服务器部署_阿里云服务器部署后显示Internal Server Error

问题描述:

Internal Server Error

 原因分析：

重新查看nginx和uwsgi配置，再次重启nginx和uwsgi，发现还是一样的状况，但是访问项目的静态文件时成功的，查看uwsgi中设置的log文件

Traceback (most recent call last):
  File "./dailyfresh/wsgi.py", line 16, in <module>
    application = get_wsgi_application()
  File "/zt_dailyfresh/dailyfresh_env/lib/python3.6/site-packages/django/core/wsgi.py", line 12, in get_wsgi_application
    django.setup(set_prefix=False)
  File "/zt_dailyfresh/dailyfresh_env/lib/python3.6/site-packages/django/__init__.py", line 19, in setup
    configure_logging(settings.LOGGING_CONFIG, settings.LOGGING)
  File "/zt_dailyfresh/dailyfresh_env/lib/python3.6/site-packages/django/conf/__init__.py", line 79, in __getattr__
    self._setup(name)
  File "/zt_dailyfresh/dailyfresh_env/lib/python3.6/site-packages/django/conf/__init__.py", line 66, in _setup
    self._wrapped = Settings(settings_module)
  File "/zt_dailyfresh/dailyfresh_env/lib/python3.6/site-packages/django/conf/__init__.py", line 157, in __init__
    mod = importlib.import_module(self.SETTINGS_MODULE)
  File "/usr/lib/python3.6/importlib/__init__.py", line 126, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
ModuleNotFoundError: No module named 'settings_production'
unable to load app 0 (mountpoint='') (callable not found or import error)

 找到原因。项目的wsgi.py文件中settings引用错误，修改后重新启动uwsgi，遇到这个问题，不多说找到代码直接注掉

 load_backend
    return import_module('%s.base' % backend_name)
  File "/usr/lib/python3.6/importlib/__init__.py", line 126, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "/zt_dailyfresh/dailyfresh_env/lib/python3.6/site-packages/django/db/backends/mysql/base.py", line 36, in <module>
    raise ImproperlyConfigured('mysqlclient 1.3.13 or newer is required; you have %s.' % Database.__version__)
django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.

注掉后重启uwsgi（还有个地方将decode修改为encode的），

查看uwsgi的日志文件，明白了，当时使用了jieba分词器，修改了haystack底层代码，额外建了一个文件并没有上传到服务器上。

  File "/zt_dailyfresh/dailyfresh_env/lib/python3.6/site-packages/haystack/query.py", line 29, in __init__
    self._determine_backend()
  File "/zt_dailyfresh/dailyfresh_env/lib/python3.6/site-packages/haystack/query.py", line 62, in _determine_backend
    self.query = connections[backend_alias].get_query()
  File "/zt_dailyfresh/dailyfresh_env/lib/python3.6/site-packages/haystack/utils/loading.py", line 109, in __getitem__
    self.thread_local.connections[key] = load_backend(self.connections_info[key]['ENGINE'])(using=key)
  File "/zt_dailyfresh/dailyfresh_env/lib/python3.6/site-packages/haystack/utils/loading.py", line 60, in load_backend
    return import_class(full_backend_path)
  File "/zt_dailyfresh/dailyfresh_env/lib/python3.6/site-packages/haystack/utils/loading.py", line 27, in import_class
    module_itself = importlib.import_module(module_path)
  File "/usr/lib/python3.6/importlib/__init__.py", line 126, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
ModuleNotFoundError: No module named 'haystack.backends.whoosh_cn_backend'

 上传相关文件后，访问服务器ip

还有个问题，我的数据库还没有建表，建表后。

 decode修改为encode

\lib\site-packages\django\db\backends\mysql\operations.py”, line 146, in last_executed_query 　　
query = query.decode(errors=‘replace’) 　　
AttributeError: ‘str’ object has no attribute ‘decode’ 

 成功。
