将 mod_wsgi 从 python3.5 更改为 3.6 [英] Change mod_wsgi from python3.5 to 3.6

问题描述

我有一个用于在 apache2 上使用 python3.5 运行的 Flask 应用程序.我现在正在尝试将其更改为在 3.6 上运行(我的代码中有一种仅在 3.6 上支持的类型提示).

我已经安装了 python3.6 的模块，但是当我尝试重新启动 apache 并运行我的应用程序时，它失败了.
运行时

I have a flask app that used to run with python3.5 on apache2. I am now trying to change it to run on 3.6 (i have sone type hinting in my code that is only supported on 3.6).

I have installed the module for python3.6, but when tried to restart apache and run my app, it fails.
When running

mod_wsgi-express module-location

我有python3.5版本

I have the python3.5 version

/usr/local/lib/python3.5/dist-packages/mod_wsgi/server/mod_wsgi-py35.cpython-35m-x86_64-linux-gnu.so

同样的文件也存在于我的服务器上的 python3.6 目录中.
我还更改了我的 $PATH 以运行 python3.6 作为 python 的默认值.
如何告诉 apache 在 python3.6 上运行而不是在 3.5 上运行?

The same file also existis on my server in python3.6 dir.
I also changed my $PATH to run python3.6 as a default for python.
How can I tell apache to run on python3.6 and not on 3.5?

推荐答案

哇！它起作用了！
我卸载了 mod_wsgi (sudo apt get remove libapache2-mod-wsgi).然后，通过pip专门将模块安装到python3.6(python3.6 -m pip install mod_wsgi)，但此时apache仍然运行python3.5.
我添加到apache配置文件(在 ubunutu 16.4 中，该文件位于:/etc/apache2/apache2.conf 和 /usr/local/lib64/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so for RHEL/CentOS 7) 如下:
LoadModule wsgi_module "/usr/local/lib/python3.6/dist-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so"
和
WSGIPythonHome "/usr" 就成功了.
我为这个问题流下了很多眼泪，找到了 apache2.conf 文件等，所以希望这对任何人都有帮助.

WOHA! It's working!
I uninstalled the mod_wsgi (sudo apt get remove libapache2-mod-wsgi). Then, Installed the module via pip specifically to python3.6 (python3.6 -m pip install mod_wsgi), but at this point the apache still ran python3.5.
I added to the apache configuration file (in ubunutu 16.4 the file is located at: /etc/apache2/apache2.conf and /usr/local/lib64/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so for RHEL/CentOS 7) the followings:
LoadModule wsgi_module "/usr/local/lib/python3.6/dist-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so"
and
WSGIPythonHome "/usr" and that did the trick.
I weeped a lot of tears over this issue, finding the apache2.conf file etc, so hopefully this will be helpful to anyone.
