第一次尝试在我的金字塔应用程序中使用 mod_wsgi,但是ImportError: No module named deploy当我尝试访问该站点时,我一直得到一个

在我的/etc/apache2/sites-available/domain.com

<VirtualHost *:80>  
    ServerName domain.com
    ServerAlias www.domain.com
    ServerAdmin admin@domain.com
    DocumentRoot /data/app
    ErrorLog /data/app/apache_error.log

    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    WSGIDaemonProcess pyramid user=www-data group=www-data \
        processes=2 threads=4 \
        python-path=/data/app/lib/python2.6/site-packages/
    WSGIScriptAlias / /data/app/pyramid.wsgi

    <Directory /data/app>
        WSGIProcessGroup pyramid
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

/data/app/pyramid.wsgi

venv = '/data/app/bin/activate_this.py'
execfile(venv, dict(__file__=venv))

ALLDIRS = ['/data/app/lib/python2.6/site-packages']

import sys, site, os

site.addsitedir('/data/app/lib/python2.6/site-packages')

sys.path.append('/data/app/app')
os.environ['PYTHON_EGG_CACHE'] = '/data/app/python-eggs'

from pyramid.paster import get_app, setup_logging
ini_path = '/data/app/app/development.ini'
setup_logging(ini_path)
application = get_app(ini_path, 'main')

当我尝试domain.com在浏览器中访问时,The server encountered an internal error or misconfiguration and was unable to complete your request出现错误。这是我的错误日志的打印结果

请注意,test第一行的打印是我print 'test'在顶部手动添加的,/data/app/lib/python2.6/site-packages/pyramid-1.4-py2.6.egg/pyramid/paster.py以确保它是从我期望的文件中加载的...

现在如果我从 pserve 启动应用程序

$ /bin/pserve app/development.ini --reload

应用启动成功,控制台日志如下

test
Starting subprocess with file monitor
test
Starting server in PID 9132.
serving on http://0.0.0.0:6543

我也试过直接进入python导入paster.py,也没问题

$ cd /data/app/lib/python2.6/site-packages/pyramid-1.4-py2.6.egg/pyramid/
$ /data/app/bin/python
Python 2.6.5 (r265:79063, Oct  1 2012, 22:04:36)

>>> import pyramid.paster as p
test
>>> print p.__file__
/data/app/lib/python2.6/site-packages/pyramid-1.4-py2.6.egg/pyramid/paster.pyc
>>>

权限也应该没问题

$ ls /data/app -l
-rw-rw-r-- 1 root www-data 4148 2013-04-22 21:06 apache_error.log
drwxrwsr-x 4 root www-data 4096 2013-04-22 12:05 app

我错过了什么?谢谢!

编辑 www-data也是正确的用户

$ ps aux | grep apache2
root      2599  0.0  1.4 185200 14552 ?        Ss   10:00   0:02 /usr/sbin/apache2 -k start

根据格雷厄姆的建议进行编辑print 'test',我用paste.py

import paste as p
print p.__path__

通过 apache 访问站点时的打印输出是/usr/local/lib/python2.6/dist-packages/paste,而不是 virtualenv。我已经添加了所有我可以在线很好地指向我的 virtualenvpyramid.wsgi以及pythonpathapache 配置文件中的示例,但显然我仍然没有做对。我还能在哪里尝试?

终于解决了。从控制台日志很明显,我的主要 python 安装安装了/usr/local/lib一个未定义处理程序的paste模块deploy

RedBaron 的评论设置WSGIPythonHome有效,但问题是我有多个应用程序,所以我不能只WSGIPythonHome全局指向特定应用程序的 virtualenv。

无论如何,我再次浏览mod_wsgi了 virtualenv 上的文档(https://code.google.com/p/modwsgi/wiki/VirtualEnvironments#Baseline_Environment)并看到它WSGIPythonHome应该指向“处女环境”。字面上地

$ virtualenv --no-site-packages BASELINE

然后指向WSGIPythonHome

WSGIPythonHome /usr/local/pythonenv/BASELINE

并指向WSGIDaemonProcess我的应用程序的特定 virtualenv(我在一开始就已经这样做了)

教训:多注意文档...


最后,我的pyramid.wsgi可以大大简化为只有以下

import os
os.environ['PYTHON_EGG_CACHE'] = '/data/app/python-eggs'

from pyramid.paster import get_app, setup_logging
ini_path = '/data/app/app/development.ini'
setup_logging(ini_path)
application = get_app(ini_path, 'main')

在我的情况下,在虚拟环境中重新安装 PasteDeploy 解决了这个问题,但不知道为什么。

该错误表明没有安装 PasteDeploy 包。
