Can't access MySQL through XAMPP and phpMyAdmin

Question

I am using XAMPP and I am trying to access phpMyAdmin through http://localhost/phpmyadmin, but I'm getting this error message:

Error
SQL query: 

SHOW PLUGINS

MySQL said: 

#1 - Can't create/write to file '/var/folders/_y/gtpc137d1q9gkvsj0dsxjd040000gn/T/#sql9f2_8_0.MYI' (Errcode: 13)

I haven't tried to access it in a while so I don't know what has changed since the last time. Can anyone shed light on this for me? I've Googled and can't seem to understand what most people are talking about in related issues.

Also, my XAMPP won't connect to Apache anymore either (it just keeps giving me the loading image).

Here is the error I'm getting:

Answer 1

Following line in the log is the reason:

"Warning: World-writable config file '/Applications/XAMPP/xamppfiles/etc/my.cnf' is ignored"

As Rishi Kalia has pointed out already you have to set the correct permissions:

1. Open Terminal

2. Navigate to the XAMPP config folder

   cd /Applications/XAMPP/xamppfiles/etc/

3. Set permissions of my.cnf to 600

   sudo chmod 600 my.cnf

4. Restart MySQL.

Answer 2

I had to reset the permissions in my xampp folder because I needed to be able to INSERT images into a folder in the htdocs, via php from website I am building.

However after I changed the permission I got : Errcode: 13

The process listed above works but I am adding some additional notes for people who have no clue how to use the terminal.

1. Open Terminal

• The Terminal is in Applications/Utilities/Terminal

2. Navigate to the XAMPP config folder

• pwd shows the path listing to the current directory

• cd changes the current directory

• ls -a lists all the files in that directory

Enter this code into the terminal: cd /Applications/XAMPP/xamppfiles/etc/

3. Set permissions of my.cnf to 600

Enter this code into the terminal: sudo chmod 600 my.cnf

4. Restart MySQL

Voilà!
