准备用Python写点脚本练练手，于是在Ubuntu上安装Python的MySQLdb，本以为很简单的事，没想到还碰到几个小波折，因此记录一下以备忘。

首先需要安装Python-dev，否则后面编译MySQLdb的时候会报错，找不到头文件：

building '_mysql' extension

gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC

-Dversion_info=(1,2,3,'final',0) -D__version__=1.2.3

-I/u01/mysql/include/mysql -I/usr/include/python2.6 -c _mysql.c

-o build/temp.linux-i686-2.6/_mysql.o -DUNIV_LINUX

In file included from _mysql.c:29:

pymemcompat.h:10: fatal error: Python.h: 没有那个文件或目录

compilation terminated.

error: command 'gcc' failed with exit status 1

sudo apt-get install python-dev

其次需要先安装setuptools，否则MySQLdb无法编译

ImportError: No module named setuptools

setuptools从http://pypi.python.org/pypi/setuptools下载

python setup.py build

sudo python setup.py install

从http://sourceforge.net/projects/mysql-python下载MySQLdb

修改site.cfg将mysql_config指向正确的位置

python setup.py build

sudo python setup.py install

最后还需要安装libmysqlclient-dev，否则import模块的时候会出错

ImportError: libmysqlclient_r.so.16: cannot open shared object file:

No such file or directory

sudo apt-get install libmysqlclient-dev

装完以后，来个hello world式的简单查询

#!/usr/bin/env python

import MySQLdb

db=MySQLdb.connect(host="host_name",db="mysql",user="ningoo",passwd="password")

c=db.cursor()

n=c.execute("select user,host from user")

for row in c.fetchall():

for col in row:

print col

想在服务器上需要运行MYSQLDB，sudo apt-get install python-mysqldb提示安装成功，可是import MySQLdb 提示找不到此模块

sudo apt-get source python-mysqldb，想编译一下，总也不成功，总报错，估计是库不全,

sudo apt-get install python-all-dev

sudo apt-get install libmysqlclient15-dev

sudo apt-get install zlib1g-dev

再重新编译 ，OK，记录在此，以免下次有经验。
