How to connect Rails with MySQL? [duplicate] - mysql

"Access Denied" when rails connects to Mysql
(3 answers)
Closed 8 years ago.
I have the following running correctly:
rails new simple
rails server (working)
rails generate controller demo index
mysql -u root -p and creating the database and assigning GRANT PRIVILIGES on the database is done.
Now the problem is, I used the Bitnami-RubyStack packages on my MAC 10.7. When I want to run rake db:schema:dump, I get this error:
bash-3.2$ rake db:schema:dump
rake aborted!
Access denied for user 'root'#'localhost' (using password: YES)
/Applications/rubystack-1.9.3-18/simple/config/environment.rb:5:in `<top (required)>'
Tasks: TOP => db:schema:dump => environment
(See full trace by running task with --trace)
even if I run GRANT PRIVILEGES.
Also I checked the username and password on my DB.yml:
development:
adapter: mysql2
encoding: utf8
reconnect: false
database: simple_development
pool: 5
username: root
password: something
socket: /tmp/mysql.sock
host: 127.0.0.1

Answer 1

In your database config
development:
adapter: mysql2
encoding: utf8
reconnect: false
database: simple_development
pool: 5
username: root
password: something
socket: /tmp/mysql.sock
host: 127.0.0.1
you should use either socket or host, not both. Since socket works for you (mysql -u root -p works), try using it with your app. If there's any permission problems or whatnot, you are going to have to create root#127.0.0.1 in your mysql console and use the host parameter.
