The last stable release is available on PyPI and can be installed with pip:
$ pip install Tornado-MySQLIf you would like to run the test suite, first copy the file .travis.databases.json to tornado_mysql/tests/databases.json and edit the new file to match your MySQL configuration:
$ cp .travis.databases.json tornado_mysql/tests/databases.json
$ $EDITOR tornado_mysql/tests/databases.jsonTo run all the tests, execute the script runtests.py:
$ python runtests.pyA tox.ini file is also provided for conveniently running tests on multiple Python versions:
$ toxDB-API 2.0: http://www.python.org/dev/peps/pep-0249
