MySQLdb安装指南

默认情况下,MySQLdb包是没有安装的,不信? 看到类似下面的代码你就信了。
-bash-3.2# /usr/local/python2.7.3/bin/python get_cnblogs_news.py
Traceback (most recent call last):
  File "get_cnblogs_news.py", line 9, in <module>
    import MySQLdb
ImportError: No module named MySQLdb

这时我们就不得不安装MySQLdb包了。安装其实也挺简单,具体步骤如下:
 1、下载 MySQL for Python
地址:http://sourceforge.net/projects/mysql-python/files/mysql-python/
我这里安装的是1.2.3版本
wget http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz

2、解压
tar zxvf MySQL-python-1.2.3.tar.gz

3、安装
$ cd MySQL-python-1.2.3
$ python setup.py build

不过在python setup.py build时报错:

ImportError: No module named setuptools

ubuntu下安装:

sudo apt-get install python-setuptools

python-setuptools : Python Distutils Enhancements (setuptools compatibility)

 

然后再次python setup.py build,又报错:

EnvironmentError: mysql_config not found

因为mysql_config是属于MySQL开发用的文件,而使用apt-get安装的MySQL是没有这个文件的,于是在包安装器里面寻找

sudo apt-get install  libmysqld-dev

libmysqld-dev : MySQL embedded database development files

再次运行python setup.py build,报错:

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/usr/include/mysql -I/usr/include/python2.7 -c _mysql.c -o build/temp.linux-i686-2.7/_mysql.o -DBIG_JOINS=1 -fno-strict-aliasing -DUNIV_LINUX -DUNIV_LINUX
In file included from _mysql.c:29:0:
pymemcompat.h:10:20: fatal error: Python.h: No such file or directory

解决方案,

sudo apt-get install python-dev

python-dev : header files and a static library for Python (default)

 

然后就按照README里的:

  pythonsetup.pybuild
sudo python setup.py install

测试:

>>>import MySQLdb

没有报错即可。
