的Python - Django的Manage.py執行syncdb失敗？

Question

所以，我使用OpenShift Django的快速啓動，與MySQL 5.1和phpMyAdmin安裝4.0。我已經建立了一個數據庫，並且遵循了一個教程來解決這個錯誤。當我做「蟒蛇manage.py執行syncdb」，以下出現：

python manage.py syncdb

任何人有任何想法是怎麼回事？我試圖創建一個新的項目，並按照相同的指示，但結果是一樣的。

只是爲了精確@ sdolan的答案：確實，你必須使用正確的OpenShift的MySQL指標的影響。一個簡單的方法來做到這一點是使用OpenShift ENV變量，像這樣的（這是我的應用程序的settings模塊）：

# a setting to determine whether we are running on OpenShift 
ON_OPENSHIFT = False 
if os.environ.has_key('OPENSHIFT_REPO_DIR'): 
    ON_OPENSHIFT = True 

if ON_OPENSHIFT: 
    # os.environ['OPENSHIFT_MYSQL_DB_*'] variables can be used with databases created 
    # with rhc cartridge add (see /README in this git repo) 
    DATABASES = { 
     'default': { 
      'ENGINE': 'django.db.backends.mysql', 
      'NAME':  'myapp',    
      'USER':  os.environ['OPENSHIFT_MYSQL_DB_USERNAME'],  
      'PASSWORD': os.environ['OPENSHIFT_MYSQL_DB_PASSWORD'], 
      'HOST':  os.environ['OPENSHIFT_MYSQL_DB_HOST'],   
      'PORT':  os.environ['OPENSHIFT_MYSQL_DB_PORT'],   
     } 
    } 
else: 
    DATABASES = { 
     'default': { 
      'ENGINE': 'django.db.backends.sqlite3',   
      'NAME':  os.path.join(PROJECT_DIR, 'sqlite3.db'), 
      'USER':  '',          
      'PASSWORD': '',          
      'HOST':  '',          
      'PORT':  '',          
     } 
    }
