Apache+WSGI Django Docker - 运行 Django 时出现错误:RuntimeError: populate() isn't reentrant

  • 772

有这样一个Apache + WSGI Django Docker 的组合。当容器启动时,默认的 Apache 页面正常打开。但是,当您使用 Django 应用程序访问某些页面时,它无法打开,并且日志中出现错误:This is a log in the container

root@828dcbc18f43:/# tail -f /var/log/apache2/error.log
mod_wsgi (pid=9): Failed to exec Python script file '/home/test/app1/backend/otu_it/wsgi.py'.
mod_wsgi (pid=9): Exception occurred processing WSGI script '/home/test/app1/backend/otu_it/wsgi.py'.
Traceback (most recent call last):
   File "/home/test/app1/backend/otu_it/wsgi.py", line 20, in <module>
     application = get_wsgi_application()
   File "/home/test/app1/venv/lib/python3.8/site-packages/django/core/wsgi.py", line 12, in get_wsgi_application
     django.setup(set_prefix=False)
   File "/home/test/app1/venv/lib/python3.8/site-packages/django/__init__.py", line 24, in setup
     apps.populate(settings.INSTALLED_APPS)
   File "/home/test/app1/venv/lib/python3.8/site-packages/django/apps/registry.py", line 83, in populate
     raise RuntimeError("populate() isn't reentrant")
 RuntimeError: populate() isn't reentrant

这是 Django 应用程序的 Apache 配置文件:

        WSGIPythonHome /home/test/app1/venv
        WSGIPythonPath /home/test/app1/backend


<VirtualHost *:80/api/user>
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin webmaster@localhost
        DocumentRoot /home/test/app1/backend/
        WSGIScriptAlias / /home/test/app1/backend/otu_it/wsgi.py

#                Allow from all
        </Directory>

        #LogLevel info ssl:warn

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

        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

        SSLEngine on

        ServerAdmin webmaster@localhost
        DocumentRoot /home/test/app1/backend/
        WSGIScriptAlias / /home/test/app1/backend/otu_it/wsgi.py
#        WSGIPythonHome /home/test/app1/venv
#        WSGIPythonPath /home/test/app1/backend

        <Directory /home/test/app1/backend/otu_it/>
                <Files wsgi.py>
                        Require all granted
                </Files>
#                Order allow,deny
#                Allow from all
        </Directory>

        #LogLevel info ssl:warn

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

        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

也许我错误地连接了 Django 的虚拟环境。我已经尝试了很多 - 没有任何帮助。可能是什么问题呢?PS - 在容器之外,一切都可以使用这些配置,没有问题。

    经过更仔细的研究日志后,我发现了这些条目:

        mod_wsgi (pid=10): Failed to exec Python script file '/home/test/app1/backend/otu_it/wsgi.py'.
    mod_wsgi (pid=10): Exception occurred processing WSGI script '/home/test/app1/backend/otu_it/wsgi.py'.
    Traceback (most recent call last):
       File "/home/test/app1/venv/lib/python3.8/site-packages/django/db/backends/postgresql/base.py", line 25, in <module>
         import psycopg as Database
       File "/home/test/app1/venv/lib/python3.8/site-packages/psycopg/__init__.py", line 9, in <module>
         from . import pq  # noqa: F401 import early to stabilize side effects
       File "/home/test/app1/venv/lib/python3.8/site-packages/psycopg/pq/__init__.py", line 114, in <module>
         import_from_libpq()
       File "/home/test/app1/venv/lib/python3.8/site-packages/psycopg/pq/__init__.py", line 106, in import_from_libpq
         raise ImportError(
     ImportError: no pq wrapper available.
     Attempts made:
     - couldn't import psycopg 'c' implementation: No module named 'psycopg_c'
     - couldn't import psycopg 'binary' implementation: No module named 'psycopg_binary'
     - couldn't import psycopg 'python' implementation: libpq library not found
    

    接下来我安装了附加模块

    pip install psycopg2
    
    pip install psycopg2-binary
    

    一切顺利。
