This is the application log:

Answer 1

I just solve the answer by going to the activity monitor and search for sql under all process and terminate it. then i restart my mac and now my sql database is working great for me.

Answer 2

For me, Xampp Control panel was not launching, and in Stackoverflow some where it was mentioned to add Read / Write for every one on every file of xampp, when I did that. It allowed me to launch xampp control panel but mysql was not starting.

Later I debuged and found that /Applications/XAMPP/xamppfiles/etc/my.cnf should not be writeable by everyone, mysql will ignore my.cnf if it is for everyone. I changed the permission to read only for this file, and able to start mysql server

Answer 3

If mysql is not starting in xampp, it might be a port conflict issue. Mysql run by default on port 3306. you need to check if another application is occupying that port. use following command to check app occupying a port

lsof -nP -i4TCP:3306

if you find an application occupying that port, stop the application and restart xampp. As an alternative, you can go to php.ini file or click configure in the dropdown and change the mysql port to 3307

Answer 4

Xampp Control Panel> Manage Server> Mysql Database > Configure > change the port from 3306 to 3307

At least it worked for me in mac.

Answer 5

#1. Open XAMPP Installation Directory
#2. Open "etc" Folder
#3. Find "my.cnf" file and open it in any text editor
#4. Change Port from 3306 to 3307 (if you have installed skype or other apps)
#5. Add "innodb_force_recovery=1" under "myisam_sort_buffer_size=8M"
#6. Save "my.cnf" file
#7. Restart Mysql Server By Your Terminal by command:
"sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start" 

You Get A message "Starting MySQL SUCCESS! "

Answer 6

I Know this post was originally posted last year, but I just had the same problem and I found the solution for me. So here it is, just in case this can help somebody else.

I tried all the suggestions I found online, including trying to terminate MySQL on the activity monitor, but then I realized that when you download/upgrade XAMPP - MySQL, the option to automatically start MySQLserver on Startup is ON. You need to turn it off. Here is what you do:

Go System Preferences and click on the Mysql icon, You should get this window:

Uncheck that option. You will be asked for your password. After you are done with that, restart your computer and the problem should be fixed.

I hope that help somebody who is as confused as I was. lol ✌
