プロジェクト構造を変更した後のNginx Bad Gateway

Question

私はAWSでホストされているdjangoアプリを持っており、プロジェクト構造のいくつかの面を整理しています。これらのクリーンアップの1つには、ルートディレクトリの親フォルダを削除し、CodeDeployで使用されているappspec.ymlファイルをdocsのフォルダに置くことが含まれていました。私は、次の前に、インスタンスを再起動に行われた

myproject/ appspec.yml requirements/ docs/ myproject/ manage.py myproject/ __init__.py urls.py wsgi.py settings/ myproject/ __init__.py myproject.py

：

1. がroot /var/www/myproject/myproject/myproject/myprojectからのgunicorn.conf場所を変更。これに

   myproject/ appspec.yml myproject/ requirements/ docs/ myproject/ manage.py myproject/ __init__.py urls.py wsgi.py settings/ myproject/ __init__.py myproject.py

   ：だから私はこのことからつもりですroot /var/www/myproject/myproject/myproject

2. は、私は私のウェブサイトのURLにアクセスしようとnginxのerror.logを見たときにfailed (104: Connection reset by peer) while reading response header from upstreamを見たとき、私は今502 BAD GATEWAYを見ていroot /var/www/myproject/myproject/myproject/myprojectからroot /var/www/myproject/myproject/myproject

からnginx.conf場所を変更しました。

これは明らかに私がプロジェクトディレクトリを混乱させたために起こりました。私は変更が必要な何かを忘れてしまったのですか、最初にディレクトリを変更するのは悪い考えですか？

現在nginx.conf

server { 
    listen 80; 
    server_name www.myproject.co; 
    return 301 http://myproject.co$request_uri; 
}

    listen 80; 
    server_name myproject.co;

    if ($host !~* ^(myproject.co)$) { 
     return 444; 
    }

    location /media/ {

    } 


    location/{ 
     include proxy_params; 
     proxy_pass http://127.0.0.1:8000; 
    } 
} 

現在gunicorn.conf

トレースバックエラー

私はexec /usr/local/bin/gunicorn --workers 3 myproject.wsgi:application --env SECRET_KEY=""を実行すると、私は次のエラーを取得する：

現在、ガンコーンはモジュールを見つけるのに苦労しているようです。

Answer 1

gunicorn.confは、manage.pyというディレクトリを指していませんでした。そこで、私はそれを次のように変更しました：

description "Gunicorn application server handling myproject" 

start on runlevel [2345] 
stop on runlevel [!2345] 

respawn 
setuid ubuntu 
setgid ubuntu 
chdir /var/www/myproject/myproject 

exec /usr/local/bin/gunicorn --workers 3 myproject.wsgi:application --env SECRET_KEY="" 

これが問題を解決しました。Django Docs - How to use Django with Gunicornを参照してください。プロジェクトにはPythonパスが必要です。これを確実にする最も簡単な方法は、manage.pyファイルと同じディレクトリからこのコマンドを実行することです。
