なので User モデルを参照する必要がある場合は django.contrib.auth.get_user_model() を使用する必要があります。
# account/admin.py
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from .models import User # models.py のカスタム User をインポート
admin.site.register(User, UserAdmin)
マイグレーション
まず、新たに作成した「account」アプリケーションのマイグレーションを作成します。
% python manage.py makemigrations account
Migrations for 'account':
account/migrations/0001_initial.py
- Create model User
マイグレーションを実行します。
% python manage.py migrate

Nginx はデフォルトで「/var/www/html」というディレクトリを作っていますが、今回は /var/www/ の配下にドメイン名のディレクトリ、そしてその配下に html というディレクトリを作ります。（イメージ：/var/www/example.com/html）
vpsadmin@xx1-234-56789:/var/www$ sudo mkdir -p example.com
[sudo] password for vpsadmin:
