[LINUX] A record of the time it took to deploy mysql on Cloud9 + Rails

-Try to create a Rails application with Cloud9 + Rails + MySQL. ・ It takes time to install MySQL. -Since rails new was already executed, when mysql is described in Gemfile and bundle install is executed, an error occurs.

An error occurred while installing mysql2 (0.5.2), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.5.2' --source 'https://rubygems.org/'` succeeds before bundling.

procedure

https://qiita.com/kumas/items/e2c647dca08fd46b5c7a I created the application with reference to this, but it took time because of lack of knowledge.

① Move to the created directory and execute rails new

② In Gemfile

gem 'sqlite'
#Change default sqlite to MySQL

gem 'mysql'

③ The above error when executing bundle install

sudo yum install mysql-devel

It is said that it will be solved with, but this is also returned with an error and I am sorry. ..

The solution

sudo apt-get install libmysqld-dev

"No, I chose Ubuntu when creating cloud9 environments. Is that an error?" When I looked it up, it was. Or rather, I didn't understand the basics.

If you are using the RedHut yum command with a different package format in the Ubuntu environment, you will get an error. Transcendence Basically, you have to understand the format of Linux package files.
