ERROR! MySQL manager or server PID file could not be found! QNAP

Question

I am having an issue where MySQL isn\'t starting on my QNAP NAS.

I found this first by not being able to log in through phpMyAdmin - was getting error:

Answer 1

I tried everything above, but saw no results until I got a hint from here: https://superuser.com/questions/159486/how-to-kill-process-in-mac-os-x-and-not-have-it-restart-on-its-own

I eventually went over to the activity monitor in my Mac, force Quit the PID, and ran the command:

sudo /usr/local/mysql/support-files/mysql.server restart

The magic was done!!!

Answer 2

Note: If you just want to stop MySQL server, this might be helpful. In my case, it kept on restarting as soon as I killed the process using PID. Also brew stop command didn't work as I installed without using homebrew. Then I went to mac system preferences and we have MySQL installed there. Just open it and stop the MySQL server and you're done. Here in the screenshot, you can find MySQL in bottom of system preferences.

Answer 3

After doing setup of PHPMyAdmin, I was also facing the same problem,

• Then I just stopped the MYSQL server by going into System settings, and then started again, and it worked.

Answer 5

If you're using MySQL Workbench, the mysql.server stop/restart/start will not work.

You will need to login into the workbench and then click "shutdown server". See image attached.

Answer 6

Just run mysqld (don't run as root) from your terminal. Your mysql server will restart and reset everything like shown in the picture below:

And use a command like so:

mysql -u root -h 127.0.0.1
