一个人如何部署OS X Server上的Django应用程序？

问题描述

如何将一个没有使用自制的或不同的风味蟒一个比随OS X 10.8.1部署OS X服务器2.0 Django应用程序？我使用可可绑定在一个Django应用程序，并有麻烦它与我的自制软件的台式机上运行（运行OS X 10.8.1）;因此，要求对部署的Python安装系统版本的应用程序。

How would one deploy a Django application on OS X Server 2.0 without using homebrew or a different flavor of python than the one shipped with OS X 10.8.1? I'm using the cocoa bindings in a Django application and had trouble getting it to work with homebrew on my desktop machine (running OS X 10.8.1); hence the request to deploy the application on the system installed version of Python.

我有以下的OS X Server环境中，具有以下已安装：

I have the following OS X Server environment, with the following already installed:

• OS X 10.8.1


• OS X Server 2.0的


• 的Python 2.7.2


• 的Apache 2.2.22

1.4.1的Django使用以下命令安装：

Django 1.4.1 was installed using the following command:

sudo easy_install django

我的第一次尝试是部署一个空的网站，一旦成功，部署生产中使用实际的应用程序。该项目于创建/库/服务器/网络/数据/ webapps /下的mysite / 使用下面的命令

django-admin.py startproject mysite

我使用下面的命令运行应用程序。它只是证实了该应用程序启动和运行。这是标准的成功了！页当你第一次创建一个项目。

I ran the application using the following command. It simply confirmed that the application was up and running. It is the standard "It worked!" page when you first created a project.

python manage.py runserver 8080

然后我创建了一个文件 /Library/Server/Web/Config/apache2/httpd_mysite.conf 包含以下内容：

WSGIScriptAlias /mysite /Library/Server/Web/Data/WebApps/mysite/mysite/wsgi.py

我还创建了一个文件 /Library/Server/Web/Config/apache2/webapps/com.example.mysite.wsgi.plist 包含以下内容：

<?xml version="1.0" encoding="UTF-7"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>name</key>
        <string>com.example.mysite.wsgi</string>
        <key>displayName</key>
        <string>Python "My Site" app</string>
        <key>launchKeys</key>
        <array/>
        <key>proxies</key>
        <dict/>
        <key>installationIndicatorFilePath</key>
        <string>/Library/Server/Web/Data/WebApps/mysite/mysite/wsgi.py</string>
        <key>includeFiles</key>
        <array>
                <string>/Library/Server/Web/Config/apache2/httpd_mysite.conf</string>
        </array>
        <key>requiredModuleNames</key>
        <array>
                <string>wsgi_module</string>
        </array>
</dict>
</plist>

文件 com.example.mysite.wsgi.plist 从 com.apple.webapp.wsgi.plist 和 httpd_mysite.conf 改编自 httpd_wsgi.conf 。这两个文件被用来成功运行独立Python应用程序通过服务器管理器配置为当。

The file com.example.mysite.wsgi.plist was adapted from com.apple.webapp.wsgi.plist and httpd_mysite.conf adapted from httpd_wsgi.conf. Both these files are used to run the "standalone" python application successfully when configured through the server manager.

然后我创建了服务器管理网站，证实了我的应用程序是在Web应用程序列表。然而，当我访问我得到一个500错误。日志具有以下条目（IP地址改为1.2.3.4对于隐私的原因）：

I then created a site with the server manager, confirmed my application was in the list of web applications. However, when I visit http://example.com/mysite I get a 500 error. The logs has the following entries (IP addresses changed to 1.2.3.4 for privacy reasons):

[Sat Sep 01 21:49:17 2012] [warn] Init: Name-based SSL virtual hosts only work for clients with TLS server name indication support (RFC 4366)
[Sat Sep 01 21:49:17 2012] [notice] Apache/2.2.22 (Unix) PHP/5.3.13 with Suhosin-Patch mod_wsgi/3.3 Python/2.7.2 mod_fastcgi/2.4.6 mod_ssl/2.2.22 OpenSSL/0.9.8r DAV/2 configured -- resuming normal operations

[Sat Sep 01 21:50:13 2012] [error] [client 1.2.3.4] Premature end of script headers: wsgi.py

这似乎并不认为WSGI模块处理请求，而是，请求可以使用FCGI进行处理。然而，该日志表明的mod_wsgi / 3.3 加载。

当我创建了一个标准的Python应用程序，如下所示：

When I created a standard Python application that looks as follows:

def application(environ, start_response):
    status = '200 OK'
    output = 'Hello World!'

    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]
    start_response(status, response_headers)

    return [output]

和更新文件，以指向 /Library/Server/Web/Data/WebApps/helloworld.wsgi ，而不是 /库/服务器/网络/数据/ webapps /下的mysite / mysite的/ wsgi.py 然后Hello World的显示。因此，我认为WSGI正确配置，并能够执行应用程序和其他东西是错的我的设置。

And update the files to point to /Library/Server/Web/Data/WebApps/helloworld.wsgi rather than /Library/Server/Web/Data/WebApps/mysite/mysite/wsgi.py then "Hello World" is displayed. I therefore assume that wsgi is correctly configured and able to execute applications and that something else is wrong with my setup.

推荐答案

有些Apache的配置与发行版地图的.py要么CGI或FASTCGI，这将与mod_wsgi的冲突。这就是为什么mod_wsgi的建议使用.wsgi扩展。所以，重命名wsgi.py'到'site.wsgi'，然后在WSGIScriptAlias​​使用'site.wsgi'

Some Apache configurations with distros map .py to either CGI or FASTCGI and this will conflict with mod_wsgi. This is why mod_wsgi recommends using a .wsgi extension. So, rename 'wsgi.py' to 'site.wsgi' and then use 'site.wsgi' in the WSGIScriptAlias.

顺便说一句，你可以确认有一个precompiled mod_wsgi.so随山狮服务器。

BTW, can you confirm that there is a precompiled mod_wsgi.so shipped with Mountain Lion server.
