3000番ポートではなく80番ポートで接続させたい 【Rails / EC2】

Question

##前提・困っていること
現在RailsアプリをAWS上にデプロイをしたいのですが、EC2のセキュリティグループで詰まっています。

サーバーはデフォルとのPuma使用しています。

下記のように3000番ポートにアクセスできるようにし、bundle exec rails s -b 0.0.0.0で接続できなのですが、

下記のように3000番ポートではなく80番ポートでアクセスできるようにしたのですが接続できません。

またこのとき、rails serverに接続する際のコマンドは3000番ポートに接続したコマンドと同じく
bundle exec rails s -b 0.0.0.0 で接続するのしょうか。

ご教授いただけましたら幸いです。

##追記

$sudo rails s -b 0.0.0.0 -p 80

Answer 1

sudo rails s -b 0.0.0.0 -p 80

ポート指定すれば良いと思います。
80番はsudo しないと開かないかもしれません。

ご回答ありがとうございます。

sudo rails s -b 0.0.0.0 -p 80を実行しましたら、別のエラーが発生しました。
追記しましたのでご教授いただけましたら幸いです。

Permission denied - bind(2) for "0.0.0.0" port 80 (Errno::EACCES)
ですね。
pumaは -p 3000で apacheかnginxを リバースプロキシ設定するのはいかがでしょうか？
そのほうがトラフィックが増えたときマルチインスタンスもできますし、https化も簡単だと思います。

/home/ec2-user/.rbenv/versions/2.7.2/lib/ruby/gems/2.7.0/gems/puma-5.2.1/lib/puma/binder.rb:288

なので、rootアカウントのrailsが動いていない感じです。
rootアカウントにrailsもgemも全部載せないといけないのでやはりおすすめはリバースプロキシです。
