参考サイトを元にAWSのEC2にdjangoアプリをデプロイしています。
今回nginxとgunicornを使いデプロイしようとしており、参考サイトの最後でブラウザに接続したのですが、「502 Bad Gateway」が出て上手くいかず困っています。
環境は参考サイトとほぼ同じで、DBにMYSQLを使っているだけの違いです。

エラーログについて調べましたが理解ができず行き詰まってしまいました。
至らない点が多々あるかと思いますが、よろしくお願いします。

これは、 nginx が 80 番ポートに bind しようとしたときに、すでに 80 番ポートが他のプロセスなどで使われていた、というものです。
sudo lsof -i :80
などを実行して、80 番ポートを使っているプロセスを特定し、そのプロセスを終了させてから、再度デプロイしてみてください。
