安装python MySQLdb 模块 出错及解决办法

昨天在安装python的 MySQLdb模块时遇到几个问题，写出来和大家分享下。

1.下载MySQLdb模块
wget
解压：tar -zxvf MySQL-python-1.2.3c1.tar.gz
安装：python setup.py install

出错（1）：ImportError: No module named setuptools
错误原因：没有安装setuptools
解决办法： 到这里下载   
                    wget -q   
                    python ez_setup.py

出错（2）：pymemcompat.h:10:20: error: Python.h: No such file or directory
出错原因：没有安装python-devel
解决办法：yum install python-devel


现在运行python setup.py install 就ok了

可以试试运行python
python
>>>import MySQLdb(一定要注意大小写)
/usr/lib64/python2.4/site-packages/MySQL_python-1.2.3c1-py2.4-linux-x86_64.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /usr/lib64/python2.4/site-packages/MySQL_python-1.2.3c1-py2.4-linux-x86_64.egg/_mysql.pyc, but /home/younema/MySQL-python-1.2.3c1 is being added to sys.path
>>> 

出错原因：以为安装目录里存在sys.path
解决办法：退出当前安装目录，再运行python解释器，import MySQLdb  就ok了
