我现在正在尝试通过这个页面的步骤来安装mod_wsgi，链接是https://github.com/GrahamDumpleton/mod_wsgi（看起来是官方页面）。

我用命令pip install mod_wsgi安装完后，输入命令mod_wsgi-express start-server来检查它是否能运行。

结果似乎没有运行，我遇到了一个错误：

root@vpsxxxx:/# mod_wsgi-express start-server
Server URL      : http://localhost:8000/
Server Root     : /tmp/mod_wsgi-localhost:8000:0
Server Conf     : /tmp/mod_wsgi-localhost:8000:0/httpd.conf
Error Log       : /tmp/mod_wsgi-localhost:8000:0/error_log
AH00534: apache2: Configuration error: More than one MPM loaded.

如你所见，我是以root身份运行的，但如果我用mod_wsgi-express start-server wsgi.py --port=80 --user www-data --group www-data命令，还是会出现同样的错误。

有没有什么想法？

编辑： 可能在安装过程中出现了问题：

Graham Dumpleton刚刚更新了这个代码库，并解决了这个问题，所以请考虑更新你的python mod_wsgi模块，这样就能修复你的问题。

在后台运行mod-wsgi模块的python代码试图添加多个MPM，但实际上已经添加了一个，结果没有按预期跳出循环。

这里是相关的代码

def _mpm_module_defines(modules_directory):
    result = []
    workers = ['event', 'worker', 'prefork']
    for name in workers:
        if os.path.exists(os.path.join(modules_directory,
                'mod_mpm_%s.so' % name)):
            result.append('-DWSGI_MPM_%s_MODULE' % name.upper())
    return result

这段代码没有考虑到系统上安装了多个Apache模块（比如event、worker和prefork）的情况。现在代码在添加后增加了一个“break”，这样就能正确跳出循环了。
