安装MySQLdb--MySQL-python

一、MySQLdb-python模块

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

`

二、安装依赖包

yum -y install python-devel mysql-devel

`

三、解压文件并修改site.cfg

tar -xf  MySQL-python-1.2.3.tar.gz

cd  MySQL-python-1.2.3

找到本地MySQL安装目录下的mysql_config，将site.cfg文件中mysql_config修改为该地址，并将threadsafe修改为False.

 

[root@localhost MySQL-python-1.2.3]# more site.cfg
[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 = 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/mysql/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

 

四、编译和安装

python setup.py build

python setup.py install

 

 

 

这里也有两种方式：

A.快速安装

B.自己编译

 

1.最快速最简单方法（赶时间的话）

 

sudo yum install MySQL-python

 

可能遇到问题：

>>> import MySQLdb

Traceback (most recent call last):

  File "", line 1, in ?

  File "MySQLdb/__init__.py", line 22, in ?

    raise ImportError("this is MySQLdb version %s, but _mysql is version %r" %

ImportError: this is MySQLdb version (1, 2, 3, 'final', 0), but _mysql is version (1, 2, 1, 'final', 1)

原因：之前使用编译的方法进行安装，下的是1.2.3，但是用yum目前最高1.2.1，冲突

解决方法：删除已经编译的文件

                  rm -rf MySQL-python-1.2.3/

再进行

>>> import MySQLdb

无错误，则表示成功了

 

 

 

2.自己编译安装（有时间的话。。。囧）

 

 

需要：

A.gcc

B.setuptools   

wget -O setuptools-0.6c8.tar.gz  http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c8.tar.gz

解压执行 sudo easy_install.py [或者 python setup.py build   && sudo python setup.py install]

C.python-dev   在   sudo apt-get install python-dev

   否则会报异常：fatal error: Python.h: 没有那个文件或目录

 

步骤：

A.下载：wget http://sourceforge.net/projects/mysql-python/files/latest/download

B.

$ tar xfz MySQL-python-1.2.3.tar.gz
$ cd MySQL-python-1.2.3

$whereis  mysql_config 

mysql_config: /usr/bin/mysql_config
$ vim site.cfg
修改mysql_config为mysql配置文件的路径 /usr/bin/mysql_config 

还要修改

 threadsafe = False
$ python setup.py build
$ sudo python setup.py install
