サーバについて-構成tornadoのインストール

tornadoはpythonベースのもう一つのサーバフレームワークであり、djangoのように豊富な「ステーション構築ツール」を提供することはできませんが、epollのサポートにより、非ブロック特性が魅力的になります.以下にも簡単にインストール方法を記録します.
まずインストールtornadoをダウンロードし、実行するには次の2つのライブラリをインストールする必要があります.
1,pycurl
2, mysql-python  
 (python setup.py install)
 
tornadoはdjangoのmanageを提供していません.py,django-admin.pyなどのツールは、直接次のように符号化されます.
list_publishers.html(テンプレート)

<table>
        {% for p in publishers %}
        <tr>
        <td>Id #{{ p[0] }}</td>
        <td>Name #{{ p[1] }}</td>
        </tr>
        {% end %}
</table>

 web.py(コード)

import tornado.ioloop
import tornado.web
import tornado.database
import sqlite3

def _execute(query):
        dbPath = '/home/ciaos/django.sqlite3'
        connection = sqlite3.connect(dbPath)
        cursorobj = connection.cursor()
        try:
                cursorobj.execute(query)
                result = cursorobj.fetchall()
                connection.commit()
        except Exception:
                raise
        connection.close()
        return result

class Main(tornado.web.RequestHandler):
    def get(self):
        self.write("Main")

class ListPublishers(tornado.web.RequestHandler):
    def get(self):
        query = ''' select * from books_publisher '''
        publishers = _execute(query)
        self.render("list_publishers.html", publishers=publishers)

application = tornado.web.Application([
    (r"/", Main),
    (r"/publishers" , ListPublishers),
],debug=True)

if __name__ == "__main__":
    application.listen(8888)
    tornado.ioloop.IOLoop.instance().start()

簡単にabで性能をテストして、djangoの性能より倍高い様子です(ただし、2つのプロジェクトがデータベースを操作する方法が少し異なるため、tornadoのsqliteに対するオリジナルのサポートが見つからなかったため、説得力がありません)
