我刚刚使用MySql创建了一个新的Rails 4应用程序,如下所示:
rails new mysqltest -d mysql
并使用正确的凭据修改了database.yml。
我生成了一个示例控制器并更新了根路由的路由。
当我开始在生产中使用WEBrick时,
rails s -e production
该网站有效。我看到了索引页面。
当我开始使用没有3000端口的Passenger时,我看到以下错误:
database configuration does not specify adapter (ActiveRecord::AdapterNotSpecified)
Passsenger正在生产环境中运行。
我的database.yml
# MySQL. Versions 4.1 and 5.0 are recommended.
#
# Install the MYSQL driver
# gem install mysql2
#
# Ensure the MySQL gem is defined in your Gemfile
# gem 'mysql2'
#
# 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: sample
pool: 5
username: sample
password: sample
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: sample
pool: 5
username: sample
password: sample
socket: /var/run/mysqld/mysqld.sock
production:
adapter: mysql2
encoding: utf8
database: sample

我在database.yml文件和apache配置文件中使用的情况不同。
两者都应该相同。例如。 production
。
在apache配置中,我给出了Production
。将其更改为production
后就可以了。

您是否创建了本地生产数据库?
rake db:create:all
RAILS_ENV=production bundle exec rake db:migrate
您的database.yml文件是否已正确设置以使用生产数据库?
你的gem文件中是否有mysql gem。
