Mac OS X10.9.3安装mysq

   因为最近换了工作的原因，没有机会接触云计算，加上其他一些非技术原因，不方便在博客上面记录关键的东西，最近写得东西基本都是自己学习的积累，高手直接飘过即可。

   最近在学习python的Django架构，学到数据库连接这部分，需要import Mysqldb这个模块，系统自带没有安装，于是乎用最简单的方法安装

sudo easy_install mysql_Python

顺利安装成功后，执行如下命令导入模块测试，发现仍旧报错

>>> import Mysqldb

Traceback (most recent call last):

ImportError: dlopen(/Users/bruce/.python-eggs/MySQL_python-1.2.5-py2.7-macosx-10.9-intel.egg-tmp/_mysql.so, 2): Library not loaded: libmysqlclient.18.dylib

  Referenced from: /Users/bruce/.python-eggs/MySQL_python-1.2.5-py2.7-macosx-10.9-intel.egg-tmp/_mysql.so

  Reason: p_w_picpath not found

解决方法：创建软连接或者修改环境变量

ClovemFongdeMacBook-Pro:~ bruce$ sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

然后就OK了
