Prepare to rewrite this site with tornado, but an error occurred while discovering import tornado.database.
Copy Code code as follows:
[Root@lee ~]# python

>>> Import Tornado.web
>>> Import Tornado.database
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
Importerror:no Module named database

A lot of tutorials on the Internet is clearly written this module, how can I hint to find this module? Do I have no reason to install MYSQLDB?
Copy Code code as follows:

MYSQLDB module has been installed, it does not appear to be caused by the MySQLdb module. I tornado again, and the result is no database module.
Python module is a py file, I inverted tornado directory to see, and sure enough, did not database.py this module:

So to Tornado official website looked at the document, originally is tornado3.0 version after the abolition of the database module, but launched a similar database module torndb, I saw the source code is basically mysqldb simple package.
Download torndb,https://github.com/bdarnell/torndb

Install it, try to pour it into the torndb module.

OK, it's done.
In fact, using TORNDB and directly using the MYSQLDB module to manipulate the database is the same, look at a person's liking
