python安装cx_oracle psutil插件等问题

机器上的python环境缺少部分插件，准备安装，root用户下面和普通用户下的python版本不一致（root为2.7.8 普通用户为2.6.6）

而且使用2.6.6安装报错 可能是缺少python-dev 。

查看了一下python2.6的sys.path，把之前测试环境安装成功的.so文件扔到目录 /usr/lib64/python2.6/site-packages下面就可以了

>>> import sys

>>> print sys.path

['', '/usr/lib64/python2.6/site-packages/msgpack_python-0.4.4-py2.6-linux-x86_64.egg', '/usr/lib/python2.6/site-packages/setuptools-7.0-py2.6.egg', '/usr/lib/python2.6/site-packages/python_dateutil-1.5-py2.6.egg', '/usr/lib/python2.6/site-packages/MarkupSafe-0.23-py2.6.egg',

'/usr/lib/python2.6/site-packages']

关于不同用户下的python版本问题有待继续整理
