没有数据库支持的程序都是耍流氓

安装mysql驱动

在下面的网址下载mysqldb模块：
http://sourceforge.net/projects/mysql-python/
不用怀疑，2010年的版本；
在mac os x直接双击解压,命令行进入解压后的目录， 执行python setup.py build

python setup.py install

运行后发现没有安装mysql，这个时候编译python-mysql可能无法通过，抓紧下载mysql for mac
www.baidu.com上搜索mysql for mac，下载安装

安装方法，请参考
https://dev.mysql.com/downloads/mysql/
下载dmg版本，300M+

编译python setup.py build报错

这里需要修改python-mysql中的site.cfg中的关于mysql_config的配置，打开site.cfg.找到mysql_config，去掉注释，修改到/usr/local/mysql/bin（默认安装后的mysql，会在此目录下生成mysql_config文件）

修改后，编译通过，很快。

安装mysql-python完成，修改环境变量

打开终端，在终端中使用vim打开“~/.bash_profile”，如果没有安装vim，那就显示隐藏文件用文本编辑器打开，具体操作这里就不复述了。在.bash_profile中添加以下内容：
PATH="/usr/local/mysql/bin:${PATH}" export PATH export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/ export VERSIONER_PYTHON_PREFER_64_BIT=no export VERSIONER_PYTHON_PREFER_32_BIT=yes

启动mysql

打开控制面板，找到mysql控制台，启动mysql

找到python操作mysql的样例，修改mysql的配置文件

下载mysql for mac的客户端

https://dev.mysql.com/downloads/workbench/

很郁闷，下载后登录不了，修改root密码
mac上安装mysql路径： /usr/local/mysql/

修改root密码

cd ／usr/local/mysql/bin sudo su ./mysqld_safe --skip-grant-tables

重新打开一个终端
cd /usr/local/mysql/bin mysql flush privileges; set password for 'root'@'localhost'=password('fith2017');

退出后，kill掉进程
kill -9 mysqld_safe

添加mysql环境

打开一个终端
命令：vim ~/.bash_profile
最后一行添加 PATH=$PATH:/usr/local/mysql/bin，保存退出
命令source ~/.bash_profile

这里编译还有可能出现异常

_mysql.c:44:10: fatal error: 'my_config.h' file not found

这是因为XAMPP等，如果是IDE安装的话，没有编译环境，所以需要单独安装mysql-connector-c或者重新安装mysql

brew install mysql-connector-c
