背景
折腾:
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:
结果出错:
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:
然后再去解压和安装,结果果然出现
error: Unable to find vcvarsall.bat
的错误:
D:\tmp\dev_tools\python\mysql\MySQL-python-1.2.4\MySQL-python-1.2.4>setup.py install D:\tmp\dev_tools\python\mysql\MySQL-python-1.2.4\MySQL-python-1.2.4> |
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>SET VS90COMNTOOLS=%VS100COMNTOOLS% D:\tmp\dev_tools\python\mysql\MySQL-python-1.2.4\MySQL-python-1.2.4>setup.py install D:\tmp\dev_tools\python\mysql\MySQL-python-1.2.4\MySQL-python-1.2.4> |
然后再参考:
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 |
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
和
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:
D:\tmp\dev_tools\python\mysql\MySQL-python-1.2.4\MySQL-python-1.2.4>SET VS90COMNTOOLS=%VS100COMNTOOLS% D:\tmp\dev_tools\python\mysql\MySQL-python-1.2.4\MySQL-python-1.2.4>setup.py install |
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:
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:
然后用:
#!/usr/bin/python # -*- coding: utf-8 -*- """ ------------------------------------------------------------------------------- Function: 【记录】为Python安装MySQL数据库模块:MySQLdb https://www.crifan.com/python_install_module_mysql_mysqldb/ Autor: Crifan Li Date: 2013-04-22 ------------------------------------------------------------------------------- """ #---------------------------------import--------------------------------------- import MySQLdb def python_mysql_test(): """ try to use mysql in python """ try: conn=MySQLdb.connect(host='localhost',user='root',passwd='xxx',db='wordpress',port=3306) print "conn=",conn; cur=conn.cursor() print "cur=",cur; cur.execute('select * from wp_users') cur.close() conn.close() except MySQLdb.Error,e: print "Mysql Error %d: %s" % (e.args[0], e.args[1]) ############################################################################### if __name__=="__main__": python_mysql_test();
可以显示连接成功了:
D:\tmp\tmp_dev_root\python\tutorial_summary\python_mysql_test>python_mysql_test.py cur= <MySQLdb.cursors.Cursor object at 0x0000000002A54C50> |
对应的wordpress的数据库是:
9.再去折腾新建数据项试试:
#!/usr/bin/python # -*- coding: utf-8 -*- """ ------------------------------------------------------------------------------- Function: 【记录】为Python安装MySQL数据库模块:MySQLdb https://www.crifan.com/python_install_module_mysql_mysqldb/ Autor: Crifan Li Date: 2013-04-22 ------------------------------------------------------------------------------- """ #---------------------------------import--------------------------------------- import MySQLdb def python_mysql_test(): """ try to use mysql in python """ try: conn=MySQLdb.connect(host='localhost',user='root',passwd='xxx',db='test',port=3306, charset='utf8') print "conn=",conn; cur=conn.cursor() print "cur=",cur; createdDb = cur.execute('create database if not exists pythonMysql') print "createdDb=",createdDb; selectedDb = conn.select_db('pythonMysql') print "selectedDb=",selectedDb; createdTable = cur.execute('create table test(id int,info varchar(20))') print "createdTable=",createdTable; value=[1,'hi rollen'] insertedValue = cur.execute('insert into test values(%s,%s)',value) print "insertedValue=",insertedValue; values=[] for i in range(20): values.append((i,'hi rollen'+str(i))) insertedValues = cur.executemany('insert into test values(%s,%s)',values) print "insertedValues=",insertedValues; updatedInfo = cur.execute('update test set info="I am rollen" where id=3') print "updatedInfo=",updatedInfo; committed = conn.commit() print "committed=",committed; closedCur = cur.close() print "closedCur=",closedCur; closedConn = conn.close() print "closedConn=",closedConn; except MySQLdb.Error,e: print "Mysql Error %d: %s" % (e.args[0], e.args[1]) ############################################################################### if __name__=="__main__": python_mysql_test();
结果如下:
D:\tmp\tmp_dev_root\python\tutorial_summary\python_mysql_test>python_mysql_test.py cur= <MySQLdb.cursors.Cursor object at 0x0000000002A54C50> D:\tmp\tmp_dev_root\python\tutorial_summary\python_mysql_test>python_mysql_test.py cur= <MySQLdb.cursors.Cursor object at 0x00000000028B7BE0> 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:
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。
