installing mysql gem on rbenv - mysql

Question

I'm trying to use vagrant on my MAC OSX machine. I connected vagrant with using SSH and I set ruby 1.9.2-p290. Now I'm try to install ruby gems but I've been facing with this problem when I want to install mysql2 gem.
Fetching: mysql-2.8.1.gem (100%)
Building native extensions. This could take a while...

Gem files will remain installed in /home/vagrant/.rbenv/versions/1.9.2-p290/lib/ruby/gems/1.9.1/gems/mysql-2.8.1 for inspection.
Results logged to /home/vagrant/.rbenv/versions/1.9.2-p290/lib/ruby/gems/1.9.1/gems/mysql-2.8.1/ext/mysql_api/gem_make.out
I set in Gem file
gem 'mysql2'
and again I run bundle command but the result is the same.
Why doesn't mysql run on vagrant?

Answer 1

The mysql2 gem has native C extensions that build against mysql binaries.
Your vagrant machine needs to have mysql installed.
Do something like this
$ vagrant ssh
$ sudo apt-get install mysql-server mysql-client
After mysql is installed, you should be able to install the mysql2 gem.
EDIT: you also need the mysql development libraries so
$ sudo apt-get install libmysqlclient-dev libmysqlclient16 ruby-dev
