Mac : LoadModule wsgi_module不像docs中提到的那样工作

Question

由于Mac的安全原因，我将apache从2.4.25升级到2.4.29。还通过pip安装了mod_wsgi。

现在在重新启动apache服务器时面临困难！

我按照mod_wsgi 文档运行了这个命令，

> mod_wsgi-express module-config
LoadModule wsgi_module "/Library/Python/2.7/site-packages/mod_wsgi/server/mod_wsgi-py27.so"
WSGIPythonHome "/System/Library/Frameworks/Python.framework/Versions/2.7"

复制apache.conf文件中的上述两行并尝试启动apache服务器，但得到了以下错误：

> sudo apachectl start
/usr/local/apache/bin/apachectl: line 79: 51863 Illegal instruction: 4  $HTTPD -k $ARGV

任何帮助都将不胜感激。谢谢!

根据格雷厄姆的回答，编辑：

# I upgraded the mod_wsgi

Successfully installed mod-wsgi-4.5.21

但当我试着：

> mod_wsgi-express start-server
Traceback (most recent call last):
  File "/Library/WebServer/Documents/DSFENV/bin/mod_wsgi-express", line 11, in <module>

    raise ValueError, 'unknown locale: %s' % localename
ValueError: unknown locale: UTF-8

得到上面的错误。此外，我还安装了Apache2.4.29以下的博客

第二版I已经解决了ValueError: unknown locale: UTF-8，现在mod_wsgi-express start-server的输出显示：

> mod_wsgi-express start-server

但是，当我尝试进行配置测试时，仍然会显示相同的错误：

> sudo apachectl configtest
/usr/local/apache/bin/apachectl: line 79: 53944 Illegal instruction: 4  $HTTPD -t

xcode版本：

> xcodebuild -version
Xcode 8.3.2
Build version 8E2002

第三版按注释编辑：

> /usr/local/apache/bin/httpd
Illegal instruction: 4

> /Library/Python/2.7/site-packages/mod_wsgi/server/mod_wsgi-py27.so
-bash: /Library/Python/2.7/site-packages/mod_wsgi/server/mod_wsgi-py27.so: cannot execute binary file

'2.7.10 (default, Feb  7 2017, 00:08:15) \n[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.34)]'

我跟随这个博客安装Apache2.4.29：http://mac-dev-env.patrickbougie.com/apache/

-带有-ssl选项，因为我们需要为网站进行https。

请告诉我如何前进。

如果您已经以某种方式更新了Apache安装，那么通常来自较早版本的mod_wsgi.so二进制文件仍然可以工作，因为Apache在补丁级别的更新中维护ABI的兼容性。

如果它不能工作，那么您可能需要重新构建mod_wsgi。如果没有更新版本的mod_wsgi，则需要强制进行完全重新构建，以确保不使用来自pip缓存的缓存二进制文件。

pip install --upgrade --no-cache-dir mod_wsgi

然而，下一个问题是，如果你升级到Xcode 9.1，苹果已经彻底删除了apxs，这意味着我以前的苹果故障解决方案不再起作用。在这种情况下，您需要确保正在安装mod_wsgi 4.5.21或更高版本。该版本只是刚刚发布的补丁，以适应Xcode 9.1

因此，请尝试上面的pip命令，并通过运行以下命令确保mod_wsgi-express仍然工作：

mod_wsgi-express start-server

然后再次运行，验证要在Apache配置中使用的配置片段：

mod_wsgi-express module-config

如果仍然存在主要Apache的问题，那么请确保完全停止Apache，然后启动，而不仅仅是重新启动。告诉我这一切是怎么回事。

以上假设您正在使用Apple提供的Apache对Xcode 9.1的评论。你好像在用自己的Apache，也许是自制的。还是尝试同样的方法。

格雷厄姆建议：

pip install --upgrade --no-cache-dir mod_wsgi

升级到mod_wsgi 4.5.22成功了。
