Question

我试图让用Django编写的生产Web门户工作，但是我遇到了一些问题。该页面将解析为登录页面，身份验证将起作用并带您进入第一页。但是，没有数据库数据存在，此外，如果我尝试切换页面，它将给我502错误。

当我使用Django Web服务器时，一切正常。我认为这只是uWsgi设置的一个问题。这是我第一次使用django将服务器发布到生产中，所以我为我缺乏知识而道歉。

This is the error that triggers inside the log file upon switching pages
2014/10/22 17:19:03 [error] 21424#0: *1 upstream prematurely closed connection while reading response header from upstream, client: 172.17.1.16, ser$

我读过它是因为需要设置uWsgi文件：

plugin = Python

设置的

：

我的项目/应用结构

/var/www/dashboard/holon   # this is the project roon where I can run manage.py test server and everything will work.

/var/www/dashboard/holon/holon  #this is the project settings directory

/var/www/dashboard/holon/portal/ #this is the app directory

/var/www/dashboard/conf #this is where the Nginx and uWsgi config files live

uWsgi config：

[uwsgi]
# variables
projectname = holon
projectdomain = enki.co
base = /var/www/dashboard

# config
plugin = python
master = true
protocol = uwsgi
env = DJANGO_SETTINGS_MODULE=%(projectname).settings
pythonpath = %(base)/%(projectname)
module = %(projectname).wsgi
socket = 127.0.0.1:8001
logto = %(base)/logs/uwsgi.log
#below line runs it as a daemon in background
daemonize = /var/log/uwsgi/holon_dashboard.log

Nginx配置：

server {
    listen 80;
    server_name dashboard.enki.co;
    root /var/www/dashboard/holon;
    access_log /var/www/dashboard/logs/access.log;
    error_log /var/www/dashboard/logs/error.log;

    location /static/ { # STATIC_URL
        alias /var/www/dashboard/holon/portal/static/; # STATIC_ROOT
        expires 30d;
    }

    location / {
        include uwsgi_params;
        uwsgi_pass 127.0.0.1:8001;
    }
}

Answer 1

我有类似的问题。一切都运行良好的django运行服务器，但在uwsgi我有一个数据库访问错误。我的解决方案是确保正确配置pythonpath。确保它已配置。

尝试将其更改为硬编码链接，而不是：

pythonpath =％（base）/％（projectname）

Django + uWsgi + Nginx没有数据库数据，加上502页面更改错误
