cenots升级python麻烦死了,6.4也不更新下版本,死在2.6.6了,真Y的蛋疼啊~~~

先升级Python,执行

wget http://www.python.org/ftp/python/2.7.5/Python-2.7.5.tgztar zxvf Python-2.7.5.tgzcd Python-2.7.5./configuremake allmake installmake cleanmake distclean

目前的路径应该是/usr/local/bin/python2.7,顺便看下版本

/usr/local/bin/python2.7 -V

然后查下当前的版本

python -V

我这里显示的是2.6.6

mv /usr/bin/python /usr/bin/python2.6.6ln -s /usr/local/bin/python2.7 /usr/bin/python

现在再看下版本

python -V

应该显示2.7.5了吧

yum依赖修改

nano /usr/bin/yum

将头部的#!/usr/bin/python修改为#!/usr/bin/python2.6.6 即可.

安装setuptools

wget http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg --no-check-certificatesh setuptools-0.6c11-py2.7.egg

可能胡出现问题：

执行sh setuptools-0.6c11-py2.7.egg，后 显示 can t decompress data zlib not available 错误，

进入python2.7的下载目录重新编译，./configure ，make all ， make install

完后再执行sh setuptools-0.6c11-py2.7.egg ，完成egg安装。

安装pip

wget http://pypi.python.org/packages/source/p/pip/pip-1.0.2.tar.gz --no-check-certificatetar zxf pip-1.0.2.tar.gzcd pip-1.0.2python setup.py install

不知道最近怎么回事,下载python的东西,必须加--no-check-certificate.....

现在,可以很方便的使用pip install安装东西,例如

pip install pelicanpip install Markdown
python2.7，报错如下：
Traceback (most recent call last):
 File "/usr/local/bin/pip", line 9, in <module>
   load_entry_point('pip==1.4.1', 'console_scripts', 'pip')()

   from urllib2 import (Request, urlopen, URLError, HTTPError,
ImportError: cannot import name HTTPSHandle

处理：yum安装openssl和openssl-devel。然后重新编译python。
