python之apache2、mod_wsgi、python 网络应用程序(bottle 框架)

注意:我想瓶子框架在这里不相关。 Wsgi 是。

我已经设法配置我的 apache 以使用 wsgi 和基于 python bottle 框架的单文件 web 应用程序。下面的文件是我现在得到的——apache 使用 virtualenv 并运行一个包含所有内容的 wsgi/py 文件。

虚拟主机:

<VirtualHost *:80> 
    ServerName bottle-test 
 
    WSGIDaemonProcess bottle-test user=www-data group=www-data processes=1 threads=5 
    WSGIScriptAlias / /home/tducin/Development/Python/bottle-test/src/app.wsgi 
 
    <Directory /home/tducin/Development/Python/bottle-test/src> 
        WSGIProcessGroup bottle-test 
        WSGIApplicationGroup %{GLOBAL} 
        Order deny,allow 
        Allow from all 
    </Directory> 
    ErrorLog /var/log/apache2/wsgi/error-bottle.log 
    CustomLog /var/log/apache2/wsgi/access-bottle.log combined 
</VirtualHost> 

httpd.conf(这是我的 virtualenv 所在的位置):

WSGIPythonHome /home/tducin/Development/Python/bottle-test 

最后，这是 app.wsgi:

import os 
 
# Change working directory so relative paths (and template lookup) work again 
os.chdir(os.path.dirname(__file__)) 
 
import bottle 
 
app = bottle.Bottle() 
 
@app.route('/') 
def siema(): 
    return bottle.template('<h1>SIEMA {{arg}}!</h1>', arg='Janie') 
 
@app.route('/hello/<name>') 
def hello(name): 
    return bottle.template('<b>Hello {{name}}</b>!', name=name) 
 
application = app 

我想做的是将 wsgi 层与应用程序的其余部分分开。我试过几次从另一个文件导入应用程序，但每次都出现 Failed to import module 错误。有谁知道如何将 wsgi 与应用程序分开？

---

编辑:我将 httpd.conf 移动到 wsgi.conf(它已加载)，现在我有以下内容:

WSGIPythonHome /home/tducin/Development/Python/bottle-test 
WSGIPythonPath /home/tducin/Development/Python/bottle-test/src 

问题是现在我得到错误 500，apache 错误日志是:

[Wed Feb 05 09:24:32 2014] [error] [client 127.0.0.1] mod_wsgi (pid=4260): Target WSGI script '/home/tducin/Development/Python/bottle-test/src/app.wsgi' cannot be loaded as Python module. 
[Wed Feb 05 09:24:32 2014] [error] [client 127.0.0.1] mod_wsgi (pid=4260): Exception occurred processing WSGI script '/home/tducin/Development/Python/bottle-test/src/app.wsgi'.

[Wed Feb 05 09:24:32 2014] [error] [client 127.0.0.1]     import server 
[Wed Feb 05 09:24:32 2014] [error] [client 127.0.0.1] ImportError: No module named server 

src/server.py 包含 bottle 应用程序的东西。 app.wsgi 文件获得了完整的可执行权限:

-rwxrwxr-x 1 tducin tducin  377 Feb  5 09:22 app.wsgi 

请您参考如下方法:

以下方法对我有用。
第 1 步:配置虚拟主机:
Linux 路径:/etc/apache2/sites-available/default

<VirtualHost *:80> 
    ServerAdmin webmaster@localhost 
 
    WSGIDaemonProcess my_working_dir user=www-data group=www-data 
    WSGIScriptAlias /my_working_dir /var/www/my_working_dir/app.wsgi 
 
    <Directory /var/www/my_working_dir> 
               WSGIProcessGroup my_working_dir 
               WSGIApplicationGroup %{GLOBAL} 
               Order deny,allow 
               Allow from all 
    </Directory> 
    ErrorLog ${APACHE_LOG_DIR}/error.log 
    CustomLog ${APACHE_LOG_DIR}/access.log combined 
</VirtualHost> 

第二步:配置app.wsgi文件。
路径:/var/www/my_working_dir/app.wsgi

import sys, os 
 
# Change working directory so relative paths (and template lookup) work again 
os.chdir(os.path.dirname(__file__)) 
sys.path.append(os.path.dirname(__file__)) 
 
# ... build or import your bottle application here ... 
# Do NOT use bottle.run() with mod_wsgi 
 
import bottle 
from rs import app as application 
from bottle import route 
import hello_world 
application=bottle.default_app() 

注意:导入文件时不使用 .py 扩展名。 (导入 Hello World )

第 3 步:创建 hello_world.py
路径:/var/www/my_working_dir/hello_world.py

from bottle import route, run 
 
@route('/hello') 
def hello(): 
    return "Hello World!" 
 
#Comment out the localhost part, to test Apache configuration.  
#run(host='localhost', port=8080, debug=True) 

第 4 步:重启您的 Apache 服务器并使用 Curl 测试您的 API:
$ curl -i GET "http://[主机名]/hello"

输出:

HTTP/1.1 200 OK 
Date: Thu, 06 Aug 2015 21:51:54 GMT 
Server: Apache/2.2.22 (Ubuntu)
