解决方法:

我找到了解决该问题的方法(在redhat系统中),这是一个与Django框架相关的解决方案.

我已经安装了Python 2.6(所以我不再使用默认安装的python),并使用新版本的Python和一些其他需要的模块重新安装Django：(easy_isntall,MySQL_python-1.2.3-py2.6 -linux-x86_64,setuptools,mod_wsgi-2.5)所以在安装之后,所有这些模块应该在Python 2.6的site-packages目录中进行比较：“/usr/local/lib / python2.6 / site-package”.

[root@lts5srv1 Python-2.6.8]# ./configure --enable-shared --prefix=/usr/local
[root@lts5srv1 Python-2.6.8]# make
[root@lts5srv1 Python-2.6.8]# make install

配置mod_wsgi以链接Python 2.6共享库

[root@lts5srv1 /]# cd /usr/local/lib/python2.6/config/
[root@lts5srv1 config]# ln -s ../../libpython2.6.so .

[root@lts5srv1 mod_wsgi-2.5]# ./configure --with-python=/usr/local/bin/python2.6
[root@lts5srv1 mod_wsgi-2.5]# make 
[root@lts5srv1 mod_wsgi-2.5]# make install

然后设置环境变量：

[root@lts5srv1 Python-2.6.8]# export LD_LIBRARY_PATH=/usr/local/lib/python2.6
[root@lts5srv1 Python-2.6.8]# export LD_RUN_PATH=/usr/lib64/httpd/modules

编辑〜/ .bashrc并添加一些行以使更改永久化：

[root@lts5srv1 ~]# vi ~/.bashrc

# .bashrc

# User specific aliases and functions

PATH=/root/epd-5.1.0/lib/python2.5:/root/epd-5.1.0/bin:${PATH}
PYTHONPATH=/usr/local/lib/python2.6
LD_LIBRARY_PATH=/usr/local/lib/python2.6
LD_RUN_PATH=/usr/lib64/httpd/modules

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

Django安装：

[root@lts5srv1 Django-1.4.1]# /usr/local/bin/python2.6 setup.py install

然后,检查模块是否正确集成：

[root@lts5srv1 /]# ldd /usr/lib64/httpd/modules/mod_wsgi.so
[root@lts5srv1 /]# ldd /usr/local/bin/python2.6
