使用 mod_wsgi 部署 django3 项目

如何解决使用 mod_wsgi 部署 django3 项目

我正在尝试使用 Apache mod_wsgi 发布我的 django 项目。我在 virtualenv 中创建了一个名为 sampleapp 的简单 django3 项目。然后，我将我的 /etc/apache2/sites-enabled/000-default.conf 文件配置如下

<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html

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

WsgiDaemonProcess sampleapp python-home=/var/www/html/sampleapp/env python-path=/var/www/html/sampleapp:/var/www/html/sampleapp/env/lib/python3.7/site-packages
WsgiProcessGroup sampleapp
WsgiScriptAlias /sampleapp /var/www/html/sampleapp/sampleapp/wsgi.py process-group=sampleapp

</VirtualHost>

虽然我的virtualenv 的python 版本是3.7，但mod_wsgi 使用的是系统的python 版本(3.5)，所以它看不到我的virtualenv 并且不使用它的python 版本。我的apache错误日志如下：

如何配置 mod_wsgi 以使用我的 venv 的 python 版本？或者我的错在哪里？感谢您的回答。

解决方法

因此 mod_wsgi 被编译为特定版本的 Python for Apache。你不能让它运行不同版本的python。您可以将该 mod_wsgi 重建为正确的版本，也可以更改虚拟环境。这会删除 virtualenv 包装器但保留项目文件。

我认为“更改 virtualenv”会更容易。

rmvirtualenv env-name
mkvirtualenv -p python3.5 env-name
setvirtualenvproject env-name

当您使用“mkvirtualenv”时，请使用 -r 标记作为 requirements.txt

或者重建 mod_wsgi：
