gem 'mysql2'

config/database.yml

  adapter: mysql2
  pool: 5
  timeout: 5000
  username : root #mysql username
  password : root #mysql password

development:

Add mysql2 gem and remove other connection gem required for sql server.

# Gemfile
# gem 'tiny_tds'
# gem 'activerecord-sqlserver-adapter', '~> 4.2.0'
gem 'mysql2'

database.yml

default: &default
  adapter: mysql2
  encoding: utf8
  pool: 5
  socket: /tmp/mysql.sock

development: &development
  <<: *default
  host:     yourhostfordevelopement # commonly localhost
  database: yourdb # for development
  username: dbusername # commonly root
  password: dbpasseord # password you configured

development_vehicle: &development_vehicle
  <<: *default
  host:     yourhostfordevelopement # commonly localhost
  database: yourdb # for development_vehicle
  username: dbusername # commonly root
  password: dbpasseord # password you configured

development_aspnet: &development_aspnet
  <<: *default
  host:     yourhostfordevelopement # commonly localhost
  database: yourdb # for development_aspnet
  username: dbusername # commonly root
  password: dbpasseord # password you configured
