老版本python2.6安装pip,psutil 报错问题。

今天在centos服务器上想做一个监控的小程序，首先想到的是用python来写这个小程序，服务器上的python版本很老，暂时没想升级。发现没有 psutil， 所以就像用这个三方的库。结果发现pip也没安装。好吧。一切从头开始.

一, 先安装setuptools.

wget --no-check-certificat  https://pypi.python.org/packages/source/s/setuptools/setuptools-2.0.tar.gz
tar zxf setuptools-2.0.tar.gz
cd setuptools-2.0
python setup.py install

二，安装pip

wget https://pypi.python.org/packages/source/p/pip/pip-1.3.1.tar.gz --no-check-certificate
tar -xzvf pip-1.3.1.tar.gz
cd pip-1.3.1
python setup.py install

三, 安装python-devel

yum install python-devel

如果不安装这个，在安装psutil的时候可能报错

四. 安装 psutil

pip install psutil
