OS X – Fail to start MySQL server which is installed by Homebrew

After i reboot my OS X, i find that i couldn’t start the MySQL server and it throws the following error:

hatuey:5.6.19 yingkityuen$ mysql.server start
Starting MySQL
. ERROR! The server quit without updating PID file (/usr/local/var/mysql/hatuey.local.pid).

 

Go to the above folder and delete the mysql error log which is ended with .err. In my case, i executed the following command:

hatuey:5.6.19 yingkityuen$ rm /usr/local/var/mysql/hatuey.local.err

Where hatuey is my Mac machine name.

This should fix the problem.

Done =)

Installation on Ubuntu:

Here is a great article written by Jonathan Jackson about the two solutions.

 

For Mac users, you could install rbenv using Homebrew. Otherwise, you need to checkout the repository on GitHub.
