Python2.7.5 装配

安装python

1、下载python包并解压

wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz

tar –zxvf Python-2.7.3.tgz

2、 Configure安装目录

./configure

注:如果报configure: error: C compiler cannot create executables错误，则进行一下步骤。

export LIBS=

export CFLAGS=

如仍报错，则：yum install glibc-*

3、安装python

make all
make install
make clean
make distclean

验证安装版本：/usr/local/bin/python2.7 –V

4、配置系统默认python版本

mv /usr/bin/python /usr/bin/python-bak
ln -s /usr/local/bin/python2.7 /usr/bin/python

5、配置yum

vim /usr/bin/yum

将文件头部的
#!/usr/bin/python

改成

#!/usr/bin/python2.4

就可以继续使用yum了

安装MySQLdb模块

1、下载MySQLdb模块并解压

wget http://jaist.dl.sourceforge.net/project/mysql-python/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz

tar –zxvf MySQL-python-1.2.3.tar.gz

2、查看/usr/bin/mysql_config文件是否存在，不存在则需安装mysql的开发包

yum install mysql-devel

3、进入MySQL-python-1.2.3，编辑site.cfg

vim site.cfg

把#mysql_config = /usr/local/bin/mysql_config修改为

mysql_config = /usr/bin/mysql_config

4、安装MySQLdb模块

python ez_setup.py

python setup.py build

python setup.py install

5、测试安装是否成功

import MySQLdb
