由于.sqlite文件操作的诸多不便，决定常识用MySQL代替书上的SQLite作为数据库。
1.在虚拟环境中安装mysql-Python具体步骤为：
<1> 安装python-dev
sudo apt-get install python-dev
<2>安装 libmysqlclient-dev
sudo apt-get install libmysqlclient-dev
<3>安装mysql-python
pip install mysql-python
2.安装完成后发现MySQLdb模块在虚拟环境中可成功导入，则说明安装成功，下面是使用mysql代替sqlite的方法：
<1>更改SQLALCHEMY_DATABASE_URI变量为：'mysql://root:thinkive@127.0.0.1:3306/BlogTest'
<2>在mysql中创建名为BlogTest的库
create database BlogTest default character set utf8 collate utf8_general_ci;
此时，数据库表里是空的没有任何数据
<3>创建数据库表和字段
