如果Apache2使用虚拟主机设置文件@〜/ public_html / idm.wsgi，那么系统认为用户在尝试编写日志文件log / django.osqa.log？
为什么我的Django应用程序不能写入其日志文件？
答案 0 :(得分：17)
Apache可能作为apache用户运行，这意味着它没有对日志文件的写访问权。它启动很好，因为它只需要读取wsgi文件，该文件具有所有用户的读取权限。 chmod a+w django.osqa.log或chown <apache-user> django.osqa.log。
注意：首选方法是chown文件。
注意2：这是依赖于发行版的，但由于它看起来像Ubuntu-y，因此apache用户将是www-data。
