]
port = 3306 ---> 3307
socket = "/ xampp / mysql / mysql.sock"
And Started mysql service however the error remains.
Does someone can help me solve this please?
thank you all
best regards

This sounds a lot like you got two MySQL servers running at the same time. I suggest you check your process list for a process called mysqld.exe. (You can also check the "Netstat" as provided by Control Panel) This should be your already running instance of MySQL Server. End that one however you like and try again.
In your case I'd also consider installing the MySQL server as windows-service. This allows you to "externally" manage the server and make sure you only have one instance running.
You can accomplish that by clicking the red x beside the Modulename and wait for it to turn into a green checkmark.
After that your Control Panel should looks something like that ▲▲
I installed both MySQL and Apache as service, but that's your preference ;)
You can then configure your MySQL Workbench to access your already running server instead of starting up its own.
You shouldn't be required to change the port of MySQL in any case.
In addition to that, your Apache Module should be able to launch even without MySQL started...
I am facing this weird issue. Suddenly mysql stops working and i am getting error log in /var/log/mysql/error.log

Its very itching problem as I can write a single code without myqsl connection. How to solve this issue.
PS: Sorry Ubuntu fellas as I am using 13.04 unsupported version, I have already installed 14.04 and will move to it in a couple of days.
After going through lots of suggestions I found in stackoverflow and other mysql related websites, I did not success to fix this issue. then I reconfigure my mysql installations and voila its working now.
Command I used is
sudo dpkg-reconfigure mysql-server-5.5
