2016-02-24 11:22:27 7304 [ERROR] Aborting
This means your port is block because another version of MySQL is running in the background.
Try this:
If you are using windows then open command prompt and run following command.
TASKKILL /F /IM mysqld.exe (Run 2-3 times)
And if you are using Linux or MAC OS then open Terminal and run following command.
