Q&A
ローカルで作成したアプリをaws,nginx,unicorn,postgresqlを使用してデプロイしようとしています。
インターネットで掲載されている情報を元にrailsアプリをデプロイするところまできました。しかし、ec2に関連付けているEIPにアクセスすると we're sorry, but something...といういつものやつが表示されてしまいます。
私だけでは解決に至ることが難しいと悟り、ご存じの方いましたらお力添え頂きたいです。
$ tail -n 30 production.log コマンドを行ったところ下記logが返ってきました。
$ rails assets:precompile コマンドは行っていますがアセットパイプラインの設定等がおかしいのかと考えています。
