Q&A
コードを提示しましょう
##知りたいこと
EC2にRailsアプリの本番環境を構築しています。
ウェブサーバーを起動できない問題が発生しており、ログを見るにおそらく設定の記述がどこか間違えているのだと思います。
調べてみてもunicorn+nginxという同じ組み合わせでも記述が異なっていたりして、どこが間違えているのか理解することができませんでした。
頼り方が安易で大変失礼とは承知なのですが、設定ファイルの中身を添削していただけませんでしょうか。
##起きている問題
###1、unicornが起動できない
bundle exec unicorn_rails -c config/unicorn.rb -E production -D
▼エラーメッセージ
master failed to start, check stderr log for details
▼ログ(unicorn.stderr.log)
999 I, [2020-09-20T04:16:29.231266 #18113] INFO -- : Refreshing Gem list 1000 bundler: failed to load command: unicorn_rails (/home/ec2-user/.rbenv/versions/2.6.6/bin/unicorn_rails) 1001 NoMethodError: undefined method `fetch' for #<アプリ名::Application:0x0000000003f5d1a8> ・ ・ ・
###2、データベースを作成できない
rails db:create RAILS_ENV=production
▼エラーメッセージ
rails aborted! NoMethodError: undefined method `fetch' for #<アプリ名::Application:0x00000000023c9ab8> /var/www/アプリ名/config/environments/production.rb:17:in `block in <main>' /var/www/アプリ名/config/environments/production.rb:1:in `<main>' /var/www/アプリ名/config/environment.rb:5:in `<main>' bin/rails:4:in `<main>' Tasks: TOP => db:create => db:load_config => environment (See full trace by running task with --trace)
他にもunicornの起動に関しては、Cannot load database configuration:というエラーが出たことがあったり、
I, [2020-09-19T07:00:51.913723 #9104] INFO -- : Refreshing Gem list bundler: failed to load command: unicorn_rails (/home/ec2-user/.rbenv/versions/2.6.6/bin/unicorn_rails) ActiveSupport::MessageEncryptor::InvalidMessage: Cannot load database configuration: ActiveSupport::MessageEncryptor::InvalidMessage ・ ・ ・
今日試した時にはNoDatabaseErrorも発生しています。
I, [2020-09-22T04:42:19.543564 #2605] INFO -- : Refreshing Gem list I, [2020-09-22T04:42:20.452976 #2605] INFO -- : listening on addr=0.0.0.0:3000 fd=9 E, [2020-09-22T04:42:20.454887 #2605] ERROR -- : Unknown database 'アプリ名_production' (ActiveRecord::NoDatabaseError) ・ ・ ・
###各設定ファイル
多分それぞれ原因は同じで、production.rbやdatabase.yml、unicorn.rbなどのいずれかが間違えているのではないかと思います。
以下関係ありそうなファイルです。

###試したこと
1、rails db:create RAILS_ENV=productionを実行する
実行した結果は前述の通りです。
2、マスターキー
"config直下にmaster.keyがないです"みたいなエラーが出たこともあって、今は配置済みです。
正直そこも、記事によって書いてあることが違う▼のがよくわからないのですが…
- アプリ/config/master.key
- アプリ/shared/config/master.key
最初はshared/configにマスターキーを置いていました。
今はアプリ直下のconfigにも配置してあり、本番環境にマスターキーが二つある状態です。
（これもエラーの原因になるのでしょうか？）
3、production.rbに追記したコードを削除
set :linked_files, fetch(:linked_files, []).push("config/master.key")
この一行を削除しました。
参考にした記事で「deploy.rbにこれを追記する」ということが書いてあったのですが、私の環境にはそのファイルがなかったためproduction.rbに書いていました。しかし調べるとCapistranoを導入していく中で生成されるファイルのようだったので「関係ないかな？」と思い削除しました。
###作業環境
- macOS Catalina
- Amazon linux2
- Ruby 2.6.6
- Rails 6
- unicorn 5.4.1
同じような質問を繰り返していて大変申し訳ありません。
ググるのも下手なら質問も下手……という具合でお恥ずかしい限りです。
もしこの質問文の中に不要な情報（あるいは不足している情報）等あればご指摘をお願いします。
同様の質問がSOJにあったので、定期的に確認してみては。
https://ja.stackoverflow.com/questions/70552
その部分だけではなくて、前後のログも合わせて確認してみてください。
エラーとして出てきているのがそこというだけで、根本原因がそことは限りません。
文字数制限におさまりきらなかったので、こちらにログの一部を記載します。
