rails5+nginx+unicorn本番環境でアプリのルートファイルが表示できません。

Question

rails5+nginx+unicorn本番環境でアプリのルートファイルが表示できない

app/views以下に設定したrootページが表示できないです。
試しにapp_name/public/にindex.htmlを置くとapp_name/public/index.htmlは表示されpublic/assets以降も表示できるような状況ですが、app_name/public/からindex.htmlを削除して、本来表示したいroutesに設定したhome#indexが表示せずに403 Forbiddenと返ってきます。

rails server -e production

ローカルで本番環境を確認してもrootで設定したファイルが表示されます。

nginx/error.logエラーログは以下です。

2018/05/12 12:31:47 [error] 13982#13982: *1 directory index of "/home/user_name/rails_app/public/" is forbidden, client: ***.*.***.***, server: example.com, request: "GET / HTTP/2.0", host: "example.com"

/home/user_name/rails_app/public配下にindex.htmlを置くとページは表示される状況です。

publicのパーミッションは以下になります。

drwxrwxr-x 3 nginx user 4096 5月 11 15:53

rails_app/config/routes.rb

Rails.application.routes.draw do
  get 'home/index'
  root :to => 'home#index'
end

nginxで.confは以下の3つで設定しています。

nginxのエラーログってどうなってますか？また、railsのターミナルにエラーは出ていますか？

[Banksy]

情報追記いたしました。

Answer 1

nginxから"/home/user_name/rails_app/public"このファイルへのアクセス権が無いように思われます。
パーミッションを確認してみてはどうでしょうか。

[Banksy]

ありがとうございます。
/home/user_name/rails_app/public配下にindex.htmlを置くとページは表示される状況でして、
drwxrwxr-x 3 nginx user 4096 5月 11 15:53 publicとなっております。

Answer 2

nginx ではなく、rails の config/routes.rb ファイルを以下のように書き換えてみてください。

Rails.application.routes.draw do
  root 'home#index'
end

Rails.application.routes.draw do
root 'home#index'
end

上記試しましたが解決しませんでした。
