如何在 Apache2.2 上正确部署带有 mod_wsgi 的烧瓶应用程序

Question

我一直在尝试在 Ubuntu Web 服务器上部署我的应用程序，但收效甚微。我定义的虚拟主机文件是：

    #WSGIRestrictStdout Off
    <VirtualHost *:80>
    ServerName demo.engineerinme.com
    WSGIDaemonProcess fedoracollege  user=engineer group=www-data threads=5
    WSGIScriptAlias / /home/engineer/fedora-college/fedora_college.wsgi
    <Directory /home/engineer/fedora-college/>
                    WSGIProcessGroup fedoracollege
                    WSGIApplicationGroup %{GLOBAL}
                    WSGIScriptReloading On
                    Options All ExecCGI Indexes FollowSymLinks
                    Order allow,deny
                    Allow from all

    </Directory>

    Alias /static /home/engineer/fedora-college/fedora_college/static
    <Directory /home/engineer/fedora-college/fedora_college/static/>
                    Order allow,deny
                    Allow from all
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    LogLevel debug
    CustomLog ${APACHE_LOG_DIR}/access.log combined
    </VirtualHost>

我面临的问题是，静态内容工作正常，但烧瓶应用程序没有运行。像http://demo.engineerinme.com 一样显示未找到错误。但http://demo.engineerinme.com/static 有效。

部署的wsgi脚本是：

#!/usr/bin/python
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/home/engineer/fedora-college/")

from fedora_college import app as application
application.secret_key = 'Add your secret key'

错误日志：

[Mon Jun 30 23:01:31 2014] [debug] mod_deflate.c(615): [client 59.177.114.30] Zlib: Compressed 233 to 180 : URL /

我遇到了这个问题，同样的解决方案是在虚拟主机文件中。

有时 Apache 日志也会显示此错误：

[Mon Oct 17 15:24:24 2011] [error] [client 90.181.85.69] (13)Permission denied: mod_wsgi (pid=21805): Unable to connect to WSGI daemon process 'fedoracollege' on '/var/run/apache2/wsgi.16282.4.1.sock' after multiple attempts.

此问题已在此处正确解释。我刚刚重建了wsgi_mod。

https://serverfault.com/questions/322131/wsgi-says-permissions-denied-on-my-ubuntu-server-no-wsgisocketprefix-setting

另外，将虚拟主机文件重写为这种格式。 （去掉virtualhost和direcory标签）

Alias /static  /home/engineer/fedora-college/fedora_college/static
WSGIDaemonProcess fedoracollege user=engineer group=www-data threads=5
#WSGIDaemonProcess fedoracollege maximum-requests=1000 display-name=fedora-college processes=4 threads=4
WSGISocketPrefix /var/run/wsgi
WSGIRestrictStdout Off
WSGIRestrictSignal Off
WSGIPythonOptimize 1
WSGIScriptAlias /  /home/engineer/fedora-college/fedora_college.wsgi
<Location />
    WSGIProcessGroup fedoracollege
</Location>


ErrorLog ${APACHE_LOG_DIR}/error.log
LogLevel debug
CustomLog ${APACHE_LOG_DIR}/access.log combined

另外，设置

application = True 

用于正确的错误报告。
