Anybody know how to solve this error? it's the only error that i get when i try to run a python script or a django.wsgi script in a redhat system, after that i'm going to upload my web-app in a university server... and i've already configuret the VirtualHost. So that was the only problem, can anybody help please? Thank You.

有谁知道如何解决这个错误?这是我尝试在redhat系统中运行python脚本或django.wsgi脚本时得到的唯一错误,之后我将在大学服务器上传我的web应用程序...我已经配置VirtualHost。这是唯一的问题,任何人都可以帮忙吗?谢谢。

I found a solution for that problem (in redhat system), this is a solution in relation with Django framework..

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。

I've installed Python 2.6 (so i don't use anymore the default installed python), and reinstalled Django using the new version of Python and some other modules that were required like: (easy_isntall, MySQL_python-1.2.3-py2.6-linux-x86_64, setuptools, mod_wsgi-2.5) so after install all these modules should compare in the site-packages directory of Python 2.6: "/usr/local/lib/python2.6/site-packages".

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和一些其他所需的模块重新安装Django:(easy_isntall,MySQL_python-1.2.3-py2.6 -linux-x86_64,setuptools,mod_wsgi-2.5)所以安装完成后,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-packages”。

[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

Configure mod_wsgi to link with Python 2.6 shared libs

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

Then setting the environment variables:

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

Editing ~/.bashrc and adding some lines to keep the changes permanent:

编辑〜/ .bashrc并添加一些行以保持更改永久:

[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 Install:

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

Then, checking if the modules are correctly integrated:

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
