使用python访问mysql,需要一系列安装

linux下MySQLdb安装见 
Python MySQLdb在Linux下的快速安装
http://www.jb51.net/article/65743.htm

-------------------------------------------------------------
以下是windows环境下的:

1. 安装数据库mysql
下载地址:http://www.mysql.com/downloads/
可以顺带装个图形工具,我用的是MySQL-Front
 
2. 安装MySQLdb
 
好了,到了这一步,你有两个选择
A. 安装已编译好的版本(一分钟)
B. 从官网下,自己编译安装(介个…..半小时到半天不等,取决于你的系统环境以及RP)
 
若是系统32位的,有c++编译环境的,自认为RP不错的,可以选择自己编译安装,当然,遇到问题还是难免的,一步步搞还是能搞出来的
若是系统64位的,啥都木有的,建议下编译版本的,甭折腾
 
2.1安装已编译版本:
http://www.codegood.com/downloads
根据自己系统下载,双击安装,搞定
然后import MySQLdb,查看是否成功
 
我的,win7,64位,2.7版本

MySQL-python-1.2.3.win-amd64-py2.7.exe
 
2.2自己编译安装
话说搞现成的和自己编译差距不一一点半点的,特别是64位win7,搞死了
 
2.2.1安装setuptools

在安装MySQLdb之前必须安装setuptools,要不然会出现编译错误
http://pypi.python.org/pypi/setuptools
http://peak.telecommunity.com/dist/ez_setup.py 使用这个安装(64位系统必须用这个)
 
2.2.2安装MySQLdb

下载MySQLdb
http://sourceforge.net/projects/mysql-python/
 
解压后,cmd进入对应文件夹
如果32位系统且有gcc编译环境,直接

复制代码 代码如下:

python setup.py build

2.2.3问题汇总
A. 64位系统,无法读取注册表的问题
异常信息如下:

复制代码 代码如下:

F:\devtools\MySQL-python-1.2.3>pythonsetup.py build
Traceback (most recent call last):
 File "setup.py", line 15, in
   metadata, options = get_config()
 File "F:\devtools\MySQL-python-1.2.3\setup_windows.py", line7, in get_config
   serverKey = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, options[' registry_ke
y'] )
WindowsError: [Error 2] The system cannotfind the file specified

解决方法:
其实分析代码,发现只是寻找mysql的安装地址而已  修改setup_windows.py如下
注解两行,加入一行,为第一步mysql的安装位置
复制代码 代码如下:

   #serverKey = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE,options['registry_key'] )
   #mysql_root, dummy = _winreg.QueryValueEx(serverKey,'Location')
   mysql_root = r"F:\devtools\MySQL\MySQL Server 5.5"

B.没有gcc编译环境
复制代码 代码如下:

unable to find vcvarsall.bat

解决方法:安装编译环境(一个老外的帖子)
1)  First ofall download MinGW. Youneed g++compiler and MingW make in setup.
2)  If youinstalled MinGW for example to “C:\MinGW” then add “C:\MinGW\bin”to your PATH in Windows.(安装路径加入环境变量)
3)  Now startyour Command Prompt and go the directory where you have your setup.py residing.
4)  Last andmost important step:
setup.py install build --compiler=mingw32
或者在setup.cfg中加入:
复制代码 代码如下:

[build]
    compiler = mingw32
 
C.gcc: /Zl: No suchfile or directory错误
异常信息如下
F:\devtools\MinGW\bin\gcc.exe -mno-cygwin-mdll -O -Wall -Dversion_info=(1,2,3,'
final',0) -D__version__=1.2.3"-IF:\devtools\MySQL\MySQL Server 5.5\include" -IC
:\Python27\include -IC:\Python27\PC -c_mysql.c -o build\temp.win-amd64-2.7\Rele
ase\_mysql.o /Zl
gcc: error: /Zl: No such file or directory
error: command 'gcc' failed with exitstatus 1

参数是vc特有的编译参数,如果使用mingw的话因为是gcc所以不支持。可以在setup_windows.py中去掉
/Zl
 
解决方法:
修改setup_windows.py  改为空的
复制代码 代码如下:

#extra_compile_args = [ '/Zl' ]
    extra_compile_args = [ '' ]

 目前就遇到这几个问题,望补充
 
3.  增删改查代码示例及结果(just for test)
复制代码 代码如下:

CREATE TABLE `user` ( 
  `Id` int(11) NOT NULL AUTO_INCREMENT, 
  `name` varchar(255) DEFAULT NULL, 
  `age` varchar(255) DEFAULT NULL, 
  PRIMARY KEY (`Id`) 
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8; 

复制代码 代码如下:

#dbtest.py 
#just used for a mysql test

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
