mod_wsgi - 致命的 Python 错误:initfsencoding:无法加载文件系统编解码器 [英] mod_wsgi - Fatal Python error: initfsencoding: unable to load the file system codec

问题描述

使用 Red Hat、apache 2.4.6、worker mpm、mod_wsgi 4.6.5 和 Python 3.7 启动 httpd 时出现上述错误，并且:

Using Red Hat, apache 2.4.6, worker mpm, mod_wsgi 4.6.5, and Python 3.7 When I start httpd I get the above error and:

ModuleNotFoundError: 没有名为encodings"的模块

在 httpd error_log 中.

In the httpd error_log.

我正在使用从我的主目录下的源代码安装的 python 创建的 python 虚拟环境.我使用 --with-python= 选项从源代码安装了 mod_wsgi，指向我的虚拟环境中的 python 二进制文件，然后我将 mod_wsgi.so 文件复制到我的 apache 模块目录中作为 mod_wsgi37.so

I'm using a python virtual environment created from a python installed from source under my home directory. I installed mod_wsgi from source using --with-python= option pointing to the python binary in my virtual environment, then I copied the mod_wsgi.so file into my apache modules directory as mod_wsgi37.so

我在这个文件上运行了 ldd，并有一个 .conf 文件将它加载到 httpd 中，如下所示:

I ran ldd on this file, and have a .conf file loading it into httpd like this:

LoadFile/home/myUser/pythonbuild/lib/libpython3.7m.so.1.0LoadModule wsgi_module modules/mod_wsgi37.so

然后在我的 VirtualHost 中:

Then within my VirtualHost I have:

WSGIDaemonProcess wsgi group=www threads=12 processes=2 python-path=/var/www/wsgi-scripts python-home=/var/www/wsgi-scripts/wsgi_env3WSGIProcessGroup wsgiWSGIScriptAlias/test/var/www/wsgi-scripts/test.py

来自我的虚拟环境:

sys.prefix:'/var/www/wsgi-scripts/wsgi_env3'

sys.prefix:'/var/www/wsgi-scripts/wsgi_env3'

sys.real_prefix:'/home/myUser/pythonbuild'

sys.real_prefix:'/home/myUser/pythonbuild'

当我切换到系统安装的 mod_wsgi/python 组合(从 WSGIDaemonProcess 中删除 python-home 行，并更改 .conf 文件以加载原始 mod_wsgi.so)时，它工作正常.似乎某些路径变量没有正确设置.有没有另一种方法来设置我缺少的 PYTHONHOME 之类的变量?如何修复我的安装?

When I switch to the system-installed mod_wsgi/python combo (remove python-home line from WSGIDaemonProcess, and change the .conf file to load the original mod_wsgi.so) it works fine. It seems like some path variables aren't getting set properly. Is there another way to set variables like PYTHONHOME that I'm missing? How can I fix my install?

推荐答案

我有一个非常相似的问题，我发现我手动指定的 LoadModule wsgi_module "/path_to_conda/" 被忽略，因为之前的 apache-wide wsgi mod 正在加载.您可以检查 /etc/apache2/mods-enabled 中是否存在 wsgi.*.

I had a very similar issue and I found that my manually specified LoadModule wsgi_module "/path_to_conda/" was being ignored because the previously apache-wide wsgi mod was being loaded. You can check if wsgi.* is present in /etc/apache2/mods-enabled.

如果是这种情况，请考虑使用 a2dismod wsgi 禁用加载错误 python 的 apache wsgi.

If that is the case, consider a2dismod wsgi to disable the apache wsgi that loads the wrong python.
