django - 一条特定路由的 uwsgi 段错误

Question

我的 django 应用程序在本地工作正常，但当我部署它时，它面临一条特定路线的 uswgi seg 错误。其他所有路线均正常工作。这是 View :

def bunny(request):
   """
    Filter crawler, bot and real user
    :param request:
    :return: serve rendered page to crawler / SPA to user
    """
   ......some other codes ....
   path = request.get_full_path_info()
   if path.startswith('/news_paper'):   # <<-- seg fault for this routes only in production server
        news_paper = utils(unquote(path[12:]))
        if news_paper[1] == 0:  # if news paper is not found return default list
            return render(request, 'site_list.html')
        news = News.objects.filter(news_paper=news_paper[1]).order_by('-created_at')[:15]
        return render(request, 'news.html', {'news': news, 'title': news_paper[0]})
    elif path == '/about/':
        return render(request, 'about.html')
    else:
        return render(request, 'site_list.html')

uWsgi 配置文件:

[uwsgi]
chdir=/home/..
home = /home/../.env
module=xyz.wsgi
master=True
process = 5
pidfile=/run/xyz.pid
socket= /run/xyz.sock
stats=/tmp/xyz.stat
vacuum=True
max-requests=500
logto = /home/../logs/xyz.log
log-maxsize = 200480
uid = prism
gid = www-data
die-on-term = true

chmod-socket = 666
chown-socket = www-data

和日志文件:

DAMN ! worker 1 (pid: 4668) died :( trying respawn ...
Respawned uWSGI worker 1 (new pid: 4709)

我正在使用最新版本的 django 和 psycopg2。

Answer 1

当针对两个不同的 openssl 版本编译 uwsgi 和 psycopg 时，会发生此错误。您有两种解决方案。

• 禁用 django 数据库配置的 ssl

  # Database
  DATABASES = {
      'default': {
          'ENGINE': 'django.db.backends.postgresql',
          'NAME': 'mydb',
          'USER': 'myuser',
          'PASSWORD': 'mypassword',
          'HOST': 'localhost',
          'PORT': '',
          'OPTIONS': {
              'sslmode': 'disable'
          }
      }
  }
  

• 从源代码而不是wheel安装psyocpg2

要从源代码安装 psyocpg2，您必须卸载以前的版本并尝试此

pip uninstall psycopg2
pip install --no-binary :all: psycopg2
