2. Go to config/database.yml development:   adapter: mysql   database: development   username: root   password: PASSWORD   host: localhost   socket: /var/lib/mysql/mysql.sock   timeout: 5000 Now rails can connect to the database. If not, you have to make database in mysq command line mysql -u root -p create database development;
