我正在尝试在Ubuntu平台上为mysql设置我的第一个Rails项目（JRuby）。我使用创建了项目 滑轨新MyFirstRailsProject -d mysql

现在，在使用rails服务器启动rails服务器时，出现以下错误。

rails server

我不知道我要去哪里。 以下是我的database.yml文件

# MySQL.  Versions 4.1 and 5.0 are recommended.
#
# Install the MySQL driver:
#   gem install activerecord-jdbcmysql-adapter
#
# Configure Using Gemfile
# gem 'activerecord-jdbcmysql-adapter'
#
# And be sure to use new-style password hashing:
#   http://dev.mysql.com/doc/refman/5.0/en/old-client.html
development:
  adapter: mysql2
  encoding: utf8
  database: #MyFirstRailsProject_development
  username: username
  password: password
  host: localhost
  port : 3306
  socket: /var/run/mysqld/mysqld.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: mysql2
  encoding: utf8
  database: #MyFirstRailsProject_test
  username: username
  password: password
  host: localhost
  port : 3306
  socket: /var/run/mysqld/mysqld.sock

production:
  adapter: mysql2
  encoding: utf8    
  database: #MyFirstRailsProject_production
  username: username
  password: password
  host: localhost
  port : 3306
  socket: /var/run/mysqld/mysql

My SQL Version is:
mysql  Ver 14.14 Distrib 5.5.61

JRuby版本：

jruby 9.1.17.0 (2.3.3) 2018-04-20 d8b1ff9

轨道版本

Rails 3.2.13

宝石文件：

source 'https://rubygems.org'

gem 'rails', '3.2.13'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'activerecord-jdbcmysql-adapter'

gem 'jruby-openssl'

# 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 'therubyrhino'

  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'

请任何人提供建议，我在这里做错了什么？ 是JRuby而不是Ruby->（那会有所作为吗？）
