自動デプロイにてunicorn:startで止まってしまうエラーを解決したい。

前提・実現したいこと

Capistranoを用いた自動デプロイをできるようにしたい。
現在自動デプロイを行うためにCapistranoを実装し、デプロイを行いました。
しかしデプロイの途中で止まってしまい、困っています。

試したこと

エラーログに

Unknown database 'kirakushare_production' (ActiveRecord::NoDatabaseError)

との記載があるので、

AILS_ENV=production DISABLE_DATABASE_ENVIRONMENT_CHECK=1 bundle exec rake db:drop
```を実行し、削除して再度
```ruby
rails db:create RAILS_ENV=production
```を行った。
