MySQL: error on El Capitan OS after Yosemite OS update

Question

I have problems with MySQL on my MacBook. I had updated my OS from Yosemite to El Capitan before I installed MySQL server.

Now, when I try to run MySQL on Terminal, I got the error like this

ERROR! The server quit without updating PID file

Anyone can help me please? Thanks a lot!

Answer 1

Try updating your my.cnf file to set the location of the PID file manually. Here's how you do that.

In your Terminal run the following command.

ps -ax | grep mysql

This will list all the locations of the important mysql files. Look for the path of the --pid-file

I will look something like this:

--pid-file=/path/to/your/local/mysqld.local.pid

Copy the path of the mysqld.local.pid file

Next open your my.cnf file using nano

sudo nano /usr/local/mysql/my.cnf

Set the pid-file path at the end of your my.cnf file. Search for pid-file. If you can't find it, manually enter it at the end of your my.cnf file. This will tell mysql where to look for the PID file. Enter the path that you copied like the example below.

pid-file = /path/to/your/local/mysqld.local.pid

Close and save the file

Next restart mysql. You may need to do this twice to reset your PID error.

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

That should solve your problem! Good luck

Answer 2

I had to create the file my.cnf in /etc and add [mysqld] before the line pid-file = /path/to/your/local/mysqld.local.pid Finally it worked!
