标签: mod-wsgi

我正在尝试将Django应用程序部署到Elastic Beanstalk.当我访问页面时,它永远不会加载.日志说:

Script timed out before returning headers: wsgi.py

我可以进入服务器并运行manage.py runserver,然后curl 127.0.0.1:8000从另一个终端运行,这将成功返回页面.所以我认为它必须是Apache配置的一个问题,它被设置为Elastic Beanstalk的一部分.

这里有更多的日志:

[pid 15880] AH01232: suEXEC mechanism enabled (wrapper: /usr/sbin/suexec)
[so:warn] [pid 15880] AH01574: module wsgi_module is already loaded, skipping

我不清楚为什么子解释器API存在以及为什么它在诸如mod_wsgi apache模块之类的模块中使用.它主要用于为同一进程中运行的不同应用程序创建安全沙箱,还是一种允许多线程并发的方法？也许两者？还有其他目的吗？

我有一个来自HTTP标头的字符串,但它已被转义..我可以使用什么功能来解决它​​？

myemail%40gmail.com -> myemail@gmail.com

urllib.unquote()是否可行？

有人可以解释守护进程模式下的apache mod_wsgi和线程模式下的django fastcgi之间的区别.我认为它们都使用线程来实现并发性. 假设我使用nginx作为apache mod_wsgi的前端.

更新:

我正在比较内置fastcgi(./ manage.py方法=线程maxchildren = 15)的django和'daemon'模式下的mod_wsgi(WSGIDaemonProcess示例threads = 15).他们都使用线程并获得GIL,对吗？

UPDATAE 2:

所以,如果它们都相似,那么apache mod_wsgi对fastcgi有什么好处.我看到fastcgi的这些优点:

• 我们不需要apache
• 我们消耗更少的RAM
• 我注意到fastcgi的开销较小

UPDATAE 3:

我现在对nginx + uwsgi很满意.

UPDATAE 4:

我现在对nginx + gunicorn很满意:)

这是这个问题的延续,但它已经偏离,所以我开始了一个新问题.我想使用Python 2.5而不是OS X的默认2.6.我已经为我的终端和诸如此类的东西设置了这个,但是每当apache运行时它给我以下错误输出:

[Thu Jun 23 00:01:42 2011] [warn] Init: Session Cache is not configured [hint: SSLSessionCache]

我已经设置了WSGIPythonPath以匹配sys.path在python shell中提供的内容: …

我想将我的Django项目部署到EC2服务器.我安装了mod_wsgi.

并在django的教程中进行了配置.

我得到以下内容:

Invalid command 'WSGIScriptAlias', perhaps misspelled or defined by a module not included in the server configuration

是什么原因？mod_wsgi安装不正确？

LoadModule wsgi_module     libexec/httpd/mod_wsgi.so
LoadModule alias_module    libexec/httpd/mod_alias.so


WSGIScriptAlias / /usr/local/apache2/htdocs/mysite/mysite/wsgi.py
WSGIPythonPath /usr/local/apache2/htdocs/mysite/mysite


<Directory /path/to/mysite.com/mysite>
<Files wsgi.py>

Allow from all

</Directory>

我正在研究django项目,我收到了这封错误邮件.

为什么会出现这种错误？
怎么解决？

我在AWS上有一个现有的Elastic Beanstalk烧瓶应用程序偶尔不会初始化并给出以下错误:

[Mon Jan 23 10:06:51.550205 2017] [core:error] [pid 7331] [client  127.0.0.1:43790] script timed out before returning headers: application.py

任何想法为什么会这样？最近我将项目requirements.txt改为包括在内pandas==0.19.2.在更改之前,程序将在返回相同错误之前工作几天.更多日志/计划详情:

在我的Ubuntu 16.04服务器上,我有一个Apache conf文件/etc/apache2/sites-enabled/000-default.conf,看起来像这样(缩写):

WSGIApplicationGroup %{GLOBAL}

<VirtualHost *:80>
    ServerName example.com
    WSGIDaemonProcess myprocess user=ubuntu group=ubuntu threads=10 home=/home/ubuntu/myapp
    WSGIProcessGroup myprocess
    ...
</VirtualHost>

它在HTTP模式下工作正常,但是当我运行$ sudo certbot --apache设置HTTPS时,它会失败并显示错误Syntax error on line 7 of /etc/apache2/sites-enabled/000-default.conf: Name duplicates previous WSGI daemon definition. 第7行是以行开头的行WSGIDaemonProcess.

我正在尝试使用virtualenv设置运行WSGI.我的virtualenv一切正常:

(virtualenv)dev:/var/www/app$ which python
/var/www/virtualenv/bin/python
(virtualenv)dev:/var/www/app$ python
Python 2.6.1 (r261:67515, Dec  5 2008, 22:09:34)

而在我的httpd.conf中,我有以下方面的描述在这里:

WSGIPythonHome /var/www/virtualenv
WSGIPythonPath /var/www/virtualenv/lib/python2.6/site-packages

但是当我尝试通过apache加载应用程序时,我收到以下错误:
