一条特定路线的uwsgi分段故障 [英] uwsgi segmentation fault for one specific route
本文介绍了一条特定路线的uwsgi分段故障的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我的django应用程序在本地可以正常工作，但是当我部署它时，它面临着一条特定路由的uswgi seg错误.其他所有路由均正常运行.这里的视图:
My django apps works correctly locally, but when I deployed it facing a uswgi seg fault for one specific route. Every others routes works correctly. Here the 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 conf文件:
uWsgi conf file:
[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:

*** end of backtrace ***
DAMN ! worker 1 (pid: 4668) died :( trying respawn ...
Respawned uWSGI worker 1 (new pid: 4709)
我正在使用django和psycopg2的最新版本.
I am using latest version of django and psycopg2.
推荐答案
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.
This error occurs when uwsgi and psycopg are compiled against two different openssl versions. You have two solution.
-
禁用django数据库配置的ssl
disable ssl of django database configuration
# Database
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'mydb',
'USER': 'myuser',
'PASSWORD': 'mypassword',
'HOST': 'localhost',
'PORT': '',
'OPTIONS': {
'sslmode': 'disable'
}
}
}
要从源代码安装psyocpg2，您必须卸载上一个并尝试此操作
to install psyocpg2 from source you have to uninstall previous one and try this
pip uninstall psycopg2
pip install --no-binary :all: psycopg2
