Next, we need to find out the credentials for our database:

'mysql' execution failed; is it in your $PATH?

I need to install a proper mysql client with sudo apt-get install mysql-client-5.5. Now we need to get the credentials of the database:

$ cf tunnel

3: mysqldump

You can find the code https://github.com/matthias-guenther/hello-world-padrino-anynines-mysql

Hey Matthias,

I'm happy to see your results using anynines.

I have one suggestion for your gist:

Instead of manually adding the db credentials to your config you could read them from the vcap_services environment variable. This is an example where swift service credentials are reead from the environment: https://github.com/anynines/paperclip_demo/blob/master/config/initializers/paperclip.rb#L32

Cheers,
Julian W

Hi Julian, thanks for your help and I know what you mean. I add the following settings in my config/database.rb:

ActiveRecord::Base.configurations[:production] = {
  :adapter   => 'mysql2',
  :encoding  => 'utf8',
  :reconnect => true,
  :database  => JSON.parse(ENV["VCAP_SERVICES"])["mysql-5.5"].first['credentials']['name'],
  :pool      => 5,
  :username  => JSON.parse(ENV["VCAP_SERVICES"])["mysql-5.5"].first['credentials']['username'],
  :password  => JSON.parse(ENV["VCAP_SERVICES"])["mysql-5.5"].first['credentials']['password'],
  :host      => JSON.parse(ENV["VCAP_SERVICES"])["mysql-5.5"].first['credentials']['hostname'],
  :socket    => '/tmp/mysql.sock'
}

And after running cf push --command "PADRINO_ENV=production bundle exec rake ar:migrate" the app crashed again with the following output:

Using manifest file manifest.yml

Again, problems with the connections. Maybe it's a port problem or something else?
Thanks for your help.

Hey Matthias,

sorry for the delayed response.

This is what i did to make it work:

• Port -> database.rb:
  ActiveRecord::Base.configurations[:production] = {
  :adapter => 'mysql2',
  :encoding => 'utf8',
  :reconnect => true,
  :database => JSON.parse(ENV["VCAP_SERVICES"])["mysql-5.5"].first['credentials']['name'],
  :pool => 5,
  :username => JSON.parse(ENV["VCAP_SERVICES"])["mysql-5.5"].first['credentials']['username'],
  :password => JSON.parse(ENV["VCAP_SERVICES"])["mysql-5.5"].first['credentials']['password'],
  :host => JSON.parse(ENV["VCAP_SERVICES"])["mysql-5.5"].first['credentials']['hostname'],
  :port => JSON.parse(ENV["VCAP_SERVICES"])["mysql-5.5"].first['credentials']['port']
  }
• Migration Command:
  cf push --command 'RACK_ENV=production bundle exec rake ar:migrate'
• Start Command:
  cf push --command 'RACK_ENV=production bundle exec padrino start -p $PORT -h $VCAP_APP_HOST'
