Question

我正在尝试将金字塔应用推广到生产网站。

截至目前，我已经创建了应用程序放置在public_html中的env文件，如下所示：

    [~/env] $

所以我输入了

    $ ../bin/pserve production.ini,

但是，当我访问www.mydomain.com时，它仍然显示index.html。我该如何解决这个问题？

我使用的是CentOS 64bit + Apache + mod_wsgi。

设置如下：

    Apache/2.2.24 (Unix) 
    mod_ssl/2.2.24 
    OpenSSL/1.0.0-fips 
    mod_wsgi/3.3 
    Python/2.6.6 
    mod_auth_passthrough/2.1 
    mod_bwlimited/1.4 
    FrontPage/5.0.2.2635 configured -- resuming normal operations

在我的production.ini文件中，如下所示

    [app:main]
    use = egg:ECommerce
    reload_templates = false
    debug_authorization = false
    debug_notfound = false
    debug_routematch = false
    debug_templates = false
    default_locale_name = en
    mongodb.url = mongodb://my.ip.address
    mongodb.db_name = mycart_demo

    [filter:weberror]
    use = egg:WebError#error_catcher
    debug = false
    ;error_log = 
    ;show_exceptions_in_wsgi_errors = true
    ;smtp_server = localhost
    ;error_email = janitor@example.com
    ;smtp_username = janitor
    ;smtp_password = "janitor's password"
    ;from_address = paste@localhost
    ;error_subject_prefix = "Pyramid Error"
    ;smtp_use_tls =
    ;error_message =

    #[pipeline:main]
    #pipeline =
    #    weberror
    #    ECommerce

    [server:main]
    use = egg:waitress#main
    host = 0.0.0.0
    port = 8080

    # Begin logging configuration

    [loggers]
    keys = root, ecommerce

    [handlers]
    keys = console

    [formatters]
    keys = generic

    [logger_root]
    level = WARN
    handlers = console

    [logger_ecommerce]
    level = WARN
    handlers =
    qualname = ecommerce

    [handler_console]
    class = StreamHandler
    args = (sys.stderr,)
    level = NOTSET
    formatter = generic

    [formatter_generic]
    format = %(asctime)s %(levelname)-5.5s [%(name)s][%(threadName)s] %(message)s

    # End logging configuration

我已经设法在生产网站上推出，但是，现在，它显示了500个内部服务器错误......

在apache error_log中，它显示：

    [Sun Apr 07 23:17:47 2013] [alert] [client <ip_address>] 
        /home/vretnet9/public_html/.htaccess: WSGIScriptAlias not allowed here

所以我继续看看.htaccess

的.htaccess

    Options +ExecCGI
    AddHandler cgi-script .cgi
    AddHandler wsgi-script .wsgi

    WSGIScriptAlias ECommerce /home/vretnet9/modwsgi/env/pyramid.wsgi
    WSGIDaemonProcess root processes=5 threads=1 display-name=%{GROUP}
    WSGIProcessGroup root
    WSGIApplicationGroup %{GLOBAL}

我不知道它是否应该实际调用.htaccess或者脚本应该与我的.conf中的脚本相同，而该脚本位于

    /usr/local/apache/conf/userdata/std/1/$user/$domain/modwsgi.conf

modwsgi.conf的内容如下：

    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    WSGIDaemonProcess pyramid user=vretnet9 group=vretnet9 threads=4 \
    python-path=/home/vretnet9/modwsgi/env/lib/python3.3/site-packages
    WSGIScriptAlias /ECommerce /home/vretnet9/modwsgi/env/pyramid.wsgi

    <Directory /home/vretnet9/modwsgi/env>
         WSGIProcessGroup pyramid
         Order allow,deny
         Allow from all
    </Directory>

修改在apache error_log中，正在记录以下内容：

    [Mon Apr 08 02:17:22 2013] [error] Traceback (most recent call last):
    [Mon Apr 08 02:17:22 2013] [error] File 
          "/home/vretnet9/modwsgi/env/pyramid.wsgi", line 5, in <module>
    [Mon Apr 08 02:17:22 2013] [error] from pyramid.paster import get_app, 
          setup_logging
    [Mon Apr 08 02:17:22 2013] [error] File "/home/vretnet9/modwsgi/env/
          lib/python3.3/site-packages/pyramid/paster.py", line 1, in <module>
    [Mon Apr 08 02:17:22 2013] [error]     import os
    [Mon Apr 08 02:17:22 2013] [error] ImportError: No module named os

编辑＃2

这是我在shell中运行时的结果：

    [~/modwsgi/env]# python
    Python 3.3.0 (default, Mar 27 2013, 09:31:49) 
    [GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import os
    >>> print (os.getcwd())
    /home/vretnet9/modwsgi/env

这不是你如何使用mod_wsgi + Apache将金字塔项目投入生产。我建议阅读The official documentation

运行../bin/pserve production.ini时，它会在端口8080（在production.ini中定义）启动粘贴HTTP服务器

理想情况下，您需要在新的虚拟环境中安装金字塔，然后配置mod_wsgi以使用 python实例。您必须在项目中添加.wsgi脚本并配置mod_wsgi以在Apache启动时运行该脚本。

修改

ScriptAlias（以及所有相关部分）应该在你的modwsgi.conf中（确保你在实际的apache conf中导入modwsgi.conf）。

在该文件中，你应该定义你的PYTHONPATH和PYTHONHOME（特别是如果你有一个virtualenv）和你已经定义的其他东西（WSGIApplicationGroup，WSGIScriptAlias等）

重要 - 确保您的apache用户（apache）对.wsgi脚本具有读取执行权限。这意味着即使您的/ home目录也应该可以被apache访问。

我建议creatijg一个seaparate目录（比如/ opt / proj）来托管应用程序和另一个（比如环境的/ opt / env）。

这是我的pyramid.conf的样子。我有 Python 2.6 并在/ opt / save_project中保留我的项目（只有静态内容，如css，images，js和.wsgi脚本）。我的virtualenv是/ opt / pyra

WSGIPythonHome /opt/pyra WSGIPythonPath /opt/pyra/lib/python2.6 <VirtualHost 31.1.1.22:8005> DocumentRoot /opt/save_project WSGIApplicationGroup %{GLOBAL} WSGIPassAuthorization On WSGIProcessGroup %{GLOBAL} WSGIDaemonProcess pyramid user=apache group=apache \ python-path=/opt/pyra/lib/python2.6 WSGIScriptAlias / /opt/save_project/pyramid.wsgi # Get the static and favicon.ico pages working by properly aliasing them Alias /favicon.ico /opt/save_project/static/images/favicon.ico Alias /static /opt/save_project/static <Directory /opt/save_project> AllowOverride all Options -MultiViews </Directory> </VirtualHost>
