[Rails] Re: rake aborted!

this is my database.yml content:

# MySQL. Versions 4.1 and 5.0 are recommended.
#
# Install the MySQL driver:
# gem install mysql2
#
# And be sure to use new-style password hashing:
# http://dev.mysql.com/doc/refman/5.0/en/old-client.html
development:
adapter: mysql
encoding: utf8
reconnect: false
database: cms_development
pool: 5
user: smtabatabaie
password: 'mypassword'
host: localhost

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: mysql
encoding: utf8
reconnect: false
database: cms_test
pool: 5
user: smtabatabaie
password: 'mypassword'
host: localhost

production:
adapter: mysql
encoding: utf8
reconnect: false
database: cms_production
pool: 5
user: smtabatabaie
password: 'mypassword'
host: localhost

--------------------------------------------------------------------------
I enter mysql using commands : mysql -u smtabatabaie -p
and then : show databases
and cms_development is there
