rails s
For Production just run
对于生产只需运行
Rails 4.2
bin\rails s -e production
Otherwise
rails s -e production
To setup production database if database in production does not exist then run
如果生产中的数据库不存在，则设置生产数据库，然后运行
Rails 4.2
bin/rake db:create db:migrate RAILS_ENV=production
Otherwise
rake db:create db:migrate RAILS_ENV=production
bundle exec rake db:create db:migrate RAILS_ENV=production
If DB already exists the:

Start server using -eoption.
使用-e选项启动服务器。
rails server -e production
And you can not deploy database. you needs migrations to run in production.
而且你不能部署数据库。您需要迁移才能在生产中运行。

To start your server in development mode you only need to run rails sit will start your app in dev mode as well as your database.
要在开发模式下启动您的服务器，您只需要运行rails s它就会在开发模式下启动您的应用程序以及您的数据库。
To start your server in production mode you need to migrate your database with bundle exec rake db:migrate RAILS_ENV=productionand then start your server in production using rails s -e productionor RAILS_ENV=production rails s
要在生产模式下启动服务器，您需要使用以下命令迁移数据库，bundle exec rake db:migrate RAILS_ENV=production然后使用rails s -e production或在生产中启动服务器RAILS_ENV=production rails s

In rails 5+ goto
在 Rails 5+ 中转到
config/puma.rb

您可以找到以下行
environment ENV.fetch("RAILS_ENV") { "development" }
change "development" to "production"
将“开发”改为“生产”
