httpd 与 django3 与 python3.6 在 Centos7

Question

我们正在尝试使用 httpd 运行 django3（Centos7 上的 python3.6）。

当我通过 HTTPD 运行它时出现以下错误。

我在 /etc/httpd/conf.d 中的 django.conf 文件如下：

Alias /static /srv/static
<Directory /srv/static>
Require all granted
</Directory>

<Directory /srv/django/django>
   <Files wsgi.py>
       Require all granted
   </Files>
</Directory>

WSGIDaemonProcess django python-path=/srv/django:/usr/local/lib/python3.6/site-packages
WSGIProcessGroup django
WSGIApplicationGroup %{GLOBAL}
WSGIScriptAlias / /srv/django/django/wsgi.py

和我的 wsgi.py 如下：

import os
import sys
from django.core.wsgi import get_wsgi_application
os.chdir('/srv/django/')
sys.path.append('/srv/django/')
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'django.settings')
application=get_wsgi_application()

我们安装了以下软件包

python3-devel.x86_64 
rh-python36-mod_wsgi.x86_64
yum install httpd-devel

django 项目本身工作正常

100.10.100.10 (/srv/django/)-1003> python3 manage.py runserver

Django version 3.1.5, using settings 'django.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

我错过了什么？

Answer 1

我不太熟悉 Apache Httpd 与 WSGI 的工作情况，但是如果您单独启动 Django 并且您只是想快速运行反向代理，您可以执行以下操作：

<VirtualHost *:80>
    ServerAdmin admin@localhost
    ProxyRequests off
    DocumentRoot /var/www
    # SSLProxyEngine on
    # ProxyPreserveHost On

    ServerName www.yoursite.net

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel error

    <Location />
        ProxyPass http://www.yourwebsite.net/
        ProxyPassReverse http://localhost:8080/
        Order allow,deny
        Allow from all
    </Location>

</VirtualHost>

就错误而言，看起来 wsgi.py 找不到django.settings意味着django目录和settings模块不在当前路径中。
