2 つのサーバーでいくつかの sipmlest 設定があります。最初（192.168.250.199）にはdjangoがあり、別の（192.168.250.200）にはmysqlサーバーがあります
192.168.250.200:/etc/my.cnf
[mysqld]

max_allowed_packet=64M
# Default to using old password format for compatibility with mysql 3.x

[mysqld_safe]

}
だから私は「python settings.py syncdb」を実行してデータベースを同期しようとします
python manage.py syncdb

このエラーは「Mysql データベース接続が拒否されました」と呼ばれ、コンソールから直接接続しようとすると、mysqld の設定を探す必要があります。

無事！Django プロジェクトでは、これ以上具体的な設定はなく、ローカル データベースを使用して正常に動作します (はい、ローカルの my.conf をリモート サーバーに配置しようとしましたが、効果はありません)。
- selinux、iptables、その他のセキュリティ関連のものはありません
- Redhat らしい OS (CentOS および Scientific Linux) を使用する
私の問題をうまく説明できたことを願っています。ありがとう。
