ELBを利用したEC2インスタンスに、Djangoをデプロイする際のHOST問題

2
Last updated at Posted at 2019-06-06

ホスト名を記述しておかないと、アクセスできない件

この場合、下記２点を予めsettings.pyのALLOWED_HOSTSに記載しないとアクセスが拒否される現象が発生します。

  • ELBのDNS name
  • EC2のPrivate IPs

ちなみに、ELBのDNSを独自ドメインで利用する場合(CNAMEを使用）、そのドメイン名をDNS nameの代わりに記入する必要があります。（例：お名前ドットコムのドメイン名を使用したい）

settings.py
ALLOWED_HOSTS = ['ELBのDNS', 'EC2のprivateIP']
