cygwin安装python-mysql

1 安装 mysql-5.0.56.tar.gz

下载地址  http://down.51cto.com/data/320800

    $ tar -zxvf mysql-5.0.56.tar.gz 

    $ cd mysql-5.0.56

    $ ./configure --without-server
    $ ./make

一堆异常，和readline有关

mysql.cc:315: error: redefinition of ‘struct _hist_entry’
../include/readline/readline.h:53: error: previous definition of ‘struct _hist_entry’
mysql.cc:318: error: invalid type in declaration before ‘;’ token
mysql.cc:318: error: conflicting declaration ‘typedef int HIST_ENTRY’
../include/readline/readline.h:56: error: ‘HIST_ENTRY’ has a previous declaration as ‘typedef struct _hist_entry HIST_ENTRY’
mysql.cc: In function ‘void initialize_readline(char*)’:
mysql.cc:1622: error: ‘rl_completion_func_t’ was not declared in this scope
mysql.cc:1622: error: expected primary-expression before ‘)’ token
mysql.cc:1623: error: ‘rl_compentry_func_t’ was not declared in this scope
mysql.cc:1623: error: expected primary-expression before ‘)’ token
mysql.cc: In function ‘char** new_mysql_completion(const char*, int, int)’:
mysql.cc:1649: error: ‘rl_completion_matches’ was not declared in this scope

$ make clean   #重要，鼓捣了好几次，运行clean后才成功
$ ./configure --without-server --without-readline
$ make

再没见到error字样，输入

$ mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

没提示找不到mysql，应该是安装成功了

2 安装mysql-python setuptools

 wget http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz/download

$ tar -zxvf MySQL-python-1.2.3.tar.gz

$ cd MySQL-python-1.2.3

$ python setup.py build
Traceback (most recent call last):
  File "setup.py", line 5, in
    from setuptools import setup, Extension
ImportError: No module named setuptools

提示没有setuptools，“setuptools是 Python Enterprise Application Kit（PEAK）的一个副项目，它 是一组Python的 distutilsde工具的增强工具(适用于 Python 2.3.5 以上的版本，64 位平台则适用于 Python 2.4 以上的版本)，可以让程序员更方便的创建和发布 Python 包，特别是那些对其它包具有依赖性的状况。”--百度百科

安装setuptools，很顺利。参考baidu的一个帖子~

$ wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz
$ tar zxvf setuptools-0.6c11.tar.gz
$ cd setuptools-0.6c11
$ python setup.py build
$ python setup.py install

接着安装python-mysql，修改site.cfg文件

$ cd MySQL-python-1.2.3

 $ whereis mysql

mysql: /usr/local/bin/mysql.exe /usr/local/lib/mysql

 $ whereis mysql_config
mysql_config: /usr/local/bin/mysql_config /opt/mysql/bin/mysql_config

修改后的文件

[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 = False
static = True

# 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

# The Windows registry key for MySQL.
# This has to be set for Windows builds to work.
# Only change this if you have a different version.
# registry_key = SOFTWARE\MySQL AB\MySQL Server 5.0

（a）放开mysql_config项，内容是whereis mysql_config检索结果，后面的/opt/mysql/bin/mysql_config没有测试过，估计也好使~

（b）关闭registry_key注册表项

（c）最上面的3个True，False选项参考其他帖子的。

$ python setup.py build
$ python setup.py install

没见着安装成功的提示信息，不过没显示error，：） 测试下

$ python
Python 2.6.5 (r265:79063, Jun 12 2010, 17:07:01)

>>> import MySQLdb
/usr/lib/python2.6/site-packages/MySQL_python-1.2.3-py2.6-cygwin-1.7.9-i686.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /usr
/lib/python2.6/site-packages/MySQL_python-1.2.3-py2.6-cygwin-1.7.9-i686.egg/_mysql.pyc, but /cygdrive/d/MySQL-python-1.2.3 is being added to sys.path

好像是有冲突了，ls一把，还是看不明白

/cygdrive/d/MySQL-python-1.2.3
$ ls

百度下， install后MySQLdb模块已经被放到python的site-packages目录中；但在当前目录也存在相同的模块，所以可能会重复导入。换个目录再试试

$ python
Python 2.6.5 (r265:79063, Jun 12 2010, 17:07:01)

>>> import MySQLdb
>>>

大功告成，不再提示错误信息了。

3 连下mysql - server瞅瞅，mysql_test.py

import MySQLdb

try:
	connection = MySQLdb.connect(user="***",passwd="***",host="*.*.*.*",db="test")
except:
	print "Could not connect to MySQL server."
	exit( 0 )

cursor = connection.cursor()
cursor.execute("SELECT parent_id,sku_id FROM datong where sku_id = 0")
print "Rows selected:", cursor.rowcount
					      
for row in cursor.fetchall():
    print "sku : ", row[0], row[1]
cursor.close()

sku :  2147483647 0
sku :  2147483647 0
sku :  2147483647 0
sku :  2147483647 0
sku :  2147483647 0
