服务Django应用程序时uwsgi分段错误

Question

我正在尝试将Django应用程序从一台服务器迁移到另一台服务器。该应用程序在旧服务器上运行良好。

在新服务器上，使用Django的runserver时，应用程序可以正常运行。

为了在uwsgi下测试Django应用程序，我使用了

uwsgi --http :8000 --module mysite.wsgi

如预期的那样，这将打开django管理页面，但是一旦我尝试登录，uwsgi就会收到如下的分段错误错误。

如果有人可以帮助您理解这意味着什么，以及我将如何解决，将不胜感激。

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（另一个答案的解决方案）
• 从源代码而不是wheel安装psyocpg2

要从源代码安装psyocpg2，您必须卸载上一个并尝试此操作

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

Answer 2

该问题与使用 uWSGI 到 PostgreSQL 的连接有关。

如果可行的话，尝试禁用 SSL

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