tornado+WSGI+Apache
1、原理2、安装mod_wsgi
http://pan.baidu.com/s/1sjsccWH
configure的时候会找对应的python脚本，默认是/usr/bin/python
生成mod_wsgi.so,拷贝到apache的modules下面
3、apache的配置：
LoadModule wsgi_module modules/mod_wsgi.so
WSGIScriptAlias /myapp /usr/local/sinasrv2/var/www/wsgi-scripts/myapp.wsgi
AllowOverride all
Options Indexes FollowSymLinksExecCGI
Order allow,deny
SetHandler wsgi-script
Allow from all
4、wsgi的脚本：
#!/usr/bin/env python26
import tornado.web
import tornado.wsgi
import wsgiref.simple_server
import wsgiref.handlers
class MainHandler(tornado.web.RequestHandler):
def get(self):
self.write("Hello, world,AAAA,WSGI")
def application(environ, start_response):
if 'SCRIPT_NAME' in environ:
tornado_app = tornado.wsgi.WSGIApplication([
(r"/myapp", MainHandler),
])
return tornado_app(environ,start_response)
if __name__ == "__main__":
tornado_app = tornado.wsgi.WSGIApplication([
(r"/myapp", MainHandler),
])
server = wsgiref.simple_server.make_server('',6188, application)
server.serve_forever()
必须设置application函数，否则会出现下面的错误信息：
mod_wsgi (pid=3309): Exception occurred processing WSGI script '/us
r/local/sinasrv2/var/www/wsgi-scripts/myapp.wsgi'
5、测试
6、遇到的问题
Traceback (most recent call last):
File "/usr/local/sinasrv2/var/www/wsgi-scripts/myapp.wsgi", line 11, in
os.chdir(sys.path)
OSError: Not a directory: '/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg'
原因在于调用的时候使用如下代码：
os.chdir(sys.path)
sys.path.append("./lib")
apache调用的时候path为
usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg
路径引用的时候使用：
sys.path.append(os.path.dirname(__file__) + os.sep + 'lib')
