Tasks: TOP => db:schema:dump
I already create the database and Im having this problem when I try to connect.
My database.yml is:
# SQLite version 3.x
# gem install sqlite3
#
# Ensure the SQLite 3 gem is defined in your Gemfile
# gem 'sqlite3'
# development:
# adapter: sqlite3
# database: db/development.sqlite3
# pool: 5
# timeout: 5000
development:
adapter: mysql2
encoding: utf8
reconnect: false
database: simple_cms_develoment
pool: 5
username: simple_cms
password: secretpassword
socket: /tmp/mysql.sock
# 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: sqlite3
database: db/test.sqlite3
pool: 5
timeout: 5000
production:
adapter: sqlite3
database: db/production.sqlite3
pool: 5
timeout: 5000
And my gemfile is:
source 'https://rubygems.org'
gem 'rails', '3.2.9'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'mysql2'
gem 'activerecord-mysql-adapter'
gem 'bootstrap-sass'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the app server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'debugger'
Can anyone help me?
Assuming you are using ubuntu, you have the wrong path to the socket file
changed to
socket: /var/run/mysqld/mysqld.sock
