Answer 1

If you use Percona Mysql server

$ yum install Percona-Server-devel-55

$ gem install mysql

Answer 2

First of all you need to differentiate between the MySQL as Server, MySQL as Client and the Ruby bindings to MySQL.

I'm not familiar with Mac, but for *nix OS you need to install MySQL through your package manager. To get the Ruby bindings installed with

gem install mysql

you need the development headers of ruby (in Ubuntu it is the package ruby-dev) and the development headers of the MySQL-Client (currently libmysqlclient16-dev in Ubuntu). I don't know if they are named different on Mac, but after you got those installed the Ruby bindings should install without any error.

Answer 3

I had a similar experience, so here are the things that I tried

Firstly, I tried to install mysql's required packages by running the command below in my terminal

sudo apt-get install build-essential libmysqlclient-dev

Secondly, I tried updating rubygems on my system by running the command below in my terminal

sudo gem update --system

But I was still experiencing the same issue. After much research I realized that I was using an almost out-of-date version of the mysql gem. I simply needed to use the mysql2 gem (mysql2 gem)and not the mysql gem, so I fixed it by running the command below in my terminal

gem install mysql2

This worked fine for me. Before running the last command, ensure that you've ran the first and second commands to be sure that everything is fine on your system.

That's all.

I hope this helps
