mod_wsgi 中的 Hello World [英] Hello World in mod_wsgi
问题描述
在使用 mod_wsgi
使我的 Flask 应用程序在 Apache 上运行的过程中反复失败后,我决定尝试运行 hello world 示例.这是我所拥有的 -
After failing repeatedly in my quest to get my flask application to run on Apache using mod_wsgi
I decided to try running the hello world example. Here is what I have -
目录结构(我把apache默认的/var/www
改成了~/public_html
)
Directory Structure (I changed the apache default /var/www
to ~/public_html
)
- public_html
- wsgi-scripts
- test_wsgi.wsgi
- test_wsgi
- test_wsgi.wsgi
test_wsgi.wsgi 文件
test_wsgi.wsgi file
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]
VirtualHost 配置文件(称为 testwsgi)-位于 /etc/apache2/sites-enabled/
VirtualHost Configuration file (called testwsgi) - This resides in /etc/apache2/sites-enabled/
<VirtualHost *:80>
DocumentRoot ~/public_html/test_wsgi
<Directory ~/public_html/test_wsgi>
Order allow,deny
Allow from all
</Directory>
WSGIScriptAlias /wsgi ~/public_html/wsgi-scripts/test_wsgi.wsgi
<Directory ~/public_html/wsgi-scripts>
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
当我尝试在浏览器上访问 localhost/wsgi
时,我收到 404 Not Found 错误.我究竟做错了什么?这是我第一次尝试在生产服务器上部署应用程序.到目前为止,我采用了使用 Google App Engine 的简单方法.在它启动并运行之前,我无法继续部署我的烧瓶应用程序.非常感谢!
When I try going to localhost/wsgi
on the browser I get a 404 Not Found error. What am I doing wrong? This is the first time I'm trying to deploy an app on a production server. Until now I took the easy way of using Google App Engine. I cant proceed to deploy my flask app until this is up and running. Thanks a lot!
推荐答案
需要使用绝对路径,即不要使用~
.这对我来说很好用...
You need to use an absolute path, i.e. don't use ~
. This works fine for me...
[mpenning@tsunami public_html]$ sudo cat /etc/apache2/sites-available/wsgi_test
<VirtualHost *:80>
ServerName wsgihost
DocumentRoot /home/mpenning/public_html
WSGIScriptAlias / /home/mpenning/public_html/test.wsgi
</VirtualHost>
[mpenning@tsunami public_html]$
首先我在 /etc/hosts
中设置了一个主机名,这样我就可以确保我可以在查询中多路复用主机名...
First I set up a hostname in /etc/hosts
, so I could ensure that I can mux on the hostname in the query...
[mpenning@tsunami public_html]$ grep wsgihost /etc/hosts
127.0.1.1 tsunami.foo.net tsunami wsgihost
[mpenning@tsunami public_html]$
重启 apache,并发出 wget...
Restart apache, and issue a wget...
[mpenning@tsunami public_html]$ wget http://wsgihost/
--2012-08-29 05:50:26-- http://wsgihost/
Resolving wsgihost... 127.0.1.1
