rake db:create - getting a syntax error

thank you everyone for helping me out with this. i am new to ruby on rails

here is my database.yml file::

# MySQL.  Versions 4.1 and 5.0 are recommended.
#
# 

Install the MySQL driver:
#   gem install mysql
# On Mac 

OS X:
#   sudo gem install mysql -- --with-mysql-

dir=/usr/local/mysql
# On Mac OS X Leopard:
#   sudo env 

ARCHFLAGS="-arch i386" gem install mysql -- --with-

mysql-config=/usr/local/mysql/bin/mysql_config
#       

This sets the ARCHFLAGS environment variable to your 

native architecture
# On Windows:
#   gem install mysql
#   

    Choose the win32 build.
#       Install MySQL and put 

its /bin directory on your path.

test:
  adapter: mysql
  encoding: utf8


database: blog_test
  username: root
  password:
  host: 

localhost

production:
  adapter: mysql
  encoding: utf8


database: blog_production
  username: root
  password: 


host: localhost

when i do a rake db:create

i am getting this error:

syntax error on line 20 col 1: ' pool: 5 username: root'

thank you again for your help

Shouldn't that read:

pool: 5
username: root

... on separate lines?
