背景

折腾:

【记录】使用Python操作MySQL数据库

的过程中,需要去安装MySQLdb。

下载MySQLdb

去官网:

http://pypi.python.org/pypi/MySQL-python/

看到有1.2.4和1.2.3

所以去最新的1.2.4:

http://pypi.python.org/pypi/MySQL-python/1.2.4

下载对应的编译好的版本:

MySQL-python-1.2.4.win32-py2.7.exe

得到1MB的

MySQL-python-1.2.4.win32-py2.7.exe

安装MySQLdb

双击安装:

mysql python install main ui

结果出错:

not found in the reg for python 2.7

看来此x86的exe,是不支持我的win7 x64。

所以只能去下载源码再去安装了。

下载源码:

MySQL-python-1.2.4.zip

然后再去解压和安装,结果果然出现

error: Unable to find vcvarsall.bat

的错误:

然后参考之前的办法,结果还是出错:

D:\tmp\dev_tools\python\mysql\MySQL-python-1.2.4\MySQL-python-1.2.4>         

然后再参考:

Windows下安装MySQLdb遇到的问题及解决方法

所说的:

1)问题 : _mysql.c(34) : fatal error C1083: Cannot open include file: ‘config-win.h’: No such file or directory      
error: command ‘”C:/Program Files/Microsoft Visual Studio 9.0/VC/BIN/cl.exe”‘ failed with exit status 2

原因 :原因是安装MySQL的时候没有安装C语言库。

解决 :重新运行MySQL的安装程序,选择Modify,把“C Include Files / Lib Files”勾选上,并安装。

去重新安装mysql。

 

 

继续:

【记录】为Python安装MySQL数据库模块:MySQLdb

的折腾:

1.参考:

MySQL-python 1.2.3 for Windows and Python 2.7, 32bit and 64bit versions

得知:

python的

此处的要安装x64还是x86,是取决于你所安装的Python的版本,而不是OS的版本。

所以此处去x64 win7中的cmd中确认一下python的版本:

C:\Users\CLi>python
Python 2.7.3 (default, Apr 10 2012, 23:24:47) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

的确是x64的,所以的确要安装的是x64。

2.下载对应的:

MySQL-python-1.2.3.win-amd64-py2.7.exe (1.0 MiB)

结果链接失效:“File does not exist.”

3.从:

http://www.codegood.com/downloads

找到一堆的下载,但是结果都失效了。

4.参考:

Python: How to install mysqldb on windows 7 x64?

结果最后找到的下载地址也是上面的那个失效的地址。

5.还是参考:

Install MySQLdb for Python 2.6 in Windows 7 64-bit

python MySQLdb在windows环境下的快速安装、问题解决方式

去自己编译吧。

6.然后还是同样错误:

然后参考:

Install Python-MySql on Windows 7 64-bit

看到了site.cfg内容是:

[options]
# embedded: link against the embedded server library
# threadsafe: use the threadsafe client
# static: link against a static library (probably required for embedded)

embedded = False
threadsafe = True
static = False

# The path to mysql_config.
# Only use this if mysql_config is not on your PATH, or you have some weird
# setup that requires it.
#mysql_config = /usr/local/bin/mysql_config

# http://stackoverflow.com/questions/1972259/mysql-python-install-problem-using-virtualenv-windows-pip
# Windows connector libs for MySQL. You need a 32-bit connector for your 32-bit Python build.
connector = C:\Program Files (x86)\MySQL\MySQL Connector C 6.0.2

然后注意到了,上面的编译过程中的include的路径,就是此处的connector的值。

7.又在这里:

Unofficial Windows Binaries for Python Extension Packages

找到了一个已编译的版本的下载地址:

MySQL-python-1.2.3.win-amd64-py2.7.exe [1.1 Mb] [Python 2.7] [64 bit] [JUN 08, 2011]

然后去安装:

mysql python 1.2.3 x64 main ui_thumb

found python 2.7 install path_thumb

next to install python 2.7 mysql_thumb

done to finish install mysql for python 2.7 version_thumb

然后就可以写代码去测试是否工作了。

在Python中使用MySQLdb操作MySQL数据库

参考:

python操作MySQL数据库

然后用:

#!/usr/bin/python
# -*- coding: utf-8 -*-

可以显示连接成功了:

D:\tmp\tmp_dev_root\python\tutorial_summary\python_mysql_test>python_mysql_test.py

conn= <_mysql.connection open to ‘localhost’ at 2a46ad8>

cur= <MySQLdb.cursors.Cursor object at 0x0000000002A54C50>

对应的wordpress的数据库是:

has exist wp_users in wordpress db_thumb

9.再去折腾新建数据项试试:

createdDb= 1

selectedDb= None

createdTable= 0

insertedValue= 1

insertedValues= 20

updatedInfo= 1

committed= None

closedCur= None

closedConn= None

数据库中去看看结果:

newly created pythonmysql db_thumb

can show all db test data include updated one_thumb

都是可以正常工作的。

至此,简单的操作,到此结束。

以后就是针对要操作的数据,如何导入数据库,如何操作数据库了。

 

【总结】

安装好PythonMQL后,参考了别人的示例代码,

剩下的,就是以后遇到要保存的数据,去保存操作数据库的事情了。

需要后续好好学习mysql如何操作的。
